The Choice Decision Problem of Taxi Drivers in the Car Storage Pool of the Airport
Abstract:With the increase of citizens' income, passengers tend to take a taxi back to home after the flight. This article concentrates on the situation that a taxi driver is already in the airport, and there are two choices for him to optimize his income: choice A is to stay in the airport's parking lot and wait to pick up passengers back to city, choice B is to directly return and pick up passengers in the city. Choice A's profit comes from cab fare from airport to city, while choice B's profit is equal to the average profit multiplies time which is the same as time in the first choice. Take Beijing Capital International Airport for an example, we use web crawler to get flight information and collect data of taxis, and then predict the possible waiting time in choice A and passenger flow using Poisson distribution. We then use MATLAB to calculate our model using the data above and get the decision threshold, which is expressed as the number of waiting taxis just before the present one. Our article uses decision model to optimize the taxi driver's profit and provide an observable condition for him to decide.
