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
