In Vancouver we've looked at all of our patrol operations in quite extensive detail, because our most expensive resource is the officers who are out there on the streets. We've looked at a number of key performance indicators, but we've boiled them down to a couple of pretty important ones. One is response time to priority-one calls. At one point in time it was 13 minutes to a call in progress, a crime in progress, and we've managed to get that down to about nine minutes or eight minutes.
We also aim for a 50% proactive policing time ratio, so when officers are going call to call, whether it's a routine burglary report or whether it's processing an impaired driver or arresting somebody for a violent crime, they're tied up on a call. We're trying to get them free from that tied up status to about half of their time in which they're engaged in proactive policing, which is preventative patrols, street checks of gang members, or walking into high-crime areas.
More specifically, it's not 50% of the time in which they do whatever they want. Because we're reviewing crime hot spots in our latest data on a temporal and a geographical basis, we will instruct our officers what areas they need to focus on during that proactive policing time we're aiming for.
