Abstract:Driver's disturbance risk preference is defined as the driver's reaction degree to the disturbance, which is one kind of driver's attributes and can be expressed by the disturbance risk preference coefficient. This paper first attempts to investigate the effects of the driver's disturbance risk preference heterogeneity and its system thresholds on traffic flow instability based on a car-following model. An analytical analysis is conducted to obtain the calculation formulas of traffic system unstable threshold … Show more
