He said other studies have shown that women cyclists tend to make huge detours to get to safer facilities, even if it takes longer, whereas men are more likely to take the most direct route, even if it is a busy street.
Better sidewalks for pedestrians and separate and protected lanes for cyclists would encourage active travel among what he calls risk-averse groups.
