A statistic used to describe the typical (“average”) value for a group of values that is the middle value when the values are arrayed from highest to lowest value. See Mean and Mode.

Memorandum of Understanding

A document providing specific duties and responsibilities to be assumed by two or more parties in pursuit of a project or goal.

Metes & Bounds

A system that identifies a particular parcel of land by describing a series of metes (measurements) and bounds (directions) from defined reference points. The reference points may be such varied things as a tree or corner fencepost, but governments increasingly require a reference point to be more permanent. See Monument.

A location designated by the Chittenden County Regional Plan that is recommended to be a regional or sub-regional center for jobs, housing and community facilities that have an urbanized character.

Metropolitan Planning Organization

Federally established organization responsible for a cooperative, continuous, and comprehensive framework to make transportation investment decisions within their designated area.

Metropolitan Statistical Area

Defined by the U.S. Office of Management and Budget, an MSA is a county or a group of contiguous counties that contain at least one city of 50,000 inhabitants or more, or 2) An urbanized area of at least 50,000 inhabitants and a total MSA population of at least 100,000 (75,000 in New England). The contiguous counties are included in an MSA if, according to certain criteria, they are essentially metropolitan in character and are socially and economically integrated with the central city. In New England, MSAs consist of towns and cities rather than counties.

Metropolitan Transportation Plan

A federally-mandated long-range plan for transportation development and investment based on the goals in the CCMPO Vision Statement.

Metropolitan Transportation System

The multimodal network of highways, arterial and collector roadways, transit services, rail lines, Burlington International Airport, and other intermodal facilities critical to the movement of people and goods in Chittenden County.


A milemarker (i.e. milepost) is a reflective green paddle sign placed alongside highways indicating total mileage from an original control point. For Interstates, the zero milemarker originates at the southernmost, or the westernmost end of the route. However, for other routes, the location of the zero milemarker varies. The Vermont Agency of Transportation (VTrans) manages their milemarkers from South to North, and West to East. This is reflected in their distributed GIS data.

Minor Civil Division

A U.S. Census Bureau designated Minor Civil Division (MCD) is a legally specified (by State law) county governmental or administrative subdivision (e.g. township, gore, grant, unincorporated place, et al.). There states where MCDs do not exist. In such case the Census Bureau, in cooperation with state and local officials, delineates county subdivisions known as Census County Divisions (CCD). In some situations, the Census Bureau must complete the coverage of subcounty units by creating additional entities called unorganized territories (UTs) that it treats as being statistically equivalent to MCDs.

Minor Subdivision

A Subdivision that a community’s Subdivision Regulation permits to be reviewed using an expedited procedure and/or reduced plan requirements.

Mixed Income Housing

A housing project in which at least 15 percent of the total housing units are affordable housing units.

Mixed Use

Development of land, a building, or a structure with a variety of complementary and integrated land uses. 10 VSA 6001 (28): Construction of both mixed income housing and construction of space for any combination of retail, office, services, artisan, and recreational and community facilities, provided at least 40 percent of the gross floor area of the buildings involved is mixed income housing. Mixed Use does not include industrial use.

Mobile Source Pollutants

Vehicle-generated pollutants as regulated by the U.S. Environmental Protection Agency (EPA) for air quality. These include; Carbon Monoxide (CO), Hydrocarbons (HC) or Volatile Organic Compounds (VOCs), Nitrogen Oxides (NOx), Small Particulate Matter (PM-10), and Large Particulate Matter (PM 2.5).


A vehicle emission modelling software, which develops factors for predicting gram per mile emissions of Hydrocarbons (HC), Carbon Monoxide (CO), Nitrogen Oxides (NOx), Carbon Dioxide (CO2), Particulate Matter (PM), and toxics from mobile sources under various conditions. This model has been upgraded/replaced by a model called MOVES.


The door-to-door experience of traveling or shipping goods throughout our communities and across the region, measured in terms of travel time, comfort, convenience, safety, and cost.


A statistic used to describe the typical (average) value for a group of values that is the value that occurs most frequently in the group. See Mean, Median, and Multimodal.


One of several major types of transportation such as rail, bus, automobile, and non-motorized (bicycle/pedestrian) transportation.

Mode Split

The percentage, or share, of trips captured by the various transportation modes.
