Analysis of injury severity of single-vehicle and two-vehicle crashes involving lightweight vehicles (K-car) in Japan: A random parameters approach with heterogeneity in means
Safety analysis for lightweight vehicles must be disaggregated by crash type while accounting for unobserved heterogeneity. The study reveals complex factors, such as the dichotomous risk profile of older drivers, which demand targeted policy interventions. These research findings provide an evidence-based framework for developing effective countermeasures, including enhanced driver assistance systems and improved roadway designs, to comprehensively improve the safety of lightweight vehicles.
