One of the missions that are available in the overview is to address the T problem. In this problem, two entry corridors from opposing sites join in a common exit corridor.
This picture shows the overview at the beginning of the T problem. The solution of the Eikonal equation is displayed with the corridor still being empty. There will be a continuous influx of people from the left and the right side in the beginning. One of the missions that are available in the overview is to address the T problem. In this problem, two entry corridors from opposing sites join in a common exit corridor.
During the presented simulation pass, we have not added any walls. You can see at the joining points of the two corridors the two frontiers colliding. Congestion of people gets build up at that point.
This picture shows how additional incoming people from the side corridors run into the congestion and build up the crowd pressure. This image shows the special visualization mode for the crowd pressure.
In this suggestion of the solution, we have introduced additional walls. The entering corridors have been narrowed down to disperse the crowd before the T junction. We smoothed the side elements to avoid clogging effects at sharp corners.
After we narrowed the entrance corridors, one can observe a much more continuous distribution of incoming persons.
In this case, one can also see the building of a congestion zone. It has much less crowd pressure than the one in the unmodified scenario.
In this case, the compression front safely arrives at the exit.
We have successfully completed the level.
