Need some sort of flashing lights on the stop signs at Ada and Chicago Ave. Such lights on the stop signs are being used in many other neighborhoods ... some have just one flashing light on the top of the stop sign and some even have lights all the way around the stop sign. I live and work by this intersection and can see and hear cars slamming on their brakes on a daily basis because the drivers don't notice the stop signs. I've also seen a few close calls with pedestrians as this crossing is located between a school and the park. I'd hate to see someone get hurt before something gets done about it.
