2.0 SCOPE OF WORK APPROACH
STC’s general and technical approach, and project controls will clearly illustrate our ability to accomplish the work. Our proposed approach is detailed below.
2.1 Management Approach
Traffic operations and systems projects are unique and merit a unique approach. This section briefly describes STC’s management approach and project controls to assist staff with adhering to scope, schedule, and budget.
Project Initiation: Once City staff alerts STC of a potential task order, STC’s project manager Mr. Duncan Hughes will conduct an in-person or over the phone meeting with the key point of contact the City. If necessary, Duncan will meet City staff in the field to review the item on site. This meeting is designed to aid the City in clearly conveying the concerns and issues that should be addressed in the pending task order.
STC Traffic, Inc. – City of Lake Elsinore | On-Call Traffic Operations Services 4 Prepare Scope of Work and Fee Proposal: Duncan Hughes will prepare a detailed scope of work and fee proposal for requested tasks. Duncan will work directly with the City’s project manager and other agencies, consultants, and contractors to refine the scope of work.
STC realizes that City resources are limited. The purpose of the scoping process is to develop a scope and fee that meets the intent of the project in the most cost-effective manner possible. It will be Duncan’s responsibility to track the hours committed to the task and ensure that the established budget is not exceeded.
Contracting: Duncan Hughes will work with the City’s contracting department to acquire the appropriate signatures and contract documents for each task. The City’s standard contract documents will be used for tasks.
Project Kick-Off, Coordination, And Schedule: Regular
communication between Duncan Hughes and the key point of contact at the City will be critical to maintaining the project schedule and to the overall success of the project. Throughout the duration of the contract, Duncan will schedule regular check in meetings with City staff to review all outstanding tasks. Duncan will submit a baseline schedule at the start of the project that will serve as the basis for monitoring and controlling project activities to help decide how to use resources to achieve time and cost goals. The baseline schedule will be reviewed and approved by City staff. The schedule will be developed through Microsoft Project. Duncan will update the schedule through the completion of the task and will furnish a monthly project schedule update to the City with sufficient detail to show the actual versus scheduled progress on tasks and subtasks.
Technical Analysis and Design: Tasks assigned to STC will be completed by staff who are familiar with the City’s policies and the applicable standards and guidelines. Through our practice we have developed signal timing guidelines and standard operating procedures that our staff adhere to on all timing projects. As applicable, the guidelines include nuance associated with agency preference. STC will provide professional opinions, recommendations, reports and/or plans for traffic related issues and improvements.
Quality Assurance and Quality Control (QA/QC): Work products delivered to the City will be reviewed by engineers and project managers not directly involved in production or review of the project. Time to review all work products will be built into the project schedule and will be clearly documented and maintained by STC during the project. In addition to formal reviews of work products, Duncan will conduct over the shoulder reviews throughout the life of the task order. This hands-on project management style provides assurance to the City that the work products in process are on-task and are in line with the scope of work and pending deadlines. Plans prepared by STC are reviewed by our in- house Construction Management team for constructability and errors.

2.2.3 Traffic Signal Timing and Coordination Optimization Review of Existing Conditions: STC will review the existing traffic conditions based on the existing geometry, traffic volumes and signal timing. Traffic volumes will be collected, or recent traffic volumes will be requested from the City. Existing roadway geometry, phase type and signal timing data will be verified in the field. Data such as number and type of approach lanes, turn pocket length, crosswalk distance, posted speed and lane add/drops will be collected. Traffic volume data will be collected for peak periods on a typical weekday and if necessary, for weekend. Observations will be made in field for any queuing and other operation issues. Signal timing will be uploaded from the controller in the field.
Traffic analysis model will be developed using the latest version of Synchro and based on the existing data. Traffic model for each peak hour will be developed and calibrated to reflect the existing conditions.
Traffic Signal Timing Calculations: STC will follow the City’s general timing guidelines to calculate the base signal timing parameters. The calculations will be based on field data and measurements and CA- MUTCD standards. STC will organize the field measurements and base signal timing calculations in a tabular format. Some of the base signal timing parameter that will be calculated are as follows:
Minimum Green Time, Yellow Change Clearance, Red Clearance, Walk Interval, and Pedestrian Clearance Interval.
Traffic Signal Optimization: STC will use the calibrated existing conditions Synchro model with updated base signal timing parameter to optimize the signal timing. Signal timings for corridors currently operating on coordination plan or proposed to be coordinated will be optimized to develop coordination plans. The traffic counts, field review data, and model will be utilized to determine the optimal signal groupings, cycle lengths, splits, and offsets. STC will develop time of day plans for all the peak period and the existing traffic counts will be analyzed to determine the time of day schedule for the new coordination plans.
Traffic Signal Timing Sheets: STC will prepare traffic signal timing sheets compatible with the existing controller program at each respective intersection.
STC understands that the City has a variety of traffic signal controllers in the City with various software programs including: Econolite ASC2, 200, 233, 2033 and McCain Omni software. STC excels at traffic signal timing and can develop timing plans for any of the above-mentioned controller programs. The timing sheets will incorporate the updated basic timing parameters and coordinated time-of-day plans.
Testing, Field Implementation and Fine Tuning: STC has extensive experience in the traffic signal controllers such as Econolite, Type 170 and 2070 and has each of the controllers in house. The proposed signal timing will be bench tested in house prior to implementing in the field. The finalized signal timing plans will then be inputted in the traffic controller at each individual intersection. STC will observe the coordination plans in the field to ensure operations are performing as intended. Adjustments to the signal timing will be made as required to improve the signal operation. Any changes made in the field will be noted. Once timing changes have been made and all comments addressed, STC will provide final timing sheets to the City. STC will update the Synchro model with the final timing plans.

MENIFEE ON-CALL TRAFFIC ENGINEERING AND SUPPORT SERVICES STC has held the On-Call Traffic Engineering and Support contract with the City of Menifee since 2014.
The City utilizes STC to augment staff in the Traffic Engineering Division. As extension of staff STC is responsible for completing day-to-day City traffic engineering tasks, including responding to service calls, responsible for inventorying and inspecting all existing traffic signal components. STC researched existing traffic signal as-builts and conducted extensive field investigations to obtain a complete inventory of the traffic signal equipment. The design work includes installation of radios, 2070 controllers, CCTV, UPS, switches, routers, and related communication system elements. With the design plans, specifications, and cost estimates for the project approved by the City, STC prepared all Caltrans E-76 forms for authorization to proceed in accordance with the Local Assistance Procedures Manual. STC will provide construction engineering, integration, and project close-out services. As part of construction engineering, STC will develop and implement new timing sheets due to the new upgraded controllers.
The existing 170E controllers are being upgraded to a 2070 ATC controller with Omni software.
During design of the project, STC developed a concept to install a Type 15 street light pole with sectoral antennas at two different high points within the City to provide a more secure and reliable wireless communication design. These high points were on Eastern Water Municipal District (EMWD) property. STC led the design and coordination efforts to get poles installed on EMWD property as a separate task order to avoid the complex Caltrans E- 76 right-of-way processing. STC also coordinated with the County of Riverside to obtain the spare Type 15 poles at no cost to the City, which saved out-of-pocket costs. The purpose of using the high points was to reduce the amount of wireless failure points by avoiding a linear bussed point-to-point system and establishing a hub point-to- multipoint system. This design will save the City on future maintenance and troubleshooting costs.
STC Traffic, Inc. – City of Lake Elsinore | On-Call Traffic Operations Services 12 Newport Road & Scott Road Corridors Signal Operations Projects. The City recently commissioned STC with two projects that involved developing coordination timing for the Newport Road and Scott Road corridors. The overall goal of these projects involved reducing congestion along the corridors and improving traffic operations to increase public safety and improve travel times. The projects included coordination with the I-215 Caltrans on- and off-ramps. This involved extensive coordination efforts with the City of Menifee and Caltrans. Data collection work also required coordination with the City, Caltrans, and a count data subconsultant. Technical work included the development of the Synchro models; determining corridor cycle lengths, splits, offsets, and time-of-day for the coordination plans; and bench-testing, field-implementing, and preparing fine-tune adjustments based on field evaluations of the operations. Additionally, STC provided communications integration and inspection services.
Traffic Signal Design Services. STC provided roadway and signal design improvements at the intersection of Murrieta Road and Scott Road. This project involves developing
traffic signal design plans, signing, and striping plans, specifications, and cost estimates. Additionally, STC is managing a civil engineering subconsultant to produce

In 2016, STC’s HSIP grant development efforts led to the award of $1,208,200 to Temecula for the installation fiber optic communication system upgrades, including approximately two miles of new conduit, over 22,500 linear feet of single mode fiber optic cable, new ATC traffic signal controllers, new CCTV cameras, and other communications-related equipment. The project area includes 41 traffic signals along the Winchester Road, Rancho California Road, and Temecula Parkway corridors. The project will implement new communications and traffic control systems that will modernize the City’s traffic signal system and provide infrastructure to traffic signals not currently connected. These systems will provide consistent, reliable, and modern communications and control for more than one-third of the City’s traffic signal system on the most critical arterials in Temecula. The systems will enable proactive traffic signal management including coordinated and adaptive traffic signal operations and response to real time traffic conditions.
STC Traffic, Inc. – City of Lake Elsinore | On-Call Traffic Operations Services 13 Ynez Road and La Paz Road Intersection & Signal Design and Operations. Development on Temecula Parkway has necessitated a new traffic signal at Ynez Road and La Paz Road in the existing right‐of‐way.
The project also required pavement widening on La Paz road to accommodate the 3 travel lanes. STC was responsible for design of all aspects of the intersection. STC provided engineering plans for the pavement widening, along with preparing design plans for the new traffic signal and signage and striping plans. STC also prepared an engineer’s construction cost estimate. STC was later tasked with providing fiber optic communication design services for the intersection, a pedestrian ramp, and with providing design services during construction of the intersection.
HSIP Cycle 9 Signal Modification Improvements –
Permissive Left-Turn to Protected/Permissive Left-Turn.
Based on a successful grant application, the City
commissioned STC to prepare design plans, specifications, and estimates (PS&E) for implementing protected-left-turn phasing at 5 select intersections in the City. The project supports the Temecula community’s transportation safety goals by reducing the number and severity of intersection traffic accidents between permissive left turners and other motorists, bicyclists, or pedestrians. STC is preparing traffic signal modification plans, installation of new traffic signal poles, mast arms, and controller equipment, and installation of ADA compliant pedestrian access. responding to resident’s calls and requests, plan checking, and attending sheriff meetings. STC staff are present at City Hall twice a week and responsible for coordinating project tasks with various departments including traffic signal maintenance, planning, land development, and construction management. Weekly tasks performed by STC staff include traffic engineering design plans, reviewing and responding to citizen requests, and reviewing development traffic impact studies and design plans.
The increasingly vital role we have in implementing Menifee’s mobility and transportation goals has led to more diverse services provided to the community. We have written several successful HSIP, SSARP, and ATGP grant applications and have executed most of the ensuing projects, including serving as a key subconsultant for the Menifee Active Transportation Plan , preparing the City’s Systemic Safety Analysis Report, and providing traffic signal communications design and operations services for the execution of the HSIP projects . We are in the process of upgrading the City’s traffic signal communications and operations infrastructure to cutting edge technology and funded through grants. The following are brief descriptions of our work on signal communications, operations, and other related work in Menifee.
Menifee HSIP Wireless Interconnect System. STC successfully wrote 2 HSIP Cycle 7 grants for the Eastside and Westside Wireless Interconnect System Projects, securing over $1 million in federal funding for installation of a citywide traffic communication. The goal of the HSIP project is to improve safety and efficiency along Menifee’s streets through traffic signal timing and coordination, equipment upgrades, and monitoring systems. STC was later awarded the design contract for the citywide traffic communication system project through an RFP process. The final design plans provide communication and signal controller upgrades at all 62 signalized intersections throughout the City. The signals communicate via wireless radios back to City Hall and the system will be managed from the traffic management center (TMC)/emergency operation center (EOC), which was also designed by STC. STC is Street Lighting Services. STC is working on a variety of street lighting tasks within the City. The City recently shifted to LS3 for their lighting system, which means the City will own and maintain their street lighting system. Because of this, the City has been working with STC to standardize the new street lighting services for the City. Examples of our street lighting tasks include developing the City’s Safety
STC Traffic, Inc. – City of Lake Elsinore | On-Call Traffic Operations Services 14 and Street Lighting Guideline manual in order to ensure standardization of street lighting within the City; performing all plan check reviews for street lighting design plans submitted to the City; performing electrical inspections on street lighting systems for the City. STC will also train City maintenance staff in electrical inspections and in the maintenance of the newly installed street light systems.
JURUPA VALLEY ON-CALL TRAFFIC OPERATIONS SERVICES
STC serves as a prime for the City’s On-Call Traffic Engineering contract, assisting with traffic operations.
On-Call Operations Services. Our engineers and technicians have developed signal timing plans, coordination timing plans, and communication troubleshooting for the Jurupa Valley community at various locations. STC is conducting preliminary field observations of existing traffic operations and, using Synchro, developing coordination timing plans to implement in the field. STC is also investigating communications issues between signals. We have also coordinated five arterials and retimed or provided new timing for approximately 30 intersections. We have also assisted the City with traffic signal plan reviews and ITS and communication systems planning and design. As part of our work, we have coordinated with adjacent local cities and regional agencies, including the County of Riverside and Caltrans District 8.
Flashing Yellow Signal Timing Operations. STC recently
completed special operation timing plans for flashing yellow protective/ permissive left turns at two signalized intersections in the City. The locations include Pyrite Street/Mission Boulevard and Wineville Avenue/Landon Drive. STC developed the timing plans and then programmed and tested the special left-turn operation in the office prior to field implementation.
During field implementation, STC was fine-tuned the timing plans to ensure the City was comfortable with the specialized flashing yellow operation.
Limonite Coordination Timing Plans. STC developed signal coordination plans for nine signals along Limonite Avenue in the City of Jurupa Valley, from Sumner Avenue to Wineville Avenue. STC uploaded the existing timing plans from the signals in the field and monitored existing conditions to help determine appropriate coordination timing and time-of-day plans. Synchro was used to develop the timing plans during the design phase. After the plans were finalized, STC implemented the new timing plans into the signal controllers and field verified the coordination to ensure intended operation.
6.0 CONCLUSION
STC’s staff have experience executing this exact scope of services and have demonstrated leadership in on-call traffic operation services with neighboring agencies. Our staff is flexible working the hours necessary to make the deadline. We are the “right sized” team to execute this work. The task orders are likely to be in the thousands range. Executing small size contracts on an on-call basis has been our business focus since our inception in 2007. STC will meet the City’s needs in responsive and flexible ways and will get to the task at hand quickly and promote efficiency and performance. STC looks forward to working with Lake Elsinore to bring innovative practice and technology to the streets of the City to solve real issues and make a positive impact for the traveling public.
