Comparison of Traffic Signal Systems in Australia and North America
Dynamic coordinated traffic signal systems were developed in Australia in the 1970's, and are now installed in many countries. In contrast, strong interest in new generation...
Fully-Distributed Control of Signal Networks
A fully-distributed real-time control strategy is described for signalized networks. The signals make compatible, simultaneous decisions about cycle length, offset and splits, without...
Cars: A Demand-Responsive Traffic Control System
This paper presents a demand responsive traffic control system for networks based on improvements from a combination of OPAC and ACTS approaches. The system has shown clear advantages...
An Analytical Framework for Minimizing Freeway Incident Response Time
The reduction in incident delay is an important aspect of any freeway management program as it results in substantial savings to roadway users. This paper presents an integrated decision...
Optimal Ramp-Metering Control for Freeway Corridors
The paper discusses an optimal ramp-metering control model wherein a corridor is discretized into small road sections, with density as the state variable and ramp metering rates, the control...
Application of Control Theory to Regulate Traffic Flow on Periurban Ringways
Two on-ramp metering strategies are compared by a simulation study for the Boulevard Peripherique in Paris. The first one is a local strategy, based on linear feedback control theory....
Potential Freeway Capacity Effects of Advanced Vehicle Control Systems
Intelligent Vehicle/Highway Systems (IVHS) are intended to improve the productivity (capacity) and safety of the road transportation system. The PATH program has placed a stronger emphasis...
Institutional Barriers to IVHS Introduction
The introduction and application of Intelligent Vehicle/Highway Systems (IVHS) will help to mitigate the adverse safety, environmental, and economic impacts of traffic congestion on selected...
Design and Evaluation of Multi-Band Progression Schemes
Multiband is a new arterial progression scheme that has the capability to assign each directional road section with an individually volume-weighted band. The method offers to the traffic...
Advanced Software Design and Standards for Traffic Control
Improved traffic traffic management and control systems are widely reported to be cost effective investments [Neudorff 88, Kessmann 85]. However, many hardware and software obstacles have...
Traffic Control System on the Hanshin Expressway
The Hanshin Expressway Public Corporation, Osaka, Japan has been developing and operating its automated traffic control system since 1969. This paper deals with the latest version of the...
Safety of IVHS: Methods for Determination of Accident Levels for AVCS-1 Devices
This paper discusses ways in which the safety impact of Intelligent Vehicle/Highway Systems (IVHS) devices can be estimated by interpreting existing statistics. This is needed at many...
Taming the Silicon Steed?Perceptions of Risk
This paper draws from contemporary research in the psychological literature to argue that transportation engineers and decision makers should consider the issue of perceived risk when...
The Contribution of Dynamic Route Guidance and Information Systems to More Efficient Traffic Management
The environmental and traffic-related problems expected as a result of the continued increase in motorization require new solutions if our towns and cities are to survive and their attractiveness...
