Better than speed bumps for slowing traffic.
Yes, there is a traffic circle (not a roundabout) in the intersection. They painted the lines to get people to slow down before they get there. But I don’t understand same striping layout after exiting the intersection.
Even at roundabouts, they design the curbs to get the driver to turn slightly left before entering to the right.
My guess is that this is a problem intersection, so the local agency is trying to figure out how to solve the issue, which is most likely speeding. Unfortunately, this striping job is too excessive. A major rule of traffic engineering is don’t make things too confusing for the driver. Too many decision points or confusing signage and striping can have a worse effect.
In my 30 years of experience, we would have tried the following based upon cost vs. benefit returns:
1) increase traffic enforcement by the police (this one rarely works as the cops hate traffic policing)
2) more and bigger speed limit signs along the route with blinking lights
3) Flashing Radar speed limit signs
4) rumble strips
5) speed humps or traffic circle
6) Roundabout or traffic signal systems
