7 Simulation of Pedestrians
pedestrian has been generated but on an area the pedestrian entered in
the next time step, then it will be performed, of course.
Due to these restrictions endless loops which might arise in a single time
step can be avoided.
Use case 1
Imagine pedestrians coming from different rather remote sources on routes
with quite a few intermediate destinations, passing one common area with
alternative routing options independent of the pedestrians’ source or
destination and walking (with source-dependent ratios) to different remote
destinations and again quite a number of intermediate destinations on their
paths to come. In this case it is very helpful to model the route choice on the
common area with special partial routes that pose only local changes to the
routes and not to the path to come. As an example see the following figures,
where the long up- and downstream route legs have been omitted. (Normal
routes are depicted yellow, partial routes appear orange.)
