Profit assessment of the intercity transportation of CNG vehicles in Sichuan province and some proposals for promoting its practical application

Under the present situation of advocating energy saving and emission reduction, developing low carbon economy, and increasingly high oil dependency in China, CNG vehicles will run from within-the-city to intercity, which will be one of the most important way to relieve oil shortage, develop low-carbon transportation economy, and mitigate exhaust emissions. Through building evaluating indexes and evaluation index system concerning social, economic and environmental benefits, the principal component analytical method is adopted to make evaluation of the CNG vehicles transportation between cities in the pilot test area of Sichuan. The evaluation results exhibits social, economic and environmental advantages. In addition, this paper presents some proposals for promoting the CNG vehicles transportation between cities in the Sichuan area. (1) More CNG gas fueling stations should be constructed along the trunk roads; the related accident prevention regulations for the intercity CNG vehicle transportation should be formulated; and safety supervision should be highly focused on. (2) The intercity transportation of CNG vehicles should be backed by fiscal policy. (3) Key techniques involved in the CNG vehicles should be further studied and developed to improve safety and efficiency in the intercity transportation.
