Includes bibliographical references.Executive summary -- Introduction -- Data collection and management -- Computational methods -- Applications -- Summary."TRB's second Strategic Highway Research Program (SHRP 2) Report S2-L02-RR-2: Guide to Establishing Monitoring Programs for Travel Time Reliability describes how to develop and use a Travel Time Reliability Monitoring System (TTRMS). The report also explains why such a system is useful, how it helps agencies do a better job of managing network performance, and what a traffic management center (TMC) team needs to do to put a TTRMS in place."--Publisher's description.

Evaluation of a video image detection system / by Cottrell, Benjamin H.(CARDINAL)311411; Virginia.Department of Transportation.(CARDINAL)291718; Virginia Transportation Research Council.(CARDINAL)195142;
Includes bibliographical references (page 27).Final report.A video image detection system (VIDS) is an advanced wide-area traffic monitoring system that processes input from a video camera. The Autoscope VIDS coupled with an information management system was selected as the monitoring device because testing had shown it to be the most advanced system available with respect to performance, reliability, and accuracy. The purpose of this project was to evaluate the capabilities of the VIDS. The primary objective was to assess the performance of the VIDS for incident detection, and a secondary objective was to examine its capability to monitor traffic. Existing hardware was to be used for the VIDS as much as possible in order to fit the VIDS into the existing TMS Center operations and to minimize additional costs. Based on an evaluation that focused on traffic monitoring, the VIDS performed unsatisfactorily at two sites and satisfactorily at a third site. The location of the video camera relative to the monitoring site, which is critical to effective operations of the VIDS, was the major cause of the unsatisfactory performance. The primary objective was not achieved. The potential for using the Autoscope at existing camera locations in Northern Virginia is limited. Based on the performance of the Autoscope at the Woodrow Wilson Bridge, it was concluded that it is difficult to accurately return an Autoscope camera to its monitoring position after it is moved for surveillance. A dedicated camera is necessary for the VIDS. Recommendations were made for the use of the VIDS and for project planning and contract administration for future projects of this nature.Sponsored by the Virginia Department of Transportation, in cooperation with the Federal Highway Administration, under contract no. 9629-030-940. Performed by Virginia Transportation Research Council.
