Abstract

When the bad weather occurs, the visibility will inevitably decrease, which will limit the field of driver's vision, reduce the driver's perception of near-neighboring vehicles and affect the driver's driving state. To investigate the impact of visibility during vehicle operation in adverse weather, we integrate the visibility of adverse weather into a backward looking car-following (VBLE-CF) model. Furthermore, theory analyses are performed to get neutral stability condition and mKdV equation concerning the visibility of adverse weather. Moreover, simulations with respect to headway and speed verify that both visibility and backward-looking phenomena have a positive expansion of traffic stable state. Additionally, both visibility and backward-looking phenomena are beneficial to cutting down energy consumption.
