o Vehicle Travel Lane Widths Design Guidelines 1) Travel lane width is a function of the use of the lane, the type of vehicle served, and the speed of the vehicle. All of these factors, as well as whether the lane is an "inside" lane or an "outside" lane should be considered in deter- mining travel lane width. 2) lane widths should be wider on higher-speed streets than on lower-speed streets. .3) Outside lanes may require a wider width to accommodate turning trucks and buses, and to reduce the effects of adjacent obstructions like parked cars. If a bicycle lane is present, outside lanes need to be wide enough to provide for safety and comfort of bicyclists adjacent to those lanes. 4) Typical travel lane widths: a) Major Arterials. Travel lanes are typically 12' wide on major arterial streets. b) Minor Arterials. Travel lanes are typically 11'wide on minor arterial streets. ) c) Major Collectors. Travel lane widths are typically 111 wide on Major Collector streets, although wider lane widths may be required . for industrial areas or other areas with signifi- cant amounts of large truck traffic. d) Neighborhood Collec- tors. Typical travel lane widths on Neighborhood Collector streets range from 10' to 14'. The design width shall be determined by the use of the street: narrower lane widths are permitted on streets used only by motor vehicles; wider lane widths may be needed on streets which are used by a mix of motor vehicles, bicycles, and/or transit vehicles. Vehic;le Travel Lane Width Design Standards 1) The minimum travel lane width on Major and Minor Arterial streets is 111. 2) The minimum travel lane width on Major Collector and Neighborhood Collector streets is 101. ..WN ~L.. y;;:.... ~". ~'./"'~ 1':,,: .
