dc.description.abstractA better understanding of psychophysical influencing factors of drivers and the resulting driving maneuvers in response to dynamic traffic phenomena is vital to the improvement of traffic flow theory and its applications in Intelligent Transportation Systems (ITS). This 4-year research project aims to propose a generalized car-following behavior model under driver perception uncertainties to explicate the dynamics of driver car-following decision process. The 1st-year research project aims to characterize driver behavior during car following under perception uncertainty conditions. Car following is deemed the outcome of the intuitive response of a driver to instantaneous optical stimuli in the visual field driven by changes in surrounding traffic environments. Such optical stimuli are transformed into psychophysical momentums, and then used to approximate the driver speed adjustment in the optical-flow-induced stimulus-response process. The 2nd and 3rd year projects further investigate the potential trade-off relationships among psychophysical factors including reaction time, perceived safety distance, perceived relative speed, as well as stimulus intension/frequency. My study purpose here is to improve the proposed generalized car-following model so as to comprehensively characterize the dynamics of driver car-following behavior under perception uncertainty contexts. The 4th-year project will further take account of external factors (e.g., lightness/darkness) and driver characteristics in the proposed model so as to comprehend the resulting influence in the proposed model. In the aspect of model testing and experimental design, I plan to use both a microscopic traffic simulator PARAMICS and driver simulator calibrated using processed video-based data to demonstrate the proposed model’s validity for real applications. Hopefully, the proposed generalized car-following behavior model is expected to link the gaps among the areas of traditional car-following theory, driving psychophysics, and ITS. It is also expected that such a proposed generalized perception-stimulus-response car-following behavior model can throw more light into its application to driver psychology and response in anomalous traffic environments to improve road safety. Furthermore, the study can be regarded as a frontier research of social physics providing in-depth understanding and applications of applied physics in social science.en_US
