Displaying vehicles in the network in a list
During a simulation run, you can show vehicle data for each vehicle in the network in the Vehicles In Network list.
If vehicles are controlled via the COM interface or the driving simulator interface, the following applies:
- Vehicle attribute values may be based on external data, for example on values of the attributes Spacing, Leading target type, Leading target number.
- Vissim‘s car following vehicle model is not used. As the attributesFollowing distance (gross), Following distance (net), Speed difference, Safety distance(gross), Safety distance (net), Interaction state, Interaction target type and Interaction target number are based on the car following model in Vissim, the value of these attributes is 0.
1. Start the simulation (Running a simulation).
2. On the Lists menu, click > Results > Vehicles in Network.
The Vehicles In Network list opens.
Note: In lists, you can use the Attribute selection icon to show and hide attribute values (Selecting attributes and subattributes for columns of a list). |

Description |
---|---|
2D/3D model |
3D model file of the vehicle |
Current 3D state |
Motion states of a pedestrian or a vehicle of the vehicle category Pedestrian, which can be stored in the 3D model file. If the model file contains three or 21 motion states, the Current 3D state is automatically adjusted during the simulation run, depending on the distance traveled and the speed applied to the direction of movement. This ensures a realistic simulation, especially of waiting pedestrians. |

PauseAnim |
3D animation maintains its current state until Pause animation is deactivated. |

Examples of when a vehicle is in the state Blocked while leaving parking space:
In dynamic assignment, there is no return path to a route. When the vehicle leaves a parking space, it is given a new route. Dynamic assignment does not support result attributes of a return path. With dynamic assignment, the vehicle is not in a parking state when driving to a real parking space, as long as it has not been assigned a parking space. You can show the vehicle’s parking state in color during the simulation. The parking state takes into account the effects of routing decisions made in the same time step. |

Safety distance (gross), Safety distance (net) |

With each simulation step, Vissim calculates the remaining distraction duration based on the Duration distribution selected for the driving behavior Misestimation. This has an effect on the driver (Editing the driving behavior parameter driver error). |

Leading target number |
Number of closest preceding vehicle |
Spacing, Clearance |
Distance [m] to the interaction object Vehicle or Network Object. Vissim calculates this value before the time step and thus before any movement of the vehicle. This value depends on whether the vehicle interacts with its preceding vehicle or with a downstream network object (Position near interaction object relevant for gross and net value). The clearance specifies the following distance depending on the interaction object:
A red signal is considered an interaction object like a vehicle in front, a green signal is not. |

|
Lateral deviation (distraction) |
Change in the lateral deviation of the vehicle within the current time step, caused by distraction of the driver. The vehicle deviates temporarily from the route. Vissim calculates the lateral deviation (distraction) based on the following vehicle behavior attributes that have an effect on the vehicle (Editing driving behavior parameters):
In addition,
If the driver is distracted, the Temporary lack of attention attribute will also have an effect. If the vehicle accelerated in the preceding time step, this acceleration is maintained (Editing the driving behavior parameter Following behavior).
If the lateral deviation is no longer effective on the basis of the Distraction duration distribution attribute, the vehicle will return to its desired lateral position. |
Lateral deviation (excessive speed) |
Change in the lateral deviation of the vehicle within the current time step, caused by excessive speed. The vehicle is temporarily not well handled through the bend or drifts sideways. Vissim calculates the lateral deviation (excessive speed) based on the functions Curve speed and Drifting speed (Defining curve speed), (Using lateral drift speed). The value of the Radius attribute defined for 3D points of the link is included in the calculation of the critical speed (Attributes of links).
|
Lateral deviation (distraction) and Lateral deviation (excessive speed) have no effect on the following vehicles:
Lateral deviations do not lead to the interaction of another vehicle, such as a vehicle approaching. |
Position near interaction object relevant for gross and net value
Vissim measures the gross and net values of the attributes Following distance, Clearance and Safety distance from the front edge of the vehicle to a position near the interaction object. This position depends on various factors, such as whether the vehicle interacts with another vehicle or with a network object, its markers, and the network object type.
In the case of attributes Spacing and Clearance, the interaction object is the preceding vehicle or the closest interaction object in the direction of travel.
