Using LPR technology to scan 3,000+ license plates per day in Greeley, CO


In Greeley, CO, parking enforcement was historically managed by the City’s police department. Manual tire chalking was the primary method used which proved to be ineffective– officers struggled to enforce in wet environments, vehicle owners easily altered chalking marks and there was no way to identify other vehicle issues, such as outstanding unpaid tickets or repeat offenders. An analysis by the City revealed that the top 20 repeat offenders owed $26,000 in parking tickets.

Armed with Passport’s Enforcement Software, Greeley has been able to eliminate manual tire chalking and can now enforce digitally. The City’s LPR (License Plate Recognition) technology allows Greeley to have more accountability in the enforcement space and to cover more ground in a fraction of the time. The City estimates each officer in an LPR vehicle can scan 3,000-4,000 license plates per day.

The technology also gives the new Parking Services division the ability to track abandoned vehicles, alleviating this responsibility from the police department and allowing them to focus on community safety. Officers can easily access data in Passport’s back office system and pull reports to use for evidence in appeals cases. This new and improved enforcement has also encouraged those with permits to park in their identified lots, which has truly helped with availability as shown in the images below.
