We study the question of weak solvability for a nonlinear coupled parabolic system that models the evolution of the complex pedestrian flow. The main feature is that the flow is composed of a mix of densities of active and passive pedestrians that are moving with different velocities. We rely on special energy estimates and on the use a Schauder's fixed point argument to tackle the existence of solutions to our evolution problem.
