Description: Innovative, Alternative Intersections are often able to reduce traffic congestion in affordable, sustainable ways. Many designs, while serving more vehicles, have traffic calming, are bike and pedestrian friendly, and create a platform for Place-Making catalytic change. Mixed-use, Transit-Oriented Developments will benefit from these unconventional, Innovative, Alternative Intersection designs.
