Abstract

The utility model discloses a dynamic traffic signal time interval distributing device, which comprises a plurality of vehicle amount information acquiring units, a central processing unit and a traffic signal lamp, wherein the plurality of vehicle amount information acquiring units are arranged outside intersection stop lines and on driveways which drive to the intersection, the central processing unit receives the information from the vehicle amount information acquiring units, and the traffic signal lamp is electrically connected with the output end of the central processing unit and is arranged on a signal lamp bracket of the intersection. The time interval distributing device has the benefits that the plurality of vehicle amount information acquiring units are distributed on each driveway, can acquire the vehicle amount information, and can transmit the vehicle amount information to the central processing unit; the central processing unit processes the information to judge the vehicle amount on each driveway, and automatically adjusts the work time of the traffic signal lamp according to the size of the vehicle amount, thereby achieving the aim of immediately adjusting the work time of the traffic signal lamp according to the size of the vehicle amount, immediately and effectively getting the road traffic on the move again, making full use of the existing traffic resource, and greatly improving the vehicle running efficiency.

Description

Assignment apparatus of dynamic traffic signal time-intervals

Technical field

The utility model relates to a kind of device of controlling traffic lights work.

Background technology

At present traffic intersection all is to adopt red, yellow, the green three look traffic lights flow direction that directs traffic, and generally all is the employing timing controlled, and promptly the conduction time of red light, amber light, green light or power-off time all have the regular time section.Sometimes also can adjust the energising or the power-off time of signal lamp according to the vehicle flowrate peak period of upper and lower class, to reach the purpose of regulating vehicle flowrate, avoiding the jams, but this adjustment generally is to adopt manual adjustment to be installed in the interior timing unit of signal lamp bracket bottom control box, or the timing data in the central manager of manual adjustment traffic control center realizes.This adjustment can not make the energising or the real-time adaptations of power-off time of traffic lights, and each is a random variation to current wagon flow on the road, sometimes the timing of signal lamp exists than big-difference with the vehicle pass-through actual conditions of reality, when particularly the traffic main artery vehicle flowrate is big, very easily cause traffic congestion; And vehicle flowrate hour also causes the long wait hold-up time of driving vehicle, does not make full use of existing traffic resource, makes its performance best efficiency.

The utility model content

Technical problem to be solved in the utility model provides a kind of assignment apparatus of dynamic traffic signal time-intervals that can adjust the signal lamp working time according to the magnitude of traffic flow automatically.

For solving the problems of the technologies described above, the technical solution of the utility model is: assignment apparatus of dynamic traffic signal time-intervals comprises: the vehicle fleet size information acquisition unit is laid on the outer and track that travel to the crossing of crossing stop line;

Central processing unit receives the information of described vehicle fleet size information acquisition unit;

Traffic lights are electrically connected the output terminal of described central processing unit, are installed on the signal lamp bracket at crossing.

As a kind of improvement, described vehicle fleet size information acquisition unit comprises and is installed in the pressure sensor that is used to detect vehicle fleet size under the road surface.

Owing to adopted technique scheme, assignment apparatus of dynamic traffic signal time-intervals comprises: the vehicle fleet size information acquisition unit is laid on the outer and track that travel to the crossing of crossing stop line; Central processing unit receives the information of described vehicle fleet size information acquisition unit; Traffic lights are electrically connected the output terminal of described central processing unit, are installed on the signal lamp bracket at crossing.The beneficial effects of the utility model are: the vehicle fleet size information acquisition unit is set to a plurality of and is distributed on every runway, it can implement the collection vehicle quantity information, and with information transmission to central processing unit, central processing unit is by judging the vehicle flowrate size on every runway to information processing, and according to the automatic working time of adjusting traffic lights of the size of information of vehicle flowrate, to reach the purpose of adjusting the signal lamp working time according to road surface vehicle flowrate size at any time, at any time dredge road traffic effectively, make full use of existing traffic resource, increased substantially vehicle pass-through efficient.

Description of drawings

Fig. 1 is the mounting structure synoptic diagram of the utility model embodiment;

Fig. 2 is the structured flowchart of the utility model embodiment.

Embodiment

Shown in Fig. 1 and Fig. 2 are common, assignment apparatus of dynamic traffic signal time-intervals, comprise: the vehicle fleet size information acquisition unit, be laid on the outer and track that travel to the crossing of crossing stop line, be set to a plurality of and be evenly distributed under the road surface of every runway, so that can detect the vehicle fleet size information of whole road, the information acquisition unit of vehicle fleet size described in the present embodiment comprises and is installed in the pressure sensor 1 that is used to detect vehicle fleet size under the road surface, when vehicle ' is come, pressure sensor 1 will detect signal, and detected signal is sent out.

Present embodiment also comprises central processing unit (not showing among Fig. 1), receive the vehicle fleet size information that described vehicle fleet size information acquisition unit collects, general central processing unit is installed on the mounting bracket of traffic lights 2, be used to handle pressure sensor 1 detected signal, central processing unit inside is provided with time control circuit, be used to adjust the working time of traffic lights 2, time control circuit can automatically be adjusted the working time of traffic lights 2 according to the signal that pressure sensor 1 transmits, time control circuit is the known contents of those skilled in the art, here repeats no more.

Principle of the present utility model is to realize like this, on each passage on the four direction of intersection, pressure sensor is set respectively, at any time the vehicle flow information of transmitting on each passage is given central processing unit, how many central processing units judges the vehicle flowrate size according to the signal pulse that transmits on each passage, judge that decision postpones or the shortening right of way signal time, the open and close of traffic lights is foundation how much controlling of vehicle flow at that time like this, so can dredge road traffic at any time effectively, the fullest utilization has traffic resource now, increases substantially vehicle pass-through efficient.For tightening security, stay surge time in three seconds during the signal lamp conversion.

The utility model can be according to the size of road surface vehicle flowrate, automatically adjust the cycling time of traffic lights work, help to regulate at random passing through the time of road surface vehicle flowrate, prevent that vehicle flowrate from too much gathering or vehicle is waited for for a long time at the crossing, utilized traffic resource and control of traffic and road system fully.

Claims

1. assignment apparatus of dynamic traffic signal time-intervals is characterized in that, comprising:

The vehicle fleet size information acquisition unit is laid on the outer and track that travel to the crossing of crossing stop line;

2. assignment apparatus of dynamic traffic signal time-intervals as claimed in claim 1 is characterized in that: described vehicle fleet size information acquisition unit comprises and is installed in the pressure sensor that is used to detect vehicle fleet size under the road surface.
