Level of Traffic Stress


Researchers at the Mineta Transportation Institute in San José, California developed the Level of Traffic Stress method to evaluate level of service for bicycle travel. Currently, most U.S. cities have “islands” of low-stress connectivity for bicycles, but these islands are separated by freeways, high-speed arterials and other barriers that make bicycling unattractive to most people. Based on Dutch standards for bicycle facility design, the method classifies bicycle facilities from 1-4, with highest ratings given to physically-separated facilities and facilities with low exposure to auto traffic and easy crossings at intersections.
