Mobile food business is a business which the venders use facilities like trucks and push carts to transport and sell food on streets or private properties. The mobile food business spreads out all over the San Francisco City, and the street-food becomes more and more popular today. To build and study the point process model on linear network is one of the most powerful ways to help us get the general idea of the spatial structure of mobile food facility locations in San Francisco City. This thesis is focused on forming point process data on linear network by using the information from the Internet and identifying the spatial structure of the mobile food facility locations based on K-function, pair correlation function, mark connection function, and point process model on linear network.
