Memorandum
Date: January 29, 2026
To: Farid Javandel, City of Napa
From: Saran Chan and Ron Ramos, Fehr š Peers
Subject: Lincoln Avenue Project Morning Peak Hour
WC25-4233
As part of the Lincoln Avenue Traffic Safety and Paving Project (Project) the City of Napa is proposing traffic safety improvements along Lincoln Avenue between California Boulevard and the Silverado Trail (Phase 1: California Avenue to Soscol Avenue and Phase 2: Soscol Avenue to the Silverado Trail). The project includes sidewalk rehabilitation, buffered bike lanes, improved crosswalks, and lane reductions throughout the corridor. Fehr š Peers prepared before-and-after morning peak hour traffic simulation videos for the Phase 1 of the Lincoln Avenue, which includes the segments between California Boulevard and Soscol Avenue. The morning peak hour was selected as it has the highest traffic volumes. The purpose of the simulation videos is to illustrate the before-and- after traffic conditions of the corridor. Four videos were prepared that illustrate morning traffic conditions at the following locations:
Lincoln Avenue/California Boulevard
Lincoln Avenue/Kennedy Way
Lincoln Avenue/Jefferson Street
Lincoln Avenue/Soscol Avenue
Video locations were determined in coordination with City of Napa staff and include existing and proposed conditions. This technical memorandum summarizes the methodology and analysis approach to preparing the video simulation. Travel time, Level of Service (LOS), and delay calculations are also included for informational purposes.
Summary of Findings
The analysis indicates that, following implementation of the Project, corridor morning peak hour traffic operations continue to operate under capacity and the study intersections continue to operate at LOS D or better. The results are consistent with the Synchro results provided by the City of Napa staff.
Based on the analysis results and microsimulation observations, the Project does not result in queuing spilling over between intersections or gridlock conditions.
Study Area
The study area includes Lincoln Avenue from California Boulevard to Soscol Avenue. The following seven intersections are included in the analysis:
1. Lincoln Avenue/California Boulevard
2. Lincoln Avenue/Marin Street
3. Lincoln Avenue/Kennedy Way
4. Lincoln Avenue/Jefferson Street
5. Lincoln Avenue/Main Street
6. Lincoln Avenue/Yajome Street
7. Lincoln Avenue/Soscol Avenue
Data Collection
City of Napa Staff provided morning peak hour traffic counts for all the study intersections with the exceptions of Lincoln Avenue/Yajome Street intersection. For this intersection, Fehr š Peers estimated traffic volumes using StreetLight Data. In addition, City of Napa staff provided Synchro models, including signal timing data, for all signalized intersections within the study area.
Field Work
Fehr š Peers conducted field observations under typical weather conditions while school was in session December 10, 2026. Lane striping along the corridor was confirmed, and signal timings observed in the field were consistent with the timings provided by City of Napa staff.
Overall, the Lincoln Avenue corridor was observed to be operating under capacity, with queues generally clearing within each signal cycle.
Traffic Conditions
Based on existing lane configurations, peak hour traffic volumes, and observed pedestrian and bicycle activity, traffic operations along Lincoln Avenue were evaluated using the SimTraffic 12.0 microsimulation model.
Lincoln Avenue Travel Times
Morning peak hour travel times along Lincoln Avenue, between California Boulevard and Soscol Avenue in both directions, are summarized in Table 1. Detailed travel time worksheets can be found in Attachment A.

As show in Table 1, implementation of the Lincoln Avenue Project results in an increase in travel times of approximately 30 seconds or less in both directions. Consistent with microsimulation observations, the project does not result in in queuing spilling over between intersections or gridlock conditions, and the corridor continues to operate under capacity.
Intersection Level of Service
Average intersection delay and LOS1 results for the morning peak hour are summarized in Table 2.
Detailed LOS worksheets can be found in Attachment A.

Notes: Bold text indicates potentially unacceptable intersection operations.
1. SSSC = side-street stop-control
2. Average intersection delay is calculated using SimTraffic simulations, and LOS thresholds are determined based on the HCM 7th Edition.
3. Results are presented as Intersection Delay (Worst Movement Delay).
Source: Fehr š Peers, 2025
As shown in Table 2, all study intersections operate at LOS D or better under both Existing and Project conditions. While minor increases in delay are observed at some intersections under Project conditions, overall operations remain under capacity. At the Lincoln Avenue/ Marin Street and Lincoln Avenue/ Kennedy Way intersections, the worst-movement delay increases to LOS E, which is considered at-capacity operation. If delays increase further and approach LOS F in the future, additional analysis may be warranted to identify potential treatments to address the congestion.
Conclusion
Based on the results of this analysis, the Lincoln Avenue Project is expected to operate similar to existing conditions during the morning peak hour as the corridor and study intersections continue to operate under capacity.
If you have any questions regarding this analysis, please contact Ron Ramos at 925-357-3403.
1 Intersection Levels of Service are defined based on control delay at an intersection. As defined by the FHWA, control delay is the portion of delay that is attributable to the control device (the signal, its assignment of right-of-way, and the timing used to transition right-of-way in a safe manner) plus the time decelerating to a queue, waiting in queue, and accelerating from a queue.

Average and 95th Percentile Queues
The average queues represent the typical queue a driver is expected to encounter. The 95th percentile queue, also referred to as the design queue, is used to determine the recommended storage length so that queues are accommodated approximately 95 percent of the time.
Average and 95th percentile queues for Lincoln Avenue/California Boulevard, Lincoln Avenue/Jefferson Street, Lincoln Avenue/Soscol Avenue are summarized in the morning peak hour queue summary table below. Detailed queue worksheets can be found in the next tables.

Notes: Bold text indicates queue exceeding storage length.
Source: Fehr š Peers, 2025
As shown in the morning peak hour queue summary table, the project increases average queues by approximately 50 to 100 feet at most intersection movements. No through-movement queues extend beyond their available storage lengths, indicating that queue spillback between intersections is not expected.
