Abstract
  • This research work attempts to construct econometric models of the demand for travel. Basically, the models depend on a relationship between the amounts of travel demand and household income, but there is an inbuilt sensitivity to the level of service provided by different transport systems. To achieve this, a new method of valuing non-working time was developed. By applying the principle that the amount of travel is governed by household budgets of time and money it is possible to estimate the effect on the numbers of trips and their lengths caused by modifying the road system or by otherwise changing the cost of travel. The models therefore depart from the traditional four stage transportation planning techniques and they effectively combine modal choice with trip generation. To complement these travel demand models a new approach to traffic assignment has been developed. The method uses concepts of "relative attractiveness" and "accessibility" of routes to simulate drivers' choice of route. Additionally, this process provides estimated values of parameters required as "feedback" to the travel demand models. An important feature of the work is that all models are simple in concept and application and they require relatively small amounts of data to be collected.
