(3) 90% signal/signing/striping design plans and cost estimates, (4) preparation of specifications & special provisions, (5) 100% PS&E delivery with construction plans, and
(6) bid/advertisement services if required by the lead agency.
General provisions & technical specifications are prepared with the agency’s boilerplate specifications. All final plans & specs, signed and sealed by our California Registered Civil engineers, will conform to local (City /County/APWA Greenbook) and/or state (Caltrans) guidelines and plan preparation manuals. Final signed/sealed plans are submitted on 24”X36”, 4- millimeter Mylar sheets, or on vellum medium if requested by the agency.
Our signing and striping plans are prepared in accordance with the latest California Manual on Uniform Traffic Control Devices (CA -MUTCD 2014) and Caltrans Standard Plans (2018). All proposed signage and pavement markings items are identified on our plans both by construction note and MUTCD code.
Traffic Signal Timing/Synchronization/Coordination Traffic signal timing and coordination of signalized intersections and arterial corridors is the staple of our firm’s expertise. We utilize SYNCHRO® 11.0 and SimTraffic© 11.0 micro- computer simulation modules to build traffic signal network models, analyze intersections/systems, conduct and fine-tune simulations, and develop optimized traffic signal timing plans to deploy in the field. Minagar & Associates, Inc. is a leading national authority on the application, utilization, and training of Synchro software, training 88 cities and all Southern California districts for the past 10 years. Our traffic modeling services include preparing a baseline model of the existing signal network based on existing field and office data collection, developing a set of optimized proposed peak hour timing plans, modifying the timing and coordination plans based on lead-agency comments, and conducting final fine -tuning efforts based on on-site/field implementations, as well as:
- Review of existing conditions, such as roadway geometries, striping and lane configurations, traffic signal control information, as well as inventories and inspections; 1 Request for Proposals to Provide

- Review of deficiencies , such as parking prohibitions, excessive pedestrian/bicyclist traffic, sources of congestion, and/or unusual traffic generating conditions; - Development of an effective highway model, and
- Development of operational SimTraffic micro-models.
Minagar is experienced in using Synchro to analyze the operating conditions of various intersection types, including queuing, delay per vehicle, average speed, and vehicles denied entry. If, based on the traffic study, queue lengths increase when compared to the existing design, a recommendation regarding signal timing will also be included in the traffic study report.
Implementation of our optimized/synchronized timing includes:
- Revising/Optimizing Traffic Signal Timings : We have consistently provided successful signal timing strategies to numerous agencies and projects, particularly in the areas:
• Cycle Lengths and Offsets;
• Left-turn phasing rotations, protected left-turn phase re-service; • Timing Parameters to include full accommodation for pedestrian traffic within splits; and • Time-of-day start and stop intervals as recommended for the various timing plans. - Inputting Revised/Optimized Traffic Signal Timings: Our field and traffic signal timing staff can provide installation of new signal timings, including:
• Full traffic engineering implementation services, or as technical support to local agencies; • Utilization of existing interconnect systems during implementation; and • Development of time-based signal coordination techniques.
Signal Timing Improvement Strategies for the intersection/ arterial/signal network will be provided to the lead agency in addition to our synchronization/coordination efforts, such as:
• Providing technical support to the agency’s traffic signal maintenance staff • Interfacing with adjacent jurisdictions for jointly owned or operated signals
The Minagar & Associates, Inc. Team also provides evaluations of currently used time-referencing equipment for all traffic signal controllers along a given corridor to determine the recommended type of time clocks (e.g., GPS clocks, WWV, etc.) to be utiliz ed for accurately coordinated time- referencing, especially across jurisdiction boundaries.
We are also experienced in providing procurement recommendations for new/updated traffic signal controller units and/or assemblies, prior to the implementation of signal timings. This includes on-site assistance for turn-on activity of new equipment, as well as “fine-tuning” of traffic signal timings/settings and thorough logs and records of all changes carried out prior to the implementation to the satisfaction of the lead agency.

- Trip Generation: Estimation of vehicular trips to be generated from the proposed project; - Trip Distribution: Includes developing a model to determine the projected paths of future trips; - Trip Assignment: Identification of the magnitude and direction of project vehicular trips; - Traffic Scenarios: Involves developing particular “target years” and “conditions” to analyze with respect to important milestones in both the construction phasing of the project and future conditions of the County, such as the choice of target years or application of any trip credits; - Environmental Clearance and Traffic Congestion Mitigation: Includes determining a project's traffic impacts and developing solutions reduce this through mitigation measures . Consultation with lead agency staff and Caltrans (if under state right-of-way) shall also be pursued as needed, so that reviews may be expedited and conflicts and/or misunderstandings are reduced in both the local agency review process as well as any Caltrans encroachment permit processes.
Parking Studies Local municipalities generally have parking codes by which new or modified development must abide. Beyond the “black and white” parking code, however, a number of issues can arise which require studying a given site’s current parking situation, and forecasting its future parking conditions. Our typical parking study approach takes this into account and consists of the following steps:
1. Conduct on-site baseline parking accumulation surveys during peak periods of development to determine the magnitude and patterns of existing parking activity. The time frame(s) for these surveys will be verified with the lead agency at the start of each parking study project.
2. Determine peak hour and day at the site from the parking surveys.
3. Estimate projected parking demand of the proposed development based on the Institute of Transportation Engineers’ (ITE) and/or Urban Land Institute’s (ULI) parking methodologies.
4. Compare local agency parking requirements with existing and forecasted parking demand, then determine if the site will provide an adequate parking supply under fully built-out conditions.
5. Provide recommendations and/or strategies to improve on- and/or off-site parking conditions.
Mitigation Planning & Impact Fee Analysis
- Recommendation of Mitigation Measures: Customized mitigation measures techniques shall be recommended if the subject project exceeds acceptable impact thresholds. - Preparation of Mitigation Plans: This may include plans, schematics, or diagrams such as Signal Modification Plans (1:20 scale), Signing & Striping Plans (1:40 scale), or Parking Layouts. - Impact Fees : As required by the Agency, we will also conduct an impact fee analysis to determine the fair -share contribution of traffic improvements to be apportioned to a given developer. Because the methodology for determining impact fees can vary by city, county, etc., our staff will meet with the lead agency on the approved method for calculating impact fees.

Our most common systems evaluations consist of performing “Before/After” studies, which measure improvements ( travel time, mobility, fuel consumption, etc.) resulting from project implementation.
“Before/After” Studies and Reports We usually perform two performance evaluation studies: (1) a field "floating car survey" study of field-collected traffic data, and (2) a comparison of computer -generated traffic simulation models (Synchro/SimTraffic 11.0). Both are used to identify improvements in the "before" & "after" Measures of Effectiveness (MOEs).
Performance Evaluation of Regional Surface Transportation Improvements Projects (RSTI) We also provide RSTI evaluation services, which involve quantifying and evaluating the benefits and impacts of a given completed surface improvement project on the surrounding transportation network. These include studies such as:
- Signal Analyses, which measure the improved signal(s) operation & performance and may use field data such as turning movement counts (TMCs), cycle lengths, signal phasings, etc., - Arterial Analyses, which measure improved traffic flow along a given arterial, and - Unsignalized Intersection Analyses.
