This paper studies heterogeneous traffic flow that comprises two types of vehicles with different lengths at a single intersection consisting of two perpendicular one-lane roads. Based on theoretical analysis and computer simulations, we have presented the phase diagrams which consist of five regions and the topological structure of which is independent of the maximum velocity of vehicles m. The analytical formulas of the flows on the two roads have been obtained in all regions of the phase diagram, which depends on whether m is even or odd or m = 1. The analytical formulas are in good agreement with simulation results.
