What is the purpose of road calibration function?
1 Answers
Road calibration function mainly serves to inform and alert people. Below is a relevant introduction about the road calibration function: Location setting: Road traffic signs are usually set on the right side of the road, where drivers can easily see them. For lanes such as overtaking lanes, driving lanes, and emergency parking belts, road traffic signs are typically set above the road through gantries. Near the end of highways, some prohibition or warning signs are also placed within the central divider. The setting of road traffic signs for interchanges, service areas, etc., follows the principle that approaching traffic will not obstruct the driver's line of sight at intersections or points of divergence and convergence. Precautions: The placement of road traffic signs must ensure that drivers have sufficient reaction time to make necessary judgments for safe operation. Roadside traffic signs must maintain a clear distance of 250mm from the outer edge of the shoulder, and the lower edge of the signboard must have a clearance of 2000mm from the outer edge of the emergency parking belt. When setting signs above the road, ensure that the lower edge of the signboard maintains a clearance of more than 5000mm from the road surface. Road traffic signboards are generally set at a right angle to the road, with a slight inward tilt, and the front of the board faces the direction of travel for easy observation by drivers.
