Title: PROBABILISTIC MODEL OF TRAVEL DENSITY IN TOWNS
Abstract: To determine land use density, several investigations have been made in many countries. However, they usually treat only population density, rarely the density of employment and number of places in schools. All these parameters influence trip generation. The authors claim that the formulas traditionally estimate the average density and they are not taking considering the variability of densities. Furthermore, land use density models have no direct connections to travel density model. The subject of investigations, summarised in this paper, are middle-sized Polish towns, with a range of population from 30 000 to 100 000 inhabitants. The statistical sample were five towns, each divided into 26 to 53 land use zones. There were altogether 175 elements of sets, making up values of dependent and independent variables. Four types of land use have been distinguished: 1) population density; 2) density of work places; 3) density of work places in services; and 4) density of places in schools excluding primary schools. In all cases, the current situation of land use has been taken into consideration. The four types of density measures are the dependent variables in the model presented. The distance between town centre and weighed middle point for individual land use zones is forming the independent variable. For the covering abstract of the conference see ITRD E205613.
