DISAGGREGATE MODEL OF MODE CHOICE IN INTERCITY TRAVEL

The development of a policy-sensitive model of mode choice in intercity travel is discussed. The disaggregate logit model is based on the National Travel Survey of 1977, supplemented by service information from industry guides. Automobile, air, bus, and rail market shares are estimated from information on cost, travel time, frequency, terminal access, automobile availability, and trip purpose. By all measures, the model performs well. It is applicable on a national, regional, or route-by-route level. Forecasts are performed for a variety of national and regional scenarios. (Author)
