②The difference in the signal period of the signal lights at each intersection makes the timing of the green lights at adjacent intersections uncoordinated
③Because many roads cannot implement this kind of signal control system, there will be a large difference in the signal cycle between the connected intersections that have been implemented and those that have not been implemented, so that the vehicles at the intersection cannot be cleared during the green light time, or there will be vehicle sudden changes in a certain road section. increase, causing traffic jams or congestion
[0006] Due to the unscientific control of traffic signals and ineffective guidance, driving on urban roads frequently encounters red lights, resulting in a variety of hazards

Embodiment Construction
[0021] Below in conjunction with embodiment, the present invention is described in detail. The specific method steps are as follows:
[0022] 1. Set up traffic signal light devices at all relevant traffic intersections;
[0023] 2. Measure the distance between the upper and lower two adjacent intersection signal lights (each road section is the distance from the stop line of the upper and lower intersections in one direction, or the middle line of the upper and lower intersections), according to the actual situation of the road section , to accurately determine the appropriate driving speed for each road section distance and the driving time needed to travel from the green light at one intersection to the green light at the next intersection at this speed;
[0024] 3. Determine the relative direction of each intersection "the time from when the green light starts to turn on to when it goes out again" (referred to as "green light cycle"). , yellow light, red light, etc. until...

The invention relates to a method for designing the metropolitan region road traffic signal device which is characterized in that it uses the green light zero time of a cross to repetitively adds the green light period time; it uses the green light zero time to add the measuring running time needed by the cross to the next cross as the nest cross's green light zero time. It in order sets the green light zero time of each cross. It sets a traffic mark to display the best running speed of one cross to the next cross on the suitable position of the road to indicate the green light time of the next cross.
Description
technical field [0001] The invention relates to a design method of an urban road traffic signal device. Background technique [0002] In 1858, traffic lights were born on the main streets of London, England. Since then, urban road signal lights have become an important facility to guide traffic and maintain traffic order in cities all over the world. Red light stop, green light line is a traffic rule that every motor vehicle, bicycle and pedestrian must strictly abide by. At present, the setting of the lighting time of urban road traffic lights is unreasonable, which is manifested in: ①The setting of the lighting time of many red and green lights is not based on the overall situation of the whole city, and the lighting time of two adjacent signal lights lacks an inevitable connection. It is in a state of "doing its own thing" and "no appointment" when the lights are on. Like this, the red and green lights are constantly changing, but the traffic lights frequently run into...
