The higher levels of traffic stress 3 & 4 (LTS 3 and LTS 4) correspond to types of <br />cyclists characterized by the Four Types of Cyclists framework.' This categorization <br />of cyclist types is accepted throughout the bicycling planning practice across the U.S. <br />Level of traffic stress 3 (LTS 3) is the level assigned to roads that would be acceptable <br />to current "enthused and confident" cyclists and level of traffic stress 4 is assigned <br />to segments that are only acceptable to "strong and fearless" bicyclists, who will <br />tolerate riding on roadways with higher motorized traffic volumes and speeds. The <br />definitions for each level of traffic stress are shown below: <br />Table 2B-2: Bicycle Deficiency Analysis Scoring and Characteristics <br />Level of <br />Traffic <br />Stress <br />(LTS) <br />Description <br />Suitability <br />Traffic <br />Speed <br />Typical Locations <br />1 <br />2 <br />3 <br />4 <br />Little traffic stress <br />and requires less <br />attention <br />Little traffic stress <br />but requires more <br />attention and skill <br />Moderate stress <br />High stress <br />All cyclists (age <br />10 or higher) <br />Adult cyclists <br />with adequate <br />bike handling <br />skills <br />Most observant <br />adult cyclists <br />Experienced and <br />skilled cyclists <br />Low <br />Low <br />Moderate <br />Moderate <br />to high <br />Residential local <br />streets and separated <br />bike paths/cycle <br />tracks <br />Collector -level streets <br />with bike lanes or <br />a central business <br />district <br />Low -speed arterials <br />with wide bike lanes <br />or moderate speed <br />roadways with one <br />lane in each direction <br />High-speed or <br />wide roadways with <br />narrow or no bike <br />lanes <br />2B-15 I SYSTEM ANALYSIS <br />
