Research On The Highway Network Planning After Appraises Method

Along with Our country highway network construction unceasingly advancing, the different level highway network planning gradually carried out, the actual highway construction environment already greatly changed. The former the highway network planning already can't scientifically instruct the direction of highway construction, so it must carry on the original highway network plan adjusting, From not only guaranteeing highway construction continuity, but also the highway traffic further adapting the social economy development demand, this all appears extremely essential. Before carrying on the highway network plan adjustment, we appraise the plan effect of the original highway network from after angle appraises, which is extremely vital significance for enhancing the rationality and the feasibility of the highway network plan, also is the beginning of highway network plan fundamental research at the new turn in 21st century in China.First, in the foundation of summarizing and analyzing the domestic and foreign after appraises theory, the paper proposes the after appraises concept of highway network plan, limits the after appraises content. At the same time, comparing the highway network plan after appraises with the item after appraises, it constructs the theory frame construction of the highway network plan after appraises.Second, the paper diagnosis different region and different level highway network plan, summarizes the common using targets in the highway network plan. According to the selection principle of the after appraises target, it constructs the initial the target system of the highway network plan after appraises. Optimizing the initial target system by the AHP method, after which it establishes the final appraisal target system..Third, the paper research on the highway network plan after appraises method.. It constructs the after appraises model based on the fuzzy appraisal law. It defines the evaluation criteria of the highway network plan after appraises, after which establishes the subordination function in the different sector. It divides into the younger more superior subordination function and the more greatly more superior subordination function.. Fourth, according to the target system and appraisal method of the highway network plan after appraises, it carries the after appraises on the highway network plan. The after appraises includes the highway network plan development forecast appraises, the development scale surveys appraises, the construction implementation arrangement appraises. After obtained the appraises conclusion, it carries on the reason analysis.Finally, the paper applies the study achievement in the Jiangsu Province skeleton line highway network plan after appraises.
