SIMULATION AND EVALUATION OF THE ORLANDO-ORANGE COUNTY EXPRESSWAY AUTHORITY (OOCEA) ELECTRONIC TOLL COLLECTION PLAZAS USING TPSIM (COPYRIGHT)

A discrete-event stochastic microscopic simulation model developed by the Transportation Systems Institute (TSI) at the University of Central Florida known as TPSIM (copyright) was validated in this study. Real-life data collected at the busiest toll plaza in the Orlando-Orange County Expressway Authority (OOCEA) system was used to validate the developed model. Statistical tests indicated that there is no significant difference at the 95% confidence level between Measures of Effectiveness obtained from the model and those collected in the real world. TPSIM (copyright) was used to quantify operational benefits gained by installing E-PASS. Sensitivity analysis of market penetration of the E-PASS system indicates that an increase in E-PASS subscription rate improves the efficiency of the toll plaza operation. For all plaza configurations simulated with the manual lanes operating over capacity, the total plaza delay can be reduced in half and average queuing delay per vehicle can be reduced by more than 90 seconds if only 10% of the users can switch from manual to Electronic Toll Collection (ETC) lanes. Sensitivity of peak hour delay to the plaza traffic demand increases more rapidly with higher traffic volumes. An increase of 20%-30% of the plaza throughput can be achieved by switching only 10% of the manual users to ETC users during the morning peak hour when the manual lanes operate over their capacities. Analysis of peak hour delay showed also that adding more dedicated ETC lanes immaturely, i.e., without an increase in the level of ETC subscription, can cause an increase in the plaza queuing delay and decrease in the total plaza throughput.
