Example 3
The embodiment of the utility model discloses pedestrian crosses street laser warning system. In the case of insufficient line of sight, the system comprises: laser lamp pole, pedestrian warns controlling means, pedestrian detection device, vehicle warning device. The following describes a road scene to which the pedestrian crossing laser warning system is applied. The method specifically comprises the following steps:
when the pedestrian crossing laser warning system is applied to pedestrian crosswalks of urban branches, the pedestrian flow is large and the demand of crossing zebra crossing is high because most of the two sides of the roads are living areas. At night, the speed of the motor vehicle is increased, the sight line of a driver is easily influenced, and particularly under the conditions of light interference of opposite vehicles and rain and fog weather, the difficulty of identifying pedestrians by the motor vehicle driver is increased, and traffic accidents are easy to happen. Therefore, it is necessary to arrange vehicle warning devices on two sides of the urban branch near the pedestrian crossing, and to control the vehicle warning devices to project stereoscopic warning information to the road surface by checking the pedestrian crossing information and according to the pedestrian crossing information, and when the starting condition of the vehicle warning devices is met, the vehicle warning devices project stereoscopic warning slogans, such as 'slow down' on the driving lane. To indicate that the vehicles coming and going need to pay attention to the current running speed. In addition, when the vehicle is detected by vehicle detection, the pedestrian detection device also detects pedestrians about to pass through the pedestrian crossing, and then controls the laser lamp post to project laser light. Wherein laser lamp pole and pedestrian detection device install in pedestrian's crosswalk both sides diagonal department, and when the pedestrian passed through the zebra crossing, pedestrian detection device detected the pedestrian, and the laser lamp pole sends red laser line for remind vehicle or pedestrian, notice safe current, thereby effectively promote the visual early warning distance of driver.
When the laser warning system for the pedestrians to cross the street is applied to the roads with more lanes or safety islands, because the speed of the roads is higher, the time for the pedestrians to pass through the zebra crossing is longer, and the probability of accidents is higher. Therefore handle and need install vehicle warning device and install laser lamp pole and pedestrian detection device respectively in the road both sides of predetermineeing the place at pedestrian crossing, and also will install laser lamp pole and pedestrian detection device respectively in the middle of the road or the both ends of safety island, when the pedestrian moves towards the road in the middle of the road or moves towards road another side in the middle of the road from road one side, thereby laser lamp pole and pedestrian detection device of corresponding road will get into operating condition and effectively promote the visual early warning distance of driver.
When the laser warning system for the pedestrians crossing the street is applied to suburb roads, the pedestrian flow is low due to insufficient night illumination of the suburb roads, and signal lamps are not generally arranged. At night, when pedestrians pass through the zebra crossing, potential safety hazards are prominent. Therefore, the laser lamp posts, the pedestrian detection device, the vehicle warning device and the pedestrian warning control device are arranged on the suburban roads and the pedestrian crossroads, so that drivers can find pedestrians in time through laser warning or laser lines, and traffic accidents are avoided.
When the laser warning system for the pedestrians to cross the street is applied to intersections between national provinces and roads along the street, the national provinces cross villages and town roads along the street, and a plurality of intersections are formed between the national provinces and the roads along the street. Because villagers are weak in traffic safety awareness, motor vehicles are high in running speed, no traffic signal lamp is arranged, hidden dangers of pedestrians and non-motor vehicles passing through pedestrian crossings are prominent, and traffic safety situations are severe, laser lamp posts, pedestrian detection devices, vehicle warning devices and pedestrian warning control devices are arranged on running lanes and pedestrian crossings at intersections of national and provincial roads and along-line branch roads, when pedestrians and non-motor vehicles pass through the pedestrian crossings, red laser lines are projected, remote warning is provided for motor vehicle drivers, and safety of the pedestrians and the non-motor vehicles is guaranteed.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
