Thanks to the many bicyclists who reponded to the BCO's request for Cyclist Input, the new AHTD Rumble Strip Policy includes bicyclist-oriented compromises.
The goal of the new rumble strip push is to minimize the number of traffic fatalities that result from a driver inadvertently leaving the roadway. The noise of the tires hitting grooves in the pavement often alerts a distracted or drowsy driver. The design and placement of these grooves drastically affects the accessibility of a road for cyclists.
- Installation of shoulder rumble strips on all rural, divided highways with partial access control was changed from a requirement to a recommendation (shall was replaced with should).
- Shoulder width guidance was added to accommodate bicyclists and provide some flexibility in accordance with the FHWA TA 5040.39.
