a <br />GEOMETRICS <br />The design guidelines in this section are for independent paths <br />and were developed from the recommendations of several sources <br />including, the American Association of State Highway and Trans- <br />portation Officials (AASHTO) , Department of Transportation <br />Federal Highway Administration, "Bikeways - State of the Art - <br />1974," and Bikeplan Hawaii. In the case of bike lanes and routes., <br />which are located on existing streets, roadway geometries should <br />be checked for compatibility with bikeway standards, <br />Bikeway_ Surface Widths <br />Using bicycle space requirements (Figure 5 ) minimum and <br />desirable bikeway surface widths have been developed: <br />Minimum Desirable <br />Number of Lanes Width Width <br />1 3.5 feet 5.0 f eet <br />2 7.0 feet 10.0 feet <br />3 10.5 f eet 15.0 f eet <br />4 14.0 feet 20.0 feet <br />The bikeway surface width for a bike /walk path is provided <br />in Figure 7. <br />In order to provide suf fic'lent bikeway width for saf a and <br />comfortable maneuvering, the following adjustments to <br />bikeway widths are to be used (Figure S, page 15) . <br />Additional Width (feet) <br />Condition Minimum Desirable <br />Raised curb on one side 95 100 <br />Raised curb on two sides 100 2,90 <br />Parked cars adjacent 2, 0 3.0 <br />-12- <br />
