Vehicle Travel Lane Widths <br />Design Guidelines <br />1) Travel lane width is a function of the use of <br />the lane, the type of vehicle served, and the <br />speed of the vehicle. All of these factors, as well <br />as whether the lane is an "inside" lane or an <br />"outside" lane should be considered in deter- <br />mining travel lane width. <br />2) Lane widths should be wider on higher-speed <br />streets than on lower-speed streets. <br />3) Outside lanes may require a wider width to <br />accommodate turning trucks and buses, and to <br />reduce the effects of adjacent obstructions like <br />parked cars. If a bicycle lane is present, outside <br />lanes need to be wide enough to provide for <br />safety and comfort of bicyclists adjacent to those <br />lanes. <br />4) Typical travel lane widths: <br />a) Major Arterials. Travel lanes are typically <br />12' wide on major arterial streets. <br />b) Minor Arterials. Travel lanes are typically <br />11' wide on minor arterial streets. <br />c) Major Collectors. Travel lane widths are <br />typically 11' wide on Major Collector streets, <br />although wider lane widths may be required <br />for industrial areas or other areas with signifi- <br />cant amounts of large truck <br />traffic. . <br />d) Neighborhood Collec- <br />tors. Typical travel lane <br />widths on Neighborhood <br />Collector streets range from <br />10' to 14'. The design <br />width shall be determined <br />by the use of the street: <br />narrower lane widths are <br />permitted on streets used only by motor <br />vehicles; wider lane widths may be needed. <br />on streets which are used. by a mix of motor <br />vehicles, bicycles, and/or transit vehicles. <br />Vehicle Travel Lane Width <br />Design Standards <br />1) The minimum travel lane width on Major and <br />Minor Arterial streets is 11'. <br />2) The minimum travel lane width on Major Collector <br />and Neighborhood Col lector streets is 10'. <br />7 <br />
