A June story on the website Inside Science presents several innovative intersection designs as a solution to the rising problem of traffic congestion.
These unconventional intersection designs - continuous flow, median u-turn, and diverging diamond - share a common feature. They focus on reconfiguring the flow-stifling left turn. See the linked article for accompanying video that illustrates some of these
Can these designs prevent the $2.3 billion gallons of fuel currently wasted each year by vehicles idling at intersections? We don't know if it's The Answer, but we're working hard to be part of the solution, not the problem.
For more details on innovative intersection design, including the diverging diamond interchange, mark your calendar for Feburary 3, 2010. OHM's Stephen Dearing, PE, Professional Traffic Operations Engineer will present More, Better, Faster: Existing and Innovative Interchange Designs. The webinar is co-sponsored by ASCE's Transportation & Development Institute and ASCE Continuing Education.
