Published activity is not a complete record of every incident. A call for service is not confirmation of a crime. No scanner audio is provided.
Live-call history begins when collection starts. Historical crashes come from a separate MetroPlan / Signal Four dataset. The available years are shown in Crash History; this is not a complete latest-12-month feed. Numbered circles count crashes grouped on the map, not automatically crashes at one intersection. The intersection-only filter uses the source’s intersection-related flag.
Your custom map center stays in this browser. It is never sent to the collector.
