| In recent years, as the oil crisis and environmental problems aggravate, various countries have sped up the research and development of gas-fueled vehicles, which have been widely used in the transportation industry of our country, for the extensive application and popularization of them can effectively help to solve the problems of shortage of petrol oil and environmental pollution. Sichuan Province is one of the provinces in our country to promote the use of gas-fueled vehicles from a very early period. The buses, taxies, sanitation trucks in most of the cities in Sichuan Province are gas-fueled vehicles. Meanwhile, a great number of gas stations have been built, forming a network. However, along with the escalation of the number of gas stations, the shortcomings of the existing network of gas stations emerge:single structure; lower efficiency; waste of resources; inefficient investment, etc. Therefore, in order to realize scientific planning of gas stations, an urgent problem to be solved by the designers and administrators of gas stations is how to establish a scientific planning theory for gas stations.Aiming at this problem, and in consideration of the network layout of the gas stations serving gas-fueled vehicles, this thesis analyses and researches the following problems:(1) It analyses the current condition of the construction of gas stations in Sichuan Province, and researches existing problems in this field.(2) It analyses and compares the current prediction methods for the number of gas-fueled vehicles, and selects the most optimized prediction method.(3) It studies the prediction methods for CNG, LNG and LCNG gas stations to build a prediction model for gas stations.(4) It predicts the demand of CNG, LNG and LCNG gas stations in Sichuan Province, so as to provide relevant government authorities and enterprises in the field with reference while planning for gas stations in the future. |
