Eliminating intersection bottlenecks is one of the most persistent and difficult challenges for traffic engineers. A new mathematical theory called max-pressure (MP) signal control has been proven to achieve maximum throughput for entire city road networks, but it has not yet been used in practice.
This webinar will highlight LRRB research that’s bringing the theory several steps closer to real-world use. Hear from Prof. Michael Levin and Prof. Raphael Stern with the University of Minnesota and Ben Hao with Hennepin County about their work. It has involved adapting the MP mathematical model to address some practical issues, including the lack of a signal cycle. The research team also partnered with Hennepin County to test the model on seven intersections, and their results indicated reduced environmental impacts, reduced road user costs, and other potential benefits.
They will also share how they are working to implement MP control in traffic signal technology currently used in Hennepin County, laying the groundwork for a future pilot test of the method.
