The influence of the optimal velocity deviation on the traffic evolution process under lane change in two-lane lattice model

Abstract

Abstract In a real traffic environment, there is always a certain deviation between the real traffic information and the expected traffic information, which definitely has an important impact on traffic flow. Consequently, the optimal velocity deviation effect (OVDE) is taken into account to build a novel lattice model on two lanes. Moreover, the influence of OVDE on the linear stable condition is investigated, which shows that the OVDE plays a positive stable effect in two-lane traffic flow. Also, the OVDE can relieve more traffic congestion on two lanes via numerical simulations concerning the density and the hysteresis loop.
