ABSTRACT: For the verification and validation of microscopic simulation models of pedestrian flow, we have
performed experiments for different kind of facilities and sites where most conflicts and congestion
happens e.g. corridors, narrow passages, and crosswalks. The validity of the model should
compare the experimental conditions and simulation results with video recording carried out in
the same condition like in real life e.g. pedestrian flux and density distributions. The strategy in
this technique is to achieve a certain amount of accuracy required in the simulation model. This
method is good at detecting the critical points in the pedestrians walking areas. For the calibration
of suitable models we use the results obtained from analysing the video recordings in Hajj 2009
and these results can be used to check the design sections of pedestrian facilities and exits. As practical examples, we present the simulation of pilgrim streams on the Jamarat bridge (see Figure 5).
The objectives of this study are twofold: first, to show through verification and validation that
simulation tools can be used to reproduce realistic scenarios, and second, gather data for accurate
predictions for designers and decision makers.
