How and what data is gathered- Simulation

To make this as realistic as possible, data is required to be gathered over a long period of time. This can be done by sensors near/in the road, using cameras or manual data collection. Data gathered comprise:

-  count the number of vehicles passing in all directions at each junction .....

-  ..... At a particular time of day

-  count how many cars build up at a junction before lights change

-  is it a week day or bank holiday or weekend

-  How long it takes to clear vehicles at a junction

-  Other data (such as pedestrian crossings)

-  Time for largest/slowest vehicle to pass through a junction

-  Other factors (for example filtering of traffic to the right or left)
