Simulation of the Olympic site

The Sydney Organising Committee for the Olympic Games used Legion software to assess pedestrian circulation through the Olympic Park. Simulation identified unacceptably high congestion at a crucial juncture of Olympic Boulevard and prompted modifications to the design of Sydney’s Olympic Park.

One modification was the introduction of a pedestrian ‘over bridge’ that had previously been rejected as an unnecessary expense. The bridge closed a circuit of walkways through the park and supported a one-way circulation system, alleviating the problem congestion.

Further analyses of the bridge discovered that there was little improvement in the pedestrian flow rate beyond a width of nine metres. Limiting the width of the bridge to nine metres meant that significant savings on building costs could be made. We also tested and refined an entry system for the park and a corralling system at the entrance to Olympic Park Rail Station.

Simulations found that at the close of peak event days, queues for rail services would grow to 40,000 people and take 2.5 hours to clear. It was clear that stadium egress via the single rail station would require careful management.

“Legion simulations were used in planning the Sydney 2000 Games, and contributed significantly to their success. Athens 2004 planners subsequently adopted Legion. The foresight provided by technology like Legion’s is essential if Olympic standards are to be consistently achieved.”
