Online Dynamic Pricing of HOT Lanes Based on Corridor Simulation of Short-Term Future Traffic Conditions

A flexible simulation framework was designed for the Ministry of Transportation of Ontario to facilitate the evaluation of High-Occupancy/Toll (HOT) lanes. This framework implements dynamic HOT lane pricing based on the simulation of short-term future traffic conditions in both the HOT lane and the adjacent general-purpose lanes. The pricing algorithm attempts to simultaneously maximize utilization of the HOT lane and maintain a specified minimum average speed. The framework is oriented to on-line operation although self-learning functionality maintains a pricing “look-up” table for back-up or standalone use. Dual, interconnected simulation instances in the AIMSUN environment maintain a reference traffic state and evaluate alternative toll-rate strategies for the next time interval. Critical elements of the framework, including the simulation environment and the pricing algorithm, were implemented and tested in the context of a hypothetical conversion of existing High-Occupancy Vehicle (HOV) lanes to HOT lanes in three corridors in the Greater Toronto Area. Results observed for this initial implementation of the framework were encouraging, given a constrained and complex environment, although there is headroom for further enhancement.
