So far, the highway in our more than25years of development history, the motorway network has been increasingly formation, the country has established a national and provincial level road network management center. In the evaluation of the operation of the regional highway network target the establishment of the system, a scientific evaluation mechanism, the establishment of a scientific and reasonable evaluation index system and method to promote the rational allocation of the highway network, and provide scientific scientific basis for the management and operation of the highway network.Departure from the linear network layout and operation of the status quo of the highway network, and the strengths and weaknesses of the existing evaluation index system and improved Finally, the evaluation index system suitable for the operation of the highway network. Indicators of the nature of the classification is divided into static metrics and dynamic indicators, the establishment of the two sets of evaluation index system, respectively, to take a different evaluation methods, the maximum degree of co-operation of the highway network status quo posted.Run a comprehensive evaluation methods are discussed in the highway network for dynamic indicators, the comprehensive evaluation method based on the three-dimensional dynamics of the timing, fully consider the impact of the time factor weights. Evaluation method for static data, discussed weight calculation method, including subjective weighting method and objective weighting method to take a combination of weight thinking. Static evaluation method based on the combined weight of DEA method in the comprehensive evaluation of the highway network.Finally, research the highway network of heavy fog, the fog on the roads, traffic capacity, the supply capacity of the road network, and control traffic incident heavy fog induced measures.
