The Efficient Deployment of Advanced Public Transportation Systems (EDAPTS) demonstration at California State Polytechnic University, Pomona assessed the viability of using the EDAPTS procurement, installation, verification, and validation processes in a small transit environment to reduce the cost of ownership for technology solutions. Modified Systems Engineering processes were used to deploy an Intelligent Transportation System (ITS) solution on the Cal Poly Pomona Bronco Express campus bus system. This report provides a summary of methodologies used, outcomes, findings, recommendations...

This report presents the findings of a study of commercial motor vehicle inspection and screening station practices with a focus on the use of various technologies to help address problems related to safety, security, roadway infrastructure, and air quality. A review of industry literature identified the various types of inspection and screening practices that have been and are being implemented including weight and size management, on-board equipment checking, driver-related violations and cargo monitoring, credential checking, and exhaust emissions monitoring. The review also identified...

Traffic congestion and trucking activities in the San Francisco Bay Area are increasing due to the rapid population growth and economic expansion. It is imperative to explore transportation alternatives, and the Bay Area Rapid Transit (BART) system, with 63 percent unused capacity on average in non-peak hours, presents such an opportunity. If BART’s service is extended to include air-freight movement, extra revenue can be generated, truck miles travelled on highways will be reduced (potentially leading to a reduced traffic congestion and pollution), and traffic safety could be improved....

This report details the design and implementation of wind tunnel tests to evaluate the aerodynamic performance of individual members of 2,3, and 4- vehicle platoons. The purpose of the tests described here is to quantify the behavior of vehicle drag, or--or more properly--drag coefficient, as a function of vehicle spacing. One-eight scale models of the 1991 GM Lumina van are used as the prototype vehicle. The design and fabrication of force balances capable of measuring drag, side force and yawing moment is described. Models are mounted above a porous ground plane surface designed to...
