Abstract:

The objective of this project is to develop effective variable speed limit (VSL) control algorithms to minimize the total travel time on I-285 study corridor. The study corridor is Eastbound/Southbound I-285 between GA 400 and I-20. Using a stochastic simulation-based optimization framework that combines microsimulation model GTsim and a genetic algorithm-based optimization module, we determine the optimal parameter values of a combined variable speed limit and ramp metering (VSL-RM) system that minimizes total vehicle travel time. The total travel time is reduced by 8% compared to no control.
