| Through the comparative study of CBD’s
road designs in China and abroad, this research
focuses on the differences of road section design
and intersection design. Combining relevant data
of available practices in the USA, Japan and China,
it suggests reduce the width of each motor vehicle
lane and changing the road corners from cutting
angle into right, in the hope to increase the service
efficiency of domestic CBDs’ roads and decrease
the waste of land resources resulted from the
regulation of road design |
| Key words: CBD, Width of motor vehicle lane, Intersection |
