In Japan, the navigation system based on digital maps came into practical use in 1987 as a predecessor to onboard information equipment. Since then, the advancement of electronic technology has successively produced similar new equipment. This paper describes the current status of in-vehicle navigation systems and predicts their future in relation to the automotive information society.<>

Navigable digital map databases have long been recognized as a key element in a wide variety of applications in IVHS and related fields, ranging from in-vehicle navigation to demographic analysis and business planning. The traditional emphasis of navigable digital map database development in the US has been on in-vehicle route guidance products, among the earliest of the major IVHS applications to reach the market. As route guidance products start to reach a broad marketplace, and as other applications begin to get serious attention, there are several notable trends in the continuing development and management of navigable map databases in the US. This paper discusses some of these trends, including issues in database packaging, the need for a national field organization to maintain database currency and accuracy, data storage and retrieval, the emergence of new applications, and US government programs for data creation and transfer.<>

The aim of this paper is to give a broad oven view of the construction of technology scenarios of an IRTE (integrated road transport environment) to enable socio-economic evaluation of the impact of VNIS technology in the transport sector. The necessary factors are identified and discussed, they include: economic development, traffic forecast, objectives and constraints, functional RTI scenario, control strategies, implementation phases, and market penetration. Examples are given based on the experience from the Gothenburg region.<>

The goal of an advanced traffic management system (ATMS) is to efficiently manage existing transportation resources in response to dynamic traffic conditions. The utility of an ATMS will greatly depend upon its ability to adaptively respond to traffic patterns and permutations. The application of knowledge-based systems and neural networks provides an ATMS with the technology required to control traffic in an intelligent manner. The volume of traffic combined with the number of streets and intersections an operator control station must monitor clearly dictates the need for computer support. Integrating these technologies with existing transportation methodologies produces a semi-autonomous system capable of reducing operator workloads while maintaining high levels of safety. This paper describes an intelligent traffic management control system called TERMINUS developed to adaptively respond to real-time traffic management problems.<>

The IVHS program in the United States has made remarkable progress. By the end of the century, there will be extensive experience in the operation of advanced traffic control centers. Some classes of accidents are expected to be nearly eliminated through IVHS. Hundreds of thousands of motor vehicles will be equipped with navigation systems and be in communication with advanced traffic management centers. IVHS is expected to make significant contributions to mobility and safety. International cooperation and coordination regarding IVHS will be much farther along as the result of the World Congress program and the increasing global view reflected in the outlook of every country.<>

A driver information system implemented in Japan provides drivers with dynamic traffic information such as travel time and congested car-length on a variable-message board. This paper gives the results of a driving survey on the Metropolitan Expressway and alternative surface roads, to analyze driver responses when receiving dynamic traffic information. Based on these results, the authors examined the efficiency of the driver information system.<>

Customer location services enable travellers to conveniently specify their trip starting point, select and locate their destination, and acquire easy-to-use instructions on how to travel to their destination. Advances in hardware, software/databases, and communication systems will dramatically affect the way we travel, whether in an unfamiliar city or own home town. The traditional IVHS concepts for providing such information have concentrated on the in-vehicle systems. Today, the new technologies invite a broader spectrum of possibilities including: enhanced telephone directory services; personal digital assistants and personal computers with network link or wireless communication, and online services. Together these will create the new services, "customer location services (CLS)", to assist the traveller. This paper describes the nature of these emerging services and the technological requirements for their implementation.<>

On urban roads, vehicles continuously emit gases and through diffusion, vehicle turbulence, heat flux and by wind the emission can transfer to the upper stratosphere and to the road surroundings. There will be some pollutant that can not transfer instantaneously due to wind velocity or road canyons. For a certain time there will be some pollutant in the road surroundings. This paper formulates a stochastic model of this quantity of gas, and the concentration of expanded gases in any particular area around the road in any time period. More precisely, the paper deals with the effects of street canyons on the dispersion of pollutants from the road environment. A mathematical model has been established to figure out the real situation of pollutants in urban roads. The model consists of traffic flow, emission and dispersion models, and wind speed modeling near the road. The principal part of the model predicts the total pollutant concentration near the ground which includes direct vehicle emissions, pollutants which have not transferred and pollutants coming from the surroundings. The prediction was performed using a bivariate normal probability density function. The variables are concentration of pollutants and wind speed. The pollutant included in this model is nitrogen oxides (NO/sub x/).<>

This paper describes the development and the architecture of an intelligent assistant system which supports a management clerk in solving route planning problems. The intelligent management clerk (IMC) cooperates with a commercial route planning system which produces optimum routes for a given scheduling problem using standard heuristic algorithms. While processing the IMC adapts its knowledge to the knowledge of the end user of the system. The development of the IMC uses various methods of artificial intelligence. The design of the whole system is based on object-oriented technologies. The decisions of the IMC are taken using a rule based system.<>
