Project Summary:
Despite recent developments in real-time measurement of freeway performance using routinely available loop detector data, no similar approaches exist for monitoring the performance of urban arterial street networks. This project aims to fill in that gap by developing a real-time online performance monitoring system for arterial streets. The arterial performance data will also be archived and made available to various stakeholders for operations, planning, research, and traveler information systems, similar to the way freeway performance data are used. In this project, data availability and requirements from existing signal systems will be analyzed, and algorithms for the estimation and prediction of real-time arterial travel time and speed will be developed depending on data resolution. The project has two distinct phases: the first will focus on the data from the existing system only, without additional field instrumentation; the second will attempt to obtain higher resolution data through the installation of additional field instrumentation.
