Why Use Microscopic Pedestrian ?

Traditional (macroscopic) pedestrian research assumes that wider space is always needed if the flow demand is increased (to maintain level of services).

The proposed microscopic pedestrian framework argue that to maintain the level of performance, the increase of flow not necessarily demands wider space but better controls.

The study of Helbing and Molnar (1997) as shown in figures below enlighted the idea of microscopic pedestrian research. Broader space or wider door does not necessarily improve the efficiency of pedestrian flow. More efficient pedestrian flow can be reached with less space if we use a different set of rules.

Roundabout reduce space but increase the flow performance such as walking speed. More efficient pedestrian flow can be reached with less space if we use different set of rules.

Addition directional rule of two doors produce better flow performance with the same space.
