The first Grand Prix to be held in Singapore in recent times took place in 2008. The circuit
utilised the road network throughout the Central Business District including the sites of the
conference centre and several congested arterial routes. Managing this landscape for
commuters, public transport services, tourists and race personnel consequently provided
operational and managerial planning considerations in the lead in and during event days.
To investigate methods of amelioration within the Singapore network, PTV developed a
VISUM network incorporating all major land uses and junction detail within the study area.
The transport setting also incorporated significant public transport services that deliver tens
of thousands of persons to the city each day. Transport operations were then exported
directly into VISSIM for simulation modelling, allowing for accurate representation of signal
phasing, pedestrian behaviour at crossings and route choice for traffic through the network.
This approach ensured direct consistency of decisions made by drivers in the strategic
VISUM model when simulating the behavioural choices through the VISSIM network. The
modelling methodology allowed for accurate scenario testing and evaluation of schemes in
the lead up to the event, including road closures and re-routing of public transport services to
alleviate network delay.
