Level of Traffic Stress (LTS) is a road classification technique based on the comfort of bicyclists in the traffic stream. One commonly used LTS framework ranges from LTS 1 to LTS 4, classifying road segments that would be comfortable for any bicyclist to segments that only the fearless would brave on a bicycle, respectively. Over the past several years, a variety of papers have been written about different methods for assigning LTS values to road segments and how these LTS values have been used to inform planning and infrastructure decisions through connectivity analysis. Since demand modeling for bicycling is absent from many regional travel demand models (including DVRPC\u2019s), a measure of the potential use of a bicycle facility is difficult to obtain. Instead of focusing on demand, bicycle network connectivity is often used as an accessibility metric. Much of the connectivity analysis in prior research compared existing conditions to a \u201cbike-plan buildout\u201d scenario, or similar, to compare project merits. This project, instead, provides an example of a different type of LTS and network connectivity application.<\/SPAN><\/P>

Explore and view analyze results using the <\/SPAN>Bicycle Level of Traffic Stress (LTS) and Connectivity Analysis Tool <\/SPAN><\/A>- This regional screening tool was developed to help identify and rank roads where bicycle facility improvements would have the greatest local and regional connectivity benefit to the low-stress bicycle network. LTS is a road classification scheme based on the estimated comfort of bicyclists in the traffic stream. DVRPC\u2019s LTS assignment is based on the number of lanes, effective vehicle speed, and the presence and type of bicycle facility on the road segment.<\/SPAN><\/P>
