Problems solved by technology

However, in the above method, it is necessary to widen a dedicated buffer lane to set the buffer zone, and it is difficult to have the conditions for selection in some urban roads
The self-sensing frequency conversion yellow flashing light warning device is only suitable for cross-shaped intersections, and there is a certain distance requirement for the buried geomagnetic induction device, so it is difficult to install such a warning device at small entrances and exits

Embodiment 1

[0031] see figure 1 , Figure 5, the invention discloses a deceleration warning system for main road entrances and exits, including a sensing unit, a comprehensive coordination control module and a deceleration warning unit, wherein: the sensing unit is composed of a community entrance and exit access control device or / and an infrared detector, and a vehicle steering detection device; the deceleration warning The unit includes a vehicle deceleration yellow flashing warning light set on the main road close to the driving direction of the residential area And set on the main road away from the direction of the community on the side of the vehicle deceleration yellow flashing warning lights ; The integrated coordination control module receives the access control device at the entrance and exit of the community Or / and the detection signal of the infrared detector and the vehicle steering detection device, judge the vehicle leaving the community to turn right or left, and outp...

Embodiment 2

[0033] see figure 2 (a), the deceleration warning system at the entrance and exit of the arterial road in this embodiment is different from that in Embodiment 1 in that: for the case where the access control device at the entrance and exit of the community has an access control for the exit and the entrance, the sensing unit obtains the vehicle status through the switch state of the exit access control. The departure signal is transmitted to the integrated coordination control module.

Embodiment 3

[0035] see figure 2 (b) The deceleration warning system at the entrance and exit of the main road in this embodiment is different from that in Embodiment 2 in that: the access control device at the entrance and exit of the community shares one access control for the exit and entrance, and two sets of infrared detectors are used to link with the access control device. Two sets of infrared rays The detectors are respectively arranged on the inner side and the outer side of the railing fixing device of the access control device. The infrared beams emitted by the two sets of infrared detectors are parallel to the crossbar of the access control device. The coverage of the two sets of infrared detectors is the same as the length of the crossbar of the access control device. When the inner infrared detector is blocked first and the outer infrared detector is blocked later, it indicates that a vehicle has left the community, otherwise, it indicates that a vehicle has entered the commu...

Abstract

The invention relates to a traffic signal control system, particularly to a deceleration warning system at a gateway of a trunk road. The deceleration warning system comprises an induction unit, an integrated coordination control module and a deceleration warning unit. The induction unit consist of a cell inlet-outlet access device, infrared detector, or/and a vehicle turning detection unit. The deceleration warning unit includes a vehicle deceleration yellow-flashing warning lamp (1) arranged at a place, approaching a driving direction of one side of a cell, of a trunk road and a vehicle deceleration yellow-flashing warning lamp (2) arranged at a place, far away from the driving direction of one side of the cell, of the trunk road. The integrated coordination control module receives detection signals from the cell inlet-outlet access device (4) or/and the infrared detector and the vehicle turning detection unit, determines right turning or left turning of a vehicle being driven out of the cell, and outputs a control signal to the deceleration warning unit, so that the vehicle deceleration yellow-flashing warning lamp (1) or the vehicle deceleration yellow-flashing warning lamps (1) and (2) works/work and thus a vehicle on the trunk rod to slow down. Therefore, a vehicle driven out of the cell can pass through an intersection rapidly and safely.

Description

technical field [0001] The invention relates to a traffic signal control system, in particular to a deceleration warning system for main road entrances and exits. Background technique [0002] At present, urban construction is changing with each passing day, high-grade roads are constantly being built, and urban construction is constantly advancing. Some residential quarters, small and medium-sized enterprises, and units facing the street / road (the following residential quarters are taken as examples) often open directly on one side of the main road to form a "T" intersection in order to meet their own convenient transportation. Since there are fewer vehicles coming out of the community, the conditions for setting signal lights cannot be met, and such intersections often have insufficient sight distances, so vehicles coming out of the community, especially at night, are easier to communicate with the main road. traffic accidents due to vehicle collisions. Vehicles at the e...
