Here's an interesting, yet kind of frightening, story out of Rhode Island. Apparently nearly 700 stop signs recently popped up in the city of Cranston that hadn't been approved, or installed, by the City.
A month-long (that's right, it took an entire month to get to the bottom of this) investigation, installed at intersections with state roads, showed they were installed by the state Department of Transportation, following a state statute that requires drivers to stop before entering a state road.
This is part of why KMPO exists; to make sure all the area jurisdictions are communicating when it comes to transportation projects. Twice a month, we all sit down in a room and discuss what everyone's doing. Once a month its with the elected officials that make the decisions (KMPO Board meetings) and the other time its at our Kootenai County Area Transportation Team meeting, when the engineers and planners behind the projects discuss the technical aspects of what they're working on. Keep in mind that you're always welcome to attend.
