3D model file of the vehicle

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.

Current state of vehicle turn signal. Corresponds to current visualization during simulation:

• No: Vehicle is not indicating
• Links
• Right

Following distance

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.

Based on the interaction object and the interaction state Close up , the following distance specifies the following distance:

• If vehicle is not in Closing up interaction state: the distance between the front edge of the vehicle and the front edge of the interaction vehicle (Interaction state of the vehicle).
• If the vehicle is in the interaction state of Closing up, the following distance indicates the distance to the expected waiting position of the vehicle ahead.
• When the vehicle interacts with a network object downstream, the following distance indicates the distance between the front edge of the vehicle and the start section of the network object, if the latter has a start and destination section, for example, in a reduced speed area or at a stop. If only a single marker represents the network object, the distance from the front edge of the vehicle to this marker is specified, for example, with a stop sign.

Spacing

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 (Displaying vehicles in the network in a list). The clearance specifies the following distance depending on the interaction object:

• Trailing vehicle - interaction vehicle: distance between the front edges of the two vehicles

A red signal is considered an interaction object like a vehicle in front, a green signal is not.

Safety distance

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 front edges of the two vehicles includes the speed of the trailing vehicle (Defining the Wiedemann 74 model parameters)

• Vehicle - network object: ax, the “stochastically smeared” base value for the standstill distance of the vehicle (Defining the Wiedemann 74 model parameters).

Destination parking lot

Public transport - dwell time (total)

Total of all stop dwell times

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 - dwell time (current)

• 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.

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.

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.
