1. Timing timing design content
single intersection traffic signal timing design content shall be included to determine more sections of signal timing, timing period during the design of the traffic volume, the initial trial cycle length and the traffic signal phase Signal phase is alternating current (ac) at any time the status of physical quantities. 】 Scheme, the signal cycle time, the phase signal timing than the green letter Green letter than a cycle refers to the traffic light can be used for the proportion of traffic time. 】 Review the service level, appraise and map signal timing, etc.
2。 Time division
timing single intersection traffic signal lamp on timing should be used according to the time varying regularity of traffic every day more sections of signal timing. If segmented according to actual situation from the early peak time, peak time, late in the afternoon rush hour, slack in the morning and at night time, noon slack time and generally flat peak period in each period. Each period signal timing plan, according to the prescribed design traffic volume of different times are calculated respectively.
3。 Design traffic
the design of traffic signal timing design, is to be prepared in accordance with the import different each time intersection signal timing to determine respectively. The different flow to the design of the traffic intersection each import shall take: that is, the timing time of peak hour 15 minutes of the highest flow rate' Flow rate of Annual runoff rate total Annual surface runoff water percentage of Annual precipitation, %) 。 】 Conversion of hour traffic.
4。 Phase letter street lamp factory was set
signal phase must import the driveway with intersection highly channelizing scheme set at the same time. And signal phase corresponds to turn around traffic volume and its layout lanes. 【 Launched by the traffic signal lamp post finishing above 】
