Modelling drivers' car parking behaviour using data from a travel choice simulator

By P.W. Bonsall and I.A. Palmer

Abstract

This paper reports on models developed from data collected using the PARKIT parking\ud choice simulator. PARKIT provided an experimental environment in which drivers’\ud choice of car parks, and of the routes chosen to reach them, could be observed and the\ud influence of different levels of parking-stock knowledge (derived from experience or from\ud information provided via roadside message signs) monitored. Separate models were\ud estimated for the drivers’ initial choice of car park and for their revision of that choice as\ud their journey progresses and they learn about actual conditions. The importance of price,\ud walking time and driving distance is confirmed but the addition of variables describing the\ud drivers’ choices on previous days, their expectations and their immediately preceding\ud route-choice, greatly improved the models’ explanatory power. It is noted that variables\ud such as these are not generally considered because they are rarely available to the\ud modeller. Different discrete choice model structures were found to be appropriate for\ud different decisions. Route choice was represented as an exit-choice model (whereby each\ud journey is treated as a sequence of decisions – one at each intersection encountered). The\ud paper discusses the incorporation of these choice models into a network assignment model\ud and concludes that much of the power of the choice models is lost if the network model is\ud not able to support use of information about travellers’ socio-economic characteristics and\ud knowledge of the network and about the detailed network topology
