Abstract:
In the 1950s, research on natural regionalization for highway was set out in China. This paper reviews its history and introduces
the relative research in other countries. Based on the comparative analysis of the different research angles among different
countries, suggestions about the future work are offered. The relations between physiographical indexes and the indexes directly
related with highway engineering are suggested to be studied and the basic data for highway be tested and collected all over
the country. These works will be of help to the guidance of regionalization for highway engineering. And the impact of highway
on the geographical environment should also be considered in highway natural regionalization.
