Ms. Hough,
Since the Shared Lane Markings (also known as "chevrons" and "bike under chevrons") will probably be applied this summer, I would like to bring to your attention design and placement guidance from the 2-January-2008 Federal Highway Administration publication of proposed new Manual of Uniform Traffic Control Devices (MUTCD).
Part 9, Section 9C.07 Shared Lane Marking provides options, guidance and standards for application and placement of the shared lane marking. Figure 9C-9 provides a detailed design of the shared lane marking. At the link: http://www.trafficsign.us/npa/part09compl.pdf , Part 9, Section 9C.07 can be found on pages 526 - 527 . Figure 9C-9 is on the last page.
The Bicycle Board's recommendations are congruent with the proposed MUTCD options, guidelines and standards but the MUTCD options, guidelines and standards may be more useful to you in your discussions with the WVDOH to obtain their concurrence with our plan to install the shared lane markings.
We look forward to news of your success!
Frank Gmeindl Chairman, Morgantown Municipal Bicycle Board
