ABSTRACT 1 Connected Vehicle Program applications are being developed by researchers in the United States 2 and worldwide in an attempt to leverage data-packets transmitted and received through vehicle-3 to-vehicle and vehicle-to-infrastructure communication. The majority of these application 4 evaluations do not conform to J2735 messaging standards set forth by the Society of Automotive 5 Engineers. Consequently, this paper develops an enhanced version of the enhanced Traffic 6 Experimental Analytical Simulation (eTEXAS) tool that runs on a server and provides XML-7 based message sets that conform to current Connected Vehicle standards. An eco-speed control 8 algorithm that was developed earlier is integrated with the eTEXAS platform to receive signal 9 timing and phasing data through infrastructure-to-vehicle and vehicle-to-vehicle communication. 10 The application uses this information to optimize vehicle trajectories so as to reduce their fuel 11 consumption levels while proceeding through the intersection. The platform was tested in a cloud 12 environment and produced a 5.5 percent reduction in the total intersection fuel consumption level 13 and a 9 percent increase in the average vehicle speed on a sample intersection. The results also 14 showed that latency correction is critical in designing and implementing connected vehicle 15 applications. 16 17 TRB 2014 Annual Meeting Paper revised from original submittal.
