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...

Maglev Technology: A Look at Guideway Construction and Maintenance Concerns
Magnetically levitated vehicle technology, maglev, serves as a potential solution to ever increasing transportation demands. Though interest in maglev appears to be increasing, an appropriate...

Two Approaches for Characterizing Images of Rail Surface Flaws
