  • Abstract:
    In order to determine the feasibility of using cellular telephone location data in deriving the geographic extent

    (truckshed) from intermodal facilities, this study was conducted to determine the feasibility analysis in three aspects:

    technology, penetration analysis and truck tracking methodology. A preliminary test was also conducted to demonstrate

    the cell phone tracking and traveling characteristics identification process using Washington, D.C. metropolitan area data

    provided by AirSage, Inc.

    The preliminary feasibility analysis found that cell phone locations could be located within an average of 100 meters or

    less of their actual position, which is feasible to use for a long haul truckshed tracking from the intermodal facilities. Cell

    phone penetration analysis showed that only partial cell phone data were available for the truckshed tracking system. Thus,

    a long time period of observations are needed in order to increase the number of cell phones tracked.

    The research team developed a process and conducted a program for tracking cell phone trajectories and identifying the

    cell phone characteristics (truck or not). However, a database which covers possible truck traveling objectives, such as

    truck stops, rest area or warehouse, and land use categories, has to be established in order to identify the characteristics of

    the cell phones from the anonymous cell phone database.

    The preliminary test illustrates several examples for tracking cell phones and identifying the characteristics of cell

    phones based on the proposed tracking and identification process. The results show that the vendor provided data can

    provide enough cell phone data points for tracking the trajectory of cell phones. It also demonstrates that the developed

    tracking and filtering process and computer program are able to track every individual cell phone data point and identify

    the traveling characteristicss based on the trajectory and destination of cell phones.
