Managed Lane Network

A region-wide network of priced (“managed”) lanes on freeway systems.

Managed Lanes

"Managed lanes" are highway facilities or lanes whose operation is modified in response to changing traffic conditions.  Managed lanes operate as a "freeway-within-a-freeway" and is separated from the general-purpose lanes.  Examples include high-occupancy vehicle (HOV) lanes, value priced lanes, high-occupancy toll (HOT) lanes, or exclusive or special use lanes. Each of these concepts offers unique benefits; therefore, careful consideration is given to project goals and objectives in choosing an appropriate lane management strategy or combination of strategies. Project goals may include increasing transit use, providing choices to the traveler, or generating revenue.  http://ops.fhwa.dot.gov/publications/managelanes_primer/

Manual Lane

A toll lane wherein a Toll Service Attendant is present to accept cash, token or ticket as toll payment from a Customer.

Manual Vtoll

A scenario that takes place whereby the customer’s license plate information is used to establish vehicle identification in lieu of an Electronic Toll Collection (ETC) payment.  (If the license plate is not registered with an ETC account, the owner of the vehicle is assumed to be a toll evader or violator).

MBUF

Mileage-Based User Fee - A mileage based road user charge, also referred to as "vehicle miles of travel" (VMT) fees are prices for road use predicated on the mileage driven on a given class of roadway.

MEDIA Project

Management of Electronic Fee Collection (EFC) through Dedicated Name Short Type Range Communication (DSRC) Interoperability in the Alpine Area

MISTER

Minimum Interoperability Specifications for Tolling on European Roads. MISTER groups a team of experts on satellite navigation and cellular network-based electronic fee collection within the framework of a contract with the European Commission, DG TREN. The main objective is to prepare a complete draft of the ISO 17575 technical specification on the "Application Interface Definition for Electronic Fee Collection (EFC) based on Global Navigation Satellite Systems and Cellular Networks (GNSS/CN)". Its goal is to complement the ISO 17575 draft in order to set up a pan-European EFC service based on GNSS/CN.

Mixed Use Lane

A toll lane in which different kinds of means of payments are accepted (e.g. card-based and electronic toll transactions).

MLFF

Multi-Lane, Free Flow - The multi-lane free flow (MLFF) is a system that allows free-flow high-speed tolling for all highway users using electronic toll collection or video license plate recognition.

Mobility

The ability to move or be moved easily.

Modal Transfer

The transfer of traffic from one transport mode to another, normally from road to public transport.

Motorway

A road with at minimum of two lanes in each direction with specific parameters for width, ratio of turns, existence of emergency lane, and SOS columns. In Europe usually a Toll Road.

MoU

Memorandum of Understanding

MPO

Metropolitan Planning Organisations.

Multi-Protocol Technology

A multiprotocol technology bridges the interoperability gap between diverse RFID technologies used for electronic toll collection (ETC) and other ITS applications such as Automatic Equipment Identification and Electronic Vehicle Registration.
