At its June 2011 meeting the NCUTCD approved a recommendation to FHWA to remove this sentence in the next edition, and to add a new Standard statement that "If a pedestrian hybrid beacon is installed at or immediately adjacent to an intersection with a side road, vehicular traffic on the side road shall be controlled by STOP signs."<br /><br />This recommendation can be found at http://www.ncutcd.org/doc/201106/Attach%20No.%204%20Signals-Design%20of%20Pedestrian%20Hybrid%20Beacons%20Section%204F.02.doc<br /><br />Dwight Kingsbury Anonymoushttps://www.blogger.com/profile/04664749781126938809noreply@blogger.comtag:blogger.com,1999:blog-8962369200409301994.post-88616094947646739342013-07-13T12:23:00.849-07:002013-07-13T12:23:00.849-07:00Peter,

Bike signals are needed when <br />(A) Bikes cannot be served by the general vehicular signals. E.g., when there is a 2-way sidepath, there may not be a signal head on the same side of the street as the path for one of the path's directions. Or on a one-way sidepath adjacent to a right-turn lane controlled by its own green / red arrow.<br />(B) the time that the traffic signal program desires to give to bicycles is different from the time that is given to the concurrent vehicular movement. For example, for a leading bike interval, or for a bike phase that is protected from a right turn phase, or for a bike-and-ped-only phase.<br /><br />Peter Furth Unknownhttps://www.blogger.com/profile/10393591667224886268noreply@blogger.comtag:blogger.com,1999:blog-8962369200409301994.post-8196605280311471492013-07-10T22:26:21.224-07:002013-07-10T22:26:21.224-07:00I raised this issue.

In fact, the City doesn't use a wig wag (that's typically reserved for heavy rail crossings) and we leave the solid red operational until after the bike would have had a chance to clear the intersection. pkooncehttps://www.blogger.com/profile/13685359921487183869noreply@blogger.comtag:blogger.com,1999:blog-8962369200409301994.post-85385361143563301712013-07-02T07:34:13.928-07:002013-07-02T07:34:13.928-07:00Hi Peter

Some of the installations on multi use paths in the Phoenix area have had conflicts. Cyclists approaching on the path see the flashing don't walk, and think that because they're going faster than peds, they have time to clear. Drivers, seeing the wig wag and a clear crosswalk, are proceeding. Anonymousnoreply@blogger.com
