Description

An intelligent variable lane driving direction indicator sign

technical field

The utility model belongs to a road traffic sign, in particular to an intelligent variable lane driving direction indicator sign.

Background technique

The variable lane driving direction indicator sign is a kind of indicator sign set up with the variable guiding lane line to inform the variable lane driving direction and to instruct the lane users to choose the lane in the direction of the displayed guiding arrow. The existing variable lane direction indicator signs adopt the control strategy of setting the time interval of the variable lane change indication according to the historical traffic demand, which cannot dynamically adjust the lane change indication in real time, especially when the traffic demand is less than the lane direction change setting threshold. The pre-set lane direction indication scheme will lead to low utilization efficiency of variable lanes and inability to give full play to the traffic capacity of the variable lanes, and secondly induce traffic violations that do not follow the direction of the guiding lane. The existing variable lane driving direction signs often adopt the LED light band transformation in the traditional lane driving direction signs to display going straight or turning left (turning right). The display scheme is relatively fixed and the flexibility is poor.

Contents of the invention

The purpose of the invention of the utility model is to overcome the defects of the existing variable lane driving direction signs, and provide an intelligent variable lane driving direction indicating sign with wide application range.

In order to achieve the above purpose, the technical solution adopted by the utility model is: an intelligent variable lane driving direction indicator sign, comprising a lane driving direction sign main body, an LED lane driving direction arrow display screen arranged on the front of the lane driving direction sign main body , two front and back video vehicle detectors on both sides of the main body of the lane driving direction sign, the LED text prompt screen and the extended communication interface at the bottom of the main body of the lane driving direction sign, and the installation base and the electrical interface on the back of the main body of the lane driving direction sign , the front sides of the main body of the driving direction of the lane are provided with variable guiding lane lines and an intelligent controller inside, and the intelligent controller accepts the controlled lane flow, headway, and queuing length detected by the video vehicle detector After comprehensive comparison of the data, control the LED lane driving direction arrow display to display the corresponding direction arrow, so that the variable lane driving direction indicator sign can dynamically adjust the indicated lane driving direction according to real-time traffic demand, and cooperate with the corresponding text prompt on the text prompt screen at the bottom of the main body of the sign , can improve the traffic capacity and safety of the variable lane, and can also play an obvious indication and warning role; the extended communication interface can communicate with the intersection signal machine, and the control strategy can be coordinated with the signal timing; The power interface described above can also be connected with an external solar panel when the power supply condition is limited, so that the above-mentioned device has the advantages of energy saving and environmental protection.

The utility model adopts the LED lane driving direction arrow display screen embedded in the main body of the lane driving direction sign, which can display various schemes such as going straight, turning left, turning right, going straight left, going straight right, turning around, turning left and turning around, etc., and can adapt to various lanes The driving direction control scheme improves flexibility. The LED text prompt screen installed at the bottom of the main body of the lane driving direction sign can display corresponding text prompts, which can easily attract the driver's attention, and strengthen the visibility and warning of the variable lane driving direction.

detailed description

As shown in Figure 1, an intelligent variable lane driving direction indicator provided by the utility model includes a lane driving direction sign main body [1], an LED lane driving direction arrow display embedded in the front of the lane driving direction sign main body [1] screen [2], two front and back video vehicle detectors [3] on both sides of the main body of the lane driving direction sign [1], an LED text prompt screen [5] at the bottom of the main body of the lane driving direction sign [5] and an extended communication interface [8], The installation base [4] and the electrical interface [7] on the back of the main body in the driving direction of the lane, the variable guiding lane lines and the intelligent controller [ 6].

In Fig. 1, the intelligent controller [6] accepts the controlled lane traffic, headway distance and queuing length data detected by the video vehicle detector to give a control instruction after comprehensively comparing the left-turning lane and driving in the LED lane. The direction arrow display screen [2] shows the left-turn driving arrow, and simultaneously controls the LED text prompt screen [5] at the bottom of the lane driving direction sign main body [1] to show the left-turn lane. In the same way, the intelligent controller [6] can also control the LED lane driving direction arrow display screen [2] to display other driving direction arrows according to the data detected by the video vehicle detector, and simultaneously control the LED at the bottom of the lane driving direction sign main body [1] The text prompt screen [5] shows other text schemes, thereby reaches the purpose of intelligently changing the driving direction of the lane.
