ORAL COMMUNICATIONS FROM THE AUDIENCE - NONE III. OLD BUSINESS - NONE IV. NEW BUSINESS A. REQUEST FOR OVERNIGHT PARKING RESTRICTIONS ON HART AVENUE FROM MARSHALL STREET TO OLNEY STREET Traffic Engineering Deputy Itagaki presented the staff report RECOMMENDATION: There appears to be a need to allow parking during the day on Hart Avenue. However, during the evening hours, this need decreases as the office and health club clientele decreases. Therefore, it was recommended that "Tow Away No Parking 2:00 a.m. to 4:00 a.m." be installed on both sides of Hart Avenue from Marshall Street to Olney Street. ..This restriction will allow daytime parking and limit overnight parking. Speaking before the Commission was: Stacy Abajian Beacon Property Management Ms. Abajian stated that she agrees with the staff report and brought pictures of the motor home in question. Traffic Engineering Deputy Itagaki stated that she called Bally's Fitness Club regarding their hours, so that parking signs comply with business hours. Ms. Abajian asked if the City has an ordinance regarding people living in vehicles parked on public streets. Assistant City Manager Wagner stated that the City does not have "No Overnight Parking" ordinances. Ms. Abajian stated that if the City Council does not approve this item, they will pursue an appeal process for this traffic request. Commissioner Quintanilla asked if anyone has considered installing red curb. Traffic Engineering Deputy Itagaki stated that she would not recommend installing red curb up and down Hart Avenue, this would take away parking for the residents on that street. Commissioner Ruiz stated that he would like to see red curb installed, and a study done on "No Overnight Parking' ordinances, such as one established by the City of Temple City. Assistant City Manager Wagner stated that a ban on overnight parking has been discussed before the City Council, at which time the recommendation was not favored. It was moved by Commissioner Knapp, seconded by Commissioner Matsdorf, to approve the Traffic Engineer's recommendation. Vote Results: Yes: Chairman Baffo, Commissioner Knapp & Commissioner Matsdorf Noes: None Abstain: Commissioner Quintanilla & Commissioner Ruiz V. STAFF REPORTS - NONE VI. COMMISSIONER REPORTS - NONE VII. ADJOURNMENT There being no further business to come before the Commission, the meeting was adjourned at 7:35 p.m., with 4 people in the audience. The next regularly scheduled meeting is scheduled for June 6, 2002. Staff Report Rosemead Traffic Commission TO: HONORABLE CHAIRMAN AND MEMBERS ROSEMEAD TRAFFIC COMMISSSION na FROM: JOANNE ITAGAKI, TRAFFIC ENGINEERING DEPUTY l�P DATE: May 20, 2002 -\ RE: Request for Left Turn Phasing at Walnut Grove Avenue and Mission Drive REQUEST This request was originally brought before the Traffic Commission in February of last year. The agenda item and meeting minutes regarding this item are attached. At the February 2001 meeting, the intersection did not meet the guidelines for the installation of left turn phasing at Walnut Grove Avenue and Mission Drive. The Traffic Commission approved the staff recommendation not to install left turn phasing and re- examine the location in a year's time. Therefore, we have brought this item before the Commission for re- examination. CONDITIONS The conditions at the intersection of Walnut Grove Avenue and Mission Drive have not changed from last year. Walnut Grove Avenue is a 64 -foot wide north /south roadway through the City. There are two lanes of traffic in each direction separated by a double yellow centerline. There are northbound and southbound left turn lanes on Walnut Grove Avenue at Mission Drive. The posted speed limit on Walnut Grove Avenue is 40 mph. Mission Drive is a 64 -foot roadway generally traversing the City in an east/west direction. There are two lanes of traffic in each direction separated by a double yellow centerline. There are eastbound and westbound left turn lanes on Mission Drive at Walnut Grove Avenue. The posted speed limit on Mission Drive is 40 mph. Exhibit 1 depicts the general striping conditions at the intersection of Walnut Grove Avenue and Mission Drive. June 6, 2002 Traffic Commission Meeting Request for Left Turn Phasing at Walnut Grove Avenue and Mission Drive Page 2 of 5 DATA Last year, the reported accident history reviewed the period from January 1, 1997 through March 31, 2000. These accidents are depicted in Exhibit 2A. The reported accident history reviewed the period from April 1, 2000 through September 30, 2001. There were 6 additional reported accidents occurring at the intersection. These accidents are summarized below and depicted in Exhibit 2B. Description Time Day & Date 8. Eastbound stopped vehicle collided 8:20 AM Wed., 01/31/01 head -on with a westbound vehicle proceeding straight (P.C.F. = Vehicle did not yield right -of -way). 9. Westbound vehicle proceeding straight 3:30 PM Thurs., 06/14/01 broadsided a northbound vehicle proceeding straight (P.C.F. = Vehicle ran stop sign /signal). 10. Eastbound vehicle turning left broadsided 12:30 AM Tues., 08115/00 a westbound vehicle proceeding straight (P.C.F. = Vehicle made an improper turn). 11. Northbound vehicle turning left collided 6:10 PM Fri., 05/26100 head -on with a southbound vehicle proceeding straight (P.C.F. = Vehicle did not yield right -of -way). 12.Westbound vehicle proceeding straight 2:35 PM Wed.,'05 /31/00 broadsided an eastbound vehicle proceeding straight and a northbound stopped vehicle (P.C.F. = Vehicle made an improper turn). 13.Eastbound vehicle proceeding straight 4:50 PM Wed., 10/18/00 broadsided a westbound vehicle turning left (P.C.F. = Vehicle ran stop sign /signal). P.C.F. = Primary Collision Factor Turning movement counts were taken at Walnut Grove Avenue and Mission Drive during the AM and PM peak periods. The AM peak hour was found to be June 6, 2002 Traffic Commission Meeting Request for Left Turn Phasing at Walnut Grove Avenue and Mission Drive Page 3 of 5 7:30 — 8:30 AM. The PM peak hour was found to be 5:00 — 6:00 PM. The turning movement counts for 2001 and 2002 are depicted in Exhibit 3. A left turn delay analysis was also conducted at Walnut Grove Avenue and Mission Drive during the AM and PM peak periods. A delay analysis records the number of vehicles waiting in the left turn lane at the start of the green phase and then records the number of vehicles that turned left in the green phase. Exhibits 4A — 4D summarize the left turn delay analysis. DISCUSSION As we discussed last year, the installation of left turn phasing is based on guidelines presented in the Caltrans Traffic Manual. The Traffic Manual indicates that left turn phasing should be considered when one or more of the following conditions exist: 1. Accidents. Five or more left turn accidents for a particular left turn movement during a recent 12 -month period. 2. Delay. Left -turn delay of one or more vehicles which were waiting at the beginning of the green interval and are still remaining in the left turn lane after at least 80% of the total number of cycles for one hour. 3. Volume. At new intersections where only estimated volumes are available, the following criteria may be used. For a pretimed signal or a background - cycle- controlled actuated signal, a left turn volume of more than two vehicles per approach per cycle for a peak hour; or for a traffic - actuated signal, 50 or more left turning vehicles per hour in one direction with the produce of the turning and conflicting through traffic during the peak hour of 100,000 or more. (Even though this is not a new intersection, we will review this guideline for comparison purposes only). 4. Miscellaneous. Other factors that might be considered, include but are not limited to: impaired sight distance due to horizontal or vertical curvature, or where there is a large percentage of buses and trucks. Analysis of these four items was conducted at the intersection of Walnut Grove Avenue and Mission Drive for all directions (northbound, southbound, eastbound, and westbound). Northbound and Southbound Walnut Grove Avenue at Mission Drive 1. Accidents. During the 4 -3/4 years of reported accidents reviewed, only three reported accidents involved northbound or southbound left turning vehicles June 6, 2002 Traffic Commission Meeting Request for Left Turn Phasing at Walnut Grove Avenue and Mission Drive Page 4 of 5 (accidents number 1, 2 and 11). The first two accidents occurred in 1999 and the last accident occurred in 2000. This reported accident history does not meet the Caltrans guideline. 2. Delay. In reviewing the delay analysis, there were 5 cycles in which northbound or southbound left turn vehicles were delayed during the AM and PM peak periods studied. These cycles are circled on Exhibits 4A and 4C. From these 5 cycles, a total of 7 vehicles were delayed. The majority of vehicles approached the intersection on a green phase and completed their left turn in that phase. This does not satisfy the Caltrans guideline. 3. Volume. Turning movement counts indicate that 164 northbound vehicles turn left during the 7:30 — 8:30 AM peak hour (highest peak hour count). The opposing southbound through traffic volume is 613. The product of these counts is 100,532. This is satisfies to the Caltrans guideline of 100,000 or more. However, this guideline is used for new signal installations and was completed here for comparison purposes only. In addition, the accident history and delay analysis do not indicate a problem with northbound left turning traffic. For the southbound vehicles turning left, the highest peak hour volume was observed during the 5:00 — 6:00 PM peak hour at 90 vehicles. The opposing northbound through traffic volume is 558. The product of these counts is 50,220. This does not meet the Caltrans guideline of 100,000 or more. 4. Miscellaneous. Field observation of the intersection in the northbound and southbound directions does not indicate any usual condition. The north leg of the intersection "turns' slightly westerly beyond its intersection with Mission Drive. However, this horizontal curve does not affect the visibility of the traffic signal heads for southbound traffic. Eastbound and Westbound Mission Drive at Walnut Grove Avenue 1. Accidents. During the 4 -3/4 years of reported accidents reviewed, there were 3 reported accidents involving an eastbound or westbound left turning vehicle (accidents number 7, 10 and 13). The first accident occurred in 1998 and the last two accidents occurred in 2000. This reported accident history does not meet the Caltrans guideline. 2.. Delay. In reviewing the delay analysis, only 1 cycle in the eastbound or westbound direction was found to have delay (more vehicles waiting in the left turn pocket than get through on the green phase). This cycle is 'circled" on Exhibit 4A and occurs around 7:30 AM. This amount of delay does not meet the Caltrans guideline. June 6, 2002 Traffic Commission Meeting Request for Left Turn Phasing at Walnut Grove Avenue and Mission Drive Page 5 of 5 3. Volume. Turning movement counts indicate that the peak left turning volume in the eastbound direction is 44 vehicles in the 5:00 — 6:00 PM peak hour. The opposing westbound through traffic volume is 430. The product of these counts is 18,920. This does not meet the Caltrans guideline of 100,000 or more. For the westbound vehicles turning left, a volume of 185 vehicles was observed during the 7:30 — 8:30 AM peak hour. The opposing eastbound through traffic volume is 434. The product of these counts is 80,290. This does not meet the Caltrans guideline of 100,000 or more. 4. Miscellaneous. Field observation of the intersection in the eastbound and westbound directions does not indicate any usual conditions. The roadway alignment is straight with 'clear visibility of the traffic signal and on- coming traffic. RECOMMENDATION Based on the analysis presented above and the favorable accident history, the installation of left turn phasing in all directions of the intersection of Walnut Grove Avenue and Mission Drive is not recommended at this time.

Drive. . Commissioner Ruiz indicated he identified a need for left turn phasing especially in the peak hours. Upon considering Walnut Grove Avenue /Mission Drive for left turn phasing, - staff determined data should be collected to analyze all directions (northbound, southbound, eastbound and westbound) for left turn phasing installations. CONDITIONS Walnut Grove Avenue is a 64 -foot wide north /south roadway through the City. There are two lanes of traffic in each direction separated by a double yellow centerline. There are northbound and southbound left turn lanes on, Walnut Grove Avenue at Mission Drive. The posted speed limit on Walnut Grove Avenue is 40 mph. Mission Drive is a 64 -foot roadway generally traversing the City in an east/west direction. There are two lanes of traffic in each direction separated by a double yellow centerline. There are eastbound and westbound left turn lanes on Mission Drive at Walnut Grove Avenue. The posted speed limit on Mission Drive is 40 mph. Exhibit 1 depicts the general striping conditions at 'the intersection of Walnut Grove Avenue and Mission Drive. DATA The reported accident history for the intersection of Walnut Grove Avenue and Mission Drive was reviewed for the period from January 1, 1997 through March Request for Left Turn Phasing at Walnut Grove Avenue and Mission Drive Page 2 31, 2000. There were 7 reported accidents occurring at the intersection. These accidents are summarized below and on Exhibit 2: A Description Time Day & Date 1. Southbound vehicle proceeding straight 11:30 AM Sat., 03/13/99 broadsided a northbound vehicle turning left and an eastbound stopped vehicle (P.C.F. = Vehicle ran stop sign /signal). 2. Southbound vehicle turning left broadsided 6:35 PM Tues., 04/20/99 an eastbound vehicle proceeding straight (P.C.F. = Vehicle did not.yield right -of -way). 3. Eastbound vehicle proceeding straight 12:35 PM Thurs., 05/13/99 broadsided a northbound vehicle proceeding straight (P.C.F. = Vehicle ran stop sign /signal). 4. Southbound vehicle proceeding straight 1:15 PM Sun., 06/27/99 sideswiped a northbound vehicle proceeding straight (P.C.F. = Vehicle did not yield right -of -way/ Inattention of driver). 5. Southbound vehicle proceeding straight 10:15 AM Sat., 10/09/99 broadsided a westbound vehicle proceeding straight (P.C.F. = Vehicle ran stop sign /signal/ Inattention of driver). 6. Westbound vehicle making a U -turn. 1:00 PM Tues., 01/27/99 collided head -on with a southbound vehicle proceeding straight (P.C.F. = Vehicle making an improper turn). 7. Westbound vehicle turning left broadsided 12:25 PM Sat., 12/5/98 an eastbound vehicle proceeding straight (P.C.F. = Vehicle did not yield right -of- way). P.C.F. = Primary Collision Factor Turning movement counts were also taken at Walnut Grove Avenue and Mission Drive during the AM and PM peak periods. The AM peak hour was found to be 7:30 — 8:30 AM. The PM peak hour was found to be 5:00 — 6:00 PM. These counts are depicted on Exhibit 3. Q Request for Left Turn Phasing at Walnut Grove Avenue _ and Mission Drive Page 3 A left turn .delay analysis was also conducted at Walnut Grove Avenue and Mission Drive during the AM and PM peak periods. A delay analysis records the number of vehicles waiting in the left turn lane at the start of the green phase and then records the number of vehicles that turned left in the green phase. Exhibits 4A — 4D summarize the left turn delay analysis. DISCUSSION The installation. of left turn phasing is based on guidelines presented in the Caltrans Traffic Manual. The Traffic Manual indicates that left turn phasing should be considered when one or more of the following conditions exist: 1.. Accidents. Five or more left turn accidents for a particular left turn movement during a recent 12 -month period. 2. Delay. Left -turn delay of one or more vehicles which were waiting at .the beginning of the green interval and are still remaining in the left turn lane after at least 80% of the total number of cycles for one hour. 3. Volume. At new intersections where only estimated volumes are available, the following criteria may be used. For a pretimed signal or a background- cycle - controlled actuated signal, a left turn volume of more than two vehicles per approach per cycle for a peak hour; or for a traffic- actuated signal, 50 or more left turning vehicles per hour in one direction with the produce of the turning and conflicting through traffic during the peak hour of 100,000 or more. 4. Miscellaneous. Other factors that might be considered, include but are not limited to: impaired sight distance due to horizontal or vertical curvature, or where there is a large percentage of buses and trucks. Analysis of these four items was conducted at the intersection of Walnut Grove Avenue and Mission Drive for all directions (northbound, southbound, eastbound, and westbound). , Northbound and Southbound Walnut Grove Avenue at Mission Drive 1. Accidents. During the 3 -'/< years of reported accidents reviewed, only two accidents involving northbound or southbound left turning vehicles were reported (one northbound left turn - #1 and one southbound left turn - #2). Both these accidents occurred in 1999. However, this does not meet the Caltrans guideline. 2. Delay. In reviewing the delay analysis, there were no cycles in which northbound or southbound left turn vehicles were delayed during the AM and PM peak periods studied. The majority of vehicles approached the ,Jt Q� Request for Left Turn Phasing at Walnut Grove Avenue and Mission Drive Page 4 intersection on a green phase and completed their left turn in that phase. This does not satisfy the Caltrans guideline. 3. Volume. Turning movement counts indicate that 195 northbound vehicles turn left during the 7:30 — 8:30 AM peak hour (highest peak hour count). The opposing southbound through traffic volume is 483. The product of these counts is 94,185. This is close to the Caltrans guideline however it does not meet the guideline of 100,000. For the southbound vehicles turning left, the highest peak hour volume was observe d, during the 5:00 — 6:00 PM peak hour at 49 vehicles. The opposing northbound through traffic volume is 533. The product of these counts is 26,117. This does not meet the Caltrans guideline of 100,000. 4. Miscellaneous. Field observation of the intersection in the northbound and southbound directions does not indicate any usual condition. The north leg of the intersection "turns" slightly westerly beyond its intersection with Mission Drive. However, this horizontal curve does not affect the visibility of the traffic signal heads for southbound traffic. Eastbound and Westbound Mission Drive at Walnut Grove Avenue 9. Accidents. During the 3-% years of reported accidents reviewed, only one accident ( #7) reported involved an eastbound or westbound left turning vehicle. This accident occurred in 1998. However, this does not meet the Caltrans guideline. 2. Delay. In reviewing the delay analysis, only 3 cycles in the westbound direction were found to have delay (more vehicles waiting in the left turn pocket than get through on the green phase). These 3 cycles are "circled" on Exhibit 4A and occur around 8:00 AM. This amount of delay does not meet the Caltrans guideline. 3. Volume. Turning movement counts indicate that the peak left turning volume in the eastbound direction is 90 vehicles in the 7:30. — 8:30 AM peak hour. The opposing westbound through traffic volume is 784. The product of these counts is 70,560. This does not meet the Caltrans guideline of 100,000. For the westbound vehicles turning left, a volume of 190 vehicles was observed during the 7:30 — 8:30 AM peak hour. The opposing eastbound through traffic volume is 425. The product of these counts is 80,750. This does not meet the Caltrans guideline of 100,000. , 4. Miscellaneous. Field observation of the intersection in the eastbound and westbound directions does not indicate any usual conditions. The roadway Q�� Request for Left Tum Phasing at Walnut Grove Avenue , and Mission Drive - Page 5 - alignment is straight with clear visibility of the traffic signal and. on- coming traffic. RECOMMENDATION Based on the analysis presented above and the favorable accident history, the installation of left turn phasing in all directions of the intersection of Walnut Grove Avenue and.Mission Drive is not recommended at this time. It appears that the volume of traffic on Walnut Grove Avenue may, in the future, increase to a point where left turn phasing may be required. Therefore, staff will re- evaluate this location in a year's-time.
