TL;DR: Past and current efforts of General Motors in the development of the technology and the encouragement of national cooperative programs to promote the use of electronics, commuications, computers, controls, sensors and actuators applied to ground transportation are described.
Abstract: This paper describes past and current efforts of General Motors in the development of the technology and the encouragement of national cooperative programs to promote the use of electronics, commuications, computers, controls, sensors and actuators applied to ground transportation. These technological advancements are called intelligent vehicle/highway systems (IVHS). Examples of these range from presently available advanced traffic management systems to automated highways. Work by GM include the following: research on the development of a mathematical foundation for the description and understanding of vehicular traffic on roadways; automated highways; highway communications systems (Highway-to-car Communication System - HY-COM; Driver Aid Information and Routing - DAIR, etc.); traffic engineering (Traffic Pacer; Traffic Funnel); transportation systems (automated highway; automated vehicle control; intelligent vehicle/intelligent highway systems); motorist information services (a number of active programs by GM and others); advanced vehicle controls (Highway Driver's Assistant, etc.). It is noted that the future of advanced highways and advanced vehicles is through joint effort by the public/private sector involving government and industry, universities and other interests.

Journal ArticleDOI
TL;DR: A system of autonomous vehicles with vehicle- to- vehicle communication called a soft-linked vehicle system, which has autonomous navigation functions based on dead reckoning, and vehicle-to-vehicle communication for soft-linking.
Abstract: In this paper, a system of autonomous vehicles with vehicle- to- vehicle communication called a soft-linked vehicle system, is described. Each vehicle has autonomous navigation functions based on dead reckoning, and vehicle-to-vehicle communication for soft-linking. The vehicles may be driven with constant small gaps using the vehicle-to-vehicle communication, without hardware couplers or may run independently. IN JAPANESE

TL;DR: In this paper, the authors present the results of extensive reflection on the interest and feasibility of short range microwave links for road traffic informatics and examine the adequacy of the links with regard to different criteria like the required range and directivity, the sensitivity to propagation disturbances, the requirements in matter of safety and of vehicle positioning.
Abstract: The object of this paper is to present the results of extensive reflection on the interest and feasibility of short range microwave links for road traffic informatics. After a short presentation of the main electronic aids which have been considered, the authors examine the adequacy of the links with regard to different criteria like the required range and directivity, the sensitivity to propagation disturbances, the requirements in matter of safety and of vehicle positioning. With some expectations, the aids involving road-vehicle links are relatively easy to implement, the aids based on vehicle to vehicle communication raise more difficulties, and except for anticollision aids and intelligent cruise control along a lane, their perspectives of development are very low even in a long future.

TL;DR: In this paper, the authors describe the Advanced Traffic Management Systems (ATMS) element of Intelligent Vehicle-Highway Systems (IVHS) and discuss the benefits that might be achieved from the required investment.
Abstract: This paper describes the Advanced Traffic Management Systems (ATMS) element of Intelligent Vehicle-Highway Systems (IVHS). The discussion includes a review of the setting or background in which IVHS/ATMS is being considered; a description of ATMS and its role in the IVHS program; observations on the state of the art and the state of the practice; a scenario for broad scale deployment of the technology; and the benefits that might be achieved from the required investment.
