Layer: Bike LTS (ID: 56)

Name: Bike LTS

Display Field: Pri_Name

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: Centerline file used for Bike LTS Network. Has existing streets and bike paths integrated.Clean topology. All connections are end point to end point.Bridges involving bike paths cleaned manually to accommodate bug in Network Analyst connectivity using elevation fields.The Bicycle Level of Traffic Stress (LTS) system rates or scores streets and paths by calculating an LTS score (1, 2, 3, or 4) for each street or multi-use path segment, intersection approach, and intersection crossing and then assigning the highest of the three scores to the segment. In those cases where the intersection LTS score is higher than the street segment score, the street segment encompassing the first block on either side of the intersection is given the higher intersection score. LTS scores for street segments are based on the posted speed limit, traffic volumes, number of travel lanes, and bicycle lane or bicycle/parking lane dimensions. Multi-use paths are classified as the lowest stress (LTS score of 1). Please refer to the Low-Stress Bicycle Network Report, and updated segment methodology for additional detail. Description of Bicycle Routing OptionsThe routing application provides recommended bicycling route directions between an origin and destination using three different routing settings:Low-Stress Only: use of exclusively low-stress routes (LTS 1 or 2).Moderate-Stress: moderate-stress routes (LTS 1-3), but with low-stress preferred via a time penalty added to moderate stress routes when determining the route.Unrestricted: use of any legal bicycling route (LTS 1-4), but with low- and moderate-stress routes preferred via the most severe time penalty added to high-stress routes and a lesser penalty added to moderate-stress routes.Travel times shown are actual times (based on an average bicyclist’s speed of 10 mph) without the time penalties used by the application to determine the route.Description of LTS Levels for Street SegmentsLTS 1: Paths and streets with 1 lane per direction, speed limits ≤ 20 mph, and low traffic volumes, or up to 25 mph with bike lanes.LTS 2: Streets with 1 lane per direction, speed limits ≤ 30 mph, and low traffic volumes and/or bike lanes.LTS 3: Streets with 1-2 lanes per direction, speed limits ≤ 35 mph, and moderate traffic volumes and/or bike lanes.LTS 4: Streets with 2+ lanes per direction, with high speed limits and/or high traffic volumes.The LTS score for an intersection approach is based on the intersection configuration. Specifically, the score is based on whether there is a right-turn only lane and, if so, whether there is a “pocket” bike lane to the left of the right-turn lane and other details related to the design of these lanes and the curb radius of the intersection. Description of LTS levels for Intersection ApproachesNo effect: Simple intersection with no right-turn lane, or a single right turn lane of less than 75 feet with slow turning speeds.LTS 2: Intersection with a single right-turn lane of less than 150 feet and a bike lane that continues straight.LTS 3: Intersection with a right-turn lane of 75-150 feet and no bike lane, a bike lane that shifts to the left across a right-turn lane with slow turning speeds, or a bike lane that continues straight alongside a turn lane of more than 150 feet.LTS 4: Other intersection configurations, including multiple right-turn lanes and/or higher turning speeds.The LTS score for an unsignalized intersection crossing is based on the number of travel lanes per direction on the intersecting street to be crossed, the presence of a median (for multi-lane streets), and the speed limit on the intersecting street. Description of LTS Levels for Intersection CrossingsUnsignalized CrossingsLTS 1: Intersecting street has only 1 lane per travel direction and speed limit ≤ 30 mph.LTS 2: Intersecting street has only 1 lane per travel direction and speed limit ≤ 35 mph or 2 lanes but speed limit ≤ 30 mph.LTS 3: Intersecting street has 1 lane per travel direction and a speed limit of 40+ mph, or 2 lanes and a speed limit of 35 mph.LTS 4: Intersecting street has 2 lanes per travel direction and 40+ mph speed limit, or 3+ lanes.In some cases, intersection crossing LTS is reduced below these levels if the intersecting street is one-way only or is equipped with a median refuge. Signalized CrossingsCrossing streets at signalized intersections does not present a significant barrier for bicyclists and thus does not affect the LTS score unless a right turn lane is present.
