A great deal of research has been conducted on Central Florida toll roads to better understand the characteristics of the tolling operation. In this paper, the use of the toll plaza queuing model SHAKER will be calibrated to replicate real life toll facility traffic conditions. SHAKER is a deterministic queuing model based on classical physics equations that determines a plaza’s maximum hourly throughput by assigning vehicles to lanes based on one of the following lane conditions: the shortest queue, the least amount of vehicles, the lane that provides the required service but minimizes the waiting-time-in-the-queue, or the lane with the fastest moving queue. An extensive study on the Florida’s Turnpike Enterprise network is conducted to determine the parameters affecting toll lane capacities. Data was collected and extracted on different toll locations, configurations, and pricing. Collected data includes traffic characteristics, vehicle characteristics, and toll plaza characteristics. From this data, periods of constant queuing were pinpointed and from those periods, factors such as demand, throughput, service-time, etc. were extracted. Using the extracted parameters, SHAKER was then calibrated and validated to estimate the capacity of four different toll plazas along the Florida Turnpike Network.
