The national study by @Boenau (2026-06-09) assesses narrowing vehicle lanes as the easiest and most cost-effective method to add sidewalks and protected bike lanes within current roadway footprints. It compares potential lane‑width reductions across road classifications and centers on quantifying safe limits—asking to what extent narrowing can occur without increasing traffic safety risks.
National study posted by @Boenau on 2026-06-09 evaluates narrowing vehicle lanes as the simplest, most cost-effective way to create space for sidewalks and bike lanes within existing roadways.
This national study investigates the feasibility of narrowing vehicle lanes as the easiest and most cost-effective way to accommodate better sidewalk and bike lane facilities within the existing roadway infrastructure. The study asks whether, and to what extent, we can narrow existing vehicle lanes (for different road classifications) without adversely impacting traffic safety.
