We then analysed added trips that would be- created from the Windy Hi l l and Cambridge Place developments.

Drivers trying to move- through the intersection will experience low speeds and long delays brought about by the congested conditions. The Erwin Road/Weaver Dairy Road- intersection will be affected minimally by- the new developments.. It. will maintain a service level A although volumes• will increase. This intersection's continued strong performance is due to its simple °three- legged° configuration. -'--Some decline- in service levels will .be seen at the_NC 86/Weaver Dairy Road intersection. The level of service- here is expected to- drop from A to C. This intersection would continue to provide acceptable service. Figures 7.1 , 7.2, and 7.3 show the critical movement analyses of the three intersections with ail approved developments occuppied. Windy Hill and Cambridge Place would add about 159 trips to the corridor. The additionai trips. wouid do little to worsen the level of service considering problems with this corridor created by previously approved developments, . Figures 8.1 , 8.2, and 8.3 show the critical movement analyses of the three major intersections that would be affected by the added developments. All three of the intersections would maintain virtually the same level of service with both Cambridge Place and Windy Hill occuppied. RECOMMENDATIONS We identified measures that could be taken to lessen the traffic impact of the approved and proposed developments. We feel that major •
