Embodiment 1

[0037] The safety warning method for the widened area inside the small-radius curve of the road includes the following steps: the first step is to set out the line to determine the widened area of ​​the small-radius curve: within the area inside the curve with a road radius ≤ 250 meters, within the distance from the outside of the curve The edge line of the roadway is marked on the inner road surface of a lane width. The lane width is 3.5 meters wide according to the road grade, and forms a closed area with the edge line of the right side of the roadway, which is the widening area of ​​the small-radius curve.

[0038] After determining the widening area of ​​the small-radius curve, clean the road surface in the widening area of ​​the small-radius curve. The cleaning area is 2 meters wider than the construction area, and the road surface in the widening area of ​​the small-radius curve is cleaned. Dust, silt and moisture on the road surface are the main factors hindering the adh...

Embodiment 2

[0046] The safety warning method for the widened area inside the small-radius curve of the road includes the following steps: the first step is to set out the line to determine the widened area of ​​the small-radius curve: in the curve area with a road radius ≤ 250 meters, drive on the outside of the curve The edge line of the road is marked on the inner road surface of one lane width. The lane width is 3.75 meters wide according to the road grade, and forms a closed area with the edge line of the right side of the roadway, which is the widening area of ​​the small-radius curve;

[0047] After determining the widening area of ​​the small-radius curve, clean the road surface in the widening area of ​​the small-radius curve. The cleaning area is 2 meters wider than the construction area, and the road surface in the widening area of ​​the small-radius curve is cleaned. Dust, silt and moisture on the road surface are the main factors hindering the adhesion of the paint, which can b...

Abstract

The invention relates to a warning method for a widened area on the inner side of a small-radius curve to improve road safety. Firstly, the widened area of the small-radius curve is divided by setting out; secondly, the road surface of the widened area is colored and is paved with colored anti-slip materials; thirdly, marked lines are coated on the road surface of the widened area, an edge line of a roadway on the inner side of the widened area is covered with yellow solid marked lines, the outer side of the widened area is painted with white dotted marked lines, zebra crossings and vehicle stop lines in the widened area are normally constructed, and other portions of the inner side of the widened area are marked with oblique lines or serrated white marked lines; and finally, warning signs are arranged on a sidewalk or a green belt on the inner side of the widened area, and curve pedestrian warning sign layers are arranged on double surfaces of each warning sign. By the aid of the marked lines arranged on the widened area and the signs arranged on the sidewalk or the green belt on the inner side of the widened area on the inner side of the small-radius curve, safety of pedestrians, bicycles and motorcycles passing through the widened area on the inner side of the small-radius curve is improved.

Description

technical field [0001] The invention relates to a method for improving the safety of a small-radius curve widening area, a method for setting marking lines and signs in the small-radius curve area to improve road safety, and a safety warning method for the road small-radius curve inner widening area. Background technique [0002] Traffic accidents often occur when large vehicles turn right, resulting in a large amount of loss of life and property. Searching on Google with the keyword "large vehicle turning right, car accident", there are about 92,100 search results. For example, the "China Shanghai" website reported "Traffic Police Reminder: Large Vehicles Turning Right Turns Repeatedly Killing Cyclists, Riders Need to Raise Safety Awareness"; Fenghuang.com reported "Construction Vehicle Turned Right, Runs Over Woman Cyclist"; Today Morning Post reported "Fatal A right-turning pair of mother and child died under the wheel"; Driving Auto Network reported "Large vehicles caus...
