AVIS Information

The City of Evans is implementing an Automated Vehicle Identification System (AVIS) to improve traffic safety, reduce speeding and encourage compliance with posted speed limits.

The program uses fixed cameras and mobile camera trailers to measure vehicle speeds, document potential violations and count traffic.

The following frequently asked questions explain how the technology works, what information is recorded, who can access that information and how the City protects the information collected.

Speed Camera Faqs

AVIS cameras capture video and still images of vehicles and license plates. Recorded information may include visible exterior characteristics such as vehicle color, body style and other distinguishing features.

The cameras are directed at vehicles and license plates, not intentionally at drivers or occupants. The system does not record audio.

Vehicles traveling through an AVIS camera location may appear in video recordings, even when they are not speeding.

However, if a vehicle is not detected exceeding the speed limit, the system does not create a separate still image of its license plate.

The City's speed enforcement system does not include additional automated license plate recognition (ALPR) functionality.

Video recordings are available for a limited period and may only be accessed for lawful, authorized purposes consistent with department policy.

Authorized uses may include:

• Investigations

• Reviews of contested violation notices

• Other authorized official duties

Access is limited to what is reasonably necessary for the specific purpose. Recordings may be preserved when needed for legal proceedings or other legal obligations.

Direct access to the AVIS system is restricted to authorized Evans Police Department personnel and authorized service-provider personnel.

Service-provider access must be lawful and limited to what is reasonably necessary to provide authorized services.

Evidence supporting confirmed violations is provided to the registered vehicle owner and, when necessary, court personnel.

Any other disclosure must comply with applicable law and department policy.

The Evans Police Department maintains policies governing access to and use of AVIS information.

These safeguards include:

• Authorized access: Access must be lawful, permitted under department policy and connected to an official purpose.

• Documented searches: Non-routine searches require specific documentation.

• Activity monitoring: System access is subject to auditing, and available activity logs are maintained.

• Regular oversight: Quarterly audits and annual reviews are required.

• Restrictions on misuse: Personal or curiosity-based searches are prohibited. Suspected misuse is addressed through established complaint and internal affairs procedures.

These measures are intended to ensure AVIS information is accessed and used appropriately.

Authorized department personnel review every potential speeding violation before a notice is issued.

Vehicle owners who receive a violation notice may request an administrative review. If the matter remains contested, recipients may pursue a court hearing.

Research suggests that automated speed enforcement can help reduce crashes near camera locations.

A Cochrane systematic review examining 35 studies found that most studies reporting local crash reductions identified decreases of approximately 14% to 25% near speed camera sites.

Results vary by location, roadway conditions and program implementation.

Yes. Implementation of the City's AVIS technology adheres to all applicable federal and Colorado state statutes.

The program operates within applicable legal requirements governing automated speed enforcement, use of recorded information and the issuance of citations.

Each year, the City of Evans is required to disclose information about its automated speed enforcement program.

Annual reporting includes information such as:

• The number of citations issued

• Revenue generated by the program

• Summaries of designated enforcement corridors

• Other information required by applicable law

These reporting requirements provide transparency about the operation and results of the AVIS program.
