Abstract
The Highway Capacity Manual (HCM) suggests estimating the average green time for performance evaluation of vehicle-gap based traffic operation and provides an average green time estimation model. This paper proposes a new model that overcomes the shortcomings of the HCM model. Through a comparison study based on 1,196 pieces of hypothetical test data, it was found that the average green times estimated by the proposed method yields a much better one-to-one linear relationship to the simulation data representing field data than that from the HCM method in both exclusive-only and shared-permitted cases. The R/sup 2/ values of the proposed and HCM methods with these cases are 0.90 and 0.86, and 0.56 and 0.57, respectively.
