Florida's Mobility Performance Measures and Experience

This paper presents an overview of mobility performance measures, descriptions of the Florida Department of Transportation’s (FDOT) reported mobility performance measures, as well as the authors’ perspectives on their usefulness and lessons learned. FDOT has taken a strong position supporting performance based programs. As such, FDOT has an extensive performance measures program covering all aspects of transportation conditions in Florida and FDOT achievements. Since the movement of people and goods is at the heart of all transportation agencies’ efforts, mobility performance measures are the key to transportation performance based processes. To adequately address mobility, its four dimensions must be addressed: quantity of travel, quality of service, accessibility, and capacity utilization. Furthermore, multiple performance measures within those four dimensions of mobility need to be developed and used to adequately describe mobility at the national, state and local levels. FDOT’s 15 primary mobility performance measures are presented and their calculation is explained. The authors and FDOT have been tracking and reporting on most of FDOT’s 15 performance measures for over ten years. The paper includes the authors’ perspectives on management’s and operating units’ use of the performance measures, administrative requirements for performance measures, and a look to the future of mobility performance measures. Further discussion is placed on the quality of service measures, delay, travel time reliability and Level of Service (LOS).
