CC - Item 4B - Staff Report - Installation of Additional Traffic Controls on Marshall Street at Vane Avenue %O 7'1 * �� % p staffeport TO: HONORABLE MAYOR AND MEMBERS ROSEMEAD CITY COUNCIL FROM: FRANK G. TRIPEPI, CITY MANAGER 7l/ DATE: FEBRUARY 18, 1998 RE: INSTALLATION OF ADDITIONAL TRAFFIC CONTROLS ON MARSHALL STREET AT VANE AVENUE This item was continued at the regular meeting of February 10, 1998. In response to the City Council's request for additional information about the vehicle accident occurring at the intersection of Marshall Street and Vane Avenue in January 1997, staff has attached a memorandum from the City's Traffic Engineer explaining the details. In summary,the accident occurred in the early hours of the morning and was attributed to an improper turn made by the driver. As a result of that incident and other observations at the intersection, the Traffic Engineer and Traffic Commission originally recommended the installation of an R-1 "Stop" sign on eastbound Marshall, at Vane. The Traffic Commission originally considered this item at the request of a local resident who was concerned about vehicles "cutting the turn too short"when entering Vane Avenue from westbound Marshall. The resident requested that R-1 "Stop" signs be placed at all corners of the intersection to alleviate the problem. Upon examining the issue, the Traffic Engineer determined that "Stop" signs at all corners would not meet established traffic and/or accident warrants for multi-way"Stop" controls at the intersection. The recommendation, however, did include an R-1 "Stop" control on eastbound Marshall, at Vane, as a method of limiting potential vehicle conflicts at the intersection. On February 10, 1998, some members of the Council stated objections to the original recommendation to install a"Stop"sign at that location. In recognition of those concerns,the Traffic Engineer, recommends the following: • Installation of a double yellow centerline on Vane Avenue for a distance of 75-feet south of Marshall Street; COUNCIL AGENDA FEB 241998 ITEM No. �. e e--- g 2 MarshallNane Traffic Markings February 18, 1998 Page 2. • Removal of the existing Type N marker on the fence of the school located at the west terminus of Marshall Street and replacement of that sign with a red W31 "End" sign installed behind the curb at that location; • Relocation of the"Stop"and limit line markings on Vane Avenue,south of Marshall. The Traffic Engineer has concluded that the installation of the double yellow centerline on Vane will serve to direct motorists from Marshall Street to Vane avenue without "cutting the turn too sharp." In addition, the relocation of the signs will alert motorists traveling westbound on Marshall that the street does, for all intents and purposes, end at Vane Avenue. A copy the memorandum and revised sketch (Exhibit A) from the Traffic Engineer, as well as the original staff report from February 10, 1998, have been attached for the Council's review. RECOMMENDATION: Staff recommends that the City Council approve the installation of a double yellow centerline on Vane Avenue, revised W31 "End" markings and relocation of the"Stop"and limit lines on Vane Avenue, as detailed in Exhibit A. amemovane-mar fgi 06717/NSOVL10IM%3/LSZBIHr\' I— m _ C/{' >c W X co ,81 ,8I co U LU 1 1 p H w I c C In I C LIJ OJ W ? z Z Q > H- Q ' X JI— E N J 05) 5 (3 .z W X f C W W 0 J n N Z I — o Cr)J J T T f 1 f 1 __ __ __ ��pp �L .

TRIPEPI, CITY MANAGER FROM: JOANNE ITAGAKI, DEPUTY TRAFFIC ENGINEER DATE: FEBRUARY 12, 1998 RE: COUNCIL FOLLOW-UP TO MARSHALL STREET AND VANE AVENUE As requested by Councilmember Taylor, I have obtained additional information regarding the reported accident at the intersection of Marshall Street and Vane Avenue referenced in the staff report. The following is a summary of the accident: Date and Time January 25, 1997 1:00 a.m. Location On Marshall Street 150 feet south of Vane Avenue Description A southbound vehicle proceeding straight rearended a parked vehicle. The primary collision factor of this accident was identified as an "Improper Turn". Based on the primary collision factor and the direction of travel, it appears the southbound vehicle turned from Vane Avenue onto Marshall Street and struck a parked vehicle. Should the Council determine the installation of a STOP control for eastbound Vane Avenue at Marshall Street inappropriate, I would revise the proposed centerline striping. I would recommend the installation of the double yellow centerline for a distance of 75 feet as shown on the attached Exhibit A. This centerline striping will direct motorists to turn from Vane Avenue to Marshall Street without cutting the turn "too sharp". I would continue to recommend the removal of the existing Type N marker on the fence of the school. This marker is inappropriately installed. The existing Type N marker should be replaced with a red Type N marker and a W31 "END" sign installed behind the curb. This recommendation is also shown on Exhibit A. Please feel free to contact me if you have any questions regarding this matter. Attachment TO: HONORABLE MAYOR AND MEMBERS ROSEMEAD CITY COUNCIL FROM: FRANK G. TRIPEPI, CITY MANAGER DATE: FEBRUARY 4, 1998 RE: STOP SIGNS ON MARSHALL STREET AT VANE AVENUE At the regularly scheduled November 1997 Traffic Commission meeting, the Commission considered a request from a resident to install R-1 Stop signs on Marshall Street at Vane Avenue. The resident stated that vehicles traveling westbound on Marshall Street often turn left onto Vane Avenue after realizing that the roadway on Marshall ends just west of the intersection. As a result, the vehicles tend to "speed" around the corner and "cut the turn too short" The Commission considered the request and approved additional traffic controls at the intersection. CONDITIONS Marshall Street is a 36-foot wide east/west residential roadway. There are no stripes on the roadway. Marshall Street ends approximately 150-feet west of Vane Avenue. There is a back access to Savannah School at the cul-de-sac located on the west end of the Marshall Street. Marshall Street is STOP controlled at its intersection with Ellis Lane. The prima facie speed limit is 25 MPH on Vane Avenue. Figure 1 depicts the conditions at the intersection of Marshall Street and Vane Avenue. DATA The traffic accident history for the area was obtained from Temple Sheriffs Station. The reported accident history was reviewed for the period covering January 1, 1996 through October 20, 1997. A review of the history revealed only one accident as being reported at the intersection of Marshall - Street and Vane Avenue during that period. That accident occurred on Saturday, January 25, 1997 at 1:00 a.m. The primary collision factor for the accident was listed as an "Improper Turn"" COUNCIL AGENDA FEB 101298 ITEM No. Z et-D Traffic Controls -MarshallNane February 4, 1998 Page 2. Traffic volume counts were taken on Marshall Street between Vane Avenue and Marybeth Avenue and on Vane Avenue,just south of Marshall. The counts were taken on Wednesday, October 8, 1997 and revealed the following: Direction 24-hour Volume Eastbound Peak Hour Volume 177 30 (2:00 p.m.) Westbound 473 Northbound 75 (5 30 am.) 270 28 (5:30 p.m.) Southbound 272 39 (7:45 am.) DISCUSSION the purpose of STOP controls is to assign right-of-way. The basic STOP control is typically assigned to the street with the least volume of traffic. Beyond this basic level of control, multi-way control is applied to locations where traffic counts on each roadway are nearly equal and heavy enough to require rotation of right-of-way in order to minimize delay and reduce congestion. The intersection at Marshall Street and Vane Avenue has a relatively low volume of traffic traveling through the intersection. Approach volumes to the intersection are not "nearly equal." The primary approach is in the westbound direction (423 vehicles each day). The Caltrans Traffic Manual provides guidelines (attached) for the installation of multi-way STOP controls. The first, guideline deals with the immediate need for traffic signals at the location, and that does not apply in this case. The second guideline regarding accidents is not met in this case. More than five (5) during the course of year is the standard to be met. And, the third guideline is not met either. To meet that standard,traffic volumes must exceed 500 vehicles per hour during any eight (8)hour period. Clearly, those volumes do not occur at the intersection. Pursuant to the Caltrans guidelines, the installation of multi-way STOP controls at the intersection of Marshall and Vane is not recommended. However, the Traffic Commission affirmed the staff recommendation to install a STOP sign for eastbound Marshall Street at Vane and for the installation of"double yellow'striping on Vane, south of Marshall. Those controls would serve to establish the major movements at that location - westbound traffic on Marshall turning left onto Vane, and a smaller amount of traffic turning right onto Vane from Marshall Street. In short, it is the Traffic Engineer's opinion that it is best to limit potential vehicle conflict at the intersection by STOP controlling the eastbound traffic from the cul-de-sac that makes a right turn from Marshall onto Vane. In addition, staff believes that the installation of the "double yellow" striping will assist in guiding drivers making left turns from Marshall onto Vane. The recommendations are outlined in Figure 1. Traffic Controls -Marshall/Vane February 4, 1998 Page 3. RECOMMENDATION: Staff recommends that the City Council take the following action: 1. Install an R-1 STOP sign for eastbound Marshall Street at Vane Avenue. 2. Relocate the STOP and limit line markings on Vane Avenue, south of Marshall Street. 3. Install a double yellow centerline on Marshall Street and Vane Avenue and in the turn, westbound to southbound. 4. Remove the existing "Type N" marker on the fence and install a red "Type N" sign with appropriate markings behind the curb at the western terminus of the Marshall Street cul- de-sac.

ROLL CALL Present: Chairman Ruiz Commissioners: Tirre, Knapp, Quintanilla, Baffo Absent: None Ex Officio: Administrative Aide: Cecilia Gallardo Deputy Traffic Engineer: Joanne Itagaki CALL TO ORDER The Pledge of Allegiance was led by Commissioner Quintanilla The Invocation was delivered by Commissioner Knapp I. APPROVAL OF MINUTES It was moved by Commissioner Tirre, seconded by Commissioner Baffo, and carried unanimously to approve the minutes for October 2, 1997. II. ORAL COMMUNICATIONS FROM THE AUDIENCE - NONE III. OLD BUSINESS - NONE IV. NEW BUSINESS A. REOUEST FOR STOP SIGNS ON MARSHALL STREET AT VANE AVENUE Deputy Traffic Engineer Itagaki stated that this request came from Ms. Christine Callen, 3639 Vane Avenue, for the installation of STOP signs on Marshall Street at Vane Avenue. Ms. Callen had indicated that westbound vehicles on Marshall Street turn left onto Vane Avenue when they realize the roadway ends west of Vane Avenue. These vehicles are "speeding" around the corner and "cut the turn too short". Marshall Street is a 36-foot wide east/west residential roadway. There are no strips on the roadway. Marshall Street ends approximately 150 feet west of Vane Avenue. There is back access to Savannah School in this cul-de-sac of Marshall Street. Marshall Street is STOP controlled at its intersection with Ellis Lane. The prima facie speed limit on Marshall Street is 25 mph. Vane Avenue is also a 36-foot wide residential roadway. Vane Avenue is STOP controlled at its intersection with Marshall Street and Olney Street (to the south). The intersection of Vane Avenue and Marshall Street is a T-intersection. The prima facie speed limit is 25 mph on Vane Avenue. Traffic accident history was obtained from the Temple Sheriffs Station. The reported accident history was reviewed for the period from January 1, 1996 through October 20, 1997. Review of the reported accident history revealed only one accident reported at the intersection of Marshall Street and Vane Avenue. This accident occurred on Saturday, January 25, 1997 at 1:00 a.m. The primary collision factor reported for this accident was "Improper Turn". The purpose of STOP controls is to assign right-a-way. The basic STOP control is typically assigned to the street with the least volume of traffic. Beyond this basic level of control, multi-way control is applied to locations to where traffic on each roadway is nearly equal and heavy enough to require the rotation of right-a-way in order to minimize overall delay and reduce congestion. The intersection of Marshall Street and Avenue has a relatively low volume of traffic traveling through the intersection. Approach volumes to the intersection are not"nearly equal". The primary approach is in the westbound direction (423 vehicles per day). The first guideline deals with the immediate need for traffic signals at a location. This does not apply to the intersection of Marshall Street and Vane Avenue. The second guideline is satisfied if 5 or more accidents are reported within a 12-month period. The reported accidents at this intersection of Marshall Street and Vane avenue revealed only one accident within almost a 2 year period. The third guideline is satisfied when the approach volumes to the intersection are 500 vehicles per hour for any 8 hours. The traffic volumes on Marshall Street and Vane Avenue do not approach this guideline. 2 The installation of STOP controls on Marshall Street are not recommended. It is likely that an all-way stop intersection installed at Marshall Street and Vane Avenue would be disregarded due to the minor traffic volumes on the street and the cul-de-sac of Marshall Street. The concern expressed by Ms. Callen was for speeding and vehicles making the left turn too sharp. This indicates a need for positive direction of the vehicles on Marshall Street. In addition, the one accident reported was caused by an improper turn. RECOMMENDATION: To provide positive direction and handle the volume of traffic traveling through the intersection, the following measures are recommended: 1. Installation of STOP sign for eastbound Marshall Street at Vane Avenue. 2. Relocation of STOP and limit line markings southerly on Vane Avenue. 3. Installation of double yellow centerline on Marshall Street and Vane Avenue and in the turn (westbound to southbound). 4. The removal of the existing marker on the fence. These recommendations will: 1. Stop the minor traffic volumes from the cul-de-sac of Marshall Street. 2. Direct vehicles around the westbound to southbound left turn reducing the number of vehicles "turning too sharp". Commissioner Knapp would like to include on the double center line going around the curb, the raised reflector dots as part of the direction for nighttime travel. It was moved by Commissioner Knapp, seconded by Commissioner Baffo, and carried unanimously to approve the Traffic Engineer's recommendation, with the addition of the raised reflector dots. STAFF REPORTS Administrative Aide Gallardo stated that this would be her last meeting, as she has accepted a job with the City of Rancho Cucamonga. 3 VI. COMMISSIONER REPORTS Commissioner Knapp stated that she has concerns regarding the new Burger King, she sees a lot of potential for traffic problems at this location and would like staff to consider the raised reflector dots at this location. Commissioner Tirre asked if there was a sign on Garvey and Rosemead Place, going north for trucks parked on residential streets. VII. ADJOURNMENT There being no further business to come before the Commission, the meeting was adjourned. 4
