Roadway Functional Classification System

Functional classification is the process by which the nation's network of streets and highways are categorized according to the type of service they provide. It represents the function of a roadway based on several factors including volume of traffic and types of trips served. 

Functional classification is used in transportation planning, roadway design and the allocation of federal roadway improvement funds. It was introduced by the Federal Highway Administration in the late 1960s, which developed federal guidelines for local governments and planning organizations to use in maintaining the functional classification system in their own jurisdictions.

Functional Classification Process

As the Metropolitan Planning Organization for the Kansas City region, it is MARC's responsibility to develop and maintain the functional classification system of roadways within its planning boundaries through coordination with local cities, counties and the state departments of transportation.

Proposing roadway classification changes

MARC accepts and reviews applications for proposed functional class changes from local governments and the state departments of transportation twice a year. Please refer to the schedule for deadlines.
