Don Diego project - traffic circle study

Fall 2004

The 2002 plan called for a complete rebuilding of the intersection, raising the level by 4" (standard traffic table and hump height). This is not so simple because of drainage problems: there are not drop-inlets (drains) at each of the corners to take care of rainwater.
We spent a Saturday morning with cones and chalklines at the intersection, observing the traffic behavior. We moved the cones around from time to time. Carrie directed traffic. There was a fair bit of confusion among left-turning drivers about how to deal with the circle. Many tried to pass in front, instead of going around.
The fire department came out with their biggest truck to see if they could negotiate the circle. They could not. Many cones were knocked over.
