The natural defects of the plane roads restrict the further development of traffic in Haikou and bring inconvenience to people’s life. Combining with the actual situation of Haikou, feasible measures are proposed for the urban road plane, section and intersection. After the linear programming model is appraised, the optimized scheme is reasonable and the traffic capacity of the road is improved.
