The system described, named CombiCom (Combined Transport Communication System), is developed from the CombiCom project, part of the EC DGXIII DRIVE II programme for Advanced Transport Telematics. The introduction of a real-time information system, together with automatic identification, which monitors the movements of load-units, could provide the signalling of deviations from a schedule and inform the traffic agents and their clients at an early stage in time. The CombiCom project realises such an information system on the corridor Rotterdam-Kijl n-Verona. By the use of automatic identification equipment, observations in real-time are made at entry and exits of the terminals and along the routes. These observations are interpreted by the system and used to signal deviations from the planned situation through an alarm function.<>

In Programs like DRIVE or PROMETHEUS different systems for advanced traffic management systems (ATMS) and advanced traveller information systems (ATIS) are developed. In order to evaluate these new systems within the traffic simulation tool PRORAD an adequate representation of the driver, his driving behaviour and his reaction to traffic messages must exist. The aim of this study is the development of such a driver model comprising the data structure and the driver's behaviour. In order to model the driver and his behaviour various techniques of artificial intelligence are used. The whole system is designed using object-oriented techniques. The driver's decision is taken by using a rule base system. Various algorithms of operation research and AI are used for the driver's route planning.<>

This paper provides a progress report on the TravInfo project-the San Francisco Bay Area Intermodal Traveler Information System- including the project organization, plan, schedule, implementation experience, and evaluation approach. The public sector will provide open-access databases for region-wide real-time traffic and public-transport information. The TravInfo Transportation Information Center (TIC) will disseminate this information through an audiotext phone system, a landline system, and a wireless data broadcast. Private sector will provide products and services that present this information to both public and private sector users. Overall, TravInfo is intended to make public transport easier and more attractive to use, and to assist in reducing and in avoiding traffic congestion. In addition, it will serve as an ATIS test bed and as a test market for determining the types of ATIS products and services that IVHS users want and are willing to pay for. TravInfo is an open partnership available to public and private sector organizations both foreign and domestic. The trial is scheduled to operate for a period of approximately two years beginning in early 1995. Successful elements of TravInfo are expected to continue in use.<>

A major cause of accidents during cornering is the excessive vehicle speed due to the driver's incorrect recognition or misjudgement of the curvature of the road, the vehicle performance and the road conditions. We are now studying a self-reliant cornering vehicle speed control system without using outside facilities along the road. This paper presents the base technology of such a system which predicts the curvature of the oncoming road based on the map information from the car navigation system which has already been installed in production vehicles in Japan.<>

This paper proposes a new method of controlling traffic flow over the road network. A diversion of traffic is carried out by maximizing the over-all network evaluation function. A new method to increase the available information based on "sensor fusion" is also proposed. Several numerical analyses are carried out and some promising results are obtained.<>

In order to implement the accuracy and detailed map database with wide area coverage, the database should be compact in size and must be created efficiently and automatically, at low cost. We developed a software system to resolve these problems. With this system, we first make an original map database by enhancing road data from the Japan Digital Road Map Association, and add other important information such as facilities and traffic restriction information. Then, according to the display scale of each map, adequate road details, background, and character information is selected and extracted from the original database. Layouts of character information are determined automatically according to the priority of each item of information and spacing between each character. In this way, a map database can be automatically generated at less than one third the size of the original database. As a result, map data of the whole area of Japan can be stored in a CD-ROM disc. This paper describes the data compression method and an automated conversion algorithm of map data into a compressed format.<>

In intelligent road traffic management systems various dynamic road traffic information is available so that the behavior of traffic flow is affected by the information. An object-oriented road traffic software simulator has been developed as a tool for studying the flow. As an application of the simulator, some examples of intelligent traffic simulation on it is introduced and their results are reported. One example is signal control on a small network compared with conventional control which minimises total delay time and the control which guarantees drivers maximum delay time. The other is the effect of parking availability information for three parking areas.<>

This study examined the effect of background scene complexity on the legibility of head-up display (HUD) presented information for automotive applications. Subjects viewed video footage following a car on an open road with low, moderate and high scene complexity. Subjects were required to track the lead vehicle and identify HUD presented targets of a specified orientation and specified changes in a HUD presented speedometer. The results indicate that: 1) HUD legibility deteriorated with increased visual complexity of the background scene; and 2) positioning the HUD on the roadway ameliorated the effect.<>
