Roundabout Corridor

B&N recently completed construction plans for a new interchange and related improvements in the rapidly growing Dublin area. Central to the effort was completion and approval of the Interchange Modification Study (IMS) for the interchange and surrounding areas. The IMS originally approved for the project included a partial cloverleaf interchange with traffic signals at the ramp terminals. The City of Dublin, a progressive advocate of roundabouts, then requested that B&N perform an evaluation using roundabouts instead of traffic signals at the interchange. The amended IMS showed that roundabouts would reduce delays, increase safety, and decrease vehicle emissions over the signalized alternative. Four roundabouts were involved including at the ramp terminal intersections.

*3D Models visuals and animations were developed using a the strengths of several state-of-the-art modeling tools including VISSIM, 3DS Max and Sketch-Up.

@oyo4jc On the other hand, it is the best, most efficient way of intersecction. It can only go wrong if indications prior to entry are not well placed. As long as you know where you are going, and you know how to read, youll be safe, and traficc congestion minimized. Good luck. Fear to the unknown is common.

Roundabouts are safer than the cheap stuff we use here in the States. Traffic lights are easy to implement and cheap. Rounabouts require thinking that thus save lives... and Americans don't have the mindpower to do that. Roundabouts cause cars to go slower since they are going around a bend. If there's an accident, roundabouts make it so the collision is at an angle meaning less damage and a collision in one place on a traffic circle allows cars to move freely elsewhere during a accident.

@oyo4jc My mum was almost killed at a four-way traffic-light intersection as she was hit by a speeding truck at a perpindicular angle denting the car at half its width, the car spun 4 times and stopped all traffic. If it were a roundabout, the truck would have been traveling slower, she would have been hit at an angle (meaning fewer injuries) and traffic would still be able to move at other places along the traffic circle. The only reason you don't want it is because you know nothing about it.

The best way to make people HATE driving. I pray that people get a clue and protest these horrid things here in the USA.

@killwize No, in Upstate New York, this would be disastrous :)

Hmm, a dumbell interchange. One of my favourites!!!

[randyseck]

Maybe its more efficient, by way confuse the hell out of people......
