Factors Influencing Pedestrian Crashes in Dhaka City: A Multiple Correspondence Analysis Approach
Pedestrian road safety is a major concern in Dhaka, where pedestrians account for 65% of fatal crashes. To alleviate this situation, pedestrian safety aspects must be identified. Using a multiple correspondence analysis (MCA) approach, this study examines 631 pedestrian accidents in the Dhaka metropolitan area from 2017 to 2020. In this study, twenty categorical variables were used, including pedestrian age, location and action at the time of the accident, driver intoxication, road geometry, and lighting condition. In the first two dimensions, pedestrian location and action at the time of the crash, injury severity, lighting condition, and time of crash are found to be the most discriminant. The eight distinct clusters were later identified in this study. By analyzing these clusters, research showed that while crossing the street, pedestrians aged forty to sixty are associated in fatal crashes. Pedestrian crashes are also more common at night when visibility is low. Male pedestrians are more likely to be involved in accidents on uncontrolled roadways, while female pedestrians are more vulnerable at cross and tee junctions. Elderly drivers are more likely to collide with a pedestrian while making a right turn in an unusual road geometry. Furthermore, it has been discovered that overtaking behavior in car drivers results in severe pedestrian accidents. Some key countermeasures suggested in this study to assuage pedestrian safety include the installation of street lights for nighttime visibility, ramps for senior pedestrians, guardrail, retro reflective marking for elderly drivers, adequate sight distance at intersections, speed calming devices, and so on. Finally, it is expected that the outcomes of this study will assist the policymakers to understand the factors that contribute to pedestrian crash severity and fatality, as well as aid in the implementation of necessary measures to reduce unexpected and avoidable road losses.
