RESPONSE TIMES
Since there are varying ways law enforcement agencies calculate “response” times, to goal of this document is to provide our methodology and not just the raw data related to response time. Here is how the Palos Verdes Estates Police Department calculates response times:

When someone calls the police department to report a crime, they provide the dispatcher (in PVE) with certain information. That information is then entered into our dispatch computer system and a “call” is generated. At that time, the “Pre-Dispatch” clock starts ticking. “Calls” are seldom held at dispatch or delayed in a queue, and are assigned to an available officer(s) to respond.

After receiving the call, the dispatcher assigns and dispatches an officer(s) to respond. This starts the officer’s “Travel” response clock. When the officer radios back to dispatch that, he/she has arrived on scene, all clocks stop ticking.
Attached is our Priority I (emergency response) for April 2017

If you are looking at response times from other law enforcement agency be sure to establish what elements establish their “response time.” Some may only calculate and publish the time it took the officer to respond (drive time) to the call and not the time the call was actually received/held at dispatch or in a call queue.
