Comprehensive Safety Action Plan (CSAP)
The City of Concord is committed to eliminating traffic fatalities and severe injuries on our streets. We are developing a data-driven plan to identify high-risk locations and implement proven strategies that improve safety for all road users.
About the Project
Building Safer Streets for Every Road User
Through the Safe Streets and Roads for All (SS4A) program, Concord is combining crash data, roadway analysis, and community engagement to prioritize investments that improve safety for all.
Data-Driven Analysis
Five years of collision records reveal high-injury corridors, intersections, and patterns across the City.
Community Engagement
Residents across all neighborhoods share lived safety experiences that complement the crash data.
All Road Users
The plan addresses pedestrians, cyclists, seniors, transit riders, and drivers at the highest-risk locations.
Actionable Projects
Specific, fundable improvements — crosswalks, signals, lighting, bike lanes — prioritized by safety impact.
Safe System Approach
Streets designed so that human errors don't result in death, making the system more forgiving for all.
Federal Partnership
SS4A funding positions Concord for future implementation grants to deliver real capital improvements.
Federally Funded: This plan is supported by the U.S. Department of Transportation's Safe Streets and Roads for All (SS4A) grant program. Learn more ↗ (opens in new window)

Overview
What the Data Is Telling Us
Five years of data reveal consistent patterns across time, location, and contributing factors — spanning ten analytical dimensions.
Fatalities Down 37%
6.0/yr pre-2020 → 3.8/yr in 2021–2025. 11 fewer fatalities over five years.
VRU Severity
26% of involvements but 60% of KSI. Ped KSI rate in dark: 42%.
Bicycle Safety
14.1% KSI rate. 89% at intersections. Rate: 2.8%–27% by year.
Signal Intersections
57% of collisions at signals → 89 KSI. Broadside + rear-end = 724.
Lighting Factor
63% of fatal in dark. Ped night KSI: 42%+ — 5× citywide avg.
Positive Trend
Alcohol collisions down 50%: 60 (2023) → 30 (2025).
KSI Rate & Volume by Year
Blue bars = KSI count by year · Yellow line = KSI rate %. 2023 and 2024 showed the lowest rates of the period, with 2025 returning closer to prior levels.

KSI Rate vs. Total Collisions — 5-Year Trend
Line = KSI rate % (right axis) · Bars = total injury collisions (left axis). KSI rate improved notably in 2023 and 2024 — the two best years on record. Total collision volume also declined over the period.
Fatal Collisions by Mode
Pedestrians account for 37% of fatalities despite representing ~5% of vehicle miles traveled.
Fatal Collisions by Lighting
63% of fatal events occurred in dark conditions — even where street lighting was present.
The Three Priority Levers
Across 19 fatal events, three independent contributing dimensions each appear in roughly one-third of cases. Some events involve multiple factors simultaneously, indicating overlapping risk profiles.
Lighting Conditions
Present in 12 of 19 fatal events (63%)
9 of 12 dark-condition fatalities had street lighting present — lighting alone does not eliminate severe crash risk.
Pedestrian Involvement
Present in 7 of 19 fatal events (37%)
Vehicle-striking-pedestrian is the most common fatal type (8 events). Monument Blvd, Clayton Rd, and Willow Pass Rd have the highest pedestrian KSI concentrations.
Alcohol Involvement
Present in 7 of 19 fatal events (37%)
Alcohol crashes are 3.9× more likely to be fatal (3.0% vs 0.76%). Alcohol-involved collisions dropped 50% from 2023 to 2025 (60→30).
Key Analytical Note
Hit-and-run recorded in 4 of 19 fatal events (21%) — driver departure adds investigation complexity beyond primary collision factors.
Fatal Collisions by Year — With Contributing Factor Breakdown
2022 had 7 fatal events (highest year). 2024 had 1 (lowest). 2025 recorded 5 fatal events.
Severity
Severity Landscape
164 of 1,804 injury collisions (9.1%) resulted in KSI outcomes — 19 fatal and 145 severe injuries. Tracking KSI rate shows whether streets are getting safer.

Temporal Patterns
When Collisions Happen
Volume peaks at 3 PM but highest severity rates occur late-night and early morning. Understanding both patterns is essential.
Hourly Collision Pattern — Injury Volume vs. KSI Count
Blue bars = injury collisions (left axis). Yellow line = KSI events (right axis). The PM peak (2–5 PM) accounts for 420 injury and 36 KSI collisions between 2021 and 2025.
Late Night / Early Morning: Highest KSI Severity Rate
1 AM (32%), 5 AM (27%), 11 PM (21%) — KSI rates 3–4× higher than PM peak. Low-volume nighttime collisions are disproportionately severe.
School Hours: High Volume + VRU Exposure
7–8 AM and 3–4 PM combined: 496 injury collisions, 39 KSI, 54 pedestrian, 44 bicycle crashes.
Monthly Collision Pattern — Injury Volume and KSI
Volume peaks in August–October. KSI peaks in June (19 events) and December (17 events) — reflecting distinct risk mechanisms: summer speed/VRU exposure and winter darkness/alcohol.
| Month | Injury | KSI | KSI Rate | Primary Risk Context |
|---|
Day-of-Week — Injury Volume and KSI Events
Thursday has the highest injury volume (310). Monday and Sunday each record 28 KSI events — the highest of any day despite lower overall volumes, reflecting a distinct weekend and Monday collision pattern.
Weekend KSI Rate Observation
Sunday: 28 KSI from 206 collisions (13.6% rate) vs. Thursday: 18 KSI from 310 collisions (5.8%). Weekend overnight conditions amplify severity.
KSI Rate Heatmap — Day × Time Period
Each cell shows the KSI rate for that day/time combination. Darker = higher KSI rate per collision. Late night and overnight windows consistently show the highest rates regardless of day.

Signalized vs. Unsignalized Intersections
1,032 signalized intersection collisions (57% citywide) produced 89 KSI at 8.6% rate. 493 unsignalized intersection collisions produced 51 KSI at 10.3% rate. Signal locations concentrate 75% more absolute KSI — making signal operations the higher-priority focus.
Signalized Intersections
1,032 collisions · 89 KSI · 8.6% rate
Signal violations contributed to 292 collisions and 23 KSI. Broadside collisions at signals total 450 — 65% of all broadside crashes citywide.
Unsignalized Intersections
493 collisions · 51 KSI · 10.3% rate
Modestly elevated KSI rate vs. signalized. Speed differentials and sight-line conditions are the primary collision factors.
Roadway Segments
286 collisions · 22 KSI · 7.7% rate
Fewer crashes but higher single-vehicle run-off and head-on rates. Alcohol and night conditions more prevalent — concentrated on Kirker Pass, Port Chicago Hwy, and Ygnacio Valley.
Vulnerable Road Users
Pedestrians, Cyclists & Motorcyclists
Pedestrians, cyclists, and motorcyclists bear disproportionate crash severity relative to their roadway share. Each mode shows distinct risk patterns.
Mode — Share of Injury Collisions vs. Share of KSI Outcomes
The gap between injury share and KSI share reveals the severity disparity each mode faces. A larger gap indicates higher per-collision KSI rate relative to exposure.

Darkness Dramatically Amplifies Risk
52 dark-condition ped crashes = 27% of total but 48% of ped KSI. Dark-condition ped KSI rate: 42.3% — the most pronounced severity differential.
Pedestrian Action at Time of Collision
Where the pedestrian was and what they were doing when the crash occurred. In-crosswalk crashes represent 47% of total pedestrian collisions.
Three Observed Pedestrian Crash Patterns
Pattern A — Crosswalk-Based Crashes
89 crosswalk crashes (47%) with 21.3% KSI rate. Signal timing, sight distance, and driver yielding are key factors.
Pattern B — Mid-Block / In-Road Crashes
43 mid-block crashes with 39.5% KSI rate — highest of any category. Concentrated on Clayton, Monument, and Willow Pass.
Pattern C — Darkness at Intersections
42 dark intersection crashes with 42.9% KSI rate — the highest-severity pedestrian sub-cluster.

Contributing Factors
Contributing Factors Analysis
Every collision is coded with a primary contributing violation. Comparing volume vs. severity reveals where outcomes are disproportionate.
Violation Category — Injury Collisions vs. KSI Events
Blue = Injury Collisions Yellow = KSI Events. DUI and Pedestrian Right-of-Way have notably elevated KSI relative to collision volume.
Alcohol-Involved Collisions by Hour
59% of alcohol collisions occur between 3 PM and 2 AM. The 9 PM–2 AM window is the peak concentration for late-night alcohol-related collisions.
Unsafe Speed — Volume and Severity Context
Unsafe speed: 418 collisions (23% of total). 85% of KSI in clear weather, 90% on dry roads — adverse conditions are not the primary driver.
Violation Category Summary
| Violation Category | Injury Collisions | KSI Events | KSI Rate | % of All KSI |
|---|---|---|---|---|
| Unsafe Speed | 418 | 23 | 5.5% | 14.0% |
| Traffic Signals & Signs | 292 | 23 | 7.9% | 14.0% |
| Improper Turning | 270 | 23 | 8.5% | 14.0% |
| Auto Right of Way | 238 | 18 | 7.6% | 11.0% |
| DUI – Alcohol | 139 | 20 | 14.4% | 12.2% |
| Ped Right of Way | 89 | 13 | 14.6% | 7.9% |
| Pedestrian Violation | 53 | 22 | 41.5% | 13.4% |
| Following Too Closely | 61 | 1 | 1.6% | 0.6% |
| Wrong Side of Road | 46 | 5 | 10.9% | 3.0% |
Pedestrian Violations — Context
41.5% KSI rate — highest of any category. Reflects crash coding, not legal fault. Many occur on arterials with limited crossing options.
Hit-and-Run Collision Pattern
Hit-and-Run by Year
213 hit-and-run collisions between 2021 and 2025. The 2023 peak of 60 events (15.7% of all crashes that year) declined to 30 in 2025 — the lowest of any year in the data.
Pedestrian H&R Collisions
35 of 213 H&R events involve pedestrians
18.4% of ped collisions are H&R. Highest proportion of unwitnessed severe injury crashes in the dataset.
Positive Trend: H&R Declining
H&R collisions: 60 (2023 peak) → 30 (2025) — 50% reduction, mirroring the alcohol decline.
Demographics

Age Pattern Observations
Based on 1,080 records with age data
Drivers aged 15–29 account for approximately 33% of driver records where a violation was cited — higher than their share of the driving population. The 15–19 sub-cohort shows elevated involvement relative to their licensed driving population. Drivers aged 70+ show involvement broadly proportional to their population, with a 9.3% KSI rate near the citywide average. Missing age data (96 records coded as unknown) limits the precision of age-based analysis.
Collision Profiles
Ten Citywide Collision Profiles
Ten citywide collision profiles were developed from the 2021–2025 dataset, capturing the most prevalent and severe recurring patterns. Each profile characterizes a distinct cluster defined by collision type, contributing factors, location, and time-of-day attributes. Profiles are sorted by total collision volume.

Reading the Profiles
Blue left border = standard priority. Red left border = elevated KSI rate (profiles 4, 8, 9, 10). Each profile's three sub-metrics reflect the dominant co-occurring conditions within that crash pattern — they are not mutually exclusive; individual collisions may appear in more than one profile. Total collision counts reflect all injury collisions where the named condition was a primary or contributing factor.
