Or how do we improve traffic flow at this intersection? Or how do we this intersection safer?I disagree. Roundabouts are the answer to the question "Why do I have to stop at this stop sign/light when there is no one around?"
The former is what most of them in Valpo do. The first one they did at the LaPorte, Lincolnway, Sturdy intersections was a huge improvement. If anyone remembers the mix of stop lights and stop signs, it was horrible.
The latter is why they put one where IN2, 100S, and 300W come together. 5 way intersection with traffic on 2 hard to impossible to see from the other two roads.
