Abstract:

With the goal of developing a resourceefficient traffic environment, this paper puts forward traffic performance evaluation system for highway ETC systems based on the principle of scientific, systematic and operability. It consideres the views of investors, managers and users and integrates the elements including vehicle travel speed, traffic delay, highway capacity, traffic safety, noise pollution and gas emission. Through a combined methodology of qualitative and quantitative research, it develops a system of quantified criteria for evaluation. Furthermore, it conducts extraperformance analyses on the ETC construction projects under various traffic flow conditions by applying the data envelopment analysis (DEA). This paper gives the ultraefficient quantized value of the ETC construction projects under different traffic conditions as an example. It also works out the relative ratio of the effective value corresponding to different traffic to find out the root causes of low efficiency and to propose corresponding measures.
