Embodiment 1

[0039] This embodiment provides a method for measuring the traffic volume and lane coefficient of the operating highway section, including:

[0040] The laser rangefinder is used to continuously collect section distance data, and at the same time, the collected section distance data is transmitted to the computer for storage in real time;

[0041] Carry out statistical analysis on the section distance to obtain the number of vehicles passing through the section to be measured and the passing position, and obtain the traffic volume and lane coefficient of the section;

[0042] The laser range finder is respectively erected on both sides of the road section to be measured, the laser range finder at point A is set at the central divider, and the laser range finder at point B is set at the hard shoulder or emergency parking lane;

[0043]The data acquisition frequency of the laser rangefinder is not less than 3 times per second, and the laser rangefinder has a wireless transmissio...

Abstract

The invention discloses a method for actually measuring the section traffic volume and lane coefficient of an operating road. The method comprises the following steps: continuously acquiring section distance data by using a laser range finder, transmitting the acquired data to a computer in real time for storage, and further performing data statistical analysis on the distance to obtain the number and passing positions of vehicles passing through a section to be measured; and thus calculating the section traffic volume and the lane coefficient. According to the invention, the computer is adopted to store and statistically analyze the numeric type data, so that the problems of large storage capacity of the traditional image type data and high difficulty of an image processing technology are solved. Besides, the actual measurement method involved in the technical scheme provided by the invention is high in operability, the data analysis method is simple and clear, the problems of complex model, cumbersome calculation and the like in the traditional section traffic volume statistical method are solved, and the actual application of engineering or related personnel is facilitated.

Description

technical field [0001] The invention relates to the technical field of traffic engineering, in particular to a method for actually measuring traffic volume and lane coefficient of a section of an operating highway. Background technique [0002] Traffic parameters, as an intuitive expression of highway operating conditions, are important indicators for highway traffic management, traffic planning, and regional economic analysis, and are also the most important basic data in pavement structure design. Whether the traffic parameters can be accurately determined based on the actual traffic conditions of road vehicles in operation is directly related to the rationality of traffic management and road network planning, and at the same time affects the accuracy of road surface structure design during road reconstruction, expansion, maintenance and repair. [0003] At present, in the survey of highway traffic volume and pavement structure design in China, "section traffic volume" and...
