ABSTRACT: The Portland region has good sensor coverage on freeways, but the arterial system is limited to snapshots of measurements from traffic studies using floating car studies and temporary traffic counts. There is a need to implement automated systems that can provide arterial travel time and performance measures for management of freight and passenger travel. This project will include a review of technological solutions for automating traffic measurement on arterials. Priority surface arterial locations for measurement will be identified, considering geographical balance and specific bottleneck locations. The task will include a case study of arterial operations on Barbur Blvd in the City of Portland. Working with the City of Portland, we will review options for using existing system detectors and CCTV cameras to gauge arterial performance. The task will also evaluate the potential to install approach delay measurement systems (specially designed loops combined with Autoscope) like those being installed by the City of Portland at the MLK & Columbia intersection. The research will validate the delay measurement and recommend locations for such systems on Barbur Blvd. The City will then install 2 or 3 systems on Barbur, which will then be evaluated. The approach delay measurement system offers promise for providing an automated way to determine approach delay at a signalized intersection. This task will further validate that system on other intersection approaches. The results will also provide the City of Portland with methods to provide meaningful performance measures for Barbur Blvd. and beyond.
