Description

A data processing method for road test signal detection system of mountain expressway

technical field

The invention relates to the technical field of data collection and processing, in particular to a data processing method for a road test signal detection system of a mountainous expressway.

Background technique

With the rapid and comprehensive development of the economy, my country's expressway construction has made great achievements. my country's geographical environment is extremely rich. In order to speed up the traffic roads connecting different regions, many mountainous expressways have been built in our country. The road environment of mountainous highways is complex and accidents occur frequently. Chinese researchers often do some road tests to collect relevant data. In the research of road test data such as road safety evaluation, vehicle speed characteristics, adaptive cruise based on road alignment, etc., It is often necessary to collect and test signals such as vehicle speed, acceleration, and vehicle lateral acceleration on the road to obtain the signal corresponding to the road alignment stake number of the vehicle on the road, that is, to know each point of the corresponding stake number of the vehicle in the road alignment Signal. It is of great significance to clarify the relevant signals when the vehicle is at a certain station position of the road alignment.

At present, the existing road test collection methods can collect relevant vehicle signals and the corresponding longitude, latitude and elevation of the signals, but it is difficult to correspond the longitude, latitude and other position information corresponding to the collected relevant signals to the chainage of the road alignment However, the item of road stake number is not displayed in the data output item. The existing technology is to manually process the data after collecting the data, and use the collected position information such as longitude and latitude to manually map it to the relevant road alignment stake number. This method is not only not accurate, but also has a high efficiency of data processing. At the same time, due to the loss of GPS signals when collecting mountainous expressway tunnels, position signals such as latitude and longitude in the tunnel cannot be obtained, which will lead to the lack of data collection and bring great troubles to later research. Generally speaking, the road test signals collected in the prior art all use the longitude and latitude information to correspond the collected signals, and it is rare to use the road stake number information for correspondence.

Expressways in mountainous areas are obviously different from expressways in plain areas, and have some notable features. The height difference is very large. For example, the expressway from Xi'an to Hanzhong has an elevation difference of more than 1,000 meters. For this type of mountainous highway with a large elevation difference, we usually only need to know the elevation of a certain point on the road, and then we can easily obtain the road stake number corresponding to the elevation.
