Modeling And Analysis Of Operation Characteristics Of Urban Natural Gas Taxis

In the current situation of energy shortage and serious air pollution,compared with traditional fuel vehicles,natural gas vehicles have the characteristics of environmental protection,energy saving,high economy,significant environmental benefits,and high technological maturity.They are becoming a major low-price industry..Carbon economy development.Based on the trajectory data of taxis,the relationship between residents’ travel rules,urban structural characteristics and energy consumption is discussed,providing guidance for the rational layout of taxis,optimizing the urban spatial layout,and improving the urban environment and transportation system.Based on the GPS data of Lanzhou taxis,the temporal and spatial distribution characteristics and carbon emissions of Lanzhou taxis are studied.First,a comprehensive data cleaning was performed on the original data.Due to equipment errors and human errors,the collected raw data cannot be used directly.Then,using spatial statistics and DBSCAN clustering methods,combined with map matching methods,spatial clustering of taxi data is performed,and the temporal and spatial structure and travel network of taxis are analyzed.Structure.The institute’s time and space rules for taxi operations in the area.Then,through the analysis of the nuclear density map,the obtained results are divided into four types of areas:high heat area,medium heat area,medium and low heat area and low heat area.By looking at the nuclear density maps on working days and non-working days,it can be seen that Lanzhou West Railway Station and Lanzhou Railway Station are important commuting nodes in the city and are located in the high-density passenger transport area.Any number of parts;for other hotspots,Lanzhou residents are different.Travel characteristics vary greatly at different times of the day.The passenger carrying situation at different times in the same area is different.Finally,based on the trajectory data of taxis,a carbon emission model of taxis was established,various pollutant emissions of taxis were evaluated,and the quantitative relationship between key characteristics and energy consumption was explored,thereby increasing the number of taxis.The load factor reduces the capacity of taxis.Pollution The things put...
