The Impact of Online Transportation Services on Indonesian Urban Non-Working Trip Volume and Distribution Pattern: A Case Study in Bandung City

The development of digital technology has made it much easier for most people to access online communication through smartphones. Such a phenomenon has encouraged operators to develop an online transportation service system, which has also been growing in Indonesian urban areas. The urban community accepts the new alternative of the application-based transportation system since it offers a much more efficient way to reach transportation services. Moreover, the online transportation system also offers a much wider range of destination locations. It is believed that the creation of an application-based transportation service system will affect metropolitan areas' social and economic conditions and how urban communities’ travel. The development of this application-based transportation service would change the configuration of urban non-working trip distribution patterns, which should be understood as inputs for the urban transport development plan. This research aims to understand the impact of online transportation services on non-working trip distribution patterns in Indonesian urban areas, with Bandung City as the case study. The method used in this research is statistical descriptive, using respondents' responses to map the influenced trip generation and distribution patterns. The results show that online transportation has enabled the community to travel more easily and reach wider areas. Such changes have formed a new travel pattern that extends the destination locations to a wider peri-urban area. In the future, the government should anticipate urban fringe area land use growth, changing the region into more "urbanized-built-up" areas.

Application of an Improved A* Algorithm for the Path Analysis of Urban Multi-Type Transportation Systems

The modern urban transportation service network could be split into unrestricted and restricted networks depending on whether travelers face limitations in route selection. Along with the continuous expansion of the city, it is difficult for travelers to find a more reasonable travel solution when confronted with such a complex transportation service network, which combines both unrestricted and restricted networks, especially for the park-and-ride (P&R) travel mode. This paper addresses the issue of route analysis in modern urban transportation service systems to provide travelers with reasonable travel solutions based on multiple types of transportation services. An improved A* algorithm is proposed to address the optimal path analysis for restricted networks to provide reasonable travel solutions for public transportation trips. Furthermore, by establishing the topological relationship between restricted and unrestricted networks, this paper presented an improved A* algorithm based on hybrid networks that solves the optimal path analysis problem for P&R trips, bringing convenience to many urban travelers.

Methodology for Designing a System of Public Passenger Transport in a Functional Region

Transport, as an object of research and design, is directly influenced by other functional components of the territory, it is caused by them, but at the same time it determines them in terms of limitations and development. A comprehensive approach to the design of transport systems involves a wide range of analytical and synthetic activities. Transport and territory are interrelated, while transport is one of the main factors defining the functionality of territorial structures. The development of transport systems brings greater availability of work, services, and leisure activities. The transport solution in the territory must be directed towards the adequate satisfaction of the transport needs, which are characterized by the intensity of the transport relations in the territory, depending on the time and quality of the relocation. The article presents a methodology for the design of regional public passenger transport lines, in accordance with the principles of sustainable mobility, supporting the competitiveness of public passenger transport and the efficient use of resources. The proposed methodology presupposes an already completed and processed analytical phase of the transport planning process and includes the impact of public passenger transport on the external environment. The methodology is applicable under the conditions of designing a completely new transport service system, as well as in the process of reorganizing existing transport systems, including rail and bus transport.

Visualising Transformations of Geographical Time–Space by Transport Systems. The Case of Germany, 1990–2020

By accelerating the overcoming of space on certain relations, transport systems alter the accessibility of places and distort geographical time–space. Particularly in the case of discontinuous and tiered transport systems such as (high-speed) rail networks, effects on time–space can be highly selective and difficult to visualise. This paper compares different methods of operationalisation and visualisation of the effects of new transport systems (infrastructures and services) on time–space, and examines their strengths and weaknesses, using the example of the evolution of the German rail network between 1990 and 2020. The methods are well-known ones such as isochrones, choropleths using measures from network theory, anamorphosis (cartograms) and less-known ones as spring maps and the shrivelling model. For the examination of the readability of the methods, we present relevant properties for time–space maps. The results suggest that conventional methods are simpler to interpret, but fail to convey certain properties, while less frequently used methods may be better at incorporating the properties at the cost of being more difficult to read.

DAG-based swarm learning: a secure asynchronous learning framework for Internet of Vehicles

To provide diversified services in the intelligent transportation systems, smart vehicles will generate unprecedented amounts of data every day. Due to data security and user privacy issues, Federated Learning (FL) is considered a potential solution to ensure privacy-preserving in data sharing. However, there are still many challenges to applying the traditional synchronous FL directly in the Internet of Vehicles (IoV), such as unreliable communications and malicious attacks. In this paper, we propose a Directed Acyclic Graph (DAG) based Swarm Learning (DSL), which integrates edge computing, FL, and blockchain technologies to provide secure data sharing and model training in IoVs. To deal with the high mobility of vehicles, the dynamic vehicle association algorithm is introduced, which could optimize the connections between vehicles and road side units to improve the training efficiency. Moreover, to enhance the anti-attack property of the DSL algorithm, a malicious attack detection method is adopted, which could recognize malicious vehicles by the site confirmation rate. Furthermore, an accuracy-based reward mechanism is developed to promote vehicles to participate in the model training with honest behaviors. Finally, simulation results demonstrate that the proposed DSL algorithm could achieve better performance in terms of model accuracy, convergence rates and security compared with existing algorithms.

MODELLING THE ECONOMIC INFLUENCE OF TRANSPORT SYSTEM ON TOURISM PERFORMANCE. THE EXPERIENCE FROM LAGOS STATE, NIGERIA

Globally, travel and tourism opportunities are highly sought-after by most nations, but very few developing nations, including Nigeria, play good supporting roles to benefit from the profitable and lucrative industry. The reasons for this are not unconnected to the poor investment in tourism infrastructure, especially transport, to support tourism activities and sustain tourism performance. It is against this background that this study modeled the economic influence of the transport system on tourism performance using Nigeria’s Lagos State experience. This study is anchored on an ex-post facto research design and relies on quantitative data from the relevant ministries of the Lagos State Government. Both descriptive (charts and graphs) and inferential (multiple linear regression analysis) statistics were methods of data analysis. Major findings revealed that only the annual revenue from transport system services out of the nine (9) evaluated performance indicators showed internal consistency and a positively increasing growth pattern. Furthermore, research found that the level of transport investment has a statistically significant relationship with the performance of the tourism industry (. Meanwhile, findings also revealed that there is a statistically significant relationship between the transport system’s revenue and tourism performance (. Given these, this study affirmed that the tourism performance greatly depends on the transport system’sinvestment and revenue and concluded that the fluctuating and poor tourism performance in Lagos State, Nigeria, is a function of the transport system's economic influence. Thus, this study recommends, among others, consistent investment and improvement in the transport system, most especially the infrastructure that will support tourism activities and increase tourism revenue.

Optimizing Traffic Flow in Smart Cities: Soft GRU-Based Recurrent Neural Networks for Enhanced Congestion Prediction Using Deep Learning

Recently, different techniques have been applied to detect, predict, and reduce traffic congestion to improve the quality of transportation system services. Deep learning (DL) is becoming increasingly valuable for solving critiques. DL applications in transportation have been collected in several recently published surveys over the last few years. The existing research has discussed the cloud environment, which does not provide timely traffic forecasts, which is the cause of frequent traffic accidents. Thus, a solid understanding of the difficulties in predicting congestion is required because the transportation system varies widely between non-congested and congested states. This research develops a bi-directional recurrent neural network (BRNN) using Gated Recurrent Units (GRUs) to extract and classify traffic into congested and non-congested. This research uses a bidirectional recurrent neural network to simulate and forecast traffic congestion in smart cities (BRNN). Urban regions worldwide struggle with traffic congestion, and conventional traffic control techniques have failed miserably. This research suggests a data-driven approach employing BRNN for traffic management in smart cities, which uses real-time data from sensors and linked devices to control traffic more efficiently. The primary measures include predicting traffic metrics such as speed, weather, current, and accident probability. Congestion prediction performance has also been improved by extracting more features such as traffic, road, and weather conditions. The proposed model achieved better measures than the existing state-of-the-art methods. This research also explores an overview and analysis of several early initiatives that have shown promising results; moreover, it explores two potential future research approaches to increase the accuracy and efficiency of large-scale motion prediction.

Understanding Influencing Factors of Travel Mode Choice in Urban-Suburban Travel: A Case Study in Shanghai

After the rapid expansion of the subway system over the past two decades, some cities are preparing to build more suburban railways. The emergence of suburban railways is bound to change the choice of suburban passenger transportation. This paper studies the factors that affect the choice of travel mode at the construction stage of suburban railways, aiming to design a more rational suburban railway network and urban public transport service system. Taking Shanghai as an example, this study first surveyed revealed preference (RP) and stated preference (SP) among urban-suburban travelers. Then, we used discrete choice models (DCM) and machine learning algorithms to build a travel mode choice model based on data collection and analysis. Furthermore, the importance of each factor was analyzed, and the effects were predicted under several traffic demand management schemes. Finally, this study proposed some strategies for increasing the share of public transport. On the one hand, it is suggested that Shanghai should continue to develop suburban railways and maintain low pricing of public transport services. Considering the construction and operation costs, the government needs to provide certain subsidies to stabilize prices. On the other hand, as passengers are very sensitive to the “last mile” trips in their suburban railway travel, transport planners should strengthen the connection from and to the suburban railway stations by developing services such as shared bikes and shuttle buses. In addition, the results indicated that some traffic demand management measures can also contribute to a larger share of public transport.

Will electric car-sharing attract citizens of touristic islands? Evidence from the island of Rhodes, Greece

The introduction of shared mobility services in transportation systems has created the potential to address traffic congestion and environmental issues, which derive from passengers’ transport. Thus, shared mobility services, including electric car-sharing, can significantly assist the formation of sustainable cities. Although car-sharing systems have already been established to several cities worldwide, Greece lags in adopting these systems. The sense of ownership for the citizens is strong and there is a great tendency of using private cars. It is observed that this tendency is even higher for the citizens of touristic islands. For understanding whether electric car-sharing could attract a part of the citizens, a questionnaire survey was conducted in the island of Rhodes, Greece. A stated preference experiment is included in the questionnaire, where the citizens were asked to select among a shared electric car and their private car, in scenarios where the trip duration and cost are fluctuated. Descriptive statistical analysis and a discrete choice model were implemented for analyzing the gathered responses. Through the discrete choice model, the parameters that affect the intention of the citizens to use a shared electric car are being identified and the value of time of the citizens is being also computed. Based on the results, useful policy and market-oriented recommendations derive.
