Analysis for a stop or yield controlled intersection results in solutions for the capacity of each lane on the minor approaches. The level of service criteria are then based on the reserve, or unused, capacity of the lane in question; expressed in passenger cars per hour (PCPH). Reserve Capacity Level of Expected Delay to (PCPH) Service Hinor Street Traffic -------------------------------------------------------------- >400 A Little or no delay 300-399 B Short traffic delays 200-299 C Average traffic delays 100-199 D Long traffic delays 0-99 E Very long traffic delays k g " When demand volume exceeds the capcity of the lane, extreme delays will be encountered with queuing which may cause severe congestion affecting other traffic movements in the Intersection. This condition usually warrants improvement to the intersection. Reference: Highway Capacity Hanual.

The modification entailed multiplying the through traffic by 1.2 and then dividing it In half. This allows for unequal distribution in the two travel lanes. With the existing control and geometrics, the operation at this intersection is at level of service D or better. This is considered to be acceptable. Acceptable operation is defined as level of service D or better. A description of level of service at unsignalized intersections is provided in Appendix C. Using Trip Generation, 5th Edition, ITE, Prospect Greens is expected to generate approximately 162 vehicle trip ends on a typical weekday at full build out. The daily and peak hour trip generation is shown in Table 2. The trip distribution used in the assignment process is shown below: West on Prospect - 60% East on Prospect - 40% Figure 3 shows the 1994 peak hour traffic plus the Prospect Greens generated traffic. Only the Prospect/Access intersection was evaluated in subsequent analyses. Using these traffic projections, the Prospect/Access intersection will operate at level of service C or better during both peak hours as shown in Table 3. Calculation forms are provided in Appendix D. The operation is considered to be acceptable. During the peak hours, Prospect Greens will increase the traffic on Prospect Road by less than 1%. The Prospect/Access intersection was analyzed using short and long range traffic forecasts on Prospect Road. Fort Collins Transportation Division staff was contacted to determine a growth rate for background traffic. Based upon the various forecasts used in the congestion management study, an annual growth rate of 1-2% was used for this segment of Prospect Road. Figures 4 and 5 show the respective short range and long range forecasts at the Prospect/Access intersection. The short range future year was 1997 and the long range future year was 2015. Tables 4 and 5 show the respective short range and long range peak hour operation at the Prospect/Access intersection. Calculation forms are shown in Appendices E and F, respectively. The key intersection will operate acceptably. It is concluded that the proposed Prospect Greens will not cause significant impact on the existing street facilities in the area. The Prospect/Access intersection will operate acceptably. 00 Cl) N O 00 �Z a 10 M 0 W M Q W x F- H To: From: Date: Subject: MEMORANDUM Larry Peterson, Peterson Brothers Homes & Development Ron Young, Remax Robert Van Uffelen, Parsons and Associates Bob Sutter, Architectural Horizons Tom Vosburg, Fort Collins Transportation Division Fort Collins Planning Department Matt Delich March 13, 1995 Traffic analysis for Prospect Greens (File: 94116ME1) This memorandum documents the analysis conducted with regard to the traffic operation at the Prospect/Access intersection to Prospect Greens in Fort Collins, Colorado. The site location is shown in Figure 1. The scope of this study was discussed with Transportation Division staff. Prospect Greens is a residential subdivision, consisting of 17 dwelling units (including an existing house).. From available plans, Prospect Greens would access the south side of Prospect Road via a private street between Ellis Street and Stover Street. This is an established neighborhood in Fort Collins. Prospect Greens is considered to be an infill development. Land use in the area is primarily residential. There are churches and schools in the area. Prospect Road is a four lane arterial street. Most local streets intersecting Prospect Road have stop sign control. The nearest signal is at Stover Street to the west. Prospect Road is posted at 30 mph. Peak hour turning movements were obtained in November 1994 at the Prospect/Ellis intersection. These counts are shown in Figure 2. Raw peak hour traffic data is provided in Appendix A. Table 1 shows the peak hour operation at the Prospect/Ellis intersection. Calculation forms are provided in Appendix B. Intersections along Prospect Road were analyzed using the unsignalized � analysis technique as published in the "Highway Capacity Manual," Special Report 209, TRB, 1985. Recent research indicates that the unsignalized analysis technique overstates the level of service at intersections on four lane major streets. This technique is being revised by TRB. Following review of the available research and conversations with the Chairman of the TRB Committee on Highway Capacity and Quality of Service, this technique was modified to take into consideration the
