  • Construct and write a sequence allowing traffic to flow north/south, then east/west including filters so that traffic coming from each direction has the chance to turn right. Try to keep the queues of cars down by altering the time for each phase of the traffic lights.

Extension Task

To be completed if instructed by your teacher.

Construct a more efficient control sequence that, with two lanes of traffic in each direction, minimises queuing and waiting times. Consider in which directions traffic can flow at the same time. Record the sequence in your jotter along with a description of why your sequence is more efficient than those in Tasks 1 or 2.
