| Abstract: | The higher level renovation project of road network is affected by the route pass through the dif ferent administrative regions, the topography and geological conditions along the highway. Given this, the paper puts forward the piecewise design concept. Based on the operation security of highway, it calculates and analyzes the pieeewise design speed and proposes the reasonable design speed for different piecewise condition. |
| Keywords: | road network routes piecewise design design speed operation speed |
