7.1.8.3 Static partial routes of pedestrians: Use cases
Basically, there are two different ways to make use of static partial routes.
► Use case 1 is to easily distribute pedestrians with long routes on rather
narrow spaces without making them forget their main route.
► Use case 2 makes use of the “catch all” ability of static partial routing
decisions: it helps to spatially distribute pedestrians in a better way, if
their current position already suggests a certain further routing variant: In
this case, typically only one route is attached to a routing decision.
In the following cases, a partial routing decision can apply to a pedestrian:
► If the pedestrian enters an area carrying a partial routing decision.
► If the pedestrian starts to follow a new main route.
This means, there are cases in which a partial routing decision is ignored,
though following a partial routing decision could be expected under certain
circumstances:
► Two areas called A and B carry a partial routing decision each (a and b).
Area B is located completely within area A. Thus, a pedestrian will
always step on area A first and might then step on area B, if applicable.
The main route and the partial routes are defined in the following way:
Partial routing decision b applies to the pedestrian, but partial routing
decision a does not. However, partial routing decision a would become
valid, if partial route b had been added to the main route. Nevertheless,
partial routing decision a is not used – neither right after partial routing
decision b nor when the pedestrian merely stands on area A after leaving
from area B.
► During the simulation, a pedestrian enters the network and receives a
main route. At his position, there are two more partial routing decisions
called a and b. Partial route a leads to an area that also carries an
intermediate destination of the pedestrian’s main route, but partial route b
does not. Partial route b leads to an area that also carries an
intermediate destination of partial route a. Nevertheless, only partial
routing decision a is regarded, whereas partial routing decision b is not,
since it is required for the check for existing partial routing decisions that
a normal routing decision must have been performed. However, if partial
routing decision b is not located directly at the position where the
