Science Under the Dome Lecture Series
Moving More Cars Through Smaller Spaces
Professor Joseph Hummer, Department of Civil and Environmental EngineeringWayne State University Traffic congestion is a terrible problem in Detroit and major cities worldwide. Congestion wastes time, causes collisions and injuries, wastes fuel, and adds harmful emissions to our atmosphere. In most US cities, the easy solutions to traffic congestion have already been implemented, and only expensive and disruptive choices like widening, bypasses, flyovers, and changing people's travel habits remain. Alternative designs of intersections and interchanges, where most of the congestion occurs, are a way forward that have gotten some attention and activity recently. The Michigan left turn, which is popular in the Detroit area, is an example of an alternative design. There are dozens of other alternatives. Most of the alternatives reroute left turns to simplify movements at the main junction, freeing green time for through vehicles and pedestrians. None of the alternatives is a universal solution, but each looks like it has a niche where it could be helpful. Dr. Hummer will show why alternative intersection and interchange designs have promise to relieve congestion. He will review the current menu of alternative designs and show some that have not been built yet but have promise for the future. In the end, he will provide a vision for a city that allows vehicles and pedestrians to flow smoothly to wherever they want to go.
