High passenger density can be simulated time efficiently by means of continuum simulation methods. Critical spots as well as bottlenecks are identified quickly.
|MANDATE/ GOAL:||Analysing safety related aspects of sites|
|ADDED VALUE:||Efficient simulation of high crowd densities|
Dramatic incidents at major events have made it clear to the wider public that studies concerning the diffusion of high pedestrian volume hot spots are urgently needed. Customer inquiries and numerous publications prove the interest of transport specialists.
Because the purely statistical balancing cannot depict build-up and dissipation of critical load peaks, the analysis of the time sequences in highly frequented pedestrian zones (railway stations, airports, shopping centres, sports stadium, amusement parks and cultural sites and venues of major events etc.) is gaining considerable significance with the help of dynamic simulations.
Tools for microscopic simulations are state-of-the-art. They are designed to follow the pedestrians individually in discreet time steps. Only the interpretation of the data gathered produces a macroscopic perspective of the traffic situation. This approach is unsuitable for high crowd density, as the available processing power cannot depict the number of pedestrians in the traffic area. The transition to a macroscopic idealized perspective of the dynamics of traffic by way of people densities and velocity fields (continuum approach) offers a viable solution to this problem.
ASE has pursued a macroscopic approach and developed a simulation tool for a research project. The use of simulation allowed complex situations featuring high visitor numbers to be examined and assessed efficiently. (see figure below.)
