Nisich, City Engineer FROM: iloi Bahman Janka, City Traffic Engineer DATE: June 29, 1994 SUBJECT: WHITES CANYON, VIA PRINCESSA, AND RAINBOW GLEN DRIVE - TRAFFIC STUDY BACKGROUND Due to the recent completion of the Whites Canyon bridge, new roadways have been open to the public: Whites Canyon Road, Via Princessa and Rainbow Glen Drive. There is a need for additional traffic control for the new roadways and the Traffic Engineering section conducted Engineering and Traffic Surveys and on -street parking evaluations on the subject roadways and one-way and four-way stop control evaluations at the intersections along Via Princessa and Rainbow Glen Drive. RECOMMENDATIONS Based on the results of these studies, the following are recommended: 1. Prima facie speed limits (illustrated in Exhibit "A"): a. Whites Canyon Road from Soledad Canyon Road to Via Princessa 50 mph b. Via Princessa from Rainbow Glen Drive to Whites Canyon Road 45 mph c, Via Princessa from Whites Canyon Road to Sierra Highway 50 mph d. Via Princessa from Sierra Highway to East City Limits 45 mph e. Rainbow Glen Drive from Gilbert Drive to Via Princessa 35 mph 2. On -street parking prohibition/no-stopping zone (illustrated in Exhibit "B"): a. Whites Canyon Road between Soledad Canyon Road and Via Princessa. b. Via Princessa between Rainbow Glen Drive and Sierra Highway. c. Rainbow Glen Drive between Gilbert Drive and Via Princessa (total of 3,900 feet on both sides of street). 3. Installation of a four-way stop control at the intersection of Rainbow Glen Drive and Via Princessa (see Exhibit "B"). Antony J. Nisich, City Engineer June 29, 1994 Page 2 4. Installation of one-way stop control at the intersections of Fanchon Lane/Rainbow Glen Drive, Flo Lane/Rainbow Glen Drive, Gregory Lane/Via Princessa, and May Way/Via Princessa (see Exhibit 'B".) WHITES CANYON ROAD BETWEEN SOLEDAD CANYON ROAD AND VIA PRINCESSA - This segment is a north/south major roadway with three travel lanes in each direction with a raised median island in the center. The roadway is 84 feet wide with curb/gutter and sidewalk on each side. No traffic accident record is available for this roadway segment. No speed limit signs are posted at the present time. VIA PRINCESSA BETWEEN RAINBOW GLEN DRIVE AND SIERRA HIGHWAY - This segment is presently an east/west secondary roadway with two travel lanes in each direction. The roadway width varies from 64 feet to 84 feet with curb/gutter on each side. A sidewalk has been constructed between Rainbow Glen Drive and Whites Canyon Road. A two-way left turn lane exists between Rainbow Glen Drive and Whites Canyon Road, and raised and painted medians exist between Whites Canyon Road and Sierra Highway. There has been one reported traffic accident along this portion of the roadway which has recently been opened to traffic. No speed limit signs are posted at this time. A Metro -link station exists on the north side of the roadway at the signalized intersection of Weyerhaeuser Way. VIA PRINCESSA BETWEEN SIERRA HIGHWAY AND EAST CITY LIMITS - This segment is an east/west major highway with three travel lanes in each direction and a raised median island in the center. Curb/gutter and sidewalk exists on each side of the roadway. No speed limit signs are posted at the present time. A major commercial site (Price Club) exists on the north side of Via Princessa east of Sierra Highway. Records show that three intersection accidents were reported in 1993 at the intersection of Sierra Highway and Via Princessa. RAINBOW GLEN DRIVE BETWEEN GILBERT DRIVE AND VIA PRINCESSA - This segment is a north/south collector street which has one travel lane in each direction. The roadway is 40 feet wide with curb/gutter and sidewalk on each side. This segment of the street intersects with several public and private streets. Horizontal and vertical curves exist on this street. This segment of the street has recently opened to through traffic, and there has been only one traffic accident in this section since January, 1993. No speed limit signs are posted along this roadway. Rainbow Glen Drive, north of Gilbert Drive has an established and posted speed limit of 35 mph. VIA PRINCESSA/RAINBOW GLEN DRIVE - These two streets form a four-way intersection. Each approach is controlled by a stop sign. Antony J. Nisich, City Engineer June 29, 1994 Page 3 DATA Speed samples collected on the subject roadway are illustrated in the table below: Street Whites Canyon Road Soledad Canyon Road to Via Princessa Via Princessa Rainbow Glen Drive to May Way May Way to Whites Canyon Road Whites Canyon Rd to Weyerhaeuser Way Weyerhaeuser Way to Sierra Highway Sierra Highway to Price Club Entrance Price Club Entrance to East City Limit Rainbow Glen Drive Gilbert Drive to Via Princessa 85th Percentile Speed 50 mph 10 Mile Pace M 41-50 mph (69) 46 mph 38-47 mph (72) 46 mph 36-45 mph (71) 52 mph 42-51 mph (69) 54 mph 42-51 mph (75) 46 mph 37-46 mph (74) 48 mph 38-47 mph (71) 42 mph 33-42 mph (72) 24-hour traffic volumes were collected at the intersection of Rainbow Glen Drive and Via Princessa and utilized in the multi -way stop analysis. SPEED LIMIT. The speed limit normally should be established at the 85th percentile speed (defined as the speed at, or below, which 85 percent of the traffic is moving) or the nearest five miles per hour below it. However, in matching with existing conditions and with traffic safety needs of the community, engineering judgement may indicate the need for a further reduction. Whites Canyon Road between Soledad Canyon Road and Via Princessa - Based on the 85th percentile speed, post the speed limit at 50 mph. Via Princessa between Rainbow Glen Drive and Whites Canyon Road -Based on the 85th percentile speed, post the speed limit at 45 mph. Via .Princessa between Whites Canyon Road and Sierra Highway - Based on the 85th percentile speed, post the speed limit at 50 mph. Via Princessa between Sierra Highway and East City Limit - Based on the 85th percentile speed, post the speed limit at 45 mph. Antony J. Nisich, City Engineer June 29, 1994 Page 4 Rainbow Glen Drive between Gilbert Drive and Via Princessa - Based on the horizontal and vertical curves, intersecting public and private streets and consistency with the northerly section, reduce 85th percentile speed, and post the speed limit at 35 mph. ON -STREET PARKING PROHIBITIONS: Whites Canyon Road between Soledad Canyon Road and Via Princessa between Rainbow Glen Drive and Sierra Highway were designated as major and secondary highways. The elimination of on -street parking from major and secondary highways is intended to reduce potential conflict between through traffic and parked vehicles, increase traffic capacity of each street, and enhance the aesthetics of the street system. Rainbow Glen Drive between Gilbert Drive and Via Princessa, a total of 3,900 feet of no -stopping zones are needed to ensure the sight visibility at intersecting streets and reduce potential conflict between through traffic and parked vehicles. Staff has met and discussed with the representatives of the homeowners along Rainbow Glen Drive regarding the establishment of "no -stopping" zones on Rainbow Glen Drive. The representatives agreed with the establishment of "no -stopping" zones along Rainbow Glen Drive. No -stopping signs have already been placed on the above streets to effect the no -stopping regulations. FOUR-WAYSTOP: According to the Caltrans' standards, four-way stop signs are ordinarily used where the volumes of traffic on the intersecting streets are approximately equal. They are also installed where a safety problem is demonstrated by an occurrence of five or more accidents in a 12 -month period which are susceptible to correction by the installation of a multi -way stop control. Since the intersection of Via Princessa and Rainbow Glen Drive is new, only the traffic volume and speed limits were applied in analysis. Based on the collected traffic volume and vehicle speeds, a four-way stop control installation is warranted at the intersection. ONE-WAY STOP: A one-way stop control is recommended at the following locations to provide a positive right-of-way control and enhance traffic safety at the intersections: • On eastbound Fanchon Lane at Rainbow Glen Drive. • On eastbound Flo Lane at Rainbow Glen Drive. • On southbound Gregory Lane at Via Princessa. • On northbound May Way at Via Princessa. The stop signs have been already placed at the intersections to effect the appropriate right-of- way rule.
