Special generators in tasks of transportation demand assessment

Abstract

The article addresses an issue of public attraction facilities in tasks of transportation planning and, in particular, in tasks of transportation demand assessment. Special attention is paid to facilities which shall be classified as special generators. Special generators are facilities with trip generation characteristics differing from those of the facilities related to residential, commercial and industrial territories. It is suggested to use the trip generation value as a key indicator for the significance of a facility as a special generator. Such value can be used to divide all facilities into classes determining the significance of its accounting and distinguishing in tasks of traffic simulation and transportation demand assessment. Examples of results in assessing dependencies of the specific generation values regarding trips to special generators and the share of trips to such facilities grouped according to modal split are given.
