特大城市交通信息化评价指标体系构建与实证研究——以北京市为例

An Evaluation Index System on the Informationization of Transportation in Mega Cities

根据交通信息化发展评价的内容和特点,从交通信息化基础设施建设、交通信息综合服务、交通信息化系统应用、交通信息化与交通运行、交通信息化标准建设等5个方面建立包含32项指标的特大城市交通信息化发展评价指标体系。基于熵权法对2001-2012年北京市交通信息化发展水平进行实证研究,结果表明:北京市交通信息化水平逐年上升,阶段化特征明显,从2001年的初始阶段迈入2012年的成熟阶段;同时呈现发展不平衡态势,系统应用发展迅速,标准政策发展相对滞后。

In terms of infrastructure construction,comprehensive information service,system application,traffic operation and standard construction of transportation field,this paper constructs the general evaluation index system on transportation informationization degree in mega cities.Based on the entropy weight method,it gives an empirical analysis based on the 2001-2012 statistical data in Beijing city. The results show an increasing of the whole level and positive phase characters and imbalance.It transfers from the initial phase in 2001 into maturity a stage in 2012.It develops rapidly in hardware systems but lacks the appropriate policies.
