  • Global Positioning System (GPS)/Automatic Vehicle Location (AVL) Use, Challenges, and Cost-Benefit in Operations
    Abstract: Automatic Vehicle Location (AVL) systems are helping DOTs achieve a variety of new efficiencies while improving or maintaining LOS through periods of state budget shortfalls. The trucking, emergency response, and transit communities have used GPS/AVL for years. Now DOTs are realizing new efficiencies with this technology as well. Recent findings on the challenges and cost-benefit advantages DOTs are finding with these technologies are discussed in this paper, summarizing the author’s 2011 and 2012 surveys of DOTs on this topic. For example, in addition to the 10% materials savings that DOTs in the US and Canada have reported, automated data collection associated with GPS/AVL is saving DOT maintenance forces thousands of hours filling out paperwork, boosting morale as well as effectiveness. WSDOT estimated the agency and the public benefit from an additional 10,000 hours per year that maintenance employees are out plowing instead of filling out paperwork, equating to a biennial savings of $700,000 in labor costs. The savings they found were such that WSDOT now aims to have all winter material application records, and material inventory issues recorded automatically, and the agency will begin to use their GPS/AVL equipment to help automate documentation of the maintenance staff performs on the state’s permanent stormwater control structures in the right-of-way, associating hours worked with GPS located stormwater facilities, to better understand life cycle costs, maintenance requirements, and document and communicate maintenance needs to the state legislature, for better funding.

    Submit a Discussion

    Attendees are welcome to submit a written discussion of any paper presented at the Annual Meeting. Written discussions will be considered for publication in the TRB Transportation Research Record series along with the paper being discussed. The author of the paper is given the opportunity to submit a written closure to the discussion. Please notify Rosa Allen at TRB by February 1, if you plan to submit a written discussion. When this notification is received, TRB staff will verify that the paper being discussed will be published and will provide the most recent version of the paper. This notification is therefore critical to ensure that all prepared discussions are used and to address issues in the most recent version of the paper in question.

    The discussion manuscript should be submitted to Rosa Allen by April 15 in electronic format as a Microsoft Word file (6.0 or later version). For the criteria used for discussions and for information on how to submit discussions for papers, see the Information for Authors document online at the TRB Annual Meeting website, under the Participant and Attendee Guides.
