Research suggested that motorists right-of-way (ROW) violation in automobile motorcycle gap-acceptance accidents at priority (i.e., stop-/yield-controlled) T-intersections has been a safety concern to motorcyclists. Thisstudy examines the characteristics of automobile motorcycle gap-acceptance accidents that occurred at such locations. British Stats19 accident injury database during 1991-2005 are examined in detail. Automobilemotorcyclegap-acceptance accidents are classified into three crash scenarios: approach-turn, angle crossing, and angle merging crashes. Mixed (random parameters) logit models are estimated to investigate the contributory factors tomotorists ROW violation in these three crash types. Crash features are also compared among gap-acceptance accidents and other crash scenarios. Themethodological approach adopted allows for the individuals within the observations to have different parameter estimates as opposed to a single parameter representing all observations (i.e., accounts for unobserved heterogeneity potentially relating to roadway/environmental characteristics, andmotorist behaviours). It was found that motorcycles ROW was more likely to be violated on non-built-up roads, and in diminished light conditions, with non-uniform effects across the observations. Elderly/female motoristsappeared to be over-represented in gap-acceptance crashes. Implications of the findings are discussed. (A) Reprinted with permission from Elsevier.
