2.3 Disadvantages
Traffic signals are sometimes considered problems at
intersections. In fact, traffic signals that are poorly located
can adversely affect the safety and efficiency of vehicle,
bicycle and pedestrian traffic. Improper or unjustified
signals can result in one or more of the following:
· Significant increase in the frequency of some types
of collisions
· Increased congestion, air pollution, and fuel
consumption.
· Excessive delay.
· Excessive disobedience of the signal indications.
· Increased use of less adequate streets as motorists
attempt to avoid the traffic signals.
· Frustration especially in hot weather.
