Interaction state of the vehicle

The vehicle interacts with other vehicles and network objects. You can define the number of these interaction vehicles and interaction objects that the vehicle is aware of in order to interact with them (Editing the driving behavior parameter Following behavior).

The interaction state influences the acceleration or deceleration of the vehicle and shows the reason for this reaction. During a simulation run, you can show the interaction state of each vehicle in the network in the Vehicles In Network list (Displaying vehicles in the network in a list).

Interaction state	Description
Close up	The vehicle slowly closes in the following cases: There is a stationary vehicle in front of it while it is pulling out of a parking space in reverse onto its original link and upstream there is a stationary vehicle or a vehicle approaching until it reaches an obstacle, for example, a signal head, a stop sign, priority rule, conflict area.
Brake BX	Braking at the desired safety distance (before reaching the safety distance), approaching (Driving states in the traffic flow model according to Wiedemann).
Brake AX	Braking at the desired safety distance (after reaching the safety distance) (Driving states in the traffic flow model according to Wiedemann).
Brake ZX	Target deceleration to an emergency stop distance for a lane change or a reduced speed area.
Brake LCH	Slight deceleration for a lane change in order to wait for the next upstream gap in the adjacent lane.
Brake cooperative	Cooperative braking to allow another vehicle to change lanes (setting via parameter Maximum deceleration for cooperative braking) (Editing the driving behavior parameter Lane change behavior).
External	Acceleration/deceleration is controlled by an external driver model DLL (Activating external driver model via Driver Model DLL file).
Follow	Vehicle tries to follow a leading vehicle at its speed (Driving states in the traffic flow model according to Wiedemann).
Stop	The vehicle stops.
Loss of attention	The parameter Temporary lack of attention is currently active, there is neither acceleration nor braking except for an emergency braking.
Pass	Acceleration/deceleration to reach a permitted speed depending on the lateral distance for passing another vehicle in the same lane or an adjacent lane.
Free	Vehicle is not affected by any relevant preceding vehicle. It tries to drive at desired speed, free driving (Driving states in the traffic flow model according to Wiedemann).
