Adding to Margaret’s post on speed tables are “speed humps.” A shorter version of speed tables and, as with tables, a less severe rise (and therefore less noisy) than speed bumps of the sort one sees on Winter St, Sandy Pond Rd, or in parking lots or private ways where the owner seeks to reduce speed.
“A speed hump is a raised section of asphalt approximately 10 to 14 feet long and 3 to 4 inches high. Speed humps are typically used on lower- speed residential streets in rural areas that are experiencing a high incidence of speeding and/or cut-through traffic. Speed humps are not to be confused with speed bumps, which are much shorter and usually found in parking lots. Speed humps have been found to reduce injury crashes by 40 to 50 percent and speeds by nine mph.” - Federal Highway Administration’s Speed Management- A Manual for Local Rural Road Owners https://safety.fhwa.dot.gov/local_rural/training/fhwasa010413spmgmt/speedmanagementguide.pdf The distinction is illustrated in this Federal Highway Administration summary of major speed reduction treatments. https://highways.dot.gov/sites/fhwa.dot.gov/files/2022-06/fhwasa16077.pdf On Tue, Sep 12, 2023 at 12:33 PM Margaret Olson <s...@margaretolson.com> wrote: > There are “speed bumps” and “speed tables”.
