BUFFERED BIKE LANE<br />
Descrip on:<br />
Buffered bicycle lanes designate a por on of a roadway for exclusive use by bicycles (by way of striping, signage, and pavement markings)<br />
that is separated from the vehicular travel lane or from parked cars by a striped buffer space (typically 2-5 feet in width).<br />
Features:<br />
Ÿ Typical use on streets classified as residen al collectors and above<br />
Ÿ Includes a 2-5 foot wide striped buffer space to separate the designated bicycle lane from the vehicular travel lane or parked cars<br />
Benefits:<br />
Ÿ Allow for rela vely low cost/rapid implementa on without right-of-way acquisi on or major capital investment<br />
Ÿ Can replace underu lized travel lanes or parking lanes with simple re-striping<br />
Ÿ Provide higher level of safety and comfort for cyclists as compared to standard (unbuffered) bicycle lanes<br />
Ÿ If used adjacent to on-street parking, provide greater separa on between cyclists and parked vehicles, helping to eliminate "door zone"<br />
conflicts and crashes<br />
Ÿ Buffering helps dis nguish the lane as a dedicated space for cyclists, thus reducing the likelihood that it is mistaken for a travel lane or<br />
parking lane<br />
Ÿ Indicate clearly that bicycles have the right to be on the road and thus helps reduce poten al for bicycle/pedestrian conflicts on<br />
sidewalks<br />
Ÿ Encourage more predictable behavior by both motorists and bicyclists<br />
Ÿ Allow motorists and/or bicyclists to pass other bicyclists with less delay and with fewer passing conflicts<br />
Ÿ Improve sight distances at driveways and intersec ons<br />
Ÿ Increase the separa on between motor vehicles and sidewalks/pedestrians, thereby increasing the level of comfort for pedestrians and<br />
indirectly fostering pedestrian ac vity<br />
Ÿ May serve to calm traffic by crea ng the percep on of a more dis nct lane boundary<br />
Ÿ Provide addi onal turning space for trucks and transit<br />
Ÿ Provide shoulder space for disabled vehicles, mail delivery, bus stops, and cars yielding to passing emergency vehicles<br />
Challenges:<br />
Ÿ Require more space than conven onal (unbuffered) bicycle lanes<br />
Ÿ Addi onal markings and maintenance increase cost rela ve to conven onal (unbuffered) bicycle lanes<br />
Ÿ Motorists may park illegally in buffered lanes<br />
Ÿ O en collect debris and broken glass, which may render them (or sec ons of them) unusable; the buffer between the travel lane and<br />
bike lane may reduce the natural “sweeping” effect of passing motor vehicles, poten ally requiring more frequent maintenance (street<br />
sweeping)<br />
Ÿ May encourage poor behavior by bicyclists and right turning motorists at intersec ons and driveways, crea ng poten al conflicts (i.e.<br />
“right hooks”)<br />
Ÿ May create confusion among drivers as to whether they may cross buffer area to make turning movements<br />
