THE PROBLEM-ORIENTATION OF TRAFFIC MODELS

ZUR PROBLEMORIENTIERUNG VON VERKEHRSMODELLEN

With the aid of traffic models, traffic volumes, traffic flows and traffic loads are determined in relation to settlement structure, traffic infrastructure and behaviour patterns of the inhabitants. In small communities with less than 25000 inhabitants the data necessary for the traffic model are usually not available, but it is generally possible to get an overall view of the traffic conditions. The use of traffic models is described for medium-sized towns with 80000 inhabitants. Input data on traffic generation, traffic distribution, modal choice and the choice of route are necessary for the model. Traffic functions are divided in a simplified manner into journeys to work, school traffic and other traffic. Important basic parameters are provided by values for specific traffic incidence with time distributed over the day for shopping traffic, leisure traffic, etc. In large towns whose road network can no longer be measured according to business traffic peaks, a special investigation of commercial traffic is necessary. This type of travel purpose is still some way off incorporation into a model-analysis which is useful for practical traffic planning. Very varied estimates are available for that section of so called inner cell commuters, some of whom travel to work on foot. (TRRL)
