SCHOOL PEDESTRIAN OPERA'T'IONSISAFETYSTDDY FOR TIE YIVTERSECTION OF
9.I OAK BLUFF LANE / NEWFIELDS LANE.
This report presents the findings of a pedestrian crossing study for the intersection of Oak Bluff Lane at .
Newfields Lane in the City of Dublin, CA. The study was conducted in order to identify existing
conditions when children are traveling to/from school and potential measures to facilitate their travel,
including monitoring by adult crossing guards and/or improvements to the intersection design.
Overall Intersection Description
The Oak Bluff Lane /Newfields Lane intersection is located approximately 200 feet east of the Oak Bluff
Lane /North Dublin Ranch intersection. It borders the north side of Ted Fairfield Park and the John
Green Elementary School grounds. It is a T-shaped intersection (3-legs) with Oak Bluff Lane oriented in
an east-west direction and Newfrelds Lane extending north (see Figure 9.1). The intersection is stop sign
controlled for the Newfields Lane approach. Both streets are primarily residential, but Oak Bluff Lane
also provides access to the school's entrance via Bridgepoint Lane. A pedestrian path goes to the park
and school from the Newfields Lane intersection. Each street consists of two travel lanes with on-street
parking allowed and 25 miles per hour.speed limit.
Pedestrian facilities at the intersection consist of a white painted crosswalk across Oak Bluff Lane on the
east side of the intersection (no crosswalk on the west side). The Newfields Lane approach has a painted
stop-line. There are sidewalk facilities on both streets. The pedestriarr path extends south from Oak Bluff
Lane near the crosswalk. Field observations noted that a number of motorists park along Oak Bluff Lane
near the intersection to drop off and pick up children who access the school from the trail.
Pedestrian-Bicycle Volumes Summary
The peak hour pedestrian volumes were counted and are illustrated in Figure 4.2. During the morning
peak hour, there were 51 pedestrians (27 adults, 24 children) across Oak B1uffLane and 14 pedestrians (8
adults, 6 children) across Newfields Lane. During the afternoon peak hour, there were 36 pedestrians (18
adults, 17 children, 1 child bike) across Oak Bluff Lane and 5 .pedestrians (3 adults, 2 children) across
Newfields Lane.
(Pedestrian volumes were also counted across a marked crosswalk located just east of Sugarloaf Court
located approximately 300 feet east of Newfields Lane. The pedestrian volumes were.very low, consisting
of zero in the morning and two adults in the afternoon peak hour.)
Traffic Volume-LOS Summary,
Vehicle traffic volume counts were also conducted during the peak hours (refer to Figure 9.2). The total
intersection volumes were .114 in the morning and I22 in the afternoon peak hour. .The number of
vehicles through. the Oak Bluff Lane crosswalk was 86 in the morning and 92 in the afternoon. The
Newfields Lane crosswalk experienced 55-58 vehicle trips in the peak hours.
Conditions for drivers at an intersection are measured by Level of Service (LOS), which applies.a letter
ranking to successive levels of intersection performance. LOS `A' represents optimum conditions with
free-flow travel and no congestion. .LOS `F' represents severe congestion with long delays at the
approaches. (LOS definitions and calculations are provided in the Appendix.) For intersections witli

minor-street stop control, .the LOS reflects delays: experienced by the- stopped approach. The intersection
operates at LOS A conditions during the AM peak hour and the afternoon peak hour.
The intersection operates efficiently in terms of vehicle delays.' ;However, during the peak periods of
morning~and afternoon school activity, drivers.park along both sides of Oak Bluff Lane to drop off /pick .
up children who use the pedestrian path to/from school.. During the busiest 20-30 minutes, there is a
fairly busy combination of vehicle .traffic, parking maneuvers, and pedestrian crossing -activity
concentrated at the intersection.
Sight Distances
Outside of the . schooi pick-up and drop-off periods, sight distances are unobstructed and reach to
approximately 300 feet. During school-related parking activity, the sight. distances can be reduced to 75-
100 feet from the edge of the sidewalks. Field observations counted .15-20 cars temporarily parked along
Oak Bluff Lace in the morning and afternoon peak periods. The number of cars parked outside 'of the
peak periods appears to be very low, unless there is an athletic event at the .park (six to ten vehicles were
observed parked along Oak Bluff Lane in the late afternoon for a soccer game.)
The sight distances were measured and compared to recommended guidelines as defined in the California
Department of Transportation (Caltrans) Highway Design•Manual for the uncontrolled Oak Bluff.Lane
crosswalk. One guideline is referred to as "stopping" sight distance, which is defined as the distance
required by the driver of a vehicle traveling at a given speed to bring-the vehicle to a stop after. an object
on the road becomes visible. The sight distance guidelines are based on the travel speeds of approaching
vehicles (higher speeds require longer stopping distance). 'Based on the 25 mph speed limit (measured
85~'-percentile speeds were lower than 25 mph during the peak hours), the stopping sight recommendation
is 165 feet. Therefore, the sight distances exceed the recommendations.
Accident History
The recorded accident history is the source used by transportation engineers in assessing an' area's
accident history: An area may have unrecorded accidents in addition to the recorded ones. However,
unrecorded accidents cannot be scientifically evaluated. Based on the City's records, there were no
recorded accidents for the five year period from 2003 through 2007 at the intersection.
Crossing Guard Summary-Findings
This intersection is not monitored by a crossing guard.
Guidelines to assist in determining whether to use crossing guard monitoring are provided by the
California Manual on Uniform Traffic Control Devices (CaMU'TCD}.1 The guidelines for crossing guards
state the following:
"Adult crossing guards normally are assigned where official supervision of school pedestrians is desirable
while they cross a public highway, and at least 40 school pedestrians for each of any two hours (not
necessarily consecutive} daily use the crossing while going to or from school."

Streets and HiahwaYs; Federal Highway Administration MUTCD 2003 Edition, as amended for use in California.

With an elementary-age pedestrian volume of 24 in the morning and 18 in the afternoon, the pedestrian
volumes do not meet the guidelines for crossing guards. .
Other factors to consider are the concentration of vehicle traffic and on-street parking maneuvers near the
intersection during the peak 20-30 minutes of school activity. At such times,.sight distances are reduced.
at the crosswalks.
o The combination of pedestrian volumes and increased activity during peak school periods suggest
monitoring by a crossing guard could be considered.
In .addition to the crossing guardwarrants, other improvements to enhance pedestrian crossings were
examined. ('Z'he existing and potential signing near the intersection are illustrated in Figure 4.3.)
Current installations at other school locations in the City are primarily derived from the Caltrans Traffic
Manual's (1996) guidelines. The Traffic Manual recommendations have been superseded by the
CaMiJTCD (2006) guidelines for new installations. However; both documents emphasize maintaining
uniformity in the field. Therefore, new installations could follow the existing format in order to remain
consistent with other school zones in Dublin.
• Paint a marked crosswalk across the Newfields Lane approach to the intersection. This would
help pedestrians crossing Newfields Lane by moving the stop Line for approaching vehicles
further away from the intersection.
Given the intersection's proximity to the school, guidelines foi crosswalk markings within school zones
were examined. The guidelines state:
"A marked pedestrian crosswalk may be yellow if the nearest point of the crosswalk is not more
than 600 feet from a school building or school grounds. (Refer to CA Vehicle Code 2I368)."
Or:. "A marked pedestrian crosswalk may be yellow if the nearest point of the crosswalk is not
more than 2,800 feet from a school building or grounds and there are no intervening crosswalks, other than
those contiguous to the school grounds, and it appears that the facts and circumstances require special
marking for the protection and safety of persons attending the school. (Refer to CA Vehicle Code
21368.)" (CA MUTCD, p. 7C-2).
• The Oak Bluff Lane / Newfields Lane intersection is located approximately 300 feet from the
western boundary of the school grounds and is about 600 feet from. school buildings via the path
-through Ted Fairfield park. The .intersection.is located close enough fo the school that the
crosswalks .could be painted yellow. Additionally, the Oak Bluff Lane crosswalk could be
marked with longitudinal lines for greater visibility. _
• Signing consistent with the City's policies and/or the CaMITTCD guidelines could be installed to
supplement the :Oak Bluff Lane crosswalk.,- .These include crosswalk warning assemblies in
advance ~of arid at the Oak Bluff Lane crosswallc,.as well as " 25 mph Speed Limit" signs'in both
directions. -
• Additionally, an in-street Type Rl-6 "Yield to Pedestrians in'Crosswalk" sign could be installed
in the Oak Bluff Lane crosswakc.

i ~ ~• . ' ,Pavement markings could be installed for both directions of travel on Oak $Iuff Lane in advance
of the crosswalk that state, "Slow School Xing".
Parking could lie restricted near the intersection. by painting the cubs red in order to provide
increased sight distances for crossing pedestrians. Beginning from the brosswalk, eastbound Oak
.Bluff Lane could be red-curbed for approximately 75 feet to the west and 20 feet to' the east .
Westbound Oak Bluff Lane could be red-curbed for approximately 50 feet to the east. (This is
similar to existing conditions at the Antone Way / Grafton Street intersection.) Field observations
indicated low parking demand outside of the school activity periods~and there is substantial curb
space available for parking. .Therefore, parking prohibitions near the intersection would not
impact existing parking conditions.
