SUBJECT: 2017 TRAFFIC SAFETY AND OPERATIONS REPORT
RECOMMENDATION
Receive the 2017 Traffic Safety and Operations Report (Attachment A) and recommended traffic
safety measures.
REPORT-IN-BRIEF
The following report summarizes the Traffic Safety Program and 2017 Annual Traffic Safety
Report which includes recommended safety projects to address high priority collision locations.
Additionally, the report provides a status update to currently funded or completed safety projects
from prior Safety Reports. While not every recommended measure can be feasibly funded given
the financial limitations of the City’s financial resources, this report identifies which project s will
be funded with available budget in approved financial plans and which projects will require
additional fu nding consideration as part of the next financial plan.
DISCUSSION
Background
The Annual Traffic Safety Program (“Program”) began in 2002 to identify high collision
locations within the City and actively pursue mitigation measures at those locations. Now in its
17th year, the program has demonstrated continued effectiveness and lasting outcomes. This
program has had long-term success with a 60% reduction in citywide collisions since the
program began. This reduction has been accomplished despite increasing traffic volumes on City
streets.
New to the program is the reporting of aggregate citywide auto volume trends. Reporting growth
or declines in citywide travel provides a context for increases or reductions in traffic collisions.
Since the General Plan was updated, based on the latest volume data 2014-2016, citywide auto
volumes have increased by approximately 3% (1% each year).

Item 8
Estimated Citywide 10 Year Vehicle Volume Trend
While the City overall experienced approximately 3% growth in auto volumes from 2014 to
2016, different areas of the City experience different changes in traffic volumes as shown in the
table below. These changes are estimated based on an aggregate of traffic volume counts taken at
key counting stations throughout the City.
Geographic Area 2014 (LUCE) – 2016 Auto Volume Changes
Citywide +3%
Margarita Area +18%
S. Broad / Orcutt Area +13%
Chorro/Santa Rosa/California Area +5%
Old Town Area +4%
Mid Broad / Johnson Area +3%
LOVR / Madonna Area +3%
Downtown Area 0%
Foothill Area -6%
Airport Area -8%
Upper Monterey -11%
In 2017, the total number of collisions increased by 4% (up 21 collisions) from the previous year .
That represents, however, the second lowest number of collisions since the program began. Total
injur y collisions increased 3% (up 5 collisions) in 2017. There was one traffic -related fatality on
City r ight of way in 2017. A bicyclist was rear-ended by a driver on Foothill Boulevard near
Ferrini. The driver was subsequently charged with driving under the influence and manslaughter.
Since inception of the program, total annual injury collisions are down 35% (down 107
collisions).
The number of pedestrian collisions increased by four in 2017. That amount is still in line with a
relatively static trend since 2008. In 2017, the number of bicycle collisions was the lowest
recorded (39 collisions)–a 22% decline from the previous year and a 47% decline from peak
levels in 2009 (73 collision). That information is summarized in the chart below.

2017 Traffic Safety and Operations Report Overview
The Traffic Safety and Operations Report (TSR) reviews all intersections and street segments in
the City for calendar year 2017 and identifies patterns and collisions rates. This information
enables staff to prioritize work efforts and inform policy makers and the community. Based on
these patterns, recommendations are made for the highest collision locations of each intersection
and street segment by classification. Staff develops specific actions and improvements at each
location, or, recommends continued monitoring if no prevalent pattern can be identified.
It typically takes up to six mo nths after the end of the year for all collision reports to be reported,
received, and analyzed. Often late collision reports are filed by private parties and extended
investigation periods are needed before collision reports are finalized.
The TSR identifies patterns for the highest -rate collision locations of similar street classifications
and then are separated for the following transportation modes: Automobiles, Bicycles, and
Pedestrians. These locations are narrowed down, and the top five locations are analyzed to
identify possible mitigation strategies to address safety issues. For example, all arterial segments
are compared to each other to establish the highest rate locations and thereby establish the
priority order for mitigation or safety improvements. In order to determine if corrective measures
could reduce the likelihood of a collision type identified in the pattern, a comprehensive review
of each location is conducted. This review includes a survey of the field conditions and travel
behavior.
In addition to the high-collision locations identified, the 2017 TSR included an additional
comprehensive and proactive analysis of bicycle and pedestrian collisions—looking for patterns
and trends systematically, in addition to looking at each specific lo cation for patterns.
Table 1 below summarizes the high-ranking locations identified in the 2017 TSR where new
recommended safety improvement project s were identified for mitigation.

The TSR program typically receives recurring annual funding to implement identified projects ,
this funding is made possible thru the local revenue measure and SB 1 funding. Table 3 identifies
the new safety projects can be reasonably funded under the current funding levels. Many projects
however exceed the level funding allocated annually, additional funding for these projects are
typically requested as part of the following Capital Improveme nt Program.

Policy Context
The Traffic Safety Program and Report are consistent with the General Plan, Specific Plans,
Bicycle Transportation Plan, City’s endorsement of the NACTO bicycle design guidance, and
the City’s 2016 adopted Vision Zero Policy (Attachment B) to eliminate traffic-related fatalities
and serious injuries by 2030.
Public Engagement
Many minor, operational, and non-controversial projects identified in the Traffic Safety Report
would not otherwise be presented to Council if not part of the Traffic Safety Report. The Council
has delegated authority to carry out these types of projects to the Public Works Director or their
designee through the City’s Municipal Code. For these types of project s public engagement will
be limited to this Council meeting.
Larger, more complex, and potentially controversial projects will include public engagement per
the City’s Public Engagement Manual as they move forward. There is flexibility within the broad
description of the recommended mitigations specifically to allow for refinement from public
engagement and feedback.
CONCURRENCE
Packet Pg. 106
Item 8
The Police Department has reviewed the 2017 TSR and concurs with its findings.
ENVIRONMENTAL REVIEW
The California Environmental Quality Act does not apply to the recommended action in this
report, because the action does not constitute a “Project” under CEQA Guidelines Sec. 15278.
Even if the TSR is a project, it would be categorically exempt from environmental review per
CEQA Guidelines 15306 (Information Collection). Individual projects may require varying
degrees of environmental review that will be determined as they move forward.

Staff is recommending that new projects listed in Table 3 above be funded t hrough the City’s
annual Traffic Safety Program allocation, which has a current balance of $41,983. The 2017 -19
Financial Plan allocates $30,000 annually for the Traffic Safety Program funded through the
Local Revenue Measure. With the current balance and anticipated $30,000 allocated in fiscal
year 2019-20, total available funding for implementation of the 2017 Traffic Safety and
Operations Report is $73,983. The total cost of the feasible projects as identified in Table 3 is
estimated at approximately $67,000. Remaining balance after project completions will be used to
fund other minor projects as they are identified through 2019 as part of the future 2018 TSR.
In addition, as identified above, there are six other safety projects estimated at $456,000 in
addition to approximately $2,300,000 for the California & Taft roundabout which cannot be
funded through the current allocation of traffic safety report funding. The California & Taft
roundabout is now included in the Citywide Transportation Impact Fee program, however
insufficient fees have yet been collected to implement this project. Staff will continue pursuing
grant funding opportunities and return to Council with a proposed funding strategy for these
projects as part of the 2019-21 Financial Plan. The Traffic Safety Program would not be possible
without Local Revenue Measure and SB1 funding. In 2011 the program was effectively
suspended due to lack of funding
Packet Pg. 107
Item 8
ALTERNATIVE
The Council may choose not to conceptually approve one or more of the measures identified.
Staff does not recommend this as these locations are currently experiencing high collision rates
with injuries and property damages, if measures are not taken these collision patterns may
continue.
