The using of 3-dimensional modelling for the calculation of regional transport demand matrix

Vyuziti 3D modelovani pro stanoveni prepravnich vztahu na regionalni urovni

The traffic demand matrix belongs to the most important data for a traffic impact assessment and proposal of measures in a crucially stressed area. This matrix can give an answer to the question from where and to where people travel for different purposes and it helps to identify relations between traffic origins and destinations. The matrix either can be deduced from a directional traffic census (car transport matrix) or calculated with the help of trip distribution processes. The 2-dimensional trip distribution is the most common method. In this case, a traffic production and attraction as well as a function of distance or travel time between all zone pairs are used as input data. The paper will present less used trip distribution method - 3-dimensional modelling - in Middle Bohemian Region, where transport demand between districts known from Czech National Population Census has been used as a "3rd dimension". This "3rd dimension" better take into account that the demand inside a district is stronger than inter - district demand. The modelling has been performing by Canadian EMME/2 software and it enables the generation of more realistic transport demand matrices for certain trip type (commuting). The resulted matrix is a fundament for next processes: model network assignment and calculation of traffic volumes and emissions, creation of model development scenarios and evaluation of planned constructions and measures from the viewpoint of its environmental impacts.
