About this data
Source: UC Berkeley SafeTREC's crash database (TIMS), which uses California's statewide police crash reports. It covers Jan 2015 – Jun 2026 and includes only crashes where someone was hurt or killed. 2026 is partial (through June). 76 of the 1,057 crashes killed or seriously injured someone.
More crashes on a street doesn't mean that street is the most dangerous to walk. Busy streets have more crashes partly because more people use them. Use the map to know where to take extra care, not as proof a route is safe.
"After school" means weekdays, 3:00 to 5:59 PM, all year (the records don't say whether school was in session). Kids are people 17 and under, older adults 65 and over. Ages come from the police report.
To protect the people involved, crashes show only the month, year and hour, not the exact date or report number.
3 crashes have a recorded location far outside the city (likely a data-entry error), so the map shows 1,054 of the 1,057.
Totals of people hurt include everyone in the victim records. A few crash reports have no time or place, so the time-of-day figures count only people whose crash time is known.
A crash counts toward an intersection if it happened within 250 ft of it. Crashes farther from any intersection are mid-block. This gives the same top-three counts TIMS publishes (39, 37 and 33).
14 people were killed. The map shows 13: 1 more death (a pedestrian aged 65 or older, in 2025) is in the records but has no time or location, so it isn't mapped. It is counted in the 65+ totals.
Serious-injury counts before 2018 are low because of a change in how injuries were recorded. Compare serious-injury trends from 2018 on only.
