Comments on: The “Speed Lump.” Not a Typo. It’s Inexpensive Traffic Calming. http://www.streetsblog.org/2007/02/22/the-speed-lump-not-a-typo-its-inexpensive-traffic-calming/ Covering the New York City Streets Renaissance Fri, 10 Feb 2012 16:07:00 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Matthew Ridgway http://www.streetsblog.org/2007/02/22/the-speed-lump-not-a-typo-its-inexpensive-traffic-calming/comment-page-1/#comment-30305 Matthew Ridgway Wed, 28 Mar 2007 21:04:44 +0000 http://www.streetsblog.org/2007/02/22/the-speed-lump-not-a-typo-its-inexpensive-traffic-calming/#comment-30305 Clarence - Humps were developed to address concerns related to emergency response times. They are designed such that a large truck can traverse the hump with little vertical displacement. Unfortunately, this also means that large SUVs derive the same benefit so humps are sliughtly less effective than humps. That bit of information is hopefully payment for gaining access to the video you prepared on physically separated bike lanes. I am a member of the Institute of Transportation Engineers (ITE) Pedestrian and Bicycle Council and we are interested in starting a research project on appropriate applications of these facilities. You likely know that they are expressly discouraged in most roadway design manuals. Please contact me and we can talk more.

They warp and wear out. Also, the paint on the speed lumps fades and they become hard to see at night. They can't be r-used if pulled up for snow plows each winter. Only one company has mini-hump that solves all those problems. Make speed lumps out of recycled material sounds great but doesn’t work. They warp and wear out.

Another important thing about the placement of these: Alameda has a bike route that circles the island. Bayview Drive is part of that network.

But the easy installation / removal and bike friendliness likely outweigh that.
