Delay< 10 seconds/vehicle Delay<10.0 seconds/vehicle B Vehicle progression is highly favorable or the cycle length Short traffic delays. is short. Delay> 10 seconds/vehicle and< 15 seconds/vehicle Delay>10 seconds/vehicle and<20 seconds/vehicle C Vehicle progression is favorable or the cycle length is Average traffic delays. moderate. Individual cycle failures may begin to appear at Delay> 15 seconds/vehicle and<25 seconds/vehicle this level. Delay>20 seconds/vehicle and<35 seconds/vehicle D Vehicle progression is ineffective or the cycle length is Long traffic delays. long.Many vehicles stop and the individual cycle failures Delay>25 seconds/vehicle and<35 seconds/vehicle are noticeable. Delay>35 seconds/vehicle and<55 seconds/vehicle E Vehicle progression is unfavorable and the cycle length is Very long traffic delays,failure,extreme congestion. long. Individual cycle failures are frequent. Delay>35 seconds/vehicle and<50 seconds/vehicle Delay>55 seconds/vehicle and<80 seconds/vehicle F Vehicle progression is very poor and the cycle length is Intersection blocked by external causes. long.Most cycles fail to clear the vehicle queue.
