SUBJECT: APPROVAL OF A CONTRACT WITH RICK ENGINEERING FOR TRAFFIC
ENGINEERING SERVICES IN CONNECTION WITH SOUTH BROAD
STREET CORRIDOR PLANNING PROGRAM (GPI 149-06).
CAO RECOMMENDATION:
1. Approve a contract with Rick Engineering for traffic engineering services in connection
with South Broad Street.
2. Authorize the CAO to execute a contract for traffic engineering services for a total price
not to exceed$41,800..
DISCUSSION
Background
In July 2006, Council authorized participation in a Caltrans grant program that awarded the City
$110,000 to prepare a draft plan for the South Broad Street Corridor. As required by the grant,
the City allocated$22,000 in matching funds. The grant's overarching purposes were to improve
the area's traffic safety and appearance, encourage mixed land uses, increase affordable housing
and enhance the area's appearance as a major gateway. The City awarded a contract to Rick
Engineering Company to provide consultant services in land use planning, preliminary traffic
analysis, economic development and urban design services leading to the preparation of a draft
plan to begin the public review process.
On February 20, 2007, the City Council authorized $75,000 additional General Fund monies to
cover contract costs. At that time, it appeared the City would be unable to fully expend grant
funds before the grant expired. However, the grant deadline was extended and Rick Engineering
completed its original contract in May 2007 on time and within budget. The grant funds were
fully expended and the $75,000 was not needed.
Since its submittal, the Draft Corridor Plan has been reviewed at 15 public meetings, including
three Planning Commission hearings and a public workshop conducted by the Planning
Commission on October 17`s. The preliminary traffic analysis was based on existing, local traffic
information provided by Caltrans and the City. To keep project costs within the grant funding
available, no new traffic counts or regional traffic analysis were included.
Rick Engineering completed a preliminary traffic study as part of the Draft Corridor Plan. Based
on the results from that study, Caltrans, the Planning Commission and staff have identified the
City Council Staff Report,Tra._.c Engineering Services for the South Brom.-.,treet Corridor Plan
Page 2
need for additional, more detailed traffic studies to evaluate key components of the Draft Plan's
proposed circulation layout and design. Caltrans' initial comments on the Draft Corridor Plan
are mainly on transportation issues related to Broad Street/State Highway 227. As described in
Attachment 2, Caltrans requires more detailed traffic analysis before it can fully evaluate and
consider approving some of the Draft Plan's key traffic and circulation features, such as
landscaped medians, traffic signals, crosswalks, and cul-de-sac streets in the State right-of-way.
The additional work would include traffic counts, traffic projection modeling, intersection
turning movements, level of service analyses, and bicycle/pedestrian safety evaluations. These
technical evaluations are needed to meet Caltrans' requirements, and are also needed to evaluate
circulation and traffic effects as part of the Draft Plan's environmental study.
What's Proposed
The proposed consultant services would provide more detailed, comprehensive information than
was possible under Rick Engineering's original contract workscope, including traffic counts at 21
intersections, detailed intersection analysis for average daily traffic, peak hour and level of
service, and an evaluation of the Plan's design features and potential effects on local and regional
traffic levels (including approved and foreseeable development) over 15- and 30-year planning
horizons. Proposed traffic studies will be based on land use and development projections
provided by Rick Engineering, as modified pursuant to Planning Commission direction. The
consultant will recommend mitigation measures to address the Plan's potential traffic effects,
including pedestrian and bicycle connections and safety, and present the study at two public
meetings.
With completion of the expanded traffic analysis, staff will have sufficient traffic and circulation
analysis for environmental review, and Caltrans will have the information it needs to consider
approval and/or design exceptions to enable the Plan's implementation. For example, the Draft
Plan includes signalized crosswalks at Broad/Woodbridge and Broad/Lawrence, which are
strongly supported by the Planning Commission, the South Broad Street Focus Group and the
public. Detailed traffic analysis is necessary to determine whether signals at these locations
would meet Caltrans traffic warrants and may be approved at these locations.
Rick Engineering prepared a proposal for expanded traffic engineering services, as shown in
Attachment 1, based on recent discussions with the Caltrans and City Public Works staff. The
consultant's proposed fee for the expanded traffic engineering services is $39,800. Staff has
included an additional $2,000 in the funding request as a contingency. Council approval of the
contract is required because the cost of the proposed consultant services exceeds $25,000, the
maximum contract price that can be awarded by the CAO.
FISCAL IMPACT
Rick Engineering's services would be paid through existing consultant service funds in
Community Development Department's approved budget. The contract will be administered by
the Community Development Department, working closely with Public Works and Caltrans staff.
Staff recommends approval of Rick Engineering's proposal as it continues and builds upon the
Draft South Broad Street Corridor Plan and meets the City's needs. The consultant's previous
City Council Staff Report,Tra .,c Engineering Services for the South Broau-street Corridor Plan
Page 3
work and familiarity with the planning area allows start-up immediately upon contract approval,
without the delays that would be expected with a new consultant.
CONCURRENCES
Public Works staff has reviewed this proposal and support approval of a contract with Rick
Engineering as proposed.
ALTERNATIVES
1. Do not fund expanded traffic studies for the South Broad Street Corridor. Expanded traffic
studies will allow the City to address circulation issues raised by the Planning Commission,
citizens, and Caltrans as part of the area plan and environmental review. Land use and
circulation are integral to developing a workable plan for the corridor. Staff does not
recommend this alternative because without the proposed studies, it will not be possible to
fully evaluate and respond to these comments.

SOUTH BROAD STREET CORRIDOR PLAN=SYNCHRO TRAFFIC MODEL.REVIEW
Dear Mr. Hook:
We have reviewed the City of San Luis Obispo's recent Synchro/SimTraffic model regarding the
South Broad Street Corridor. We appreciate the opportunity to provide technical assistance to
your city's important community planning effort.
Overall, the Synchro model is a good initial start for the comprehensive traffic analysis. We also
support the extended project limits on Broad Street from South Street to Tank Farm Road, which
is adequate coverage of the entire study area.
Regarding the existing model, Caltrans' reviewed only the am. peak travel hours as the
preliminary study needs more information before further review can be conducted. Additional
traffic engineering services are needed to provide the details necessary for Caltrans to evaluate
several key transportation features of the plan such as signalized crosswalks and proposed cul-
de-sac streets along Broad Street. The study must also address regional traffic circulation and
consider both local and regional traffic models.
One major concern is that the existing model used Traffrx software to analyze the intersection
performance. Traffix is mostly a macroscopic level of service estimator for intersection
operations. As such, it cannot emulate loop detection for either vehicles or pedestrians, and it
does not trace each individual vehicle in the network. This means it does not provide detailed
performance measures such as total system delay, total Vehicle Miles Traveled (VMT), Vehicle
Hours Traveled (VHT), 95 percentile queue analysis', queue starvation, arterial speed
performance and more.
The major need and purpose of the corridor plan is to provide a safe and pedestrian-friendly
facility. As such, the analysis should include pedestrian counts at all signal locations and critical
intersections where pedestrian crossing is expected. Toward that goal, the city should conduct a
full operational analysis using the Synchro/Sim Traffic macro/micro-simulation model. We also
recommend calibrating the existing model before adding any future analyses.
95 percentile queue analysis determines the location where the traffic queues 95 percent of the time.
Queue starvation occurs when a downstream traffic signal is green,but it camiat=vice at fids opacity efficiency because the
upstream signal is red.

Micro-simulation software has the capability to analyze the following:
• Signal coordination along the corridor in a future-year analysis
• Median effect on the arterial performance
• Pedestrian effect on the signalized intersection(s)
• 95 percentile queue and the potential for queue starvation
• Scenarios and alternative runs
Queues in the micro-simulation model are typically higher than the macro-simulation due to
conditions that are not reflected in a macroscopic model. These conditions include traffic
spillback between intersections and beyond turning bays, forced lane changes, unbalanced lane
use for downstream turns, and other subtle traffic flow interactions.
Micro-simulation also allows existing and predicted traffic conditions to be simulated in a 2D or
3D model for public meeting presentations. However, micro-simulation does require more time,
as much as three or four times more than macro-simulation, depending on the analyst's
proficiency in using the model.
We also offer the following comments for your consideration regarding the existing model:
1) The model's link lengths were not to scale and, thus, do not depict the existing lane distance
and intersection locations. This will become a critical element during the 95'h percentile
queue analysis.
2) The model link's speed was set to the default 30 mph. The model needs to reflect the actual
free flow speed along the South Broad Street Corridor.
3) It appears the truck percentage was set at the Synchro default of two percent. Is that the
correct percentage? Caltrans 2005 truck percentage data shows Orc utt Road at an estimated
4.8 percent for total trucks. As such,the trick volume needs verification.
4) The ffighway 227 Broad Street/Orcutt Road intersection lane configuration does not depict
existing conditions.
5) The Highway 227 Broad Street/Capitolio Way intersection should be included in the model.
6) The Highway 227 Broad Street/Industrial Way signal should be included in the model.
7) The model erroneously shows Broad Street as an eight-lane facility from Orcutt Road to
Tank Farm Road.
8) The model should indicate the peak travel hour and relevant timeframe.
9) The model's signal timing plans do not reflect existing conditions. Signal timing plans can
be obtained through the California Public Records Act (CPRA) from District Signal
Operations. For this information, please contact Donna Carter at 805-549-3318 or
