Four-phase intersection traffic control based on mixed logical dynamical modeling and predictive control approach

The urban population is increasing continuously, thus the importance of urban traffic control has greatly increased. One of the major issues in urban traffic control is intersections traffic control. At the intersection traffic control systems, continuous variables such as flow, queue length, average speed and discrete variables such as intersection light switching are exist. The MLD model can consider relationship between discrete variables and continuous variables. It provides a linear model from variables that is good to optimize in MPC framework. In this paper, MLD model as a class of hybrid systems used to model intersection traffic control. Then predictive control approach based on MIQP optimization is used to verify the rationality of MLD model. The results of MATLAB simulation show that MLD model with predictive control method can improve intersection traffic control.
