Nor�che�1 G��-f SUdJEGT: Traffic Review - Label�e's �n both the Pianning Commission and Cpuncil me�iings concerning the l�aSelle's propasal for the northeast corner of Coun�y r�oad B and Fairvie�r, considerabZs discussion was given to the adequacy of the exis'ting roadways �n th�ir ability to carry existing and proposed traffic. Rrior to the tirst Planning Canmissi�n meeting the staff did review with the applicant's traf�ic engineer the da�a that he was presenting and at that time found zt to be consistent tirith good �raffic engineering prae�dur�. 7he f�gures used for determining traffic generatian from tne site were also reviewed at that �ir�e and found to be cons7stent witi� accepted standards. In the last w�e�C the staff has dane further investigation to both deternine the validi�y af the traffic caunts as they were proposed by �he applicants and deter- mine again the effect of the proposal upon the roadway system in the area. The t�affic caun'ts �ar Fairview and County Road �, as presented by ihe applicant, were taken frorn actual traffic coun�s taken in 1975 by Rarnsey Coun�y. In cornparing 3975 traffic caunts with co�nts ta�cen in 1973 and 1974, it was found that the volume of traffic an these roads i�as remained fair1y constant ov�r the past thre� years. Perhaps an indicatio� thai, for the most �art, this area substantially developed prior ta 1973. The effect o� tl�is proposal on the adjacent roadways was. investigated by using three methods, aI] of which point �o the conclusion that the existing raadway system is adequate to handle both the existing and proposed traffic tha� would develqp from this site. The three rr�thads and their rationale are listed below for your revi e��. � 7he first method was developed using Rar�sey CQUnty's standard traffic procedure. It is the3r policy thai each trave7ed lane can i�andl� 75Q vehicles per haur at the aeak hour. In using �his criteria it was found that on Fairvi�w Avenue, and on Caunty Road B, the assumed capacity �f each roadway would be 3,OQ0 vehic�es per hour. 7his is based on an uninterrupted tiaw of' traffic. The second method investigated was the one used by the app7icant's traffic eng�- r�eer. In this method it was found that the capacity of each of the roadways is 2,000 veh�cles per hour. This system does aliow for some conge5tion at in�er- sectians. It was felt by the staff�that a third method should be used as �t appear�d that tf�e four-way stop at the i ntersecti an of Cdun�y Road S and Fai rvi ew Aver� ue couZ d be ihe controiling point as �o capacity af th�s roadway. based on data obtained from the F{i ghway Capaci ty P�ianual , a standard source document, i t was found that the fniersection ha5 a ca�acity of 3,000 uehicles per haur. This compares ev�th the prapos�d traffic at the intersection of 2,400 venicles per hour.
