Research On Optimization Model Of Taxi-Carpooling Expenses Based On Passengers’ Personalized Demand

Taxi is an organic part of the urban traffic system, but the empty running state always happen in the off-peak because of the high price and the asymmetric information between the drivers and passengers. And as for only a passenger in the taxi in the peak, waste of resources is serious. With the rapid growth Chinese economy and the quality of life to improve,residents demand for trip quality is constantly improving. But the average load rate of taxi is low, and the defect which per capital road occupation of large area always exist. Without changing the road traffic conditions, and not to reduce the income of taxi drivers, even could make the personalized needs of passengers are met and the per capital costs to the minimum.The model of taxi share-ride can solve this problem effectively.Since the eighty’s of last century, foreign scholars began to study the taxi share-ride.Europe and the United States have recognized the taxi share-ride as a reducing traffic congestion measures. Presently, domestic scholars’ researches mainly involve the basic theory of taxi share-ride, as the development status and trends of taxi share-ride, the organization mode and so on. Their researches are qualitative analysis basically. There are also some researchers to do the quantitative analysis. They have conducted the research to the path chosen of taxi share-ride chiefly. But for cost, calculation methods mostly adopt favors the interests of taxi drivers. For passengers, consider less or lack of consideration in the benefits. Very few scholars study the influence between passengers’ demand for personalized service quality and the cost.With the development of science and technology and the improvement of people’s living standard, the demand of taxi passengers is becoming more and more rich and personalized. It is the change of passenger demand that prompted the personalized service way, such as the taxi mobile phone software. Recently, the taxi software has come into being and spread rapidly in China, becoming the essential software in phone. However, there exists many disadvantages such as business ethics and vicious competition.According to the analysis of the taxi passengers’ need which is increasingly rich and personalized, the service content conforming to the passengers preference is formed.Combined with the new mode of taxi booking of mobile phone software, passengers can customize the way to travel according to their own needs and interests. Through to establish the Optimization model of Taxi-Carpooling Expenses Based on Passengers’ Personalized Demand could reduce the passenger travel cost, control the city taxi amounts, improve the transport efficiency of taxi in the peak time and ease the traffic congestion.Facing the widely popular mobile phone software for taxi and the increasingly rich passengers’ personalized demand, the optimization model of Taxi-Carpooling is establishedwhich based on the passengers’ preference, taking both taxi-drivers and passengers’ benefits into fully consideration.Based on the degree of satisfaction that passengers would pay for their own share, the model is made with the objective function aiming at maximum degree of satisfaction and minimum consumption of money. In view of its features, the theoretical model is further developed comparing the expenses in theory with that under existing conditions. The results show that this model can meet the need of both passengers and taxi drivers.
