Description

A motor vehicle parking line at a traffic intersection that expands the driver's field of vision

technical field

The utility model belongs to the technical field of traffic facilities, in particular to a motor vehicle parking line at a traffic intersection which expands the driver's field of vision.

Background technique

With the continuous improvement of the quality of life, there are many ways to travel, but the traffic accidents that follow are more and more frequent. According to statistics, in the past three years, there have been 14,000 traffic accidents involving motor vehicles and pedestrians on zebra crossings across the country. Among them, the main cause of the accident is that the right-turning vehicle does not see the pedestrian on the zebra crossing because the next car blocks the line of sight while waiting for the red light; and there is still no better solution to this problem.

SUMMARY OF THE INVENTION

For the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a motor vehicle parking line at a traffic intersection that expands the driver's field of vision, which can effectively expand the driver's field of vision. When waiting for a red light, drivers on the right-turn motorway can still clearly observe the flow of people at the zebra crossing.

In order to achieve the above purpose, the following technical solutions adopted by the present utility model are: a motor vehicle parking line at a traffic intersection that expands the driver's field of vision, a zebra crossing at the traffic crossing, and one side of the zebra crossing is a left-turn motor vehicle lane and a right-turn motor vehicle lane; Between the motor vehicle turning lane and the right turning motor vehicle lane is a straight motor vehicle lane; the front end of the right turning motor vehicle lane is the right turning motor vehicle lane parking line; there is an intersection b on the left side line of the right turning motor vehicle lane, and the original left turning motor vehicle lane parking line is The left end point a, there is an inclined parking line between the intersection point b and the left end point a.

The distance from the parking line of the right-turn motor vehicle lane to the zebra crossing is equal to the distance from the left end point a to the zebra crossing 1 .

The distance from the intersection b to the stop line of the right-turn vehicle lane is 1/2 the length of the vehicle body.

The length of the body is 3 meters to 6 meters.

The sloping stop line can effectively expand the driver's field of vision. When there are vehicles waiting for the red light in the straight motorway and the left-turn motorway, the driver on the right-turn motorway can still clearly observe the flow of people at the zebra crossing. ; It can effectively expand the driver's field of vision. When there are vehicles waiting for the red light in the straight motorway and the left-turn motorway, the driver on the right-turn motorway can still clearly observe the flow of people at the zebra crossing.

The beneficial effects of the present utility model are:

1) It effectively solves the problem of pedestrians and right-turning motor vehicles causing accidents due to insufficient vision of motor vehicles, and effectively improves the efficiency of traffic travel.

2) To plan this inclined parking line, the engineering quantity is small, the construction cost is low, and it is easy to popularize and use.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to Figure 1, a motor vehicle parking line at a traffic intersection that expands the driver's field of vision, a zebra crossing 1 at the traffic crossing, one side of the zebra crossing 1 is a left-turn motor vehicle lane 10 and a right-turn motor vehicle lane 5; Between the motor vehicle lanes 5 is a straight motor vehicle lane; the front end of the right-turn motor vehicle lane 5 is the right-turn motor vehicle lane parking line 2; there is an intersection b6 on the left line of the right-turn motor vehicle lane, and the left side of the original left-turn motor vehicle lane parking line 3 At the end point a8, an inclined stop line 7 is provided between the intersection point b6 and the left end point a8.

The distance from the parking line 2 of the right-turn motor vehicle lane to the zebra crossing 1 is equal to the distance from the left end point a8 to the zebra crossing 1 .

The distance from the intersection b6 to the stop line 2 of the right-turn vehicle lane is 1/2 the length of the vehicle body.

The length of the body is 3 meters to 6 meters. The body length can be any vehicle with less than nine seats as a reference, and its body length is 3 meters to 6 meters. A better choice is 4.8 meters, because most people buy vehicles with a body length of 4 meters to 5.5 meters in life.

The working principle of the utility model is:

This inclined stop line is suitable for any cross traffic intersection. You need to find the left end point a8 and the intersection point b6, and connect the two points into a line segment. Among them, the parking line of the right-turn motor vehicle lane is located on the parking line of the original motor vehicle lane, and the distance from the parking line of the right-turn motor vehicle lane to the zebra crossing at the traffic intersection is the distance from the left end point a8 of the upper left end of the left-turn motor vehicle lane parking line to the zebra crossing. Equal, the intersection point b6 of the straight motor vehicle lane-4 next to the right-turn motor vehicle lane and the right-turn motor vehicle lane line is 1/2 the length of the vehicle body from the parking line of the right-turn motor vehicle lane. At this time, the left end point a8 is connected to the intersection point b6. Form a sloping stop line. When both the left-turn motorway and the straight-line motorway are parked and waiting for the red light, the driver of the first vehicle on the right-turn motorway is 1/3 the length of the vehicle body from the parking line of the right-turn motorway. Therefore, it is possible to Clearly observed all the flow of people on the zebra crossing.

The left end point a8 is the intersection of the road center and the left-turn motorway parking line 3, that is, the point at the upper leftmost end of the left-turn motorway parking line, and the intersection b6 is the right-turn motorway line and the straight motorway. intersection.

The straight motor vehicle lane includes a straight motor vehicle lane 1 and a straight motor vehicle lane 2. The number of straight vehicle lanes is set according to the actual conditions of the road.

Referring to FIG. 2 , when there are vehicles waiting for the red light in the left-turn motor vehicle lane, the two straight motor vehicle lanes and the right-turn motor vehicle lane, and the right-turn lane does not need to wait for the red light, you can turn right. According to the survey, the length of vehicles with less than nine seats is less than or equal to 6m, the general vehicle length is about 4.8m, the distance between vehicles is generally 1m, and the distance between the parking line of the motor vehicle lane and the zebra crossing is generally 1m. Taking the general situation as an example, the following data can be obtained: the distance between the left end point a8 and the zebra crossing is 1m, the distance between the parking line of the right-turn motor vehicle lane and the zebra crossing is also 1m, the length of the vehicle is 4.8m, and the point b is from the right-turn motor vehicle lane. The distance of the parking line is 2.4m, and the distance between the driver's position and the parking line of the right-turn motorway is 1.6m. Therefore, when there are vehicles waiting for the red light in the left-turn motorway and the straight motorway, the driver of the first vehicle in the right-turn motorway can clearly observe the flow of people at the zebra crossing, and when the first vehicle leaves the stop line After that, the driver of the second car can clearly observe the flow of people at the zebra crossing.

Referring to FIG. 3 , it can be clearly observed that this new type of parking line is easy to implement and has strong practicability.

The design concept of the utility model is suitable for each T-shaped traffic intersection or cross traffic intersection. The design concept of the utility model is suitable for areas where motor vehicles drive on the right.
