Abstract:

We performed improved design of urban road intersection, taking the intersection of Yuhua Road and Tangu Street in Shijiazhuang as an example. We initially collected such original data as location, terrain and traffic volume of the intersection and then assessed operating conditions of the intersection traffic volume with Synchro simulation software. We further conducted widening design for crosssection and the intersection with the principle of least disturbance and some relevant intersection design specifications. The total delay time is reduced from 6.1 h to 2.7 h after the design, so intersection traffic congestion is effectively relieved.

Key words: intersection, graphic design, widening design
