How the simulation is done
Data is entered into the computer and simulation is run. The below scenarios may be tried out:
- Timing of lights varied to see how traffic flow is affected
- build up number of vehicles stopped at a junction and change timing of lights to see how it affects traffic flow
- decrease/increase traffic flow in all directions to see how traffic is affected
- try out impact of accidents
- consider passage of emergency vehicles
- Effect of adding in pedestrian crossings
- Once simulation is run, timing of the lights is determined and how they interact so that maximum traffic flow is achieved; fault scenarios (such as an accident) and their impact are considered
