In order to deeply analyze and describe the characteristics of car-following behaviour of turning vehicles at intersections, the\nfeatures and application conditions of classic car-following models were analyzed firstly. And then, through analysing the\nrelationship between the maximum velocity of car-following vehicles and the turning radius of intersection, the differences in key\nvariables between turning and straight car-following behaviour were identified. On the basis of Optimal Velocity (OV) model, a\nTurning Optimal Velocity (TOV) car-following model with consideration of turning radius and sideway force coefficient at\nintersections was developed. PreScan simulation was employed to build the scene of turning car-following process at an intersection.
