SMART-SIGNAL: Systematic Monitoring of Arterial Road Traffic and Signals-Phase 2
Principal Investigator:
Henry Liu, Assistant Professor, Civil Engineering
Co-Investigator:
- Chen-Fu Liao, Senior Systems Engineer, Civil Engineering
Project Summary:
This project is a continuation of the principal investigator's ongoing research on the development of an arterial performance-measure system using traffic data available from existing signal systems. As part of the ongoing project, the SMART-Signals (Systematic Monitoring of Arterial Road Traffic and Signals) system is being developed and evaluated on 11 consecutive intersections of France Avenue in Hennepin County, Minnesota. Researchers will also test the SMART-Signal system on T.H.55 for 6 to 10 intersections, supported by Mn/DOT's Innovative Ideas Program.
Currently, the SMART-Signal system can simultaneously collect and archive event-based traffic signal data and automatically generate real-time performance measures such as travel time and number of stops along an arterial, and delay, queue length, and level of services for intersections. This project aims to extend SMART-Signal's capability for automatic diagnosis of operational problems and fine-tuning of signal control parameters. The ultimate goal is to develop a holistic framework that systematically measures, automatically fine-tunes, and realistically and practically models traffic flow on signalized urban arterials. A significant opportunity to achieve this project goal lies in the fact that systematic monitoring of traffic signal systems is now feasible and implementable, given the recent advances in data collection technologies as demonstrated by the SMART-Signal system.
