Driving state of a vehicle

During a simulation run, you can show the driving state of each vehicle in the network in the Vehicles In Network list (Displaying vehicles in the network in a list).

During the simulation run, you can dynamically allocate the driving state to the vehicle by choosing the relevant color(Dynamically assigning a color to vehicles during the simulation).

Motion state

Notes

Default

Default state, if none of the following states apply.

In queue

The vehicle is stuck in a traffic jam. At least one queue counter must be defined in the network (Modeling queue counters).

In platoon

The vehicle is the lead vehicle or a trailing vehicle in the platoon (Editing driving behavior parameters autonomous driving). As long as a vehicle is approaching a platoon or closing up to it to become part of it, it is not yet part of the platoon and is not yet in the platooning driving state.

Waits for lane change

Vehicle has been waiting for more than 6s at the last position for the lane change (emergency stop distance) (Attributes of connectors).

Ignores interaction vehicle

The vehicle ignores the interaction vehicle to resolve a deadlock situation (Editing the driving behavior parameter Following behavior). This situation may occur, for example, when backing out of a parking space.

Ignores parking blockage

The vehicle wants to park and has been waiting for 60 seconds because another vehicle is preventing it from parking. The driving state of the vehicle is changed to Ignores parking blockage and it can then park.

Ignores priority rules

The vehicle ignores priority rules to resolve a deadlock situation (Modeling priority rules).

In priority rule deadlock

Vehicle is part of a deadlock situation caused by priority rules (Modeling priority rules).

Wants to change lanes

Following the vehicle route makes a lane change necessary that the vehicle has not yet begun.

Changing lane

The vehicle is changing lanes.

Has changed lane

Lane change was performed in the last 6s.

Brakes for lane change

Vehicle brakes as it needs to change lanes.

Brakes cooperatively

The vehicle brakes cooperatively for an upcoming lane change maneuver of a vehicle, from an adjacent lane to its own lane (Editing the driving behavior parameter Lane change behavior).

Loss of attention

Temporary lack of attention of the driver (Editing the driving behavior parameter Following behavior).

Ignores red signal

The vehicle has decided in the last 3 seconds of simulation to traverse a red signal head or a blocked section of a priority rule because its speed was too high to come to a stop in advance.

Brakes heavily

The vehicle brakes heavily (< -3.0 m/s²).

Brakes moderately

The vehicle brakes moderately (-3.0 m/s² to -1.0 m/s²).

Reversing

The vehicle starts waiting at the turning point and reverses to park. As soon as its rear edge reaches the connector leading to the parking lot, the driving state changes to Standard.

For the vehicle reversing, enter the gross or net values (Follow distance, Clearance, Safety distance):

  • Gross: front edge to front edge
  • Net: from the rear edge of the reversing vehicle to the front edge of the vehicle behind it. For the net value, Vissim subtracts the length of the reversing vehicle from the gross value of the attribute (not the length of the vehicle behind it).
