Urban Trip Requests Prediction: An Operator’s Perspective

Abstract— With the help of e-hailing apps, such as Uber, finding passengers is no longer a problem for drivers. Transportation network companies’ operators are concerned about how to allocate their cars in the urban area to maximize the company’s profit. To answer that question, they have to know how trip requests are distributed over time and regions. In this paper, we present Gaussian Mixture Experts (GME), to partition the city into multiple regions and estimate of the trip request density with fixed Gaussian components but time-variant weights. We utilize the periodicity to predict the trip requests by context filtering. Our method is tested on real industrial urban trip request data. The result shows that our method achieves a good approximation to the real condition.
