Vissim distinguishes between the following lane changes:
For a necessary lane change, the driving behavior parameters contain the maximum acceptable deceleration for the lane changing vehicle and its trailing vehicle on the new lane. The deceleration depends on the distance to the emergency stop position of the next route connector.
When a free lane change is performed, Vissim checks whether both desired safety distances are maintained on the new lane:
The safety distance reduction factor is applied to both desired safety distances.
You cannot change the degree of "aggressiveness" for free lane changes. You can, however, influence free lane change by changing the safety distance. You set the parameters for the safety distance in the car following model (Editing the driving behavior parameter car following model).
In both cases of lane change, upstream and downstream, the minimum clearance (front/rear) must be respected (Editing the driving behavior parameter Lane change behavior).
In 2D animation, a current change of lanes, as well as the desire to change lanes is visualized via a small red line to the right or left of the vehicle (representing the indicator), from the defined Lane change distance on. In 3D animation, a current lane change and the desire to change lanes is shown via an indicator, if this is defined for the 3D model of the vehicle.
The desire to change lanes is triggered by:
