Meso critical gap |
MesoCriticGap |
Meso critical gap: The meso critical gap defines the temporal distance between two successive vehicles in the major flow that a vehicle in a minor flow needs to enter the node. The meso critical gap extends from the back edge of the preceding vehicle to the front edge of the tailing vehicle. The time required for the effective length of the preceding vehicle is not included. This allows you to also model realistic behavior when dealing with a large share of overlong vehicles. When defining values for the meso critical gap, you can refer to established manuals such as the HBS or HCM. In deviation from the definition used here, in the manuals, the meso critical gap is defined for between the front edges of successive vehicles. The meso critical gap is a conflict area attribute (Attributes of conflict areas). Edit this attribute in the Meso Turn Conflicts list or in the Nodes - Meso Turn Conflicts coupled list (Attributes of nodes). The values are saved with the respective conflict areas as the attribute meso critical gap (Attributes of conflict areas). The default value is 3.5 seconds, with a range from 0 seconds to 1,000 seconds. The meso critical gap does not take effect in the mesoscopic simulation if the status of the conflict area is Undetermined. |
