Abstract: This paper investigates the accuracy of the probit approximation based solution of the spatial aggregation problem of traffic assignment. It tests the normal approximation to uniform intrazonal travel times and the Clark approximation to the solution of the choice probabilities between alternatives characterized by normally distributed travel times. Some guidelines for using the technique are developed.
