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.

CurAnim

Name of animation currently used for the relevant 3D model. This allows you to access the animation with attribute modifications, attribute decisions, or scripts.

PauseAnim

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

LoopAnim

After the current 3D animation has reached its final state, it starts again from the beginning. Otherwise, the animation returns to and remains its default state, unless Retain final animation state (3D) has been activated.

RetainFinAnimState

The current 3D animation stops when it has reached its final state and remains in it, unless Loop animation has been activated.

AnimSpeed

Factor for scaling the animation speed.

• Value > 1: The animation runs faster. Depending on the selected value and the simulation parameter Simulation resolution you cannot display every single state. The display may appear less fluid.
• Value < 1: The animation runs slower. As a result, each individual state is displayed for a longer time The display may appear less fluid.

NumStatesTot

Total number of states of all animation sequences of the 3D model

Number of stops

Number of stops (cumulated): All situations in which a vehicle comes to a standstill (speed = 0). This includes stopping at the turning point after backing out of the parking space before the vehicle continues driving forward.

The Number of stops does not include stops at PT stops and in parking lots.

Dwell time

Dwell time [s] at a stop sign, in a parking lot or at a PT stop.

For PT stops: Actual dwell time according to PT line-specific attributes (Calculating dwell time according to the advanced passenger model).

When the dwell time is set to 0, the vehicle drives off.

OrientationAngle

Orientation angle: angle (degrees) of the orientation vector of the current vehicle orientation

Occupancy

Defines the number of persons or passengers in a vehicle. This value is output before and after boarding and alighting.

Following distance (gross),

Following distance (net)

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 the interaction state Closing up (Interaction state of the vehicle):
• Following distance (gross): distance from the front edge of the vehicle to the front edge of the interaction vehicle
• Following distance (net): distance from the front edge of the vehicle to the rear edge of the interaction 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 (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. (Position near interaction object relevant for gross and net value).

Parking state

• None: The vehicle is in none of the following parking states:
• Blocked while leaving parking space: The vehicle is parked in the parking space and wants to leave, but is blocked by other vehicles.
• Driving to parking space: The vehicle is driving on the parking route.
• Parked: The vehicle is parked with speed = 0 in the parking space. A vehicle’s parking state is not Blocked while leaving parking space: If the vehicle's dwell time is increased while it is parking, it is considered parked for this period; once a dwell time of 0 is reached, it cannot be increased again.
• Parking request rejected: The vehicle could not be assigned a parking space, as the requirements for assignment are not met (Modeling parking and stopping on the roadside).
• Waiting for free parking space: The vehicle is located in front of the parking space and is waiting until it becomes available. Prerequisite: Wait is selected for the attribute Full occupancy behavior of the parking routing decision and all parking spaces of the parking lot are occupied. If all parking spaces are occupied when the vehicle is located or is driving over the parking routing decision and a vehicle is already waiting in front of each parking space, the vehicle will not be assigned a parking space in front of which it can wait.
• The speed of the vehicle = 0.
• Its parking state is not Parked.
• The front edge or rear edge of the vehicle is still in the parking space it wants to leave.
• If the length of the vehicle requires more than one parking space, it will not wait and Vissim will not assign it a parking route.

Examples of when a vehicle is in the state Blocked while leaving parking space:

• The vehicle wants to back out of the parking space because its dwell time has reached 0, but it waits because of the traffic in the drive aisle.
• The vehicle has parked in the first row and is blocked by parked vehicles in the second row.
• At a very short distance downstream of the parking space, there is a signal controller or stop sign, so that the vehicle must stop while it is still in the parking space with its rear edge.

• Back to route: Vehicle was in the parking state Parked, is currently not in the parking state Blocked while leaving parking space and is getting back on its vehicle route. This may include backing out of the parking space until the turning point at which the vehicle changes between forward and reverse gear as well as waiting for the change of direction time.

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)

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).

Gradient

Gradient for the vehicle used in the simulation :

• If the attribute Z-coordinates is selected in the network settings for Link gradient based on, the gradient is calculated from the z-coordinates of the front edge and rear edge of the vehicle.

• If the Gradient attribute is selected, the gradient will correspond to the gradient of the link at the front edge of the vehicle.

In both cases, the sign of the gradient is reversed when the vehicle is driving in reverse.

Remaining distraction duration

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).

Delay time

Difference between optimal (ideal, theoretical) driving time

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:

• 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. (Position near interaction object relevant for gross and net value).

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

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.

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 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).

• 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 Railway category
• Vehicles driving in the reverse direction

Lateral deviations do not lead to the interaction of another vehicle, such as a vehicle approaching.
