# San José Street Safety Atlas — research and press kit Study period: **2020–2024**. Official snapshots downloaded **6 September 2026**. Published by GJEL Accident Attorneys. This analysis is independent of the City of San José, CHP, Caltrans and other source agencies; their publication of source data does not imply endorsement. ## Story angles ### San José's highest crash counts and highest serious-crash counts point to different intersections Capitol Expressway & Story Road and King Road & Story Road tie for the highest total in the eligible City intersection table, with 87 crashes each during 2020–2024. Frequency shows the scale of reported collisions. It does not account for how many people or vehicles pass through a place. Capitol Expressway & Quimby Road leads the eligible intersection table with 8 KSI crashes among 56 total crashes during 2020–2024. Those crashes recorded 10 severely injured people and 0 fatalities. KSI counts crashes with at least one person killed or severely injured; it is a different measure from the number of injured people. **Use with the finding:** Keep the shared frequency lead and the eligible-intersection definition. Do not headline this as the highest risk per trip. **Claim references:** intersection-capitol-expressway-story-road.total, intersection-king-road-story-road.total, intersection-capitol-expressway-quimby-road.ksi, intersection-capitol-expressway-quimby-road.total, intersection-capitol-expressway-quimby-road.severe, intersection-capitol-expressway-quimby-road.fatalities. ### A walking and cycling view reveals another serious-crash pattern Capitol Avenue & McKee Road leads the eligible intersection table for pedestrian-or-bicycle-involved KSI crashes, with 6 during 2020–2024. Across the retained City sample, pedestrians were recorded in 5.63% of crashes and 28.68% of KSI crashes. Bicycle involvement was recorded in 5.23% and 12.91%, respectively. These recorded-positive shares include unknown-mode records in their denominators. They describe involvement, not which person was injured or the risk per trip. **Use with the finding:** Do not relabel mode-involved crashes as pedestrian or cyclist injuries. Publish unknown coverage alongside the shares. **Claim references:** story.vru.union_ksi, city.mode.pedestrian.crash_share_pct, city.mode.pedestrian.ksi_share_pct, city.mode.bicycle.crash_share_pct, city.mode.bicycle.ksi_share_pct. ### How recorded serious crashes overlap San José's Priority Safety Corridors 631 of the 1224 retained City KSI crashes (51.55%) occurred within 30 meters of official Priority Safety Corridor geometry. Monterey Road has the highest nearby KSI count among those official corridors in this analysis, with 55. Nearby corridor counts may overlap. **Use with the finding:** This is a contemporary analytical proximity comparison, not an assessment of whether a project caused a change or a reproduction of the City's corridor-selection method. **Claim references:** city.psc.ksi, city.psc.ksi_share_pct, psc-monterey-road.ksi, psc-monterey-road.rankings.ksi_crashes. ## Available research material - The frozen canonical CSV, one row per crash, with preserved source identities and nullable fields. - Full intersection, road-segment and corridor tables; annual, condition and road-user summaries. - Raw official source snapshots, a source register, reproducible scripts, GeoJSON and a detailed QA report. - Three editorial story records and twenty curated location records with annual and mode coverage. - An editorial citation register linking every numerical value in these generated records to its exact calculation. ## Publication graphics - [Frequency and KSI comparison](frequency-versus-ksi.svg): both frequency leaders and the highest KSI intersection; different chart scales are labeled. - [Walking and cycling involvement](road-user-shares.svg): shares of all City crashes and all City KSI crashes, with unknown classifications disclosed. - [Priority Safety Corridor proximity](priority-corridors.svg): the union-based overall KSI share and leading individual corridor counts. All three SVGs are editable vector graphics with accessible titles/descriptions, dated source notes and unit distinctions. Keep those notes when republishing. `press_graphics_manifest.json` connects the graphics to exact claims and official URLs. Generate them with `.venv/bin/python atlas-upgrade/editorial/generate_press_graphics.py` after generating the editorial JSON. Optional PNG copies are in `previews/`; `render_press_previews.cjs` regenerates them using Node.js and sharp. ## Interview and press contact The publisher must designate a research contact before public press outreach. No outreach has been sent and no interview availability, independent review or agency endorsement is asserted. ## Citation GJEL Accident Attorneys. San José Street Safety Atlas: 2020–2024 official-source study. Data snapshot 2026-09-06. Cite the exact location report, metric definition and access date; link to the published version and its methodology. ## Wording to preserve - City records cover SJPD streets and county expressways inside the current official municipal boundary. - Highway records are a reviewed subset, not complete San José highway coverage; CHP 2024 remains provisional. - Road-user classification and actual mode-specific injury attribution have different coverage. - Historical counts do not establish causation, fault, road defects or exposure-adjusted risk. - The original user-described research package remains unavailable and has not been inspected. - Use 'recorded crashes' or 'KSI crashes in this selection.' Frequency does not establish highest risk per trip. - Use 'pedestrian-involved KSI crashes' when that is the metric; it does not mean that every seriously injured person was a pedestrian. - Do not add overlapping Priority Safety Corridor counts together. - Observed year-to-year changes are descriptive; this release does not estimate the effects of safety projects. ## Correction requests A correction request should identify the dated edition, report or figure, exact claim and relevant official evidence. Preserve the dated input snapshots. Verify reported errors against source records, publish a dated correction describing the affected metric or geography, regenerate all dependent tables and map assets, and retain the superseded release for reproducible citations. Do not silently replace a published release. ## Source links - [City of San José: Crash Locations archive](https://geo.sanjoseca.gov/server/rest/services/OPN/OPN_OpenDataService/MapServer/512) - [City of San José: Crash Vehicles Involved](https://geo.sanjoseca.gov/server/rest/services/OPN/OPN_OpenDataService/MapServer/513) - [City of San José: Street Intersections](https://geo.sanjoseca.gov/server/rest/services/OPN/OPN_OpenDataService/MapServer/276) - [City of San José: Streets](https://geo.sanjoseca.gov/server/rest/services/OPN/OPN_OpenDataService/MapServer/60) - [City of San José: Vision Zero Safety Corridors](https://geo.sanjoseca.gov/server/rest/services/OPN/OPN_OpenDataService/MapServer/514) - [City of San José: City Limits](https://geo.sanjoseca.gov/server/rest/services/OPN/OPN_OpenDataService/MapServer/372) - [California Highway Patrol: California Crash Reporting System](https://data.ca.gov/dataset/ccrs) - [City of San José: 2025 Vision Zero Action Plan, Council attachment](https://sanjose.legistar.com/View.ashx?GUID=D06949E0-EF76-4BDB-9BF4-F78BA3AFA9E9&ID=13758090&M=F) - [City of San José: Vision Zero program and dashboards](https://www.sanjoseca.gov/your-government/departments-offices/transportation/safety/vision-zero)
