| Mr. Dearing stated that roundabouts were a form of a circular intersection, |
|
| which had been around since the dawn of time. They came in all shapes |
|
| and sizes; they formed pre-eminent focal points for some communities, |
|
| such as Paris, or they could be tiny and fit into neighborhoods. There |
|
| were some problems with larger circular intersections because vehicles |
|
| weaved in like they did on freeways, and in reality that did not work. By |
|
| the mid-1950’s, circular intersections fell out of favor all over the world, |
|
| and companies made a lot of money tearing them out. A lot were |
|
| converted to traditional signalized intersections. In the old way, people |
|
| using roundabouts would yield to the vehicle on the right, meaning that |
|
| anyone already in the roundabout had to yield to entering traffic. If people |
|
| were always letting traffic in and not accommodating the people that were |
|
| already in and letting them out, traffic got locked up. Folks in England |
|
| wondered why they did not work, so they put a lot of money into it and |
|
| figured it out. They had to change the rules of the road - they could not |
|
| always let traffic in and not accommodate the traffic already circulating. |
|
| Instead, entering vehicles had to yield to those circulating, and that |
|
| unlocked a lot of the problems with the old traffic circles. He showed a |
|
| picture of a traditional roundabout, which had a central island and splitter |
|
| islands on all approaches to help channelize the traffic. Vehicles were |
|
| told where they had to yield, and the pedestrians were accommodated. |
|
| Pedestrians were away from the entry point, and they would typically be |
|
| one or two cars back from the yield line. He indicated that the modern |
|
| roundabout worked very well. |
