The Federal Highway Administration (FHWA) recently updated and amended its Technical Advisories (TA) on the design and application of shoulder and edge line rumble strips (TA 5040.35 and 5040.39) to include issues of cyclists and cyclists’ safety.

Previously, the TAs contained little information on the needs of cyclists or the need for a public process when designing and installing rumble strips as part of road reconstruction or paving.  The revised TA (5040.39, Revised 1), released on November 16, 2011, includes a new section (Section 9) about the accommodation of all roadway users, with a special emphasis on the needs of cyclists and the measures that should be considered to accommodate them.
