Influence of Capacity Restraint Functions on Traffic Distribution and Their Practical Use in the Traffic Modelling

Summary/Abstract: The article deals with the issue of capacity restraint functions (curves) determining for roads and their use in the transport model. It describes the procedure for obtaining traffic flow characteristics and the derivation of the parameters needed to create basic restraint BPR function (Bureau of Public Roads). New parameters were then used in traffic assignment process. The impact of parameter changes for routes redistribution on traffic network was evaluated in detail.The practical use of BPR function in the real traffic model is described in the second part. The article presents the method of volume-delay function definition for different model links types.
