Effects of restrained highway speeds on projections of travel patterns and modal choice.

An investigation was made in three stages: at the time when choice of travel mode was made, at the time of trip distribution, and at the time when automobile and transit trips are assigned to their respective networks. The comparison is made against the simulated travel pattern that is based on highway speeds. Results indicate that a 15% increase in transit system accessibility produces approximately a 10% increase in transit trips.
