Traffic Signal Timing
Dilemma Zone: Scenario 3 Page 151
The animated space-time diagram on the next page shows that driver started to brake but then change his/her mind and tries to go through the intersection.

Two curves are depicted:

  • The curve denoted by the continuous line shows the initial decision to brake and then the decision to accelerate and continue. This decision will result in a violation of the red light when the stop line is crossed.

  • The curve denoted by smaller dots shows the decision of braking and stopping comfortably before the stop line.
