Abstract:
Despite the well recognized fact that a proper control of traffic speed can contribute to both reduction in accidents and efficiency of highway operations, most existing speed control strategies implemented in Europe and U.S. tend to aim only at improving traffic safety. This research intends to present an on-line algorithm for variable speed limit (VSL) control at highway work zones that can take full advantage of its dynamic functions and concurrently achieve the objectives of throughput maximization as well as accident minimization.
