Modelling of Transportation Systems in Agglomerations for ITS Solutions

The traffic analysis and traffic forecasting is a fundamental stage of a cost-benefit analysis (CBA) for planned transport investment projects including ITS systems. The paper presents an analytical complexity of a 4-step travel demand/land use model. A model for 13 cities of the Upper-Silesian Agglomeration (Poland), which has a road network and a public transportation network (tram, bus and railway) of a great density, is presented as an example. It is worth emphasising that this is one of the biggest models of transport networks in Poland – regarding the size of modelled area and the number of cities, which transport systems were represented. According to the new mobility culture (Green Paper (2007) five challenges have been identified and presented in this paper. Also user services of ITS architecture and a micro-simulation model for evaluation of ITS solutions have been presented.
