The role of the contour marker, the contour mark is divided into several kinds, I want to be detaile

The contour mark is used on the highway and the first-class highway effect is obvious, the vehicle driving speed is faster, and the vehicle is in the process of driving at night, the visual distance is shorter, so that the safety of driving will be greatly reduced, so in order to achieve the purpose of safe driving, the linear indication in front of the highway is very important. The contour mark can make the driver understand the road conditions ahead in advance through the reflection of the car lights; The contour mark that is set on both sides of the road as the warning sign of the roadway boundary can also play the role of night induction, warning the driver, well ensure that the driving safety contour mark of the passing vehicle is mainly used for guardrails, side walls, tunnels and high-speed bridges, circuitous roads, etc., play the role of reminder and warning. 2.

The contour markers are firmly fixed to the corrugated guardrail.

, the reflected light at night is uniform and not dazzling, which plays a role in inducing and warning the driver to drive in the correct direction. 3.The role of contour markings is especially prominent in curves, mountain roads and bend-prone areas, which can greatly reduce the occurrence of traffic accidents and ensure the safety of vehicle traffic.

Although the contour mark accounts for a small proportion of traffic safety facilities, its role cannot be ignored. Especially on the highway and the first-class highway, the vehicle travels faster, and the vehicle is in the process of driving at night, the visual distance is shorter, which will greatly reduce the safety of driving, so in order to achieve the purpose of safe driving, the linear indication in front of the highway is very important. And the continuous setting of the contour mark is one of the effective means, and the contour mark can make the driver understand the road conditions ahead in advance through the reflection of the automobile light; The contour mark set on both sides of the road is used as a warning sign of the roadway boundary, and can also play the role of night guidance and warning driver, and the driving safety of passing vehicles is well guaranteed.

It can be divided into:

1.Rectangular contour mark Specification: 180x40mm (optional double-sided single-sided, double-sided, or single-sided single-sided).

Specification: 180x40 (single stick and single side).

3.Trapezoidal contour mark specification: 120x50x70mm (optional double-sided single-sided, double-sided, or single-sided single-sided).

4.Column contour marker, size: 130x130x100x1250 (optional double-sided, single-sided).

5.Sheet contour marker, size: 110x1100 110x1300 (optional plastic, steel plate).

The reflective lens is made of acrylic material, which has a long service life and good reflective properties. Uses: Widely used in highways, tunnels, bridges, circuitous roads and other roadside signs, can be firmly fixed on the corrugated guardrail, reflect the light evenly at night, not dazzling, play a role in inducing the driver to drive in the correct direction, especially in the curves, mountain roads and bend areas play a more prominent role, can greatly reduce the occurrence of traffic accidents.

The English name of the contour mark is delineator, which is set along the edge of both sides of the road, used to display the road boundary contour, guide the normal driving of the vehicle, and has a kind of traffic safety facility with retroreflective performance. According to its different setting conditions, it can be divided into two categories: independent contour mark and attached contour marker. When there is no structure on the roadside, the contour is marked as a column, which is composed of a column and an anti-reflector, which is independently arranged in the roadside dirt shoulder, and its main structure is a triangular cross-sectional column; When there is a structure on the roadside, the contour is marked as attached and consists of retroreflectors, brackets, and connectors.

Depending on the structure, contour markers can be attached to corrugated beam guardrails, concrete guardrails, tunnel side walls and cable railings.
