DESCRIPTION:
Both Public Works and Dublin Police Services (DPS) have received requests from businesses
and residents to improve pedestrian safety at the existing mid -block crosswalk between
Regional Street and Starward Drive (Figure 1 below). Safety requests included consideration of
minimizing vehicle and pedestrian conflicts, and improving driver visibility of the crosswalk itself
and pedestrian visibility in both directions along Amador Valley Boulevard. The proposed project
is designed to address the above stated concerns.
Amador Valley Boulevard is, at the proposed project location, a 4 -lane Class I Collector with a
raised concrete median, left -turn pockets and bicycle lanes. The crosswalk is about 380 feet
from the signalized intersections of Regional Street and Starward Drive. There are adjacent
commercial driveways on both sides of the street at the crosswalk, forming a side - street stop -
controlled type of intersection. The posted speed limit on Amador Valley Boulevard is 30 miles
per hour, and average weekday daily traffic volumes are about 16,000 vehicles.
Figure 1
There are existing advanced pedestrian warning signs near the Starward Drive and
Regional Street intersections over 300 feet from the crosswalk, as well as signs at the
intersection. Curb ramps and tactile domes are present at the crosswalk.
ANALYSIS
Staff contracted with a traffic consultant, Fehr & Peers, to conduct a safety audit (Attachment 1)
using a crosswalk treatment identification tool to evaluate the existing crosswalk and to consider
potential improvements to better accommodate pedestrians. The tool combines academic
research on crosswalk treatment effectiveness with national best practices. Key inputs for the
tool include:
1. speed limit
2. pedestrian volume
3. major and minor roadway volumes
4. crossing distance
5. number of lanes
Page 2 of 5
6. presence of bicyclists
7. presence of transit
8. presence of a median
9. presence of on- street parking
10. expected motorist compliance (yielding)
Based on the analysis of the above listed factors and field observations, Fehr & Peers
recommended, and Staff concurs, that the following improvements be implemented to improve
pedestrian safety at this location:
Pedestrian Actuated Devices
Installation of Rectangular Rapid Flashing Beacons (RRFBs) was identified as a measure by
the crosswalk treatment identification tool. RRFBs are user - actuated amber LEDs that
supplement warning signs. They use an irregular flash pattern and have been found to increase
motorists' yield rates at an uncontrolled crosswalk to approximately 80 percent and can be more
effective when implemented with other treatments, such as signing and striping improvements
discussed below. Staff also considered the installation of in- pavement flashers (In Pavement
Lights), but it was not recommended due to the east /west alignment and intersection visibility
issues.
Sianina and Strinin
Although the crosswalk is currently signed and striped appropriately, it is recommended to
enhance pavement markings and signage in advance of and at the crosswalk. Advance yield
markers for westbound and eastbound traffic (i.e. Shark's teeth approximately 30 feet in
advance of crosswalk, Figure 2) should also be installed. These should be paired with
additional signage.
Striping advanced stop bars at both driveways at this location is also recommended. All existing
pavement markings and signs at the driveways should be refreshed and /or replaced.
Driveway Aprons:
The existing Driveway apron on the southerly driveway should be modified to improve
pedestrian circulation and to improve Americans with Disability Act (ADA) access. This will
require adjacent property owners /businesses support in acquiring construction easements
during the construction of the driveway. Rebuilding of the driveway will entail creation of
sufficient space to mark an 8 -foot crosswalk and to comply with the ADA standards.
Turn Restrictions
Reducing the number of conflict points across the crossing will improve the pedestrian
safety. To accomplish this, construction of a partial median on Amador Valley Boulevard is
recommended. It would reduce the vehicle /pedestrian conflict points at the crossing by
restricting turn movements from the retail centers across the crosswalk. It should be noted
that each shopping center associated with the north and south Retail Driveways has a
significant number of additional access points for motorists, including a signalized full
access entrance at the intersection of Amador Valley Boulevard /Regional Street for the
northern center. The southern shopping center has numerous side - street stop - controlled
driveways along Amador Valley Boulevard, Regional Street, and Dublin Boulevard. Traffic
operations under the existing and restricted access conditions were evaluated and staff found

no significant impacts on traffic delays at the existing signals at Regional Street or Starward
Drive, and the retail driveways on Amador Valley Boulevard or Regional Street.

RECOMMENDATIONS AND CONCLUSIONS
Based on staff and Fehr and Peers analysis of the mid -block crosswalk on Amador Valley
Boulevard between Regional Street and Starward Drive, it is recommended that the following
improvements be implemented:
1. Install an advance yield markers for westbound and eastbound traffic 30 feet in advance
of crosswalk, including "YIELD HERE TO PEDESTRIANS" signs
2. Reconstruct southern commercial driveway to meet ADA standards and provide space
for a crosswalk
3. Install advance stop bars at the commercial driveways and new stop signs
4. Install a pedestrian actuated RRFB system and coordinate it with the advanced beacon in
the eastbound direction
5. Reduce conflicts at the crosswalk by partially extending the median and restricting
turning movements, as presented in Figure 2
Project Costs and Next Steps
Pending the City Council approval, Public Works will contract with Fehr and Peers, current on-
call consultants, to complete the design of the project. This task budget is estimated at $27,300.
Staff salaries are estimated at $13,272. The overall construction cost is estimated at $137,653,
Page 4 of 5
and Staff plans to secure a construction contract through the formal bidding process for this
work during Fiscal Year 2013/14.
The City Council is also being asked to approve the proposed resolution (Attachment 3)
requesting that the Metropolitan Transportation Commission (MTC) allocate Transportation
Development Act Article 3 funds to this project.

MEMORANDUM
Date: October 30, 2012
To: Obaid Khan, City of Dublin
From: Kathrin Tellez, Fehr & Peers
Fehr & Peers conducted a crosswalk audit of a mid -block crossing on Amador Valley Boulevard
between Regional Street and Starward Drive (Crossing) in Dublin. The Crossing is shown on
Figure 1 (all figures are at the end of this report). The main function of a crosswalk is to
channelize pedestrians. Well- marked pedestrian crossings accomplish dual goals. They prepare
drivers for the likelihood of encountering a pedestrian, and they create an atmosphere of
walkability and accessibility for pedestrians. Marked crossings reinforce the location and
legitimacy of a crossing.
For this assessment, Fehr & Peers collected data to evaluate the current condition, conducted a
walking audit with City and Police staff, and evaluated potential crosswalk treatments.
EXISTING CONDITIONS
The Crossing is located on Amador Valley Boulevard, a 4 -lane Class I Collector with a median, left-
turn pockets and bicycle lanes. The crossing is about 380 feet from the signalized intersections of
Regional Street and Starward Drive, as shown on Figure 2. There are adjacent driveways on both
sides of the street at the Crossing, forming a side - street stop - controlled intersection. The posted
speed limit is 30 miles per hour, and
average weekday daily traffic volumes are
about 16,090. Attachment 1 summarizes
relevant information used in this
assessment.
The roadway design creates a multiple -
threat condition on both approaches. A
multiple- threat condition can occur on any
multi -lane roadway where pedestrians
must cross more than one lane of travel in
a given direction. When a single motorist
yields to the pedestrian close to the
crossing, additional approaching motorists
may not interpret correctly the reason the

first motorist stopped and may not see the pedestrian as they walk into the second lane into the
path of the oncoming vehicle. This condition is particularly acute on the westbound approach
with its left -turn lane. A vehicle that is stopped in the left -turn lane may be waiting for a
pedestrian to cross the street or for a gap in traffic to make the left -turn movement. A vehicle in
the through lane may not see a pedestrian blocked by the left -turn vehicle.
In addition, sight lines are limited at the Crossing due to the horizontal roadway curvature.
Signals become visible just as motorists approach the Crossing, and if the light is green, motorists
may be encouraged to speed up or less inclined to yield to pedestrians so that they can make the
light.
There are advanced pedestrian warning signs near the Starwood
Drive intersection and Regional Street intersection, over 300 feet
from the crossing, as well as signs at the intersection. Curb ramps
and tactile domes are present at the crosswalk.
Pedestrians have been observed running across the street at the
Crossing to avoid on- coming traffic and the Dublin Police
were two reported pedestrian /vehicle accidents which resulted in
injuries to the pedestrian. Based on complaints to the Police and City
staff, there have been numerous near - misses at the Crossing. While
there were no pedestrian - related accidents in 2010, there was one in
2011 resulting in injury.
ANALYSIS
Fehr & Peers used a crosswalk treatment identification tool to evaluate the existing Crossing and
to consider potential improvements to better accommodate pedestrians. The tool combines
academic research on crosswalk treatment effectiveness with national best practices. Key inputs
for the tool include:
• speed limit
• pedestrian volume
• major and minor roadway volumes
• crossing distance
• number of lanes
• presence of bicyclists
• presence of transit
• presence of a median
• presence of on- street parking
• expected motorist compliance (yielding)
Attachment 1 summarizes these inputs. Based on current conditions, the pedestrian condition is
poor. Given conditions of the Crossing, located on a multi -lane street (three or more lanes) with

traffic volumes exceeding 16,000 vehicles per day, enhanced treatments beyond current striping
and signing are appropriate. Crosswalk removal is not recommended because the Crossing is
located more than 300 feet from adjacent crossings. Because of the separation between adjacent
signalized crossings, pedestrians would be likely to continue crossing at this location despite a
prohibition.
RECOMMENDATIONS
The following details our recommended Crossing improvements.
Pedestrian Actuated Devices
crosswalk treatment identification tool. RRFBs are user - actuated amber LEDs that supplement
warning signs. They use an irregular flash pattern and have been found to increase yield rates at
uncontrolled crossings to approximately 80 percent and can be more effective when implemented
with other treatments, such as signing and striping improvements discussed below. Per CA
MUTCD interim approval guidance, RRFBs would be placed on the right and left sides of the
roadway immediately adjacent to the crosswalk, with a double -sided RRFB unit located in the
median. RRFBs may also be combined with advanced warning sign or advanced beacons, located
approximately 150 feet before the RRFB devices.
Based on the Crossing location, full signalization is not recommended due to the close spacing of
the crosswalk to the adjacent traffic signals. Installation of in- pavement flashers is not
recommended due to the east /west alignment and visibility issues.
Signing and Striping
Although the Crossing is currently signed and striped appropriately, there is an opportunity to
modify the current placement of signs and add additional pavement markings. Additionally,
some of the existing signage is faded and outdated. The current pedestrian signing is located
approximately 380 feet from the crossing when traveling in the eastbound direction and 220 feet
from the crossing when traveling in the westbound direction. It is recommended that the sign on
the south side of the street, for eastbound vehicles, be moved closer to the crossing,
approximately 190 feet from the crosswalk and include an advanced beacon. This location
considers the location of a driveway serving the shopping center.
feet in advance of crosswalk)
crosswalk and the R1 -5L signs at the markings has been shown to reduce multiple- threat
collisions and reduce auto /pedestrian conflicts. When advanced yield markers are placed 30 to 50
feet in advance of a crosswalk on a multi -lane roadway, the yielding motorist does not obscure
the view of a pedestrian crosswalk. Though advanced yield markings may be staggered by travel
lane, research has proven effectiveness at a uniform 30 to 50 feet distance from the crosswalk. At
areas with complex roadway geometry or demonstrated sight distance issues, staggered
advanced yield markings may be appropriate.

Striping advanced
stop bars at both
driveways is
recommended.
Advanced stop
bars are typically
placed 4 to 10 feet
from a crosswalk,
instructing drivers
to stop before the
crosswalk, preventing encroachment into the crosswalk area. If the crosswalk is clear of
pedestrians, drivers may then advance to the intersection where they can look for conflicting
traffic before turning to the main street. The northern driveway provides a level pedestrian path
through the driveway due to the steep driveway apron. An advanced stop bar is recommended at
this location to prevent cars from encroaching into that level pedestrian path. The southern
driveway is level with the roadway, similar to a typical intersection. However, a wide concrete
gutter runs parallel to the unmarked crosswalk and is immediately adjacent to a small concrete
median, which blocks the pedestrian pathway through the driveway. Rebuilding the driveway to
provide sufficient space to mark an 8 -foot crosswalk is recommended and to fully comply with
ADA standards. Pavement legends should also be refreshed at both driveways. Signing and
striping recommendations are depicted on Figure 3.
Turn Restrictions
Reducing the number of conflict points across the Crossing can also improve the pedestrian
experience. Construction of a full or partial median on Amador Valley Boulevard would reduce
the vehicle /pedestrian conflict points at the Crossing by restricting turn movements from the
retail centers across the Crossing. It should be noted that each shopping center associated with
the north and south Retail Driveways has a significant number of additional access points for
motorists, including a signalized full access entrance at the intersection of Amador Valley
Boulevard /Regional Street for the northern center. The southern shopping center has numerous
side - street stop - controlled driveways along Amador Valley Boulevard, Regional Street, and Dublin
Boulevard. Traffic operations under the existing and restricted access conditions were evaluated
based on the analysis methods and procedures outlined in Attachment B.
Existing Conditions
Weekday Mid -day and evening, and Saturday mid -day peak period turning movement counts
were collected at the following locations on a clear day with area schools in normal session:
1. Amador Valley Boulevard /Regional Street
2. Amador Valley Boulevard /Retail Driveways
3. Amador Valley Boulevard /Starward Drive
4. Regional Street /Retail Driveways
These time periods were selected as they experience the highest pedestrian and vehicle volumes,
based on prior data collection efforts. Existing peak hour turning movements and traffic control

devices at the intersections are shown on Figure 4. The analysis results indicate that the
intersections in the study area operate at an acceptable service level, as presented in Table 1.
Full Median
Extending the median on Amador Valley Boulevard across the driveway openings would result in
both driveways restricted to right -in /right -out operation, as shown on Figure 5 and would reduce
the number of vehicle movements over the Crossing from five to three. A median refuge would
allow pedestrians to cross the street in two stages, but would shift traffic in the area. Traffic from
the turning movements that would be affected by a full median was reassigned to the
surrounding street network, as presented on Figure 5. The traffic shifts reflect a conservative
estimate of the number of U -turns at the adjacent signalized intersections. The resulting volumes
were used to evaluate traffic flow under restricted access conditions. As presented in Table 1, the
study intersections are projected to continue operating at acceptable service levels with turn
restrictions at the retail driveways.
Partial UnHiin
As an alternative to a full median, it may be desirable to provide a median break to allow
eastbound left -turns into the northern retail center, as this movement does not travel through the
Crossing. This concept, as depicted on Figure 6, would also provide a median refuge. Potential
traffic shifts that could occur under this scenario are also presented on Figure 6. As presented in
Table 1, the intersections and driveways would continue to operate at an acceptable service level
with a partial median on Amador Valley Boulevard.
RECOMMENDATIONS AND CONCLUSIONS
Based on our analysis of the mid -block crossing on Amador Valley Boulevard between Regional
Street and Starward Drive, we recommend the following improvements for installation in the
near -term:
• Install advanced pedestrian crossing sign assembly with advanced warning beacon
approximately 190 feet west of the Crosswalk
• Install an advance yield markers for westbound and eastbound traffic 30 feet in advance
• Reconstruct southern commercial driveway to meet ADA standards and provide space for
a high - visibility crosswalk
• Install advance stop bars at the commercial driveways and new stop signs
• Install a pedestrian actuated RRFB system and coordinate it with the advanced beacon in
the eastbound direction
• Replace existing outdated /faded signage on Amador Valley Boulevard
• Reduce conflicts at the Crossing by extending the median (either fully or partially) and
restricting turning movements, as presented conceptually on Figures 5 and 6
This completes our Crossing assessment. Please call Kathrin if you have any questions.

ATTACHMENT B: INTERSECTION LEVEL OF SERVICE ANALYSIS METHODS
qualitative description of traffic flow based on factors such as speed, travel time, delay, and
freedom to maneuver. Six levels of service are defined ranging from LOS A (i.e., best operating
conditions) to LOS F (worst operating conditions).
When volumes exceed capacity, stop- and -go conditions result and operations are designated as
LOS F. The City of Dublin strives to maintain LOS D in the study area. Table B -1 summarizes the
relationship between average delay per vehicle and LOS for signalized intersections and Table B -2
summarizes the relationship between delay and LOS for unsignalized intersections. This analysis
was conducted using Synchro 6.0.
Signalized Intersections
Traffic conditions at signalized intersections were evaluated using the method from Chapter 16 of
. This operations analysis
method uses various intersection characteristics (such as traffic volumes, lane geometry, and
signal phasing) to estimate the average control delay experienced by motorists traveling through
an intersection. Control delay incorporates delay associated with deceleration, acceleration,
stopping, and moving up in the queue. Table B -1 summarizes the relationship between average
delay per vehicle and LOS for signalized intersections.
Unsignalized Intersections
Traffic conditions at unsignalized intersections were evaluated using the method from Chapter 17
of the 2000 . With this method, operations are defined by the average
control delay per vehicle (measured in seconds) for each movement that must yield the right -of-
way. For all -way stop - controlled intersections, the average control delay is calculated for the
intersection as a whole. This incorporates delay associated with deceleration, acceleration,
stopping and moving up in the queue. At two -way or side street - controlled intersections, the
control delay (and LOS) is calculated for each controlled movement, the left -turn movement from
the major street, and the entire intersection. For controlled approaches composed of a single
lane, the control delay is computed as the average of all movements in that lane. The delays for
the entire intersection and for the movement or approach with the highest delay are reported.
Table B -2 summarizes the relationship between delay and LOS for unsignalized intersections.

City of Dublin Public Notice
Proposed Partial Median Closure
Between Regional Street and Starward Drive
on Amador Valley Boulevard
The City of Dublin is writing to inform you of the proposed action to restrict
traffic from crossing Amador Valley Boulevard between Regional Street and
Starward Drive from the commercial driveways (Dublin Plaza Center and
Shamrock Village) as shown in the attached location map. The proposed
action will also restrict traffic from making left turns into the southerly
commercial driveway (Dublin Plaza Center) from Amador Valley Boulevard
while travelling towards San Ramon Road.
This action is recommended to address community concerns on pedestrian
safety at the existing white crosswalk connecting the two commercial
driveways. The proposed project will construct a raised concrete median by
extending the existing concrete median, install pedestrian flashing beacons
(Rectangular Rapid Fire Beacons), and new signing and striping.
This item will be reviewed by the City Council at its meeting on Tuesday,
March 19, 2013. If you would like to submit comments to be included in the
staff report for the City Council's consideration, please do so by Tuesday,
March 5, 2013. Otherwise, comments may be received up to the date of the
