7 Simulation of Pedestrians
7.2 Evaluation Types for Simulations of Pedestrians
This section describes the options for the evaluation of pedestrian traffic.
Similar to the vehicle information (cf. section 11.6), the online data of
selected pedestrians can be displayed in separate windows, cf. section 7.2.5.
Other evaluations can be stored in files or databases: Via menu EVALUATION
– FILES the window Evaluations (File) can be called. The [PEDESTRIANS] tab
allows for the configuration of pedestrian traffic evaluations, cf. section 10.1.
7.2.1 Pedestrian Travel Time Measurements
A travel time measurement for pedestrians consists of a “directed” pair of
pedestrian areas (using existing normal areas): One of these is the starting
area – pedestrians entering it get tracked by the device until they enter the
corresponding destination area. When this happens, the following
observables are recorded and written to an ASCII file associated with the
travel time measuring device:
● Arrival time at end of the measurement
● Measurement number
● Pedestrian number
● Pedestrian type
● Total distance walked between start and end of the measurement
● Total time needed to walk from start to end of the measurement
● Sum of “time lost” while walking between start and end of the
measurement. This is the sum of “wasted times” in every time step
computed from the difference between actual walking speed and desired
walking speed (if walking slower than intended). Attention: Delays
caused by walking along non-optimal paths etc are not regarded.
● Sum of “time gained” while walking between start and end of the
measurement. This is analog to the value above but summed up when
actually walking faster than desired.
● Deviation between the pedestrians’ current speeds and the desired
speeds during walk from start to end.
Contents and format of evaluation files are shown below.
