Calibration of Pedestrian Models with Respect to Lane Formation Self-Organisation: Exploring Chaos to Obtain Coherent Behavior

Calibration is an essential part in the application of simulation models. This paper presents the calibration of the microscopic pedestrian simulation model Nomad involving quantitative measures of speed-delay relation and the self-organization phenomenon of lane formation. The simulation results have been compared to results of laboratory experiments for unidirectional and bidirectional flows. The results of the calibration indicated that at least one parameter set presented acceptable speed-density relations of biodirectional flows and distribution of the average number of lanes. However, it did not show a good fit of the speed-density relation for unidirectional flows and it presented a strong tendency to produce lower amount of lanes over all density intervals when compared to the experimental results. The insights gained with the calibration in this paper indicate that the inter-pedestrian interactions should be further investigated with a focus on head-on collisions and push from back (pedestrians accelerate too much due to pedestrians that closely walk behind them).
