Welcome to the MDTA's Projects and Studies page. Here you will find a list of our major Engineering and Construction Projects and Project Planning Studies.

Projects and services to operate, preserve, maintain, improve and protect MDTA's eight toll facilities are funded through the tolls customers pay to use the agency's facilities. The MDTA combines toll revenue from all facilities to pay operating costs and the debt on bonds that are issued to fund major projects.

    AET would provide toll collection at highway speeds through the electronic methods of E-ZPass and Video Tolling, just like on the ICC and I-95 ETL, at Maryland's seven toll plazas. The advantages of such a transition could include reduced travel time; increased safety/reduced crashes; alignment with national practice, which is shifting to AET; improved customer convenience; reduced emissions; and potential long-term reduction in toll collection and maintenance costs. The MDTA submitted a follow-up study report to the legislature on Jan. 1, 2016, as required by House Bill 389 passed during the 2014 legislative session.

    The MDTA addressed the following requirements of the legislation:

    • Analysis of AET in other states with description of various AET programs.
    • Analysis of AET interoperability.
    • Analysis of:
      • Alternative payment methods that do not exceed the existing cash rates.
      • Video Toll rates based on an analysis of actual costs and potential savings to collect Video Tolls.
      • Toll rates needed to address concerns with Video Toll collection of trucks.
    • Analysis of issues and factors related to AET that must be addressed before AET is implemented.
    • Overview of revisions, if any, to the MDTA's initial AET proposal.
    • Proposed legislation, if required, related to implementation of AET.
