The Metropolitan Transportation Center (MTC) is an operational unit of the Michigan Department of Transportation (MDOT). The MTC is the focal point of Michigan's leadership role in the Intelligent Vehicle-Highway Systems (IVHS) technology. The MTC serves as a traffic operations service center and an IVHS test facility. The MTC facility now under construction and the functions to be performed within the MTC will be described. The infrastructure being developed to expand the existing traffic management in the Detroit Metropolitan area and the test-bed program will be described. Specific emphasis will be placed on describing the first project of the testbed in which both the public and private sectors will be able to participate in the evaluation of various surveillance technologies and in-car communications. Initial efforts will address the "low end" users community by testing multiple incident detection and management techniques. The information learned will then be conveyed to the vehicles through several communications approaches, which also will be evaluated.

The problems of using existing automatic vehicle identification (AVI) systems for detection of vehicles on the busy city roads arise because physical barriers between lanes in the city toll sites are not desirable, while the traffic does not always comply with the lane disciplines. A new AVI system is described in this paper using the randomised time division multiplexing (TDM) technique for detecting several vehicles simultaneously entering the detection zone. Laboratory experiments carried out for up to 8 identification tags at the same time showed that all replies were detected for 900 interrogations. The collision of replying signals did not occur. The high speed transmission of serial data has, however, an error rate of 3 % - 7 %. Under the laboratory conditions, the detection errors were eliminated simply by allowing the tags to reply twice.

The paper will include a brief overview of the Pathfinder system which has been installed in Los Angeles. The system is undergoing evaluation at this time. Some implementation experiences will be included. For example, the paper will discuss some of the reasons for the changes from the presentation of congestion information in synthesized voice to all digital voice. The Pathfinder experience with mixtures of digital and synthesized speech led to confusion, which can be avoided in other systems. The time taken for message presentation was excessive and led to a necessary reduction in the number of messages presented when the voice mode is selected by the driver. This significant limitation could alter the design of other systems which might rely on speech as a presentation mode to the driver. Also, will be included the experiences encountered in the presentation of congestion symbols on the in-vehicle map display which will allow the display to function as it was originally designed by the manufacturer. One of the problems associated with superimposing symbols on a map is that as the driver "zooms" in, the symbols move away from the road. The map scaling factors must be adjusted. The design location of the symbol needs to convey both direction and intensity of the congested link. In addition, there will be a discussion on the communications testing and installation issues. The Pathfinder base station communication system involves a phone line from the control center to a communication hut owned by the city of Los Angeles. A conduit exists from the hut which is owned by the county. This conduit is terminated in another hut which is owned by the California Highway Patrol (CHP). The communication line goes from the hut to a tower where the antenna is mounted. The tower is owned by the CHP. In addition the transmitter in the hut had to be shock mounted for earthquakes. The paper concludes with a brief status of Pathfinder and considerations used for the design of the system.

The TravTek (travel-technology) project is being developed for the entire Orlando area. This project is a partnership consisting of the Federal Highway Administration, the Florida Department of Transportation, the City of Orlando, General Motors, and the American Automobile Association. The objectives of the TravTek project are to: • Explore the feasibility of ADIS and their acceptability to drivers. • Determine whether Advanced Driver Information System (ADIS) can improve utilization of the highway system, increase safety, improve travel time, and reduce fuel consumption. • Gain insights into how to build the next generation of ADIS. The TravTek vehicle equipment will be installed in 100 General Motors 1992 Oldsmobile Toronados. Seventy-five or more of these automobiles will be dedicated for daily rental to travelers while the remaining vehicles will be leased to high mileage local drivers. The TravTek demonstration projects consists of three principal subsystems: • In-Vehicle System - the system in the vehicle which provides the driver with routing and other travel information. The in-vehicle system development is the responsibility of General Motors. • Traffic Management Center (TMC) - collects data concerning traffic conditions from various state and municipal agencies, including TravTek vehicles, and then transmits this information back to the car's In-Vehicle System. The TMC is the responsibility of the FHWA, Florida DOT, and the City of Orlando. • TravTek Information and Services Center (TISC) - The TravTek Information and Services Center will support day-to-day operations of the TravTek experiment. The TISC is is the responsibility of AAA.

TravTek is a joint public sector/private sector operational field test of an advanced driver information and traffic management system. The year-long project will be operational in the greater Orlando area in 1992. In addition to the demonstration of navigation and traffic management technology, a major goal of TravTek is to evaluate project objectives and answer questions about driver behavior. The data collected will be used to examine system benefits and costs in a fully deployed system. The foci of this paper are 1) the concept of TravTek as a person-machine system, 2) the process of planning a comprehensive research program and 3) an overview of the planned evaluation approaches. Although the TravTek evaluation will not be completed until after 1992, it is hoped that this status report will assist in the research planning efforts of future Intelligent Vehicle Highway System (IVHS)/Advanced Driver Information System (ADIS) demonstrations.

The first phase of the TravTek IVHS experiment will involve the use of in-vehicle Route Guidance Systems (RGS) to determine the best routes through the Greater Orlando Area. These routes will be computed in a distributive fashion based on minute-to-minute travel time updates that are provided by a central Traffic Management Center (TMC). This paper describes the most important traffic engineering aspects of the data fusion, dissemination, and in-vehicle processing of the TravTek system with the intent of demonstrating how the features of each of these steps can be modelled within the TravTek version of the INTEGRATION traffic simulation model. The simulation of these system features is initially intended to assist in developing appropriate TMC and in-vehicle unit system control settings, and to determine the sensitivity of the benefit estimates to alternate parameter settings or system configurations. The INTEGRATION simulation model will subsequently also be utilized to simulate and explore any level of market penetration traffic effects, as well as the transferability of the TravTek results to other networks and/or different demand patterns.

The effectiveness of in-vehicle navigation systems in alleviating nonrecurrent congestions is examined. Computer simulation modeling is used to assess the effectiveness of four different types of navigation systems consisting of static map, dynamic map, route guidance and advanced route guidance systems. The study is conducted for the Irvine network, Orange County, California. The results of the study shows that the performance of descriptive in-vehicle navigation systems (static map and dynamic map) is dependent on the initial network flow conditions and could lead to severe worsening of traffic condition. The prescriptive systems (route guidance and advanced route guidance) could substantially improve the traffic situation; the performance of these systems is dependent on the level of market penetration, i.e. the fraction of drivers equipped with the navigation system. The appropriate level for the Irvine network is shown to be 30% or more.

Autonomous car navigation systems have been on the market since the mid-1980s. To date these systems have seen limited market acceptability due to high cost and lack of adequate map data bases and roadway infrastructure to make navigation systems more useful to the consumer. Today, Japan, the US, and Europe all have programs which are beginning to address making our highways more intelligent, specifying the infrastructure necessary for successful implementation. Many geographic areas are now being digitized and stored on CD ROM. Automakers are also now beginning to address the utility of these autonomous systems. One way to increase utility is to take advantage of the power of the personal computer to make a cost-effective car information and communication system which shares the navigation "computer", display and CD player. Some of the functions of the car information and communication system could include: operation and/or display of the automatic temperature control, audio and video entertainment center, trip computer, navigation system, cellular telephone, and car diagnostics. Certain features could be incorporated by taking advantage of the "computer" in the car. These features might include: autodialing, maintenance logs, "yellow pages" directory, paging, route determination and electronic mail. This paper will discuss a conceptual car information and communication system that is based on a highly-integrated, two chip "PC", the Intel386(TM)SL, which could utilize a PC-like Windows(TM) operating system, notebook PC memory cards and CD ROM based maps.
