Component

In September 1977 bicycle lanes were implemented on a 1.3 mi section of a one-way arterial pair in the central part of Madison, Wisconsin. On Johnson Street the bicycle lane was placed on the left side whereas on Gorham the lane was in the conventional location on the right side. Bicycle accident data and estimates of bicycle use in Madison for the 4 years before and after the introduction of the bicycle lanes were used to evaluate the safety impacts of the bicycle lanes. A statistically significant increase in bicycle accidents between the before and after periods was found, but the increase was traced to two specific types of accidents on Johnson Street that occurred primarily in the first year of the after period. In subsequent years the increase was not statistically significant in contrast to a significant increase in total bicycle accidents in the city. Recommendations for countermeasures to reduce the initial accident problems associated with the left-side bicycle lane are made.
