| Abstract |
| This study investigated the associations among work characteristics, safety practices, and accident experiences in delivery workers with and without assigned delivery times. Survey data were collected from 285 delivery workers in South Korea. Participants were divided into assigned-time (n = 146) and nonassigned-time groups (n = 139), based on whether the platform assigned them a specific delivery time. A multigroup path analysis was conducted using the same path model for both groups. Traffic signal violations were positively associated with accident experiences in both groups. In the assigned-time group, average daily travel distances and customer complaints were positively correlated with traffic signal violations. These violations, along with the number of daily deliveries and customer complaints, were also positively associated with experiencing accidents. Comparing individual paths revealed a potential between-group difference in the link from customer complaints to accidents. These findings highlight traffic signal violations as a key safety-related factor across delivery scheduling contexts and emphasize the importance of travel exposure, workload, and customer service demands in the assigned-time setting. Consequently, platforms and delivery companies should consider operating conditions and worker safety when determining delivery times, assigning workloads, and handling complaints. |
