Commercial Vehicle Delivery Activities in Seattle, WA

Data was collected over a total of 20 days, covering the period both before and after the locker installation at the Seattle Municipal Tower. Data collectors at the loading bay systematically tracked the number of trucks, total truck dwell time, truck parking location, the number and size distribution of parcels delivered, the number of packages picked up at the Tower, and the number of failed deliveries. After the locker was installed, data was collected to compare delivery time between floor-to-floor, door-to-door delivery and delivery to the locker. The research team developed a thorough data-collection process that included: • Developing two mobile applications in iPhone Operating System (IOS) as a data-collection tool • Recruiting and scheduling 11 data collectors to cover the 8 am to 4 pm shifts at the Seattle Municipal Tower during the pilot test • Training data collectors with both theoretical and in-field sessions • Managing data-collection tools (e.g. clipboards, iPads, safety vests) • Performing quality control on collected data (data cleaning)
