SAFETY AND ECONOMICBENEFITS OF ROAD DIETSWITH BIKE LANESCynthia Hoyle, FAICPTransportation Planning Consultant
Safety Benefits of Bike Lanes Large body of research and evidence shows that properly designed and installed bike lanes reduce crashes1: When the city of Corvallis, OR installed 13 miles of bicycle lanes in one year, the number of bicycle crashes fell from 40 in the year prior to the installation to just 16 in the year afterwards…2 The addition of bicycle lanes in Davis, California reduced crashes by 31 percent.3 A comparison of crash rates of all types in major cities has shown that cities with higher bicycle use have lower traffic crash rates of all types than cities with lower bicycle use. 41.

Bike Lanes Improve Behavior1 Cambridge, MA - sidewalk bicycling cut in half after the installation of bicycle lanes on Mass. Ave. in Central Square.2 Wrong-way riding was significantly lower on the streets with bike lanes.3 On streets with bike lanes, 81% of cyclists obeyed stop signs, vs. 55% on streets without.4 Corvallis and Eugene, Oregon, cities with good bikeway networks, have the highest number of riders and rider behavior is the best: wrong-way riding is minimal, fewer ride on the sidewalk than in other Oregon cities.51.

Portland Bicycle Program Since 1996 Portland has doubled the miles of bike lanes Added thousands of bike parking spaces Had a 4-fold increase in bicycling Dramatic decrease in bicycle crashes and fatalities (79% of bicycle fatalities occurred outside of a bike lane.1)1. Portland Master Bicycle Plan – Existing Conditions Report, Chapter 6: BicycleSafety, pg. 6-19.
Portland Bicycle InfrastructureImproved Bicycle Safety“Portland’s decline in traffic fatalities is a public health triumph. Portland demonstrates that a transportation system emphasizing walking, bicycling and transit can achieve many public health goals - physical activity, clean air, and safety. Congratulations to the leaders and people of Portland.”Dr. Howard Frumkin, Centers for Disease Control (CDC)

Spending Analyzed by ModeWalkersandbicyclistsspent themostmoneyshoppingin thearea.
Study Conclusions The addition of bike lanes would be unlikely to harm local business and predicted that commercial activity on the street would likely increase. Three-quarters of merchants surveyed on the street believed that business activity would improve or stay the same if a bike lane replaced half of the on-street parking.
