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. From the Lists menu, choose > 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).

Attribute	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.

Safety distance (gross), Safety distance (net)	Safety distance [m] to the interaction object vehicle or network object that the driver wants to keep. Vissim calculates this value before the time step and thus before any movement of the vehicle. The value depends on whether the vehicle interacts with another vehicle in front or with a downstream network object: Trailing vehicle - interaction vehicle: the calculation of the safety distance between the edges of the two vehicles includes the speed of the trailing vehicle (Defining the Wiedemann 74 model parameters) Safety distance (gross): distance from the front edge of the vehicle to the front edge of its preceding vehicle Safety distance (net): distance from the front edge of the vehicle to the rear edge of its preceding vehicle Vehicle - network object: ax, the “stochastically smeared” base value for the standstill distance of the vehicle (Defining the Wiedemann 74 model parameters). The safety distance runs between the front edge of the vehicle and a position in the network object that varies depending on the network object type (Position near interaction object relevant for gross and net value).
Delay time	Difference between optimal (ideal, theoretical) driving time
Leading target number	Number of the relevant 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: Trailing vehicle - interaction vehicle: Following distance (gross): distance from the front edge of the vehicle to the front edge of its preceding vehicle Following distance (net): distance from the front edge of the vehicle to the rear edge of its preceding vehicle Trailing vehicle - network object: When the vehicle interacts with a network object downstream, the Following distance (gross) and Following distance (net) refer to the distance between the front edge of the vehicle and a position in the network object that varies depending on the net object type.

The following applies for the following PT attributes: Before and after boarding and alighting, the values are zero. Values are only displayed, when the PT vehicle is stationary at the PT stop. During boarding and alighting, the values are current for each time step, with the exception of the attributes Public transport - waiting passengers and Public transport - waiting time (average). For real passengers, the attribute values Public transport - waiting passengers and Public transport - waiting time (average) are evaluated when the vehicle stops at the waiting area. These values do not change while the PT vehicle is stationary.
Public transport - alighting passengers	Number of alighting passengers at the current PT stop
Public transport - boarding passengers	Number of boarding passengers at the current PT stop
Public transport - passenger service time	Total passenger service time [s] at the current stop. The Public transport - passenger service time is counted up during the dwell time. Per default, the Public transport - passenger service time is one time step at the beginning of the dwell time. This ensures that at the end of boarding and alighting, the Public transport - passenger service time includes the entire Public transport - dwell time (current).
Public transport stop	Number of current stop
Public transport - dwell time (current)	Expected remaining dwell time at current PT stop. Slack time fraction is taken into account.
Public transport - waiting time (average)	Average waiting time of boarding passengers at the current PT stop. For real pedestrians the waiting time is evaluated with the time step of arrival.
Public transport - lateness	Lateness in departing from the current PT stop (>0 = late)
Public transport - waiting passengers	Number of waiting passengers at the current PT stop. For real pedestrians: The number is only evaluated with the time step of arrival and displayed during time steps in which the PT vehicle is stationary. For the calculated number of boarding and alighting passengers: The number calculated is displayed with the time step of PT vehicle arrival and is displayed in the time steps during which the PT vehicle is stationary.
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): The value of the Distraction probability must be greater than 0. The value of theDistraction duration distribution defines the distraction duration, i.e. the period of time until the vehicle starts to return to the original route. While the vehicle is returning to its original route, the Lateral deviation (distraction) can again affect the vehicle. The value of the Distraction lane angle distribution defines the angle at which the vehicle deviates from the route as radian measure. Value range radian: 0 rad to 1.5 rad. In addition, the vehicle must not change lanes during the current time step. No lateral deviation should affect the vehicle. The direction of the lateral deviation to the left or right is based on a probability 50 %. If the vehicle deviates to a neighboring lane due to a lateral deviation, this is not considered a lane change. If the vehicle is also affected by a lateral deviation (excessive speed), in the same direction to the left or right as the lateral deviation (distraction), the vehicle will follow the lateral deviation with the higher value. Lateral deviations are not added. If the vehicle is also affected by a lateral deviation (excessive speed), in the other direction to the left or right as the lateral deviation (distraction), the vehicle will follow the lateral deviation (excessive speed). If a lateral deviation has an effect on a vehicle overtaking within a lane, the vehicle can select a new desired lateral position to complete the overtaking maneuver. 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). Positive value: Vehicle deviates to the left. Negative value: Vehicle deviates to the right. Default 0 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 Critical speed and Drifting speed (Defining critical 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). Positive value: Vehicle deviates to the left. Negative value: Vehicle deviates to the right. Default 0
Lateral deviation (distraction) and Lateral deviation (excessive speed) have no effect on the following vehicles: Vehicles used for the simulation method Meso Vehicles of the vehicle type within the Railwaycategory Vehicles driving in the reverse direction 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 the Clearance attribute, the interaction object is the preceding vehicle or the closest interaction object in the direction of travel.
