Prenatal testing technologies in Australia: Unintended clinical and emotional complexities in underprepared systems

The past decade has seen technological advances in prenatal screening technologies rapidly integrated into clinical practice. These technologies have revolutionised healthcare and raised complex socio-ethical issues such as equitable access, medical commercialisation, and new eugenics. However, the important issue of the impact of these technologies on healthcare professionals is receiving less attention. Exploring this issue in the Australian context, we conducted a survey from August to November 2022, targeting health and allied health professionals who work with parents in the perinatal period who have received a fetal diagnosis. We received 75 substantive responses from a diversity of professionals, including sonographers, midwives, genetic counsellors and medical providers.In this article, we consider the unintended impacts of prenatal screening technologies on healthcare workers, drawing from Ziebland et al., ’s 2021 unintended consequences framework. Our reflexive thematic analysis produced three key themes: “Unintended Clinical Complexities”, “Adapting Work Practices to Keep Up in Systems that Lack”, and “Unintended Intensification of Emotional Labour”. Prenatal testing technologies have intentionally increased early testing and fetal information, offering veiled promises of increased certainty in pregnancy. However, our analysis highlights that these advancing technologies also generate more ambiguous results, creating unintended clinical and emotional complexities for healthcare providers. Workers must manage increased clinical uncertainty and constant change, creating intensified emotional labour in under-prepared systems. We conclude by identifying the need to recognise the impacts of advancing prenatal screening technologies on healthcare workers and for targeted professional training to prepare healthcare professionals for the complexities introduced by these new technologies.

Study Reviews Multilateral Installation Improvements on the North West Shelf

_ This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper OTC 32910,“A Decade of Multilateral Technology Installation Improvements Down Under,” by Stefano Cappiello and Adam Pasicznyk, SPE, Halliburton. The paper has not been peer reviewed. Copyright 2023 Offshore Technology Conference. _ Multilaterals wells on the North West Shelf of Australia have been installed for over a decade. An overview of the well architecture, technology evolution, reliability, and efficiency of these operations is presented in the complete paper. The study is focused on subsea multilateral campaigns, where multiple global and regional first installations took place in mature fields. Introduction Multilateral developments in Australia mainly have been completed off subsea installations, with fewer performed from jack-up rigs. These multilateral completions mostly have been installed with the junction located in the producing reservoir sands. Technology Advancement of Multilaterals (TAML) Level 5 completions have successfully been deployed. The authors classify related systems as follows, with the most attention paid in the synopsis to the final two classes: - Generation One (Field A) - Generation Two (Field B) - Generation Three (Field C) - Generation Four (Field A) General Multilateral Well Design Because of sand production within the reservoir, these applications typically require a TAML Level 5 completion system. These systems deliver hydraulic and mechanical isolation at the junction through the completion. The junction is isolated above and below by production packers and by swell packers in the lateral. The junctions typically are installed horizontally within the reservoir. The original general requirements to construct Level 5 multilateral junctions included the following: - Ability to construct a Level 5 Junction in the 9⅝-in. casing or liner - Ability to run a landing profile or coupling as part of the 9⅝-in. production casing or liner - Ability to run and orient a premilled window at depth - Drill-out 8½-in. openhole section into the mainbore and into the lateral - Junction installed within the reservoir at high angle - Window milling to be performed in one trip - Lateral completion to be installed in one trip - Compressive strength rating capable of running screen sections over 2 km As the operators began to adopt multilateral technology in Australia, the following requirements were incrementally added: - Ability to deliver a Level 5 multilateral system in an existing well - Ability to deliver a trilateral well - Improve efficiency and reduce installation time

Discrete Element Method Simulation of the Idaho Calcine Simulant for Hot Isostatic Pressing Canister-Filling Process: Part 1

In preliminary engineering studies and equipment commissioning, readily available simulants with certain resemblances to the target waste, such as particle size, may be employed. However, for the validation of engineering processes, it is crucial to use simulants that closely replicate the physical and flow characteristics of the waste material, typically excluding radioactivity. The production of such simulants can entail significant costs. To facilitate the development of novel engineering solutions, the U.S. Department of Energy provided a nonradioactive alumina calcine simulant. This simulant was utilized to demonstrate a hot isostatic press (HIP) canister-filling system designed by Gravitas Technologies in Australia. The simulant was synthesized through a fluidized-bed calcination process, which mirrored the chemistry and procedure employed for the actual alumina Idaho calcine waste material. Consequently, the simulant exhibited physical properties akin to the actual calcine, including particle size distribution, bulk density, and flow properties. This first paper, Part 1, presents the powder characterization test results determined by a Freeman FT-4 rheometer and the calibration methods that determined a set of unique contact model parameters for dynamically simulating Idaho calcine simulant in a discrete element method (DEM) model. The second paper, Part 2, will present the dynamic simulations of two bulk material-handling scenarios in a full-scale, three-dimensional integrated HIP canister-filling system. The predicted results are compared with historical experimental results for validating the contact model. The contact model, which represents the particle-particle and particle-boundary interactions, was calibrated according to experimental data obtained from six calibration tests. This work aims to support future research with powder characterization experimental data and a calibrated DEM contact model to assist in developing processes for the safe handling and treatment of Idaho calcine waste.

Making recommendations to subsidize new health technologies in Australia: A qualitative study of decision-makers’ perspectives on committee processes

ObjectivesTo explore experiences of, and perspectives on, health technology assessment (HTA) processes used to produce recommendations about subsidizing new medicines, and medical technologies in Australia, from the perspectives of those experienced in these processes. MethodsSemi-structured interviews with a diverse group of 18 informants currently or previously members of the Pharmaceutical Benefits Advisory Committee (PBAC) or the Medical Services Advisory Committee (MSAC). Participants were interviewed September 2021-February 2022. Transcripts were analyzed using reflexive thematic analysis. Results3 major themes were identified: contrasting technical and decision-making stages, resisting reductionist approaches, and navigating decision-making trade-offs. Participants discussed the complexities of the evaluative HTA process, especially when considering uncertainty in the evidence. As part of the current process, a deliberative decision-making stage was considered essential, allowing a flexible approach to decision making to consider factors beyond strength and quality of quantifiable data in the technical evaluation. Participants acknowledged these less-quantifiable factors were sometimes considered implicitly or were difficult to describe and this, paired with commercial in confidence requirements, presented challenges with respect to the desire to increase transparency. Conclusion (s)As HTA processes for new medicines and medical technologies in Australia continue to be reviewed, the balance between retaining flexibility during deliberation, confidentiality for sponsors and the public's desire for greater transparency may be a fruitful area for continuing research.

Preliminary Results in Innovative Solutions for Soil Carbon Estimation: Integrating Remote Sensing, Machine Learning, and Proximal Sensing Spectroscopy

This paper explores the application and advantages of remote sensing, machine learning, and mid-infrared spectroscopy (MIR) as a popular proximal sensing spectroscopy tool in the estimation of soil organic carbon (SOC). It underscores the practical implications and benefits of the integrated approach combining machine learning, remote sensing, and proximal sensing for SOC estimation and prediction across a range of applications, including comprehensive soil health mapping and carbon credit assessment. These advanced technologies offer a promising pathway, reducing costs and resource utilization while improving the precision of SOC estimation. We conducted a comparative analysis between MIR-predicted SOC values and laboratory-measured SOC values using 36 soil samples. The results demonstrate a strong fit (R² = 0.83), underscoring the potential of this integrated approach. While acknowledging that our analysis is based on a limited sample size, these initial findings offer promise and serve as a foundation for future research. We will be providing updates when we obtain more data. Furthermore, this paper explores the potential for commercialising these technologies in Australia, with the aim of helping farmers harness the advantages of carbon markets. Based on our study’s findings, coupled with insights from the existing literature, we suggest that adopting this integrated SOC measurement approach could significantly benefit local economies, enhance farmers’ ability to monitor changes in soil health, and promote sustainable agricultural practices. These outcomes align with global climate change mitigation efforts. Furthermore, our study’s approach, supported by other research, offers a potential template for regions worldwide seeking similar solutions.

P078 “It’s very good but it needs to be better”: Usability and Acceptance of Fatigue Detection Technology in Australia.

Abstract Introduction Fatigue detection technology (FDT) is commonly used in the Australian road transport industry to monitor and/or detect driver fatigue. These devices typically provide alerts to drivers and their organisation if fatigue is detected and aim to reduce incidences of fatigue-related vehicle crashes and/or improve driver behaviour. The rise of these technologies is generating debate about how their relative design and merit might be evaluated. However, little is known about the experiences of individuals who use FDTs, including perceptions of use, acceptance, and effects on driver behaviour. The Australian Automobile Association funded the research into FDTs from which this presentation draws. Methods Semi-structured interviews were conducted with a range of existing users of FDT (n = 28) between November 2022 and June 2023. Participant groups included drivers (n = 17), middle managers and data users (n = 7), and executives (n = 4) from different commercial organisations that were trialling or had adopted FDT. Results Preliminary thematic analysis has identified a range of factors underlying driver and organisational acceptance of FDTs. These include: data privacy, vendor support, technical merit, training load, intrusiveness, and cost. Drivers perceived their behaviour to be moderately impacted by FDT in positive and negative ways. This included impacts on sleep/wake behaviour, in-cab activities, and driving performance. Certain types of FDT were considered highly contentious by all existing user groups. Discussion FDT adds further complexity to the contentious topic of fatigue management for professional drivers. Findings highlight a range of implications for FDT adoption and effective evaluation.

Human Interpreters in Virtual Courts: A Review of Technology-Enabled Remote Settings in Australia

Objective: This interdisciplinary review intends to inform legal scholars, practitioners, and users of language interpretation services in the judiciary of challenges encountered by professional interpreters in virtual hearings and remote settings.Methods: Situated at the intersection of law, language, and communication, this review analyses the latest discourses about technology-enabled remote settings and synthesises insights into recommended practices in effective legal communication mediated by interpreters in virtual courts.Results: With an overarching aim to improve effective collaboration between interpreting service providers and users in multilingual legal communication for procedural equity and access to justice, this review establishes three central claims: (1) the technology-enabled virtual hearings is accelerated by the covid-19 pandemic, (2) the need for effective legal communication mediated by the use of interpreters in remote settings is mounting, and (3) successful collaboration between the service user and provider can achieve a win-win outcome.Scientific novelty: A review of existing studies in law and language reveals three main gaps: (1) procedural justice in videoconferencing hearings and remote technologies, (2) equity and access for people with limited proficiency in the official language of the court system, and (3) effective legal communication mediated by human interpreters in virtual courts. This review bridges the existing gaps in knowledge.Practical significance: it touches on three aspects of the law-language nexus: (1) Covid-19 accelerated adoption of the virtual courtroom technologies in Australia and its impact on court interpreting, (2) challenges for interpreters in remote settings, and (3) achieving linguistic accuracy and intercultural appropriateness when preserving the manner in which the content is expressed as intended or implied by the original speaker. Grounded in courtroom interpreting practices, it highlights the importance of effective collaboration in successful multilingual legal communication rooted in mutual purpose, shared expectations, and interprofessional understanding.

In their own words: A qualitative study of users’ acceptance of connected vehicle technology after nine months of experience with the technology

The Ipswich Connected Vehicle Pilot (ICVP) was the largest on-road trial of connected vehicle technology in Australia. In the ICVP, 355 privately-owned vehicles were outfitted with connected vehicle technology and driven for 9 months with 326 participant vehicles remaining in the study until completion. User acceptance is as a key determinant of the future effectiveness of connected and co-operative Intelligent Transport systems (C-ITS) given it impacts likely uptake of these vehicles and the optimal functioning of such systems is contingent on widespread uptake by the public. This paper presents the findings of two qualitative studies conducted as part of the ICVP, comprising 53 individual interviews and 14 focus groups/interviews with 47 participants. The purpose of the qualitative studies was to understand users’ perceptions of the system as well as their acceptance of C-ITS in general. Overall, participants were generally positive towards the system, could appreciate the safety benefits it offers, and expressed interest in adopting the technology presuming future systems would be refined. Some participants reported that they missed the warnings provided by the system once the technology had been removed. Participants wanted the system to be seamlessly integrated in their vehicle and have features that enabled personalisation. Participants identified that some of the warnings, most notably the advanced red light warning, were presented too late or at inaccurate times indicating that these issues must be remedied to ensure successful future implementation of C-ITS. Participants appreciated that data sharing would optimise the system but wanted controls to be put in place to guard against misuse; participants did not want their data to be used for sales or marketing purposes. Users’ experience and perceptions are key to ensuring wider-spread adoption of C-ITS. The findings thus have important implications for future C-ITS implementation to ensure that the benefits of C-ITS are optimised to facilitate wide-spread penetration of the technology.

Understanding the risks of China-made CCTV surveillance cameras in Australia

ABSTRACT In the global interconnected economy, China-made information-collecting technologies such as closed-circuit television (CCTV) surveillance cameras have become popular products for routine video-based surveillance. Hikvision and Dahua are the two largest global suppliers of CCTV cameras, with both companies supplying their products to over 200 countries. Despite their popularity, national security concerns are commonly cited when adopting these cameras, citing manufacturer links with the Communist Party of China (CPC), cybersecurity vulnerabilities, and sales recorded in the Xinjiang region, that has records of human rights violations. This paper is structured in three parts: first, we explore the predominance of China-made information-gathering technologies in Australia; second, we summarise common national security concerns usually associated with China-based technology manufacturers; and third, we propose regulatory measures to regulating China-made CCTV cameras in Australia. The paper suggests that while state and Federal decision-makers are free to remove Chinese CCTV surveillance cameras, they should avoid overt politisation. Overall, a stronger focus should be placed on evaluating cybersecurity risks of Internet of Things (IoT) information-collecting technologies and considering their timely and effective regulation from the perspective of individual and national interests.

Current endodontic practice and use of newer technologies in Australia and New Zealand.

This study investigated endodontic clinical preferences, adoption of newer technologies and information sources among dentists and endodontists. Dental and endodontic society members in Australia and New Zealand were surveyed online regarding their endodontic treatment preferences, armamentarium, information sources and continuing professional education (CPE) attendance. Complete responses were received from 71 endodontic specialists or postgraduates (Group E) and 139 general dentists (Group D). Most of Group E used dental operating microscopes (95.8%), endodontic cone-beam computed tomography (CBCT; 98.6%) and calcium silicate-based materials (CSBMs; 97.2%), significantly more (P < 0.001) than Group D (86.3% used loupes, <32% used CBCT for endodontics or CSBMs). Most respondents used dental dam always for endodontics (94.3%), electronic apex locators (EAL; 81.0%) and engine-driven nickel-titanium (NiTi) instruments (91.4%); Group E had more experience with engine-driven NiTi (P < 0.001). Endodontic CPE attendance was highest at dental association programs (P < 0.001) while hands-on NiTi training attendance was highest via commercial companies (P < 0.05). Online information sources were commonly used (38.8% of Group D, 59.2% of Group E). Dental dam, EAL and engine-driven NiTi were almost universally used. The endodontic group reported high adoption of newer endodontic technologies. Endodontic CPE and information sources should be further surveyed as online engagement evolves. © 2023 Australian Dental Association.

Establishing the normative and comparative needs of assistive technology provision in Queensland from the agency and funding scheme perspective.

Assistive technology services and devices support the participation and inclusion of people living with disability. In Australia, the regulatory bodies, agencies and schemes that manage assistive technology provision are governed by national and / or state-based Acts and Legislation. This study examined the assistive technology sector from the perspective of the regulatory bodies, agencies and schemes. Regulatory bodies, agencies and schemes that manage funding for assistive technology in Australia were identified by the research team. A website audit reviewed publicly available documents and information. Semi-structured interviews with representatives from the agencies and schemes were audio-recorded and transcribed verbatim. The audit (n =17) found that the range and level of information publicly available was variable. The availability of assistive technology for driving and transport, design and building for access and safety, and mobility was most often promoted. The qualitative findings (n = 11) indicated variability and challenges within four themes: operationalising the legislation; internal assistive technology processes; reasonable and necessary; and risks in the assistive technology pathway. Regulatory bodies, agencies and schemes are critical to the effectiveness of the sector. The findings identified opportunities for the organisations to review how internal processes are communicated publicly, and for the sector to address the perceived risks related to health professional availability, knowledge and skills, and limited accessibility to trial assistive technology. Subsequent studies explored the perspectives of the assistive technology advisors and suppliers and the recipients of assistive technology services and devices.

Practice insights for the responsible adoption of smart farming technologies using a participatory technology assessment approach: The case of virtual herding technology in Australia

CONTEXTThe concept of responsible innovation is gaining traction in the Smart Farming field to address emerging socio-ethical issues such as power asymmetries between farmers and technology development companies in farm data ownership, and animal welfare issues arising from the automation of livestock management. Responsible innovation involves the democratisation of science and decision making for societal control of innovations. The application of responsible innovation principles to the adoption phase of Smart Farming technologies is an under explored area in terms of defining what responsible adoption practices are for Smart Farming, and with what effect. OBJECTIVEThis empirical research aims to provide insights into what responsible adoption practices might involve, based on application of a responsible innovation approach to designing a cross-industry adoption strategy for a virtual fencing technology in Australia. This case study also examines what responsible adoption practices mean for enacting responsible innovation of Smart Farming technologies more broadly. METHODSA participatory Technology Assessment (pTA) approach engaged a range of virtual fencing technology end-users (livestock producers) and stakeholders (agricultural advisers, natural resource managers, food retailers, a food processor, and state government department staff) (n = 80). The participants identified and considered the benefits and risks of implementing a specific virtual fencing product in various contexts. The engagement methods were 12 interactive workshops organized in peer/sector groups and one reflective and deliberative consultation process with 13 adoption specialists and practitioners to define an adoption pathway for virtual herding technology. RESULTS AND CONCLUSIONSThe adoption of the virtual herding technology product requires multiple levels of support to ensure that the technology is used responsibly and generates private, industry and public goods. This prospective knowledge, built from the considerations of end-users and stakeholders, was integrated into a virtual herding adoption strategy, and accounted for animal welfare concerns, the empowerment of producers to lead their own adoption support network and the desire for some form of regulatory governance. The responsible adoption practices were limited by the lack of institutional pathways to mobilise the strategy beyond the life of the research project. SIGNIFICANCEThe research indicates that there is value in further pursuing the notion of responsible adoption practices for Smart Farming technologies. These practices need to be designed for understanding the complexity of the adoption situation, testing the assumptions about what the ‘right’ adoption pathway should be, and inclusive participation in the ongoing governance of adoption pathways.

Critical Challenges and Potential for Widespread Adoption of Mass Timber Construction in Australia—An Analysis of Industry Perceptions

The construction industry is one of the largest producers of greenhouse gases, accounting for 38% of global carbon emissions. Recently, interest in mass timber construction has grown, due to its potential benefits in reducing environmental impact compared to traditional construction methods that use steel and concrete, and in promoting global sustainability and climate agendas, such as the Sustainable Development Goals (SDGs) and global net-zero emissions by 2050. Despite the slow adoption of mass timber construction (MTC) in Australia, some innovative and iconic projects and initiatives have been realised. The research intends to identify critical challenges and potential for broader adoption of MTC in Australia. The study reviewed selected MTC projects, followed by a perception survey and interviews of the relevant industry stakeholders in Australia to understand the key barriers and enablers for the widespread application of MTC in Australia. Significant challenges identified in the research include a lack of understanding of fire safety, regulations, performance, inherent application, and local manufacturers and suppliers, which are yet to be improved. In addition, it was found that prior experience built confidence in the application of MTC. Furthering widespread adoption of MTC technology in Australia beyond cost competitiveness requires the Australian construction industry to work towards developing suitable regulatory and insurance policies, financing, incentivising clients, and a skilled workforce. The study focuses on an investigation in the context of industry perceptions of MTC in Australia. Based on the analysis of the critical characteristics of MTC projects, and using the empirical data, the study identifies key challenges and opportunities in the widespread application of MTC in Australia.

Designing energy futures: a participatory foresight study in Australia

PurposeThis paper aims to: first, it studies expert opinions about the future of clean, decentralized energy technology in Australia; second, develop an interpretive and participatory foresighting methodology for a forthcoming study.Design/methodology/approachThis paper reports a forecasting study about the future of clean energy. Driven mostly by economics and changing carbon policies, the energy sector is currently moving from fossil fuels to a variety of cleaner technologies. Energy experts have several incommensurate interpretations of how this change will happen. This paper describes the first phase of an ongoing study that foresight clean energy futures in Australia. By building on a participatory method in a scientific expert community, it describes the path from technological presumptions into four parallel yet interconnected scenarios. The paper also explores the social drivers behind these scenarios.FindingsFirst, energy experts in Australia classify futures into four main scenarios: abundant, where energy will be mostly produced by solar cells; traded, where the future of energy lies in virtual power plants and microgrids; circular, which targets Australia’s NetZero goals through biomaterials, carbon capture and new powerful; secure, which secures the country’s energy supply through coal and nuclear energy. Second, they locate policy as the most important form of wildcards. The policy is multilayered from local to US politics and falls outside the scope of forecasting.Research limitations/implicationsThe most important limitations of the study are: first, its reliance on scientific and technological experts, which guarantees its scientific validity but may underrepresent the social drivers of energy; second, this study is a methodological pilot of a larger study that will target industrial, commercial and local drivers; third, its focus on Australia, where politics, the size of the country and climate shape the uptake of clean energy in specific ways, most notably in the case of rapid uptake of solar energy.Practical implicationsThe main practical implications of the paper are its broad focus on clean energy futures and its participatory foresighting approach, which can be repeated in other studies.Social implicationsThe main social implication of the study is that it clearly shows that a technological perspective is necessary but not sufficient in understanding the future of clean energy. The paper also shows that local drivers importantly mold the future and should be taken into account in future studies and policy.Originality/valueThis paper makes two contributions. First, it organizes several technologies into four scenarios that clarify Australia’s clean energy futures better than a piecemeal study would do. Second, it developed and piloted an interpretive participatory methodology for studying futures by building on references from design research. This methodology will be used in subsequent studies.

Clinical gene technology in Australia: building on solid foundations.

Clinical gene technology in Australia: building on solid foundations.

20 Years of Legislation - How Australia Has Responded to the Challenge of Regulating Genetically Modified Organisms in the Clinic.

•In contrast to the prior voluntary system, since 2001, gene technology in Australia has been regulated under a legislated national Gene Technology Regulatory Scheme which is administered by the Gene Technology Regulator.•The Scheme provides science-based assessment of the potential risks of gene technology to the health and safety of people and the environment.•It complements the role of the Australian Therapeutic Goods Administration which regulates all therapeutic products in Australia to ensure they are safe and effective.•Recent reforms to the Scheme contribute to, and anticipate, the continued safe development and delivery of gene-based human therapeutics in Australia as a successful model for other jurisdictions.

"We're Still Struggling a Bit to Actually Figure Out What That Means for Government": An Exploration of the Policy Capacity Required to Oversee Robot Technologies in Australia and New Zealand Care Services.

Many countries are experiencing a “care crisis” driven by increasing demand for care services alongside difficulties in recruiting and retaining an appropriate care workforce. One of the solutions offered to this is the use of robotic technologies. While there are several positives produced by robots, they are not without challenges and have the potential to be misused. History shows disruptive technologies require appropriate policy capacity for these to be effectively stewarded so that we can secure the positive gains of these without encountering potential harms. In this paper, we explore the types of policy capacity needed to oversee robotic technologies. Drawing on interviews with 35 key stakeholders involved with the implementation of robots in Australian and New Zealand care services, we identify the capabilities required at the individual, organisational, and systemic levels across the analytical, operational, and political domains. We found the respondents perceived a lack of policy capacity to oversee robotics in the government. However, these gaps are less in respect to technological skills and abilities and more in respect to the system’s impacts and effects of these technologies. We conclude by outlining a summary of the capabilities required to oversee robots in complex care systems.

Artificial Intelligent Technologies for the Construction Industry: How Are They Perceived and Utilized in Australia?

Artificial intelligence (AI) is a powerful technology that can be utilized throughout a construction project lifecycle. Transition to incorporate AI technologies in the construction industry has been delayed due to the lack of know-how and research. There is also a knowledge gap regarding how the public perceives AI technologies, their areas of application, prospects, and constraints in the construction industry. This study aims to explore AI technology adoption prospects and constraints in the Australian construction industry by analyzing social media data. This study adopted social media analytics, along with sentiment and content analyses of Twitter messages (n = 7906), as the methodological approach. The results revealed that: (a) robotics, internet-of-things, and machine learning are the most popular AI technologies in Australia; (b) Australian public sentiments toward AI are mostly positive, whilst some negative perceptions exist; (c) there are distinctive views on the opportunities and constraints of AI among the Australian states/territories; (d) timesaving, innovation, and digitalization are the most common AI prospects; and (e) project risk, security of data, and lack of capabilities are the most common AI constraints. This study is the first to explore AI technology adoption prospects and constraints in the Australian construction industry by analyzing social media data. The findings inform the construction industry on public perceptions and prospects and constraints of AI adoption. In addition, it advocates the search for finding the most efficient means to utilize AI technologies. The study helps public perceptions and prospects and constraints of AI adoption to be factored in construction industry technology adoption.

Quantifying the Lost Safety Benefits of ADAS Technologies Due to Inadequate Supporting Road Infrastructure

Advanced driver assistance systems (ADAS) provide warnings to drivers and, if applicable, intervene to mitigate a collision if one is imminent. Autonomous emergency brakes (AEB) and lane keep assistance (LKA) systems are mandated in several new vehicles, given their predicted injury and fatality reduction benefits. These predicted benefits are based on the assumption that roads are always entirely supportive of ADAS technologies. Little research, however, has been conducted regarding the preparedness of the road network to support these technologies in Australia, given its vastly expansive terrain and varying road quality. The objective of this study was to estimate what proportion of crashes that are sensitive to AEB and LKA, would not be mitigated due to unsupportive road infrastructure, and therefore, the lost benefits of the technologies due to inadequate road infrastructure. To do this, previously identified technology effectiveness estimates and a published methodology for identifying ADAS-supportive infrastructure availability was applied to an estimated AEB and LKA-sensitive crash subset (using crash data from Victoria, South Australia and Queensland, 2013–2018 inclusive). Findings demonstrate that while the road networks across the three states appeared largely supportive of AEB technology, the lack of delineation across arterial and sub-arterial (or equivalent) roads is likely to have serious implications on road safety, given 13–23% of all fatal and serious injury (FSI) crashes that occurred on these road classes were LKA-sensitive. Based on historical crash data, over 37 fatalities and 357 serious injuries may not be avoided annually across the three Australian states based on the lack of satisfactory road delineation on arterial and sub-arterial (or equivalent) roads alone. Further, almost 24% of fatalities in Victoria, 24% of fatalities in Queensland and 21% of fatalities in South Australia (that are AEB- or LKA-sensitive) are unlikely to be prevented, given existing road infrastructure. These figures are conservative estimates of the lost benefits of the technologies as they only consider fatal and serious injury crashes and do not include minor injury or property damage crashes, the benefits of pedestrian-sensitive AEB crashes in high-speed zones or AEB fitted to heavy vehicles. It is timely for road investments to be considered, prioritised and allocated, given the anticipated penetration of the new technologies into the fleet, to ensure that the road infrastructure is capable of supporting the upcoming fleet safety improvements.
