(d) "Access Review Committee" means a committee consisting of the Department right-of-way administrator, the state highway safety engineer, and the state traffic engineer. This committee shall decide access issues that deviate from these rules and regulations which are submitted to the committee by a district engineer.

(g) "Applicant means a landowner, easement user, grantee, or any other party that applies for or is granted an access.
(h) "Arterial" means a major highway or roadway designated to handle high volumes of traffic and/or high speeds. Mobility or the safe and efficient movement of people and goods is its primary purpose while access is a secondary or minor purpose.
(i) "Auxiliary lane" means a speed change lane allowing traffic to decelerate away from or accelerate to the speed of traffic in the main roadway travel lane(s). An auxiliary lane may also be used as a storage lane for right- and left-turning traffic. (See "acceleration lane," Section 2 [a], and "deceleration lane," Section 2 [n]).

(w) "Functional classification" means the hierarchy given to a roadway designating how that roadway is intended to operate. The main function of principal arterials is to move people and goods safely and efficiently; access to abutting property is a secondary function.
