Editing the driving behavior parameter Meso

Mesoscopic simulation uses a simplified vehicle following model (Car following model for mesoscopic simulation) for modeling vehicle behavior.

1.  On the Base Data menu, click > Driving Behaviors.

The list of defined network objects for the network object type opens.

The list shows driving behavior parameter sets. Some driving behavior parameter sets can be predefined.

By default, you can edit the list (Using lists).

You can edit all driving behavior parameters for lane change, lateral behavior and following behavior in the list or in tabs with the following steps.

Notes: In lists, you can use the  Attribute selection icon to show and hide attribute values (Selecting attributes and subattributes for columns of a list). Hatch-shaded fields cannot be edited (Structure of lists).

2.  Right-click the entry of your choice.

3.  On the shortcut menu, click Edit.

The Driving Behavior window opens.

4.  Select the Meso tab.

5.  Make the desired changes:

Long name	Short name	Description
Meso reaction time	MesoReactTime	Temporal safety distance in seconds (response time), default value 1.20 s
Meso standstill distance	MesoStandDist	Meso standstill distance of vehicles in meter, default value 2.00 m. Meso standstill distance + vehicle length = effective vehicle length for mesoscopic simulation The vehicle length depends on the vehicle type.
Meso maximum wait time	MesoMaxWaitTime	Meso maximum waiting time: Period in seconds after which a vehicle waiting at the node entry enters the node from a minor flow direction, even if the time gap in the major flow direction is too short. This way, a minimum number of vehicles of the minor flow direction get to enter the node, despite the heavy traffic in the major flow direction. Default 120 s, value range 0 s to 100,000 s.
