Modelling of motorcycle movements in mixed traffic conditions

There exists limited literature that explains the movement of two-wheelers in mixed traffic conditions, where the traffic behaviour is characterised by different vehicle types moving together without much lane adherence, collision avoidance to neighbouring vehicles, response to infrastructure boundaries and following behaviour with respect to multiple lead vehicles. The study aims at filling this gap by proposing a microscopic simulation model exclusively for two-wheeler movement in a mixed traffic environment. The theories of the social force model and the intelligent driver model have been adapted and employed for this purpose. The model performance is assessed using individual trajectory comparison between simulation and observation, and the ability to qualitatively simulate naturalistic two-wheeler behaviour through a test scenario. The simulation results show that the model could visually represent the two-wheeler behaviour in mixed traffic scenarios.
