Title:

Multimodal Investigation of Crashes Involving Aging Drivers, Passengers, Bicyclists, and Pedestrians

Accession Number:

Abstract:

Providing traffic safety to roadway users has been an important research topic for decades due to the considerable burden crashes put on both public and agencies. As such, factors that affect the crashes involving all roadway users (drivers, passengers, bicyclists, and pedestrians) have been investigated individually in the literature. However, to the authors’ knowledge, a simultaneous comparative investigation of crashes involving aging drivers, passengers, bicyclists, and pedestrians has not been done previously. In this paper, the authors explore common crash involvement patterns for these different aging groups while attempting to understand their individual characteristics, which impose crash involvement risk. To accomplish this, the authors adopt a Tobit model-based approach using Florida crash data supported by a spatial analysis namely density ratio difference approach (DRD). The proposed Tobit model is a special regression approach that incorporates two components: 1) a binary-data component which investigates whether a crash occurred on a roadway or not, and 2) a count-data component that evaluates the frequency of those crashes given that at least one crash has occurred. The results indicate some common patterns as well as distinct differences in crash involvement of different types of aging users of roadways. The findings of this research could enlighten agencies and decision makers towards creating more comprehensive safety plans focusing on not only aging drivers, but also aging passengers, pedestrians, and bicyclists.
