MUTCD regarding raised barriers

[Jim Baross]

FYI

Section 9E.17 Raised Devices (Class IV Bikeway (Cycle Track, Separated Bikeway or Separated Bicycle Lane)) 

Support: 

01  Chapter 3I contains information on using channelizing devices to emphasize pavement marking patterns associated with certain bicycle facilities. A common application is the use of flexible raised devices to create separated bicycle lanes (see Section 9E.07). 

02  Using inflexible raised devices immediately adjacent to the travel path of a bicyclist without a buffer creates a collision potential for bicyclists. 

Option: 

03  In accordance with Chapter 3I, channelizing devices may be used to emphasize a pavement marking pattern that establishes a bicycle lane or other bicycle facility provided that the installation of channelizing devices does not prevent motor vehicles from turning when the turn requires the motor vehicle to merge with the bicycle lane or facility as required by law or ordinance. 

Guidance: 

04  If used, channelizing devices for bicycle facilities should be tubular markers (see Section 3I.02).

 05  The selection of a raised device for use with bicycle facilities should consider the collision potential of both the post and the base since the base might still be present in the event the post is struck and missing. 

Support: 

06  Measures to reduce the likelihood of a road user striking a channelizing device include marking a buffer space, improving lighting, improving retroreflectivity, or the periodic addition of taller vertical elements within runs of shorter elements.
