ABSTRACT
This driving test was carried in typical grassland summer. The experimental section is the provincial road S101, a typical grassland highway located in Xilinhot city from Saihan town to Mandula town, Inner Mongolia, which is designed as a secondary road whose designed vehicle speed is 80 km/h[3]. Compared with other roads, this section has the features of low gradient, simple linear structure, less traffic flow and monotonous surrounding scenery. As it is, this section of highway is relatively representative.
