Abstract:
This paper describes the use of microsimulation for transportation planning in small communities. Using new simulation tools, it is possible to simulate entire planning networks for small and medium-size, and possibly larger, communities. This leads to more realistic model results than that resulting from conventional traffic assignments that are static, ignore actuated traffic signals, and permit unrealistic volume to capacity ratios. In contrast, microsimulation models account more appropriately for the effects of traffic signals and other causes of delay. In this paper, the authors present a case study that compares an area-wide microsimulation with a conventional four step model for the Columbus, IN community. The advantages of the microsimulation approach are identified and evaluated and guidance is provided for implementation of similar models in other areas.
