FDOT Statewide Lane Elimination Guidance

This FDOT Lane Elimination Guidance is a resource for advocates across the state to reference.

Road diets work. West Palm Beach owes much of its downtown revitalization to successful road diets on Clematis Street and Dixie through downtown, and a successful rightsizing of Olive Avenue that stitched back together the campus of Palm Beach Atlantic University and the neighborhoods to its south. (Great video presentation on the history of these projects by Ian Lockwood, City Transportation Engineer at the time).

The FDOT process outlined in this document has been used successfully. Tequesta, a city to the north of West Palm Beach, recently gained approval for a six-to-four lane elimination using this process. Road diets are a proven safety tool to reduce frequency and severity of collisions and make streets more livable, endorsed by the Federal Highway Administration.

This guidance is quite good, and contains an appendix of lane elimination projects in Florida (Appendix A). Appendix C contains existing lane elimination request processes for various FDOT districts.

    page 46 of the guide:
    “Generally a five or six-foot wide bicycle lane next to an eight-foot wide parking lane does not have dooring issues”

    I think a lot of bike advocates will disagree with that one. I thought a five foot bike lane next to you parallel parked car is by definition a door zone bike lane.

    They should provide a reference for that statement.

    It contains a reference from Donald Shoup’s The High Cost of Free Parking. Amazing to see that in DOT publication.

    page 46:
    If free on-street parking is provided, it will reduce the market price of parking of all types (including off-street parking). Because providing this parking has an associated cost, it is in essence a subsidy that incentivizes automobile travel and inflates parking demand. [14]
