Urban traffic system is typical hybrid system. It is very difficult to coordinate the freeway off-ramp metering and downstream intersection signals which mean a special continuous-discrete-mixing traffic control model need to be considered. In this paper, taking queue length as continuous state variable, traffic signal as discrete variable and traffic count as continuous variable, Model Logic Dynamic approach is built for modeling. Then MILP optimization approach is applied to verify the rationality of the hybrid model. MATLAB simulation results show the MLD model and MILP based MPC method could be used for the coordination between off-ramp metering and downstream intersection signal very well.
