Problems solved by technology

There is a problem in this system, that is, when the green light is on, the speed of the motor vehicles passing the stop line at the intersection is very low, and the time difference for the motor vehicles passing the stop line at the intersection is too large. vehicle time difference of up to 4.45 seconds (at a start time difference of 2 seconds), resulting in very low intersection capacity for motor vehicles

Embodiment 1

[0016] Embodiment one (see attached figure 1 ):

[0017] This embodiment is suitable for level intersections where the distance between intersections is less than 500 meters.

[0018] According to the above parameters, the leading distance of the leading parking line (5) can be set as v 2 / (2a) meters, the front signal light (4) is arranged on the conspicuous position above the front stop line (5), and the lead time of turning on the green light of the front signal light (4) and the lead time of extinguishing are respectively set It is v / a second, v / (2a) second.

[0019] According to the above setting, when the green light of the front signal lamp (4) was on, the time spent by the first car from the front stop line (5) to the intersection stop line (3) was v / a seconds; when the first car When arriving at the intersection stop line (3), the green light of the intersection signal light (2) is also just in time, so the first car can just pass the intersection stop line (3) wit...

Embodiment 2

[0030] Embodiment two (see attached image 3 ):

[0031] This embodiment is mainly suitable for level intersections where the distance between intersections is greater than 600 meters.

[0032]In the single-signal control line motor vehicle traffic control system and in the first embodiment of the present invention, due to the difference in vehicle speed and the difference in the parking position when the motor vehicle starts walking, the motor vehicle (especially when passing through the intersection stop line (3) (when the green light just starts to light up) the time difference j of the motor vehicle is much higher than the time difference j when the motor vehicle starts, and this unnecessary excessive time difference reduces the crossing capacity of the motor vehicle. In order to eliminate this unnecessary excessive time difference, the lead distance of the front stop line (5), the turn-on lead time of the green light of the front signal lamp (4), and the turn-off lead ti...

Abstract

The invention belongs to the technical field of traffic, and provides a motor vehicle traffic control system which is mainly applied to a plane crossroad. The motor vehicle traffic control system is characterized in that a prepositioned stop line and a prepositioned signal lamp are additionally arranged before an existing crossroad stop line and an existing crossroad signal lamp. With linkage control of the prepositioned signal lamp and the crossroad signal lamp by a signal controlling machine, a crossroad green wave band is generated around the periphery of the crossroad so that passing capability of motor vehicles at the crossroad is enhanced.

Description

Technical field [0001] The invention belongs to the technical field of traffic and is mainly used for motor vehicle traffic control at level intersections. technical background [0002] At present, many viaducts and overpasses have been built on the main roads of many large and medium-sized cities, and relatively advanced green wave belt traffic control technology has been adopted. Although it has played a major role in the smooth flow of urban traffic, urban traffic congestion is still a very serious problem. One of the main reasons is that the motor vehicle traffic capacity of level intersections is too low. The low traffic capacity of motor vehicles at level intersections leads to low vehicle speed in the urban green wave belt, and the slow diversion of fleets on the elevated road reduces the speed of vehicles on the elevated road, thus restricting the smooth traffic of the entire urban road network. [0003] The existing motor vehicle traffic control system at level int...
