Section 9B.04 - Bike Lane Signs and Plaques (R3-17, R3-17aP, R3-17bP)
Current through Register Vol. 28, No. 3, September 1, 2024
Standard:
01 The Bike Lane (R3-17) sign and the R3-17aP and R3-17bP plaques (see Figure 9B-2) shall be used only in conjunction with marked bicycle lanes as described in Section 9C.04.
Guidance:
02 If used, Bike Lane signs and plaques should be used in advance of the upstream end of the bicycle lane, at the downstream end of the bicycle lane, and at periodic intervals along the bicycle lane as determined by engineering judgment based on prevailing speed of bicycle and other traffic, block length, distances from adjacent intersections, and other considerations.
03 (DE Revision) Spacing of BIKE LANE (R3-17) signs is subject to engineering judgment and site specific constraints; however, as a general guide, in urban areas, and in rural areas with minimal access, spacing should be determined using the formula L = 2WS, where L is the spacing between signs, W is the width of the roadway, and S is the 85th-percentile speed.
