Area Induction and Cooperative Control Technology of Multi-lane Highway with Small Spacing Interchanges Section Based on MPC

The small spacing interchanges section is a critical segment of multi-lane highways, exerting a profound influence on traffic flow and safety throughout the entire highway system. The optimization problem of highway traffic flow is a nonlinear and time-dependent optimization problem, and model predictive control (MPC) can achieve a better optimization effect. The existing highway MPC is more inclined to optimize the travel time, lane occupancy, queue length, and so on, but lacks the optimization by taking the highway operation risk as the evaluation index. To fill this gap, this paper studies the mechanism of MPC-based regional induction and cooperative control of multi-lane highways with small spacing interchanges and develops a control method combining driving simulation and traffic simulation. Finally, four scenarios of the Guangzhou-Shenzhen Highway are verified by simulation experiments. This study holds promise for informing decision-making processes and enhancing the design and management of highway systems in the future.
