¥For improved system efficiency, yellow interval timing should only be reduced to whatever level compliance can be maintained.
¥The yellow interval is for the time it takes a vehicle to
proceed or stop at the entrance to the intersection and
includes no time to clear it.
¥Thus the all-red phase must be adequate in length to assure that all conflicting traffic is held until even the slow
moving large vehicles can clear the intersectionÕs conflict points before cross traffic is given a green.
¥For safety, fair
laws, less pollution and more efficiency out of our roadways, engineering will always be the best solution for
all. There are no substitutes or short cuts.
