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....
A Dynamic Modelling Framework of Real-Time Guidance Systems in General Urban Traffic Networks
There is considerable interest around the world in developing and implementing realtime driver information and/or guidance systems to reduce congestion in the urban traffic networks. However...
Routing Based on Anticipated Travel Times
The routing of drivers based on anticipated as well as instantaneous link travel times has presented route guidance system developers with an opportunity to achieve additional IVHS benefits...
Geographic Database for IVHS Management
A IVHS (Intelligent Vehicle Highway System) information management system obtains information from road sensors, city maps and event schedules, and generates information to drivers, traffic...
Computer Simulation and Disposition in Railway

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...
A Preliminary Systems-Level Evaluation of Automated Urban Freeways
Transportation planners predict that traffic congestion will increase dramatically in the future. With 63% of all congestion on urban freeways, much of it in high-density areas, traditional...
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...
CADD?Database Application for Facility Inspections
In 1989, the Sverdrup Corporation was hired to perform the Comprehensive Inspection of the Queens-Midtown and Brooklyn-Battery tunnels in New York City. From the onset of the project it...
Design of HCM Signal Timings Using Signal Expert
While computer implementations of the procedures for evaluating the operation of traffic signalized intersections are receiving widespread use, these implementations are still primarily...
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...
An Application of Expert Systems to Traffic Signal Control
Signal Control at Isolated Intersections (SCII) has been developed to emulate an adaptive controller using AI technology. It is an application of expert systems to the real-time traffic...
Bus Pre-Emption: A Real Time Control Strategy for Privatized Transit Operation
Bus pre-emption strategies are designed to provide priority to transit buses over passenger cars for urban travel. A comparative analysis of a proposed suburban bus service for regular...
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...
Error Rate Measurements of RDS-FM Transmissions Application to an RDS-Beacon
The Radio Data System is now commonly implemented on many European VHF-FM broadcasting transmitters. RDS provides for the transmission of a silent data channel on existing VHF-FM radio...
