According to the notice (number 2018, 27) issued by the department of transportation about the adjustment of the national highway network name number, the provinces need to unify and standardize the national highway route names and numbers. Due to the development of road construction, the mileage of the road is changed, and the mileage of the road needs to be confirmed again. The former pile number setting is to obtain the pile number of the middle point of each route by inputting the starting pile number and the ending pile number of the road and interpolating according to the length and the mileage range of the route. And (5) according to the length average interpolation, obtaining the stake number of each point. However, the milepost number on the graph does not correspond to the actual length of the route, such as 1000 meters identified by the theoretical milepost, but the actual distance may be only 990 meters, and the road may be discontinuous, which may cause the actual location to be incorrect. When the mile pile is positioned, the anchor point is also positioned to improve the accuracy. The anchor points can be divided into control anchor points with higher precision and general anchor points. The accuracy of the control anchor point requires that the error in the maximum point position is not more than 50mm, and the set distance (density) is 10 km-15 km. The accuracy and density of anchor points in general is related to the specific application requirements and the surveying and setting method. In general, the mean error of the anchor points does not exceed 3m, and the distance is set to be 1 km-2 km. The measurement of the anchor point simultaneously comprises the measurement of pile number and coordinate information. Pile number acquisition is typically determined on site using tape measurements to measure the distance to the nearest milepost. The method for acquiring the coordinates of the anchoring points generally comprises four methods of GPS measurement, measurement from a digital map, measurement from a construction drawing and wire guide measurement.
The method is not suitable for the work of reconfirming the positions of the mileage piles, the mileage of the highway is greatly changed after years of maintenance and lane change, so that the terminal pile number before the road has a large deviation value, and a large amount of work is required for field workers to measure and correct the pile number before the road, so that some human errors are inevitable in the period. New methods are needed to make road milepost calculations.
