Thatll fix the problem
Regarding the article about the five Cary intersections set for upgrades: Its nothing that a few more roundabouts, concrete median barriers, one-way streets, red-light ticket cameras, informational signs, flashing purple and orange and white arrows pointing up, down and all around wont fix.
Plus, throw in new traffic lights at every intersection within a five-mile radius. Thatll fix these intersections. Dont worry about the costs.
