Improvement of the individual driver behaviour model in order to evaluate the safety level of a traffic flow using microsimulation (ASTRA2004/015)
Overview
Background & policy context:
This research project is connected to the COST 352 action, which analyses the influence of in-vehicle information systems on road safety requirements.
Microscopic traffic simulation tools use certain parameters for vehicle behaviour within a traffic flow.
Objectives:
The main goal is to improve the individual driver behaviour model in order to evaluate the road safety of a traffic flow using simulation models. The parameters to analyse are the vehicle speed, the headway, risk taking, lane changing, weaving, etc.
This research project will isolate the most important safety parameters and propose their evaluation based on microsimulation. Observation of real traffic will allow to adapt the model values to real conditions. In order to validate the developed evaluation model the safety evaluation results of certain modelled road stretches will be compared to the real accident statistics. Finally, the influence of driver information on the safety parameters will be also analysed.
