$. Intersections of two arterials should be near right angles. 4. There should be no five or more legged intersections. Functional Systems The Federal Highway Administration, in cooperation with the State Highway Department, has completed a functional classification and needs study for all roads within the State. In 1969, a functional classification of existing systems was completed and, in 1971, a 1990 functionally cl,s- sified system was developed. These systems established a hierarchy of routes based on the relationship of mobility to land access, with the highest function serving mobility and the lowest function serving land access. This hierarchy is: 1. Class I - Principal Arterial (freeways) 2. Class II - Other Principal Arterial (expressways) $. Class III - Minor Arterial 4. Class IV - Collector 5. Class V - Local No attempt has been made at this time to relate these functional systems to jurisdictional systems at the national or state level. In developing a thoroughfare plan for Anoka County, certain assumptions regarding the relationships of function to jurisdiction were made. In general these Function Jurisdiction Principal Arterial I and II Minor Arterial Collector Local State County County & Municipalities Municipalities & Townships These assumptions, which are not completely valid for the existing systems, are importan% in identifying which systems should be the responsibility of the County and, therefore, should be the backbone of a County thorough- fare plan. Thoroughfare Standards ~e function of a road or street should relate to construction quality. This quality is generally described in terms of required dimensions and servicability. Dimensions and access controls describe a set of design standards.
