This project presents a signal controller algorithm to capitalize on the extended information provided by wide-area detection at isolated intersections. Using computer simulation, different control strategies are evaluated and the performance of the proposed wide-area detection system with...

This study evaluates the performance and effectiveness of the Smart Traveler Advanced Traveler Information System (ATIS). The project is designed as a field operational test of three different media approaches for providing traveler information: fully automated telephone systems, automated...

This study evaluates the performance of radio links and networks to support communication with Automatic Vehicle Control Systems (AVCS). It addresses both vehicle-to-vehicle communication and roadside-to-vehicle communication. The report contributes to the modelling of short range...

The research reported in this document uses Total Factor Productivity (TFP) techniques, with which we develop measures of productivity performance of public transit systems of varying sizes and locations, and use this baseline to examine the potential contribution of alternative ITS...

This report identifies opportunities to improve transit performance using Advanced Public Transportation System (APTS) Technologies, assesses transit operator viewpoints on and experiences with APTS technologies, and proposes how current adoption and utilization practices might be improved so...

This project develops the environment for using the ATMIS simulation software developed under previous PATH projects (MOUs 39, 84, and 170) for real-time traffic simulation and scenario analysis with feedback from the real urban network. keywords: traffic simulation, databases, object-relation...

This report presents two performance enhancement lateral control designs for single unit heavy vehicles. It is shown that robust performance can be achieved using the techniques on a feedback linearized system.
