FCDOT conducts a site visit and develops a draft traffic calming plan.

The task force offers initial feedback on the draft plan.

Making the Plan

Traffic calming devices must fit on the roadway as it currently exists.

Vertical traffic calming devices must be at least 400 feet apart from each other and existing stop conditions.

Horizontal traffic calming devices must be 200 feet from other measures.

Traffic calming devices must have 150 feet for adequate sight distance.

Look for opportunities to combine measures for added effectiveness.
