About the Webinar:
Two common means of pricing Managed Lanes (MLs) are to vary lane-usage tolls based on time of day, or to vary them dynamically based on real-time congestion measurements. Which of the two tolling options is more effective in regulating ML-usage is unclear. Large datasets on travel speeds, traffic volumes and densities will be utilized to assess the effects of the two different congestion pricing strategies on traffic conditions. Input data will come from freeway loop detectors and Automatic Vehicle Identification (AVI) readers. Both sources can provide a rich set of data that reveals lane choices made by drivers and the resulting impacts over time and space. Changing toll rates will be correlated with traffic conditions in and out of the MLs. The goal is to evaluate the impact of the two congestion pricing approaches on traffic conditions to assess if the traffic management benefits from dynamic pricing are commensurate to its more resource intensive implementation compared to variable pricing. This presentation will discuss the analysis performed of the toll transaction data of freeway PR-22 in Puerto Rico and the results of the performance measures calculated to assess and compare the service quality of the reversible express lanes and the general toll lanes.
