Abstract:This project focused on three applications of multiple data sources, or data fusion, to evaluate traffic operations on signalized arterials. The first application used a data fusion framework to evaluate its utility in predicting travel times on signalized arterials. The second application developed a framework that combined/enhanced the Automated Traffic Signal Performance Measures (ATSPM) generated through data fusion. The third project examined the use of probe vehicle data fusion for obtaining link speeds at signalized arterials by exploring the effects of market penetration rate (MPR), broadcasting frequency (BC), and aggregation level on the accuracy of the reported speeds. Results underscore the importance of BC, MPR, and aggregation levels. Importantly, varying the performance measures tended to yield different requirements in terms of probe MPR and BC.
