his report presents the findings of a comprehensive evaluation of the freeway service patrol (FSP) program on specific freeway section in the San Francisco Bay Area. The study methodology consisted of determining the savings in incident delay and other performance measures "before" and " after"...

This report presents the results of a study designed to evaluate the effectiveness of the freeway service patrols (FSP) on a section of I-10 in Los Angeles. An evaluation methodology was used to estimate incident delays based on loop detector data and probe vehicles, and derive estimates of...

This document is a reference manual for the fsp and xfsp programs. The fsp program is a software tool used to interrogate the data that was collected during the Freeway Service Patrol Evaluation Project. The purpose of the program is to perform diagnostics on the data, generate error reports,...

This paper presents a methodology to evaluate a benefit-to-cost ratio effectiveness of the Freeway Service Patrol in a freeway section in Los Angeles. The methodology addresses the process of estimating incident delay using probe vehicles and the lack of "before" data.

We present a novel, off-line approach for evaluating incident detection algorithms. Previous evaluations have focused on determining the detection rate versus false alarm rate curve -- a process which we argue is inherently fraught with difficulties. Instead, we propose a cost-benefit analysis...

The goal of this study was to provide a better understanding of the impacts of route guidance on urban arterials and networks controlled by traffic signals. Control and timing strategies to handle diverted traffic from the freeways to surface streets were developed and tested through simulation...

This report discusses the major factors which influence the benefits from transit priority. It reviews existing control strategies that have been implemented in signal controlled networks. A number of control strategies to improve transit performance are proposed along with an analysis technique...

An algorithm for real time estimation of truck traffic in multi-lane freeway is proposed. The algorithm uses data from single loop detectors-the most widely installed surveillance technology for urban freeways in the US. The algorithm works for those freeway locations that have a truck-free...

Freeway service patrol (FSP) is an incident management measure designed to assist disabled vehicles along congested freeway segments and reduce congestion through quick detection, response, and removal of accidents and other incidents on freeways. A two-year demonstration project has been...

This report describes the evaluation of the effectiveness and adequacy of cellular phones for incident detection as an alternative to infrastructure-based surveillance systems. The analysis was part of the I-880 field experiment using the California Highway Patrol's (CHP) Computer Aided Dispatch...
