Predetermining Performance-Based Measures for Managed Lanes

The objective of this research was to develop a multi-faceted framework to aid in operational decision-making over the life of a managed lane facility. To begin, this study reviewed the state-of-practice in operational performance management of tolled and managed lane facilities and captured the methods by which agencies are setting toll rates to manage performance. The authors found most agencies had some goals and objectives in writing. However, there is no advanced policy framework that addresses changes in the number of passengers required for free travel on a high occupancy toll (HOT) lane, which are always left to the governing body. In conducting this review many organizations from around the country were investigated for any ‘performance promises’ they might have on any of their facilities. A performance promise is where the operator of the facility indicates what changes will be made (for example not allowing high occupancy vehicle for 2 person (HOV2s) in the event some measure (for example speed) drops below a set threshold. Although many verbally expressed interest in the idea, only one had clearly defined triggers that when hit, specific actions were undertaken to ensure performance. The goals and objectives for the surveyed projects proved interesting and insightful in the development of the multi-faceted framework. Results of this state-of-practice review, in conjunction with guiding principles, performance measures and data collection elements, will be used to develop a decision framework to guide the changes in operational strategies for a facility over time.
