Abstract
SARSA (Sutton, 1996) is applied to a simulated, traffic-light control problem (Thorpe, 1997) and its performance is compared with several, fixed control strategies. The performance of SARSA with four different representations of the current state of traffic is analyzed using two reinforcement schemes. Training on one intersection is compared to, and is as effective as training on all intersections in the environment. SARSA is shown to be better than fixed-duration light timing and four-way stops for minimizing total traffic travel time, individual vehicle travel times, and vehicle wait times. Comparisons of performance using a constant reinforcement function versus a variable reinforcement function dependent on the number of vehicles at an intersection showed that the variable reinforcement resulted in slightly improved performance for some cases. 1. Introduction A variety of traffic control strategies are being studied in real traffic networks and in simulation. The Denver Regional Co...
