This paper presents a method for integrating the operation of the automatic vehicle identification (AVI) system and the camera enforcement system on a multi-lane road. A downward looking wide angle camera is used to detect the presence of vehicles inside a designated detection zone of the AVI system, as well as positioning, counting and classifying the vehicles by their sizes. This information is correlated with the information received by the AVI system to command the enforcement camera system. The prototype system is tested on a 60:1 scale model road and model cars. Some preliminary results are described.<>

Fires in road tunnels are potentially hazardous. In addition to the conventional fire detection methods, new detection methods using image processing technology with infrared or color cameras have been reported. This article points out the problems associated with conventional fire detectors, and reviews some of the new detection methods. In particular, a new image processing method which compares two histograms with various shades of gray level, obtained from video images of normal traffic flow and those of fires, is proposed for fire detection.<>

This paper introduces an application of a traffic flow simulator in alleviating traffic congestion by Nissan Motor. The traffic congestion was induced by driver behavior. With the traffic flow simulator, the traffic signal timing was reviewed to suppress bypass traffic. After the traffic signal timing change, the drivers route choice changed and traffic congestion was alleviated.<>

The normally closed and normally open types are presented as a block control system configuration method and the properties of the two types are clarified logically. It is shown that signal processing of these two types are utilized as a configuration method of the airplane surface movement guidance and control system which the authors developed. Green signal lights have two roles for airplanes in this system, one is a center line to indicate the taxing line and the other is permission to go forward. Because the green lights behind the airplane finish the role of centerline and should be turned off immediately, each block section is subdivided into a shorter block section.<>

This paper is concerned with preview lateral control of an automated vehicle with a machine vision system. The lateral control is found with road edges captured by the machine vision so as to drive a vehicle along a road. The road edges are expressed in the machine vision system as two series of sampled points, and the optimal path is designed with the series of the sampled points, which enables the vehicle to drive safely and comfortably. Experiments with an automated guided vehicle (AGV) have been conducted, where the control period is about 0.5 sec and the vehicle drives at 0.3 m/sec. The results show the feasibility of the algorithm.<>

A concept of a vehicle-to-vehicle communication and ranging system, which was called boomerang transmission system, was first proposed by Mizui, Uchida, and Nakagawa (1993). By exploiting the spread-spectrum technique, the system was capable of transmitting data and measuring the range between two vehicles simultaneously, and its theoretical validity was proved using a computer simulation. In this study, a laboratory-scale prototype system was developed to confirm the workability of the concept on real electrical circuits and the capabilities of data transmission and ranging under interference signals were evaluated.<>

The shortest path problem is one of the most fundamental problems applicable in various fields, and has close relation to route navigation systems. This paper surveys algorithms for the two-terminal shortest path problem and proposes bidirectional A* algorithm based on a new approach. This algorithm is suitable for finding not only the shortest route but also better routes. The efficiency and the property of these algorithms are discussed through experiments applying them to an actual road network.<>
