Traffic Information and Driver Behavior in France
The 600 Kilometer freeway network within a 30 Kilometer radius around Paris handles 40% of the overall regional traffic volume (number of vehicles). This network is now operated by a single...
Advanced Highway Control on the Central Artery
The Boston Central Artery/Tunnel project involves highways 190 and 193, in downtown Boston, placing underground 7 miles of four to eight lane tunnels. The project, with 37 lane-miles underground,...
Metering Strategies Applied to Signalized Networks
This paper describes the development and adaptation of ramp metering strategies for use in signalized networks. The strategies were developed in simulation environment using the micro-simulation...
Neural Networks in Freeway Control
Hierarchical control strategies have been proposed for freeway optimum control since the 1960's. Multi-layer hierarchical control optimizes system performance to determine a nominal metering...
Cost-Benefit Analysis on Application of AVI Technologies to Toll Services
A preliminary evaluation framework is developed for cost-benefit analysis on application of Automatic Vehicle Identification (AVI) technologies to highway toll services . The AVI technologies...
IVHS-Organizational Structure and Staffing
Continuing technology advances in IVHS present challenges that many states are unable to meet with their current staffs. Only a few states have recognized the need to plan the need to...
Optimal Strategy Within a Traffic Control Center
This paper describes part of a new Central Traffic Control System (CTCS), implemented in several sites in Europe, and recently in Haifa, Israel. The CTCS effected in Haifa contains enhanced...
A Simulation and Data Management Environment for Off-Line Testing of IVHS Technologies and Strategies
CA is engaged in a rapidly expanding statewide effort to test and deploy advanced traffic management and traveller information systems to mitigate congestion and increase mobility. To...
European Consensus Formation and Standardisation in the Area of Road Transport and Traffic Telematics
In Europe ATT-implementation projects are run both by PROMETHEUS (EUREKA) and DRIVE (Commission of the European Communities). Many of these projects are urban and inter-urban field trials...
Strategic Updating of Autonomous Route Guidance Systems for Air Quality Management
The work in this paper stems from applied research which is implemented as part of the QUARET project. QUARET is a major initiative by four European Community cities. Athens, Birmingham,...
An Integrated Route Assignment and Traffic Simulation System with a Massively Parallel Computing Architecture
This research presents two critical issues in the development of an integrated route assignment and traffic simulation system of ATMS-ATIS applications. The first issue addresses the conceptual...
An Example of Quantitative Evaluation of AVCS Safety
A method has been devised for expressing in absolute terms the effect on safety of various features in the design of an AVCS system. It depends on gathering data from different sources...
Hydrologic Runoff Models for the Arid Southwest United States
Recently, hydrologic study criteria manuals (or hydrology manuals) were prepared for the arid southwest regions of Clark County (Las Vegas vicinity, Nevada), Maricopa County (Phoenix vicinity,...
