Abstract:This report contains the finding of the public agency efficiency impact assessment associated with the Tampa Hillsborough Expressway Authority (THEA) Connected Vehicle Pilot Deployment (CVPD). In this report, the Texas A&M Transportation Institute (TTI) assesses how the deployment impacted stakeholders’ ability to improve their operational efficiency and situational awareness. TTI used data provided to the THEA CVPD team as well as supplemental interviews with impacted stakeholders. Because of issues associated with the deployment, TTI was only able to provide a qualitative analysis. The analysis found that the biggest impact on public agency efficiency came from the performance monitoring tool developed by the Center for Urban Transportation Research. The tool uses data collected from onboard units and roadside units to monitor the status of the deployment and provide insight into the locations and time frames where warning alerts and messages were provided to equipped vehicles. The tool allows stakeholders to monitor the operational heath of the system by monitoring the status of the field devices and providing stakeholders with performance indicators on the effectiveness of the applications. The tool allows stakeholders the ability to monitor system performance at individual intersections or on system-wide basis. Stakeholders can aggregate performance statistics over time and by individual sites. This tool provides a solid foundation for the agencies to build upon as they enter future deployment phases.
