With the rapid development of China's economy, the road transportation network is also growing. In order to better understand the complexity of China's road traffic, this paper will analyze national road data, aiming to reveal the mystery of China's transportation network.
Let's talk about the data itself
Data Name: National Road Data.
Data format: shp
Data Geometry Type: Line.
Data coordinate system: WGS84
Data**: 1:1,000,000 public version of basic geographic information.
The total number of data is about 214,000;
Roads are divided into 15 categories, including national roads, provincial roads, county roads, township roads, village roads, urban roads, and rural roads, according to the standard of "Basic Geographic Information Element Classification and ** (GBT13923-2022)".
Some intercity highways have road codes, names, and grade attributes. (Compared with another road data, this data is more concise and clear, there are no redundant duplicate routes, that is, the same road is not divided into directions, and the classification method is divided according to national standards, but there will be more roads such as urban internal roads, non-motorized lanes, and greenways missing. ）
Through the analysis of national road data, it can be found that China's road traffic network has made remarkable achievements in terms of scale and development speed. Roads at different levels have played an important role in promoting economic development and improving people's livelihoods. However, with the development of the economy and the acceleration of urbanization, China's road transportation network still faces many challenges, such as traffic congestion, safety accidents and other problems. Therefore, it is necessary to further strengthen the construction and management of road traffic network in the future to improve the safety and efficiency of road traffic to meet the growing traffic demand.
In conclusion, national road data is an indispensable part of China's economic and social development. Through the analysis and study of these data, we can better understand the current situation and development trend of China's road transportation network, and provide strong support for future transportation planning and management.
