We have completed the construction of a system which automatically provides drivers with information on traffic congestion, traffic accidents, travel time, etc. In this system, traffic information on major ordinary roads and expressways within Osaka Prefecture is divided into 10 categories with an area number assigned to each category and information corresponding to each specified area is provided on a real-time basis by online processing in the form of a map or human voice through the medium of facsimile or telephone, respectively. The traffic information to be provided is updated every 5 minutes. For information provision by facsimile, a maximum of three A4 pages are used with traffic information in the form of text on the first page and in the form of map on the second page; graphic-pattern information manually input to and read from the input fax machine is provided on the third page. For information provision by telephone, information in a written form is first converted into a spoken form and then into sounds by speech synthesis. This paper describes the configuration, functions, and operation of this system and how it is being utilized by drivers.<>

The focus of this paper is part of an ongoing research project regarding the driver's dynamic route choice/switching behavior interacting with ADIS. The major topic investigated in this paper is a preliminary study to understand the suitability of various display patterns of ADIS for native drivers in Taiwan. The effort is performed through controlled laboratory experiments from which participants' behavior are recorded and analyzed. Display patterns used in the experiment are selected representative systems available with some modifications. A preliminary designed display system is examined.<>

The LLAMD Euro-Project (London, Lyon, Amsterdam, Munich and Dublin, with MARGOT) is a single project involving five major cities, encompassing linked field trials in a coordinated programme of research and development. The goal of the project has been to develop and demonstrate aspects of the integration of ATT systems within an integrated road transport environment (IRTE), based on the field trials in the five cities. One common theme of LLAMD is Advanced Travel Information Systems (ATIS). Each of the cities includes the development of one or more aspects of ATIS in its workplan. A second major theme is the development and implementation of systems for public transport, parking and park-and-ride information. Other key elements of the project include advanced traffic control, both urban and regional, and road safety aspects. The focus of the many ATT applications within the LLAMD group is the work on integration of applications into a single transport environment. This paper presents preliminary results of the field trials conducted in the LLAMD Euro-Project and discusses the potential for further development.<>

RHAPIT (Rhein/Main Area Project for Integrated Traffic Management) is an initiative of the German federal state of Hessen. The Commission of the EU supports this three year project within the framework of the research and development program, ATT (advanced transport telematics). RHAPIT is intended to be a component of an integrated traffic management in the Rhein/Main area. The aim of the field trial is thus to determine which kind of contribution the guidance and information system SOCRATES (System Of Cellular RAdio for Traffic Efficiency and Safety) can make to an integrated traffic management. The Rhein/Main area is one of the several European test areas where such systems are tested and evaluated in terms of their applicability. The area was chosen due to the fact that the existing collective traffic control systems and the extensive traffic database offers ideal conditions for such a field trial.<>

This paper describes a new method that employs a proximity sensor to detect a frontal collision by which the reliability of the whole automotive air bag system is expected to be greatly improved. To build the highly accurate and highly reliable systems, we must consider the following problems: 1) the air bag system can detect accurately whether the automobile collides to an obstacle; 2) the system can judge quantitatively whether the air bag should be triggered; and 3) when the air bag must be triggered, the system can expand the bag at the optimal timing. To solve the above problems, the following five processing blocks are prepared: 1) accurate detection of frontal collision; 2) estimation of both the acceleration and jerk from noisy measured acceleration by Luenberger observer; 3) filtering to estimate the velocity and displacement of the occupant's motion; 4) prediction of the velocity and displacement of the occupant's motion; and 5) judgement to trigger the air bag.<>

Techniques exist that make use of map information to improve the position estimate of a motor vehicle but the techniques lack a mathematical framework. The authors addresses this problem by developing a map-aided position estimation system whereby the raw position measurements are optimally translated so that they lie on the roads. The accuracy of the map-aided estimates is derived for an arbitrary positioning system with Gaussian measurement noise demonstrating significant improvements over the raw measurements. Further performance improvements are achieved through the use of a 1D Kalman filter developed to utilise the fact that all of the map-aided position estimates lie along known curves. The mathematical framework utilised by the map-aided estimator readily allows other sources of position information such as road type and road rules to be quantified and optimally incorporated into the estimation process.<>

The traffic control system was adopted on the Hanshin expressway in 1969 to maintain a smooth traffic flow and to ensure safety, comfortable and efficient transportation. Since then, the system has developed and expanded. We have installed four television cameras at a curved area on the expressway where motor vehicle accidents frequently occur, to experiment and verify whether accidents can be detected by processing the images taken by these cameras. As a result, we have found an effective method for detecting accidents or stationary vehicles. At present, we have developed a prototype system using 7 cameras at two locations for the detection. In this paper, we report on the method used and the experimental results.<>

The provision of weather, road and traffic information to drivers via an in-vehicle system has potential benefits for both journey efficiency and traffic safety. However, the successful implementation of such systems relies on the ability of drivers to assimilate, retain and act upon the information received. A road-based experiment investigated the ability of drivers to assimilate and retain visually-displayed travel and traffic messages whilst driving on a busy UK motorway. Subjects were presented with messages and, either 1, 2 or 3 minutes after each message, were asked a simple question about the displayed information. Their eye glance behaviour was logged, and a post-drive questionnaire administered. It was found that retention performance was affected by the length of message and the retention interval, while eye glance behaviour changed with the type of message. The findings have been used to indicate acceptable message lengths and formats for in-vehicle information, and also to provide an indication of when messages should be displayed in relation to motorway traffic and weather events.<>
