Computerized Transportation Planning Models for Site Impact Analysis: Precision or Complexity?

Document Type: Proceeding Paper

Part of: Site Impact Traffic Assessment: Problems and Solutions

Abstract:

Computer based travel forecasting models are now being widely used in the analysis of the traffic impacts of proposed developments. They are commonly used to identify improvements needed to maintain adequate levels of service, and to identify the number of trips on each specific roadway link attributable to individual developments. However, model calibration standards are such that the noise in the model is often greater than the impacts of development. Extreme caution must be exercised when applying computerized models to site impact analysis, particularly when the results are used as a means of determining developer's financial responsibility.
