Taxi is an important means of transport in our life. With the development of the society, a taxi is convenient or not and its price may have a direct impact on the passenger's ride experience and the quality of life. There is no denying that it is necessary to discuss how to set prices, etc. In Model 1, we divide the whole city into four zones according to their functions .we establish the relation between average waiting time and taxi number based on the balance equation of supply and demand. According to the actual situation ,we calculate the minimum number of taxis, which satisfies the requests, is 127. In Model 2, we studied the conversion issue from zone-to-zone price to meter-based price. Single ride distances and the number of passing zones can be obtained by computer simulation. Using these data, we can calculate the single-pass income under the two pricing systems. What ́s more, the correctness of Model 2 is verified by Washington ́s real taxi price system. Finally, we develop suitable zone-to-zone price in this city, and work out the meter-based price is 200cent/mile.
