Agency Wide Planning Studies:

• ALL ELECTRONIC TOLLING (AET) CONVERSION STUDY

  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.
