Subject: Rumble Strips
Rusty and Jessica -
The Nashville Area MPO Staff would like to thank TDOT for reviewing rumble strip/stripe policy and practice related to the safety of bicyclists and all roadways users. The following is a list of items that may be helpful in your discussions:
A.) Statement from area bicyclists on affect of rumbles on bicycling (attached).
B.) Video and photos of Highway 109 and Highway 31, contrasting application of rumble on a shoulder less than 4'
(Highway 109) and application of rumble on a larger shoulder (Highway 31). (very useful)
C.) List of resources to consider when reviewing TDOT policy and practice
D.) Requests from Nashville Area MPO Staff regarding information and next steps.
Again, thank you for this opportunity. I will continue to work as a liaison between your department and the cycling community.
-Leslie

D.) MPO Requests:
- Can TDOT consider pausing installation of rumbles until a policy regarding how to accommodate the safety of bicyclists is adopted?
- Can TDOT provide an inventory of roadways which have already received rumble treatment and those that will receive treatment?
- Can TDOT do a typical section for how rumble stripes and strips will be handled on existing roadways?
- Can TDOT considering following the FHWA Technical Advisory on rumble strips and not install strips or stripes on roadways with less than 4' shoulder, regardless of whether or not the road a bike route in the TDOT long-range plan?
- Can TDOT consider doing the rumble treatments at high-accident locations instead of entire corridors?
- May we get clarification of when rumble stripes will be used instead of rumble strips?
- Can rumble stripes be put down in a minimum width and what is that width?
- Will breaks in rumble strips or stripes be considered regardless of whether or not the road is a bike route?
