Local transit -- Oregon -- Portland Metropolitan Area, Transit operators
This report analyzes factors contributing to short duration (one to three days) unscheduled absences among operators at TriMet, the transit provider for the Portland, Oregon metropolitan region. The analysis draws on a wide array of operator-specific information recovered by transit ITS technologies in combination with information from the agency’s human resources, scheduling, incident, and customer relations databases. The likelihood of an absence is estimated in relation to personal characteristics, employment status, aspects of assigned work, service delivery and performance indicators, temporal factors, and customer feedback. The findings can be used directly to support extraboard planning practices. More generally, the findings point to changes in policies and practices that would potentially reduce the incidence of short duration absences.
