Abstract

The embodiment of the present invention discloses a method for extracting characteristic road sections, a method for judging dangerous road sections, and a system. The extraction method includes: using an inertial measuring instrument to measure the road to be tested, and obtaining the information of the road to be tested collected by the inertial measuring instrument. Attitude parameters corresponding to each continuous sampling point, wherein the installation surface of the inertial measuring instrument is parallel to the road surface of the road to be measured, the attitude parameters include: pitch angle and heading angle; according to the attitude parameters, determine the The shape parameters contained in the road to be tested, wherein the shape parameters include: vertical curve radius and flat curve radius; according to the shape parameters of the interval road sections included in the road to be tested, the characteristic road sections included in the road to be tested are extracted, wherein , the characteristic road section includes: a road section with a convex curve, a road section with a concave curve, a road section with a longitudinal slope, a road section with a left curve, a road section with a right curve and a straight road section. The embodiment of the present invention not only has high efficiency, but also has good stability.

Description

technical field [0001] The invention relates to the technical field of road detection, in particular to a method for extracting characteristic road sections, a method and system for judging dangerous road sections. Background technique [0002] The "Highway Safety Life Protection Project" requires safety testing of all grades of highways across the country. Among them, requirements are put forward for some characteristic road sections of the road. Including "straight line", "circular curve", "clothoid", "horizontal curve", "longitudinal slope", "slope length", "vertical curve" and so on. The evaluation indicators of these characteristic road sections are all related to the design speed. At present, in the fields of transportation, road inspection, and road safety inspection, there are usually several methods for measuring the characteristics of straight curves and flat curves of roads: querying according to construction drawings and measuring with total stations. Among th...
