This report describes the results of the PATH/Caltrans-funded project Video-Base Signature Analysis and Tracking (VSAT) System, Phase 1: Verification of Concept and Preliminary Testing. The VSAT System was conceived in 1995 by Loragen Systems, of Glendale, California, as a means for non-intrusively tracking individual vehicles on freeways for data collection purposes. The concept involves the use of a computer vision methods to make simple measurements of external dimensions, points of optical demarcation, and predominant colors of each vehicle. A conventional color video camera serves as...

Transit systems have traditionally been developed independently from one another,certainly across different regional jurisdictional boundaries,however,even within the same regional jurisdictional boundary where the ramifications of this are most significantly felt.Little attention has been given to coordination,integration,or interoperability between and among systems.As a result,customer satisfaction,market share and public transit relevance has continued to decline. This report,which presents the findings from our literature review of the topic of multi-agency transit operations,...

This report documents a review of the literature of transit service integration policies. It is the initial task of a project whose objective is to understand service integration policies and practices that transit agencies have employed and the benefits such policies have brought. Studies have shown that ongoing coordination and integration of transit services can improve public transportation system connectivity and reliability, and help make transit a more attractive travel mode alternative to the car. Findings from the literature shed light on several topics, including how service...

Traffic responsive control strategies are increasingly being implemented to improve intersection performance. Critical intersection control (CIC) is using real-time traffic data to better assign green times to conflicting movements. However, the benefits of CIC have not been assessed, and existing methodologies for estimating intersection performance do not account for CIC or other traffic responsive control strategies. The effectiveness of CIC was evaluated at seven signalized intersections in the City of Los Angeles. The findings indicate that CIC generally improves traffic operations....
