This analysis overcomes the known limitations of police and emergency room bicycle accident databases through use of a survey that asked cyclists to indicate their accident history as well as their regular commute route to work or school. By relating the route information of the 1604 respondents (52.5% of the distributed questionnaires) to facility attributes in a Geographic Information System, defensible estimates of travel exposure on roads, off-road paths and sidewalks were developed.
