• Abstract:
  Inefficient use of drayage trucks results in negative externalities in the form of pollution and congestion. A clear ; awareness of the current state of drayage efficiency is especially important in Southern California since the cargo ; volume at the Ports of Los Angeles and Long Beach has just about recovered to its previous peak since the 2007- ; 2008 financial crisis. A full measure of this awareness can only be obtained through detailed tracking of drayage ; activities. GPS tracking has been used for fleet and asset management, and can certainly be adopted for tracking ; truck movements. Data obtained through GPS tracking, however, can provide detailed information of where and ; when a truck has been, but not what a truck is doing at a particular location. Such information would require ; driver inputs. Tablet computers provide an ideal platform for the design of an electronic on-board recorder that ; supports both GPS tracking and touch screen input. In this report we will present our experience with the ; development of such a device, and findings from the data collected through its deployment. ; A thorough understanding of drayage inefficiencies and their causes, and the freight flow pattern in a given area ; will not only provide useful data for the truck industry to devise strategies for productivity improvement, but also ; help stakeholders in supply chain management, including the ports and terminal operators, to identify the sources ; of inefficiency in drayage, quantify the impacts of these inefficiencies and develop solutions. Such understanding ; would be especially important in the Southern California area where the largest port complex in the United States ; is located and where a large and growing population resides.
