ABSTRACT: The proper phase difference of traffic signals for
adjacent intersections could decrease the time of operational delay. Some theorems
show how to minimize the total average delay time for vehicle operating at adjacent
intersections under given conditions. If the distance and signal cycles of adjacent
intersections satisfy with specific conditions, the total average delay time would
achieve zero. If the signal cycles of adjacent intersections and the phase difference
of them are co-prime numbers, the total average delay time would be a constant.
In general, if signal cycles of adjacent intersections and the phase difference
of them are reducible numbers, the minimum total average delay time would be solved
by the given algorithm. Numerical experiments have verified the rationality of these
theorems.
