TRAFFIC_SIMULATION
Simulate Traffic at a Light

TRAFFIC_SIMULATION is a MATLAB program which simulates the way cars must wait at a traffic light.

The user can only input the number of 10-second time periods to be simulated.

The program operates with the following internal parameters:

• GREEN, the number of 10-second time periods that a green light lasts, set to 2.
• P, the probability that a new car will come to the light in the next second, set to 0.3.
• PERIOD_LENGTH, the number of seconds in one time period, set to 10.
• RED, the number of 10-second time periods that a red light lasts, set to 4.

Usage:

traffic_simulation ( n )

• n is the number of 10-second time cycles.
