Denmark is one of the leading cycling nations, where cycling trips constitute a large share of the total trips and cycling safety assumes a top priority position in the agenda of policy makers. The current study investigates the risk factors associated with cyclist injury severity on Danish roads by examining a comprehensive set of accidents involving a cyclist and another party between 2007 and 2011. The current study estimates a generalized ordered logit model of cyclist injury severity because of its ability to accommodate the ordered-response nature of severity while relaxing the proportional odds assumption. Model estimates and average pseudo-elasticities illustrate that cyclist injury severity increases with (i) elderly cyclists over 60 years of age, (ii) cyclist intoxication, (iii) conflicts between cyclists going straight or turning left and other vehicles going straight, (iv) speed limits above 70-80 km/h, (v) slippery road surface, (vi) road sections, and (vii) heavy vehicle involvement. Moreover, model results show that cyclist injury severity decreases with (i) helmet use, (ii) the availability of cycling paths, and (iii) dense urban development.
