Traffic lights manufacturer about signal timing is mainly how to

Traffic lights manufacturer about traffic signal timing specifications, the main contents are as follows:

1, the timing plan

Punctual single intersection traffic signal timing plan content should include have concluded that many sections of signal timing period to distinguish, distribution planning and traffic volume, the initial trial period when the cycle time and traffic signal phase plan, signal cycle length, the phase signal timing, appraise evaluation of service level and make signal timing diagram, etc.

2, time to distinguish between

Punctuality single intersection traffic lights in the match should be according to the time-varying traffic everyday use more sections of signal timing. If segment according to actual situation from the early peak, peak in the afternoon and evening peak time, slack in the morning and at night time, noon slack time and usually flat peak time choice in each period. Each period signal timing plan, according to the different period of time prescribed in the planning of traffic separation.

3, planning and traffic

The traffic volume of the signal timing plans for, you must according to each match period when the intersection is not the same as the import way to conclude that separation. Each import way is not the same as the intersection traffic flow planning must take: that is, the timing time of peak hour 15 minutes of the highest hourly volume flow rate conversion.

4 and the traffic signal phase setting

Signal phase is necessary to import the driveway with intersection highly channelizing (i.e., lane function distinguish) plan set together. And turn signal phase to corresponding to the mercy of traffic volume and the lanes.
