"Comparing Calibrated Shared Space Simulation Model with Real-Life Data";
Transportation Research Record,
Shared spaces are being implemented in many countries to deal with safety concerns and traffic flow problems on busy urban streets and street crossings. However, shared space concepts could not be tested before being build so far due to the lack of a functioning microscopic shared space simulation. Lane based car following models, currently used in traffic simulation cannot reproduce the high heterogeneity of mixed traffic mode´s non-channelized flow. Our novel approach introduces an extended social force model for vehicles and pedestrians, incorporating social interactions between different modes of transport rather than following a purely rule based approach. The calibration of such a microscopic traffic simulation model using real world data from two shared space sites is presented in this paper. Furthermore, it is shown that the simulation can reproduce real life shared space behavior by comparing it to trajectory and interaction data collected at implemented shared space road designs.
