    Publication Year: 1994
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (54 KB)

    Summary form only given. Digital map databases are considered to be the most important components of land-based navigation and guidance systems. Even when no maps are presented to the users, they are needed for spatial data processing in land-based navigation and guidance systems. Road data coordinates along with road attributes constitute these databases. The size of these databases depend on the... View full abstract»

    Publication Year: 1994
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (52 KB)

    Summary form only given. Many applications of navigation and guidance systems require the selection of best routes for their operations. A best route is what a navigation and guidance system uses for providing route guidance instructions using navigation sensors. The definition of best route may be different from one application to another. In some applications a best route may be the fastest rout... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (41 KB)

    Summary form only given. A significant effect of the progress being made in the development and implementation of IVHS technologies is the new perception of the vehicle and highway as a single transportation system. As this has not been the traditional approach, there are very few established links between the automotive manufacturers and the infrastructure owners and operators. This paper explore...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (204 KB)

    Incidents occurring on a highway decrease the number of lanes available to the through traffic, and cause congested situations, big delays, excess energy consumption and high air pollution. Non-recurring congestion becomes more pronounced during peak hour traffic. The main objective of this paper is to simulate the incident restoration operations and analyse their effects on the traffic flow in te... View full abstract»

    The trajectory control of a vehicle travelling along a motorway requires the acquisition of the lateral distance; such a datum is of paramount importance to improve the active safety for preventing accidents. To acquire this datum a reliable recognition of the road boundary has to be guaranteed. We demonstrate that by a mechanical modification of the actual cat-eyes, a highly reliable reference li...

    At higher levels of demand, the flow of traffic on motorways can become unstable with flow breakdowns and an increase in accident risk. Improvements in capacity and stability may be achieved by modifying behaviour or control, and this process is the target of research into preventative IVHS measures. However, to understand the effects it is necessary to develop and use appropriate microscopic simu... View full abstract»

    To avoid rear-end collision with the preceding vehicles on the road, we need the information of collision potentiality. It is decided primarily by the relative locations and velocities between vehicles and their absolute locations on the road lanes. We classify the recognition objects in the road scene into road lanes and vehicles for the goal of collision avoidance. We propose the consistent road... View full abstract»

    Distinction between user optimum and system optimum is a well-known phenomenon in traffic modeling. Although the difference between the two optima in real situations is usually not very large, the achievement of system optimum has been a problem to traffic authorities who do not have absolute control of traffic. With the advent of intelligent vehicle-highway systems (IVHS) technologies, economic i... View full abstract»
