BARRIER FACTORS AFFECTING DEVELOPMENT OF INTELLIGENT TRANSPORT SYSTEM PROJECTS

This paper identifies potential barrier factors affecting effectiveness and development (ED) of ITS projects as well as criteria for measuring ED of ITS projects in Ho Chi Minh City, Vietnam. The study discovers the barrier constructs, and analyzes data using the Partial Least Squares Structural Equation Modeling method (PLS-SEM). The results provides a general and comprehensive overview of the main issues of ITS, and identifies 28 barrier factors with five main constructs affecting ED of ITS projects, namely the lack of undivided attention from the government (AG), financial constraints for ITS (FC), inadequate transport infrastructure (ITI), the over-development of urbanization (ODU), and the readiness and integration for ITS (RI). This paper fill the knowledge gap by discovering the causal relationships between barrier constructs and ED of ITS projects in Vietnam. Also it proposes several solutions for these issues, which are also a useful measurement tool for government agencies, planners, and traffic system designers to help them self-assess and make action plans now or in the near future.

Wheel Slip-based Road Surface Slipperiness Detection

Background: Faced with the high rate of traffic accidents under slippery road conditions, agencies attempt to quickly identify slippery spots on the road and drivers want to receive information on the impending dangerous slippery spot, also known as “black ice.” Methods: In this study, wheel slip, defined as the difference between both speeds of vehicular transition and wheel rotation, was used to detect road slipperiness. Three types of experiment cars were repeatedly driven on snowy and dry surfaces to obtain wheel slip data. Three approaches, including regression analysis, support vector machine (SVM), and deep learning, were explored to categorize into two states-slippery or non-slippery. Results: Results indicated that a deep learning model resulted in the best performance with accuracy of 0.972, only where sufficient data were obtained. SVM models universally showed good performance, with average accuracy of 0.965, regardless of sample size. Conclusion: The proposed models can be applied to any connected devices including digital tachographs and on-board units for cooperative ITS projects that gather wheel and transition speeds of a moving vehicle to enhance road safety in winter season though collecting followed by providing dangerous slippery spots on the road.

Possible Impacts of C-ITS on Supply-Chain Logistics System

Abstract The purpose of this research is to introduce an analysis, which is qualitative and whenever possible quantitative, on how Cooperative Intelligent Transport Systems (C-ITS) can affect a Supply-Chain Logistics System by adopting a three-level approach. Considerations are made on the role and importance of Logistics within a company, its cost structure and the strategic relevance it assumes within the Supply-Chain, while considering its evolution from a Physical Distribution Management to a Supply-Chain Management. The increasing importance of logistics requires more sophisticated solutions to reduce or optimize its costs, as well as to find new opportunities to redesign the network configuration and the value-chain. These applications require a careful evaluation method in order to assess their effective adoption. The research is based on a literature review of the most relevant European Road ITS and C-ITS projects evaluation methods and benefits. The result of the investigation is an analysis that classifies the impact of C-ITS on the structure of the Supply-Chain according to different levels. Firstly, the paper reports the different impacts of a large-scale C-ITS deployment on the Logistics cost structure of a company and more in general, on the expected costs. After that, a second level of analysis deals with a possible redesign of the Distribution Network, oriented to the optimization of transportation costs over long distances. Finally, the third step of the analysis investigates a possible impact of C-ITS on the value-chain from several perspectives within the different roles of the subjects involved in the Supply Chain.

How to Choose and When to Start Best ITS Projects That Enhance Logistic Performance?

This paper is dealing with the evolvement of operational research in logistics related to ITS projects. Basically a static model has been introduced by the authors. The model is an extended assigned method. There are more and more quasi-real-time data existing on the changing properties of real world elements and processes due to the less and less cycle time of data collecting. On the other hand volume of the data mapping the real world in more details increased significantly. Therefore ITS projects in logistic has been examined. Later on the model has been partly dynamited.

Vehicular Networking: A Survey and Tutorial on Requirements, Architectures, Challenges, Standards and Solutions

Vehicular networking has significant potential to enable diverse applications associated with traffic safety, traffic efficiency and infotainment. In this survey and tutorial paper we introduce the basic characteristics of vehicular networks, provide an overview of applications and associated requirements, along with challenges and their proposed solutions. In addition, we provide an overview of the current and past major ITS programs and projects in the USA, Japan and Europe. Moreover, vehicular networking architectures and protocol suites employed in such programs and projects in USA, Japan and Europe are discussed.

自動車におけるゴム技術の現状と展望 自動車の安全運転支援システム―動向と課題―

In recent years, ITS projects in Japan, Europe and the US have been characterized by a strong emphasis on safe driver assistance systems designed to prevent traffic accidents. As it has become clear that eradicating accidents will be impossible by means of vehicle passive safety and single-vehicle active safety efforts alone, research and development of systems for preventing accidents through road-to-vehicle cooperation and vehicle-to-vehicle cooperation have been promoted in Japan (ASV, AHS), Europe (PReVENT, SAFESPOT) and the US (VII). The key to such technologies is road-to-vehicle communications and inter-vehicle communications. On the other hand, a number of driver assistance systems have been brought to market, including lidar-based forward collision warnings, ACC, lane keeping support and drowsiness warnings, but their penetration rates in Japan are extremely low. Furthermore, one major challenge is that safe driver assistance systems based on road-to-vehicle and vehicle-to-vehicle cooperation are premised upon a high penetration rate. Finally, we introduce a system for improving driver acceptance of safe driver assistance systems based on driver monitoring and forward monitoring as well as cooperative driver assistance systems for elderly drivers, an issue now receiving attention in Japan.

Institutional Issues in Traveler Information Dissemination: Lessons Learned from the TravInfo Field Operational Test

TravInfo is a multimodal traveler information system covering the San Francisco Bay Area. The system was intended to “collect and integrate available real-time data on all modes of surface transportation and...broadly disseminate the data through an open system designed to meet the needs of Advanced Traveler Information System (ATIS) firms” (Bay Area Ad Hoc IVHS Committee, 1992). This paper documents the institutional evaluation of TravInfo, covering the period from 1992 to 1997. It is based on interviews with key project members (three-waves), review of all meeting minutes, and first-hand observation of the organization throughout the period. TravInfo's primary successes have come in developing a network of public and private professionals, who have collaborated on ITS projects in a variety of venues. Unfortunately, however, TravInfo has not accomplished most of its initial objectives, largely due to a variety of institutional problems. Though some of the problems might be attributed to bad luck. the majority may simply be endemic to the concept. That is, by developing a public/private partnership whose primary purpose is to integrate and centralize traveler information, major institutional problems are bound to occur.
