Interaction between Transport Planning and Spatial Development

摘要

In the current transportation forecasting models, which are used to calculate traffic patterns connected with potential spatial alternatives, the interdependence between transport infrastructure and spatial development is not taken account of. On the basis of the available data concerning the population, the employed population and employment, the number of departures and arrivals per zone is calculated (the trip generation). These arrivals and departures per zone are included in the calculation models as hard constraints. By the introduction of elastic constraints, it is possible to have the marginal amounts of the origin-destination matrix (arrivals and departures per zone) varied. The more these constraints are left alone, the more influence the quality of the infrastructure will have on the total amount of arrivals and departures per zone. The paper is dealing with the model with elastic constraints. After a derivation of the model on the basis of the traffic engineering theory, some spatial developments in the Randstad will be calculated by using the model.
