township in which they are located. The following characteristics of each routes segment are given: 1) route function; 2) approximate length in miles; 3) the estimated 1990 traffic volume classification; and, 4) the route planning number. The estimated 1990 traffic volume clas- sifications are as follows: A. Over 12,000 vehicles per day B. 4,000 - 12,000 vehicles per day C. 1,000 - 4,000 vehicles per day D. Under 1,000 vehicles per day A four-lane road facility is recommended for volume classifications A and B. Obviously, the entire plan cannot be implemented at one time. Rather it is intended to be implemented incrementally as specific elements are built. It is extremely important to follow through on the imple- mentation of all system levels when a new plan element is completed. If, for instance, a new minor arterial is developed in conformance with the plan, it is also essential to develop divertors and to utilize other traffic engineering measures to force the collector and/or local function of the facility which the new arterial replaces. Figures 1S and 16 illustrate this concept. The disposition of all County roads has been made in the Thoroughfare Plan. Table 4 gives a summary of the functional classification of existing and recommended County roads. It is recommended that 7.8 miles of the existing County road system attain the function of principal arterial and come under the jurisdiction of the State. 205.7 miles of the present County system and an additional 43.1 miles of new location routes should function as minor arterial routes. These routes should come under the jurisdiction of the County and should comprise the CSAH system..]69.7 miles of the existing County road system and an additional ll.0miles of new location routes should function as collector routes and should be under the jurisdictions of the County and municipalities. 21.5 miles of the present County road system should function as local roads and should be under the juris- diction of the municipalities and townships. Recommended Access Control Policies Hxperience indicates that controlled access arterials are economical in the long run. The arterial without access control begins to lose capa- city as soon as roadside interference begins, whereas the controlled access arterial consistently retains its ability to carry traffic. The non-controlled access arterial soon becomes obsolete, and the result is the costly necessity of relocating and constructing a new arterial. I I I I I 64
