The field of Road Transport Informatics (RTI) has spurred a substantial interest in the development and adaptation of a diverse range of technologies for vehicle-infrastructure communications. Candidate technologies for early implementation include FM RDS-TMC, short-range beacons and cellular mobile radio GSM. This paper reviews some of the major characteristics of these systems and debates some of the issues influencing the design and integration of communications technologies for RTI. Next, a possible integration framework which essentially acts to decouple RTI applications from communications networks is described. The aim is to facilitate end-to-end communications between any two application systems which need to communicate, regardless of the network to which each is attached. This concept leads to the notion of a virtual RTI network and is currently under investigation to determine its viability and applicability.

The Super Smart Vehicle System(SSVS) is information systems for drivers 20 - 30 years from now which are solutions to problems caused by automobiles and automobile traffic. The two year studies on the SSVS was begun in 1990 fiscal year under support by MITI. In this paper, first, present status and problems of automobiles and automobile traffic in Japan are described, and then, histories of information systems for automobiles and automobile traffic in Japan, which were efforts for the solutions, are explained. Japan has long histories in the information systems, where the CACS and the Intelligent Vehicle with machine vision were developed. The SSVS, integrating driver information systems and vehicle control systems, has been derived from a new concept of info-mobility, and the SSVS is realization of the info-mobility. The SSVS consists of 4 fields: information systems for a single vehicle, information systems for inter-vehicles, information systems for vehicle-to-road relations, and studies on vehicle-to-driver relations. Some of system candidates proposed for the SSVS are introduced.

In Canada, a national Intelligent Vehicle-Highway System (IVHS) - or Road Transport Informatics (RTI) or Advanced Telematics in Road Transport (ATRT) - program is under active development at present. To reach this stage, many parallel activities had to be pursued, particularly over the past four years. These have included research and demonstration projects on freeway traffic management systems and commercial fleet applications, state-of-the-art reviews of mobile systems technologies - and two major conferences, one on vehicle navigation and information systems, the other on automatic vehicle identification. This paper recalls some of the main events and progress made over this period and outlines current work in identifying Canadian involvement in the IVHS field. It is an update on a paper presented at the RTI/IVHS Conference of 24th ISATA (Florence, Italy, 20-24 May 1991) bringing into focus the most recent developments.

Considerable public and private resources are devoted to the collection and dissemination of real-time traffic information in the Chicago area. Such information is intended to help drivers make more informed trip decisions, yet its effect on driver behavior remains largely unexplored. This study was conducted to evaluate the effect of traffic reports on route and departure time changes. Downtown Chicago automobile commuters were surveyed during the AM peak period by giving them mail-back questionnaires. Drivers indicated whether or not they had changed their route and departure time decisions based on traffic reports. Further, drivers indicated how they perceived the traffic information system in terms of key attributes. Respondents also evaluated suggested improvements to the traffic information system. A majority (more than 60%) of drivers reported that they used traffic reports for modifying their trip decisions. Drivers perceived radio traffic reports positively in terms of information system attributes. Commuters were more likely to use traffic reports for their route changes if they perceived traffic reports to be accurate and timely, frequently listened to traffic reports, perceived their regular route as congested, knew multiple alternate routes, were male and higher income. Drivers were more likely to change departure times if they perceived traffic reports to be accurate and relevant, frequently listened to traffic reports and perceived their regular route as congested. Drivers indicated a relatively lower level of overall satisfaction with traffic reports indicating the existence of opportunities for improvement. One promising improvement is near-term prediction of traffic conditions on congested and unreliable routes (where conditions may change rapidly). This is because: • Drivers generally want to know the conditions at any given point (or link) along their route when they reach that point. • Drivers would be able to make better and more informed judgments regarding their trip decisions due to reduced uncertainty of traffic conditions. • The possibility that drivers may find traffic conditions significantly better or worse would be reduced. This would improve the credibility of radio traffic reports.

The INTEGRATION simulation model is being enhanced and applied at Queen's University, on behalf of General Motors Research Labs, as a tool to perform a dynamic traffic simulation study of the TravTek route guidance experiment in Orlando, Florida. While there were several different ways in which the INTEGRATION model itself was adapted, to be able to model the dynamic and route guidance features of the TravTek system, this paper focusses specifically on describing the associated dynamic modelling routines which needed to be modified and/or developed in order to generate the dynamic inputs to the INTEGRATION model. The objective of this paper is to describe the need and role of these supporting routines and to illustrate that the quality of the TravTek simulation study results are ultimately highly dependent on the capability of the supporting routines to properly generate the extensive dynamic input data that are required to properly utilize dynamic traffic simulation models such as INTEGRATION.

Video surveys are being used in Doncaster to provide an up-to-date inventory of the highway network and street furniture. The techniques being used are closely related to those under development for the collection of network attribute data for Advanced Transport Telematics (ATT) / Intelligent Vehicle Highway Systems (IVHS) systems, in particular for route guidance and navigation systems. The success of systems such as Autoguide, EURO-SCOUT (formerly called ALI-SCOUT), CARIN, Travelpilot and dual-mode route guidance will be critically dependent upon the quality of the data on which navigation and routeing recommendations are based. Experience, in London and Berlin in particular, has shown that the information presented to the driver throughout his journey needs to be accurate, precisely timed and in a large number of cases specifically tailored to the details of individual junction layouts. It is not possible to provide the quality of data necessary for system acceptance without detailed surveys of the roads on which guidance is to be given. Video survey techniques offer the flexibility to view road and junction layouts in a controlled office environment, minimising the need for costly re-surveying, and significantly improving data quality and consistency. The system in use in Doncaster is providing the basis of an innovative methodology in which in-vehicle computers are interfaced with navigation systems and professional video techniques. This results in the integration of the digital map base with the information required to generate the vitally important turning recommendations for the driver and the accurate data necessary for successful map-matching. The paper presents results and conclusions from Doncaster. It reviews the need for this type of accurate data, describes experiences in existing trials of ATT/IVHS systems, analyses developments in digital map creation techniques and presents the context into which the new generation of data collection methodology will be integrated.

As a basis for understanding the technical and nontechnical problems of implementing new technology, some sets of systems have been developed. The main features are the level of intervention (information - recommendation - automatic intervention - automated driving) and the communication link between roadside infrastructure and vehicle. An implementation checklist and a general implementation strategy have been derived and explained based on the discussion of problems. There is a noteworthy example demonstrating this development path: the project STORM - Stuttgart Transport Operation by Regional Management.

Accurate vehicle positioning with respect to a geographical database is fundamental to successful use of in-vehicle navigation systems. In this paper, the authors examine known distortions in the database by their effect on vehicle positioning as measured by the Certainty Factor. The results are shown graphically as a function of distance as the vehicle traverses the distorted region of the database. Three cases are examined using two vehicle positioning algorithms - one more heavily weighted with GPS than the other. A conclusion made is that the Certainty Factor concept is a valid measure for examining database distortions as well as vehicle positioning algorithms.

This paper describes a human factors simulation study of the decision making behavior of drivers attempting to avoid nonrecurring congestion by diverting to alternate routes with the aid of in-vehicle navigation systems. This study is the first phase of a two part project in which the second phase will apply the driver behavior data to a simulation model analysis of traffic flow. The object of the driver behavior experiment was to compare the effect of various experimental navigation systems on driver route diversion and alternate route selection. The experimental navigation system configurations included three map based systems with varying amounts of situation information and a non map based route guidance system. The overall study results indicated that navigation system characteristics can have a significant effect on driver diversion behavior, with better systems allowing more anticipation of traffic congestion. Subject route familiarity, commercial driving experience and gender did not significantly affect the results. Alternate route analysis tended to confirm the main route diversion results, and also showed that a majority of drivers were willing to accept alternate routes suggested by advanced navigation systems. These results were consistent over three significantly different congestion conditions. Driver age was also a factor, with old drivers being more reluctant to divert from the main freeway route. The paper describes the simulation approach and summarize results on diversion decision behavior and alternate route selection.
