Abstract

The utility model relates to an urban road network, which is designed based on existing chessboard-shaped urban roads namely normal roads. One-way express ways and normal roads are mutually crossed and arranged at intervals, and one-way express overpasses are arranged at crossing positions of the one-way express ways and the normal roads. The one-way express ways and the one-way express overpasses are adopted to improve traffic capacity of urban roads so as to distribute traffic pressure of the roads, the problem of urban traffic congestion is resolved, and travelling of people is facilitated. The urban road network has the advantages that when a person advances to a target place in any direction, rapid traffic can be realized by finding a one-way express way nearby, and oil saving can be achieved by selecting a nearest road. Adjacent one-way express ways have the same traffic capacity as an express highway and also have all functions of an urban road so as to be a perfect combination of the express highway and the normal road. The urban road network can be rebuilt on the existing roads, is low in investment, small in occupied area, simple in engineering and easy to implement while having more complete functions as compared with the express highway.
