| Abstract: | Depending on the reliability theory,the investment optimum model of road network is built,taking the integrated benefit of the road system as optimization objective and letting the investment of road construction as restriction condition.The construction project identified by this method are not only to realize the utilization of construction capital effectively but also to meet continual increasing traffic demand.In the end of the paper,an example is given to illustrate the practicability and feasibility of the method. |
