A Research On Taxi Value Improvement

Taxi value comes from the function of vehicle and the attribution of economic behavior,which is of positive meanings to the life and activities of passengers and drivers.From the perspective of supply-demand integration,the taxi value not only includes the positive meanings that passengers obtained from handling their specific affairs after taking taxis from original addresses to destinations,but also includes the positive meanings that drivers obtained from fares after providing taxi services for passengers.In recent years,taxi plays an increasingly essential role in urban transportation while the problem of urban road traffic congestion has not been completely solved yet.Meanwhile,the wide application of intelligent transportation technology provides a new idea for the study of taxi value improvement,that is promoting taxi to create and achieve more positive meanings for more passengers and more drivers by intelligent transportation technologies.There are several theoretical significances in this study,including theory innovation significance,perspective innovation significance,method innovation significance and model innovation significance.And there are also several practical significances in this study,including popularizing intelligent transportation technologies,alleviating urban road traffic congestion,and promoting taxi value improvement.In Chapter 2,the author proposes Temporal Spatial Utility-based Value Analysis(TSUVA)model.Time-spaces are divided into specific time-spaces and continuous time-spaces.Temporal spatial utility is proposed on basis of Chinese utility,partially assimilating western utility and entirely integrating with timespaces,which is defined as the extent to which the object at a time-space has an influence on the subject at a time-space.Values are divided into potential values and accomplished values.Accomplished value is equal to the result that potential value multiplied by temporal spatial utility.Related contents have innovations in the research fields of utility theory,value theory,value analysis method,and value evaluation model.In Chapter 3,the author proposes the taxi value improvement mechanism based on TSUVA model and taxi actual situations,and then proposes several specific taxi value improvement pathways and approaches based on taxi value improvement mechanism and intelligent transportation technology applications.Passengers who take taxis for getting emergency medical treatments or catching flights are regarded as highpotential-value passengers.Drivers who are severe cash-strapped and run taxis for scratching livings are regarded as high-potential-value drivers.The average level of total taxi accomplished values is regarded as the target of taxi value improvement in this dissertation.Related contents have innovations in the research fields of the perspective of supply-demand integration,taxi value analysis method,taxi value calculation model,taxi value improvement pathway,and taxi value improvement approach.In Chapters 4-7,the author proposes several specific models based on taxi value improvement pathways and approaches,including Four-vertex Elevation Interpolation(FEI)model based on spherical coordinate system,Distance Calculation(DC)model based on spherical coordinate system without considering elevation,DC model based on two coordinate systems considering elevation,High-potential-value Subject Identification(HSI)model,and Motorcade Sharing(MS)model.Furthermore,those models above mentioned are applied to a large amount of original data,including elevation data in Google Map,taxi data in Sanya of China,taxi data in Zhengzhou of China,taxi data in Liaoyang of China,and taxi data in Haikou of China.As a result,the target of taxi value improvement is achieved.Related contents have innovations in the research fields of taxi value improvement method and taxi value improvement model.There are five main conclusions in this dissertation,which are listed as follows.First,TSUVA model is applicable to taxi value analysis.Second,taxi elevation calculation of high-efficiency has significant positive effect on taxi value improvement.Third,taxi distance calculation of high-efficiency has significant positive effect on taxi value improvement.Fourth,high-potential-value taxi subject identification of high-efficiency has significant positive effect on taxi value improvement.Fifth,taxi motorcade sharing of high-efficiency has significant positive effect on taxi value improvement.There are several future application prospects in this dissertation,including promoting taxi value improvement,facilitating taxi energy saving as well as emission reduction,and alleviating urban road traffic congestion.
