Detection of Spatiotemporal Interferences of Road Traffic with IoT-Connected Sensor Beacons

Abstract Efficient collection and real-time provision of information on roadworks with impact on traffic flow are essential to reliable and effective traffic and transport management for urban and regional road networks. In order to enable road operators to impose efficient traffic management measures, comprehensive amounts of data on both traffic demand and interferences of the road infrastructure are required. Roadworks management systems are used for planning of construction work zones, whereas exact real-time information on opening, spatial-timely progress and completion of roadworks are only to obtain by connected sensors to be deployed directly in the work zone. To that end, an innovative sensor-based construction barricade light - in the following denoted as sensor beacon - has been developed which allows the geo-referencing of road works in real time with sub-meter accuracy. The combined use of multiple connected sensor lights allows the extent of the work site to be exactly mapped. The construction site related information is provided to an urban data platform for further processing with software systems for roadworks information and coordination.

Influence of rock properties on emission rate of Particulates Matter (Pm) during drilling operation in surface mines

The mining process generates significant amount of dust in the form of particulate matters into the atmosphere. Out of different mining process, opencast mining produces more dust than that of underground mining because of exposure in the ambiance. The mining operations are directly or indirectly involved in the production of dust particles. The activities like drilling operation, Blasting and haul road operations produce fugitive dust and causes significant deterioration of mine atmosphere. This fugitive dust consists of particulate matters (PM), which are more harmful to the human respiratory system. The prevention measures is only possible when the actual prediction of emission of those fugitive dust particles are possible. There is several model that predict the emission of the dust particles, but there is very less model to predict fugitive dust produced from a drilling operation in surface mines. In this paper, study was carried out to develop dust prediction model and to assess the influence of rock properties on dust emission. Based on the results obtained the developed model exhibit close proximity of predicted as well as field measured values with a regression coefficient of 0.75. Thus, the development of the model with effective prediction capability is the novelty of this paper. Decrease in dust emission rate was observed with increased moisture content present in drill cuttings, higher compressive strength, and density.

On the quantitative relationship of the in-cylinder heat to work conversion process of natural gas spark ignited engine under steady state and transient operation conditions

The performance characteristics of an automotive engine under the road operation conditions, i.e. under transient torque and power output conditions, as well as the instant in-cylinder thermal to work conversion efficiency, are very important for the vehicle’s performance and fuel economy, but difficult to measure. In an effort to identify and confirm the quantitative relationships between the engine performance parameters with controlling and operating parameters (such as the engine speed, intake pressure, lambda and so on) for natural gas spark ignited engines, the controlling equations of the in-cylinder indicated thermal efficiency and indicated mean effective pressure are derived. The results show that the derived controlling equations also demonstrate good agreement with experimental data under both steady state and transient operation conditions. This research confirms the feasibility to identify indirectly the natural gas spark ignited engine’s performance under the road conditions through analyzing the measureable or available controlling and operational parameters, and provides a method for on-line analysis and optimization of the engine operation parameters.

GEOTECHNICAL ACCIDENTS OF ROAD STRUTURES AND THEIR LICVIDATION

Geotechnical accidents often occur during road operation. To eliminate their consequences, various measures are required, taking into account the geological features of the site. Three cases of geotechnical accidents of road structures are considered: landslide damage to the bridge cone and the slope of the road embankment; the formation of a local landslide, plastic deformation and loss of stability of the roadbed, settlement of the culvert links; suffusion from the side of the railway cut under the cone of the bridge structure due to damage to the anti-filtration clay screen. In the first case, the reasons for the intensification of the landslide were periodic rises in the level of groundwater, the presence of areas not protected by vegetation, and areas of loose soil. The accident was eliminated by installing an anti-landslide structure made of bored piles, embedded with their lower ends into rocky ground. In the second case, the reasons were waterlogging due to heavy summer rains and melting snow next spring. To eliminate the accident, drainage was arranged in the adjacent territory; the soil was partially replaced, reinforcement with geotextiles was carried out, slopes with a berm were laid, the base of the subgrade was strengthened. In the third case, the removal of soil particles (suffusion) from the side of the railway excavation under the cone of the bridge structure occurred due to damage to the anti-filtration clay screen during the creation of the construction site. After the restoration of the screen and the drainage device, the suffusion was eliminated. The above examples show the importance of engineering and geological substantiation in the design of transport construction facilities.

Innovations in the technology for producing asphalt concrete based on neutralized catalyst as a condition for improving the quality of road surfaces

The conditions of safety and environmental friendliness of the operation of roads as an international key problem of our time are disclosed. Objective reasons are shown that reduce the quality indicators of the construction and operation of roads. A call to the technology for producing asphalt concrete based on spent alumina-chromium catalysts is a timely need, due to the increasing requirements of international and Russian standards for the quality of roads and their operating conditions. The main scientific idea is to obtain asphalt concrete based on reduced aluminum-chromium catalyst to improve the quality of road surfaces.A safe method is proposed for converting toxic waste into safe raw materials, taking into account the conversion of chromium (VI) compounds to chromium (III), which makes it possible to use it as part of asphalt concrete coatings. The optimal amount of alumina-chromium catalyst in the composition of asphalt concrete (6.4 ÷ 12.5 wt. %) is shown. It is proved that the use of reduced aluminum-chromium catalyst in the composition of asphalt concrete increases the proportion of waste in the total raw material balance, expands the range of building materials used in atmospheric conditions.Samples of asphalt concrete mixtures were prepared and tested according to ISST 9128-97 with the use of spent catalyst additives.The analysis of the current state of road surface coating technology is carried out. The optimal formulation for the preparation of asphalt mixes based on the spent catalyst having indicators of physical and mechanical properties is better than a standard sample of asphalt concrete. An effective method is proposed for removing toxic hexavalent chromium from spent catalyst as waste by transferring it to non-toxic trivalent chromium. One of the long-term problems of improving the quality of road surfaces with the inclusion of reconditioned spent aluminum-chromium catalysts, as a solution to the industrial and environmental safety of an industrial enterprise and improving the quality of operation and durability of road surfaces has been solved.

Modes of operation of toll gate lanes on toll roads

The article presents a detailed analysis of the modes of operation of toll gate lanes on toll roads. The toll gate lane has such operating modes as manual and automatic. Also, the lane can work in free mode – any vehicles can pass without classification and payment. The lane in closed mode does not accept vehicles. Ways of charging for each option are described, namely manual, automatic, and electronic. The stages of passing through the lane in different modes and their transport capacity are presented. The characteristic features of toll systems are highlighted and described. The purpose of the lane equipment elements is to control the flow of vehicles through the toll gate, as well as to accept tolls using various payment methods. The selection of toll system and locations of toll gates is based on an assessment of economic feasibility and taking into account the estimated traffic and traffic flow structure, the number and location of traffic interchanges. Special attention is paid to the criteria for selecting a toll system, which is to maximize profits from the operation of a toll road.

Lessons learnt from green public procurement in the Norwegian construction sector

Introduction. Over the next 5 years, Norway shall construct roads, rail tracks and buildings for up to 300 bNOK. Statens vegvesen (SVV), the Norwegian road authority, has calculated that construction, operation and maintenance of Norwegian roads are responsible for 1.5-2m tCO2eq/yr. SVV also found a correlation between cost and emissions and found that every 1MNOK invested leads to ca. 35tCO2eq. When considering the national transport plan (NTP), this equates to 10% of Norway’s climate budget. In order to reach climate mitigation goals, public developers have initiated environmental measures in public procurement to reduce GHG emissions. Methods. This paper collects, compares and reviews environmental criteria written into Norwegian public procurement to see which measures are being implemented, how they are being implemented, and to discuss how effective these measures are in cutting GHG emissions. Contracts are sampled from major public developers in the Norwegian construction sector. Results. The results show that public procurers use a range of tools to facilitate for emission reductions. Conclusions. This paper reviews environmental measures in public procurement of Norwegian construction. Lessons learnt may be spread to other countries and the private sector. Grant support. None.

Travel Time Reliability of Bus Operation in Heterogeneous Traffic Conditions of Dar es Salaam City, Tanzania

Abstract The assessment of travel time reliability enables precise prediction of travel times, better activity scheduling and decisions for all users of the road network. Furthermore, it helps to monitor traffic flow as a crucial strategy for reducing traffic congestion and ensuring high-quality service in urban roads. Travel time reliability is a useful reference tool for evaluating transport service quality, operating costs and system efficiency. However, many analyses of travel time reliability do not provide true travel variation under heterogeneous traffic flow conditions where traffic flow is a mixture of motorized and non-motorized transport. This study analysed travel time reliability under heterogeneous traffic conditions. The travel reliabilities focused on passenger waiting time at bus stops, in-vehicle travel time, and delay time at intersections which were analysed using buffer time, standard deviation, coefficient of variation, and planning time. The data used were obtained from five main bus routes in Dar es Salaam. The results indicate low service reliability in the outbound directions compared to inbound directions. They also intend to raise awareness of policy-makers about the situation and to make them shift from expanding road networks towards optimising road operations.

Road network forms specific stations for living organisms in the conditions of the steppe zone

The state of art analysis of available published data allowed to determine the features of the roadside ecosystems formation and the possibility of further development of biodiversity conservation measures. In Ukraine and around the world, road infrastructure is an important economic and social object that has a negative impact on the environment. This takes place due to environmental pollution, fragmentation of habitats, biodiversity loss, etc. At the same time, on the roadsides the stations (microhabitats) are being formed. They can be a barrier to motor vehicle pollution and provide available shelters for living organisms. Road operation usually affects the structure of roadside vegetation. There is an increase in the number of of annual plant species and a decrease in perennials. Favourable conditions are also created for the spread of heliophytes and xerophytes. Roads are a source of chemical pollution that affects all components of roadside ecosystems. The amount of pollutants is mainly dependent on the traffic intensity and road width. The creation of roadside forest plantations significantly reduces the negative impact of vehicles. Wood plantations contribute to better carbon deposition, which is an integral part of many vehicle pollutants, and create a barrier for pollutants coming far from roads. Forest belt can also be a refuge for many species of animals and combine fragmented habitats around. Because plants and small animals at roadside stations are bound to their localities, they are able to accumulate much amount of ecotoxicants, especially heavy metals, which should be taken into account when conducting local business. For the living of animals in roadside stations, the characteristics of specific confined plant community, microclimate and landform are quite important. Due to the linearity and long distances, roadsides provide migration ways for many species. The developed roadside habitats may be the refugia for not only common, but for rare animals. We should conclude that further research of the environmental benefits of roadside ecosystems in the Steppe zone of Ukraine would allow developing effective measures for roadside management in the frames of nature conservation.

Discussion on Construction Technology of Road Subgrade in Civil Engineering

Only by comprehensively ensuring the quality of road subgrade can the road performance be effectively improve and the development of urban construction be ensured. The quality of subgrade determines the traffic capacity of urban roads and plays a decisive role in the safety and stability of traffic. This article mainly analyzes the problems of road subgrade construction in civil engineering, and comprehensively puts forward countermeasures, so as to effectively improve the subgrade construction quality and ensure the smooth operation of roads.

Freeze-Thaw Stability Analysis of the High-Ice Content Soil-Rock Cutting Slope: A Case Study in Oroqen Autonomous Banner, North China

National Highway 332 (referred to as line 332) is the most convenient way for the forest areas (Oroqen Autonomous Banner, etc.) in northern China. This area is located in the high-latitude permafrost regions of the Daxing’anling Mountains. The section of line 332 from Ali River to Kubuchun Forest Farm is 116 km long, and the permafrost section is 7.45 km. Part of the section, K105+700-K105+800, is a road cutting slope with high ice content, and it is also our research object. The slope to be studied is difficult to construct and has high landslide risk, so we arranged thirty-five temperature sensors, four moisture sensors, and eighteen landmarks on the slope to grasp the dynamic changes of the slope under freeze-thaw conditions. After collecting the continuous data of temperature, moisture, settlement, and deformation of the slope, we found that the slope was undergoing freeze-thaw cycles, and the shallow slippage of the slope reached 6.811 cm in 2019. Besides, the drilled core samples were tested in the laboratory and relevant parameters were obtained. Then, the slope stability was numerically simulated in ABAQUS numerical simulation software. After two hundred freeze-thaw cycles, the slope safety factor reached 0.997, indicating that the slope was in a state of extreme equilibrium, so the potential freeze-thaw disasters must be considered during road operation, and higher requirements for the permanent protection of slopes should also be put forward. The study can provide guidance for the design and construction of road cutting slope in the permafrost regions of the Daxing’anling Mountains.

Spillovers of Urban Road Infrastructure Investment and Operation: a Case Study Using Synthetic Control Method

This study evaluates the impacts of urban road investment and operation in China, especially the spillover effect attributable to the investment of urban road projects. Using the synthetic control method and difference-in-differences technique and taking the opening of Jiaozhou Bay Bridge and its Subsea Tunnel in China on 30 June 2011 as a natural experiment, this paper investigates the causal effect between urban road investment and its economic impacts. Results show that the project has a positive externality in terms of its contribution to the output and employment: taken the industrial relative output as outcome variable, no matter whether the covariates are controlled or not, the parameters of the interactive terms are positive; taken the industrial relative employment rate as outcome variable, the gap between the treated unit and its counterpart indicates a direct program effect for the treated city as well as a spillover effect across the cities within the sample province. Furthermore, the permutation test ascertains that the probability of achieving a spillover effect as large as the treated city is around 5.88 per cent. Overall, the investment and operation of urban road transportation infrastructure has a noticeable spillover effect. Our results are robust across a series of placebo tests.

Freeway traffic flow cellular automata model based on mean velocity feedback

Making full use of real-time feedback traffic information to guide road traffic is one of the hot spots in the field of intelligent transportation system, which has practical significance for improving travel efficiency and reducing congestion. This paper proposes a new average speed feedback strategy based on real-time information, and uses it to improve the MCD model. The fundamental diagram, space–time diagram and flow interruption effect diagram obtained by simulation show that the results are consistent with the three-phase flow theory. It is found that in the free flow phase, the mean velocity feedback enables vehicles to adjust the velocity, accelerate the dissipation of the deceleration wave and maintain the stability of the traffic flow. In contrast, in the synchronized flow phase, the mean velocity feedback strategy keeps the traffic flow constant, reduces the velocity disturbance caused by the drivers’ own factors and improves the road operation efficiency.

RIOMS: An intelligent system for operation and maintenance of urban roads using spatio-temporal data in smart cities

With the construction of smart cities entering a new phase, it is necessary to broaden the requirements of traditional roads to provide efficient operation and maintenance (O&M) services. Existing road infrastructure systems fail to meet intelligent functional O&M requirements since they do not incorporate a unified method to organize and integrate road life-cycle spatio-temporal data. Capitalizing on the developments in AEC (Architecture, Engineering & Construction) and IS fields, this paper proposes a solution (ICT Artifact) for achieving urban road intelligent O&M following the Design Science Research (DSR) framework. The main contributions of this paper are: (1) proposed method for organizing, collecting and fusing spatio-temporal data of the road’s entire life cycle, based on extended COBie standard to facilitate the linking and interoperability of multi-source heterogeneous data; (2) new Road Operation and Maintenance Functional Requirements (ROMFR) from the perspective of smart cities, which provide a complete definition of road intelligent O&M functional requirements; and (3) based on ROMFR and a new generation of information technologies, the design and implementation of a system named RIOMS (Road intelligent operation and maintenance system) that supports the intelligent functional requirements. The proposed solution has been applied to Yanggao Road (Pudong New Area, Shanghai) as a case study to demonstrate its feasibility and validity. Specifically, the proposed ICT artifact has been utilized in handling typical scenarios of road O&M and its effectiveness has been assessed through survey questionnaire and smart city assessment system.

The situation of the issue of compliance of the regulatory base of Ukraine with the requirements of current legislation and the need for constant revision of the requirements for ensuring the reliability and safety of construction sites in the relevant regulations. It is determined that the development of science in the construction industry of Ukraine significantly depends on the creation of conditions for practical and mobile application of innovative technical solutions that require scientific substantiation in assessing the reliability and safety of construction sites. The issue of conducting scientific and technical support of construction sites at different stages of the life cycle is considered. The need to give a new status to the existing procedures for assessing the compliance of innovative technical solutions for their widespread implementation, which will help ensure scientific and technological progress in the construction industry of Ukraine as a whole. Problem Statement. Science has always been an important factor and prerequisite for the development of education, culture, and advanced training. Without the creation of scientific potential, an effective market economy simply cannot develop. Modern science is not only the main form of knowledge of the laws of nature and their use for the benefit of society, but also the most important tool of every person. It is established that the level of development of science and technology is a determining factor in the progress of society, improving the welfare of citizens, their spiritual and intellectual growth. Accordingly, the state should support scientific and scientific-technical activities as a source of economic growth and stimulate the use of the achievements of domestic and world science and technology to meet social, economic, cultural and other needs. Purpose. Defining the basic methodological principles of construction in modern conditions of scientific activity aimed at ensuring the reliability and safety of construction sites. Materials and methods. The importance of scientific and technical support is manifested not only at the stage of design, construction and operation of roads, but also during the monitoring of roads and man-made structures, monitoring their residual life, timely prevention of accidents and emergencies in the operation of existing roads. New construction, reconstruction, repair and operation of roads are always based on scientific and technical achievements and are based on an updated regulatory framework. At the same time, many urgent scientific and technical issues are solved in the process of experimental construction. Results. It is shown that scientific and technical support at the present stage is the main source of new experience, which should be further implemented in the relevant regulations. The necessity of carrying out scientific and technical support by scientific organizations, which are at the same time developers of relevant normative acts and normative documents, is substantiated. The experience of the «Shulgin State Road Research Institute State Enterprise» («DerzhdorNDI» SE) on solving problems of scientific activity development is given. Conclusions.

Application of GNSS Interferometric Reflectometry for the Estimation of Lake Ice Thickness

Lake ice thickness is a sensitive indicator of climate change largely through its dependency on near-surface air temperature and on-ice snow mass (depth and density). Monitoring of the seasonal variations and trends in ice thickness is also important for the operation of winter ice roads that northern communities rely on for the movement of goods as well as for cultural and leisure activities (e.g., snowmobiling). Therefore, consistent measurements of ice thickness over lakes is important; however, field measurements tend to be sparse in both space and time in many northern countries. Here, we present an application of L-band frequency Global Navigation Satellite System (GNSS) Interferometric Reflectometry (GNSS-IR) for the estimation of lake ice thickness. The proof of concept is demonstrated through the analysis of Signal-to-Noise Ratio (SNR) time series extracted from Global Positioning System (GPS) constellation L1 band raw data acquired between 8 and 22 March (2017 and 2019) at 14 lake ice sites located in the Northwest Territories, Canada. Dominant frequencies are extracted using Least Squares Harmonic Estimation (LS-HE) for the retrieval of ice thickness. Estimates compare favorably with in-situ measurements (mean absolute error = 0.05 m, mean bias error = −0.01 m, and root mean square error = 0.07 m). These results point to the potential of GPS/GNSS-IR as a complementary tool to traditional field measurements for obtaining consistent ice thickness estimates at many lake locations, given the relatively low cost of GNSS antennas/receivers.

Problematic aspects of administrative liability for violation of rules of road traffic

The article explores the issue of administrative liability for pedestrian traffic violations. It has been found that road safety issues are of concern to everyone, as we are all road users, whether drivers, passengers or pedestrians. According to the World Health Organization, the number of road traffic fatalities is extremely high and is set at around 1.25 million per year, which is unacceptable. Moreover, most of all deaths are in middle- and low-income countries, including Ukraine. It is argued that, at present, the rules of the Code of Administrative Offenses relating to measures of liability for pedestrian traffic violations are essentially dead, which is explained by the use of only a preventive measure and a rather low amount of penalties for such offenses. Administrative responsibility in the field of security is the responsibility of drivers of vehicles or other road users, including officials who are authorized to ensure the safe operation of roads and road structures, transport, operation of transport and roads, for violations of express traffic rules in the application to the perpetrators of administrative penalties in accordance with the grounds and in the manner prescribed by the rules of administrative law This all contributes to the spread of mass offenses in the industry by the efforts of legislators to remedy this situation by amending the relevant Code of Conduct in order to increase accountability and thereby reduce pedestrians' attempts to take similar actions. It is emphasized that as of 2020, a mechanism for the effectiveness of administrative liability for violation of traffic rules by pedestrians has been worked out, in the form of a draft Law on Increasing Administrative Liability in this Field for such road users – as pedestrians. Keywords: administrative responsibility, administrative liability for traffic violations, pedestrian, traffic, traffic accident
