Evaluation Study Of Comprehensive Transportation System In Urbanized Renovation Of Old Port

As the old port functions are diluting gradually and the existence of the old port is getting unsuitable with urban development and environment,some cities near the sea have began to try to carry on urbanized renovation of the old port and acquire some achievements.Since the old port usually lies in the central coastal zone and have a specifically historical and cultural significance,factors which influence urbanized renovation and contents which need reformed are excessive and complex in the process of urbanized renovation.Transportation system is a part of urbanized renovation about the old port.It could influence the achievements of urbanized renovation directly whether a suitable project has been chosen.Therefore,when different building projects of transportation system are evaluated,not only should factors evaluating general transportation system be considered,but also other factors such as the ecological environment,living conditions,history and culture should be put in the scope of comprehensive evaluation index through combining with characteristics and requirements of urbanized renovation.In this paper,the basic theories about urbanized renovation of the old port are elaborated and analyzed such as basic characteristics,programming principle and the influential factors.Then the theories are expanded to the issues of programming and building about the transportation system.Through the above analysis and according to the principles and ideas of selecting evaluation indexes,comprehensive evaluation index system is established which is used to evaluate the projects of transportation system programming in the process of urbanized renovation of the old port along the sea and river in China compatibly.The index system is designed into four levels and five aspects,including transportation functions,the regional natural environment,the living environment of human being,the history and culture and economy.Finally,35 representative indexes are concluded in all.On the basis,through the comparison of various evaluation methods,AHP and grey relativity theory are combined to establish the model(the model of A-G) which is suitable to evaluate the transportation system programming projects in the process of urbanized renovation of the old port. At last,different projects are evaluated in an example which urbanized renovation of the old Dalian port is used as according to the index system and the model established. it comes to the conclusion to prove the reasonableness of the selected indexes and the validity of the model.
