Automated traffic enforcement (ATE) is one of many safety countermeasures that can be used to enhance roadway safety. Automated enforcement may involve the enforcement of red-light running violations and speed limit violations. The City of Cedar Rapids uses ATE systems to enforce red-light running and speed violations at three signalized intersections on the primary highway system. In addition, the City uses ATE systems to enforce speed violations at four locations along United States Interstate 380 (I-380).  There are two additional locations where the ATE system is in place, including the intersection of 42nd Street and Edgewood Road NE and the intersection of Center Point Road and Collins Road ramp (north side of Highway 100).  A list of all locations is available below.  The Police Department also uses a mobile photo radar vehicle that is typically deployed to areas where citizens are concerned about speeding violations in their neighborhood.

The use of automated traffic enforcement has resulted in a reduction in both crashes and crashes with injuries.  The system advances public interests in traffic safety and the safety of emergency responders.

If you receive a violation notice in the mail, please follow the instructions included with the citation for the proper procedures to review the violation, pay the citation, or contest the citation.  Additional information is also available through our website:

Billing Error for Citations For Infractions Between July 14-19, 2020

On July 27, Police Department staff found a clerical error by Sensys Gatso, the company that the City contracts with to provide automated traffic enforcement services.  The error was discovered by a regular review of citations that have been mailed to red light or speeding violators.  The clerical error involved a zero dollar amount populating the Amount Due field on the Notice of Automated Traffic Citation letter that was mailed to several violators who were issued a notice of violation for an infraction between July 14-19, 2020.  All of the infraction, plate information, and other details that police officers reviewed was disseminated correctly.  The only portion of the violation notice that was incorrect was the Amount Due.  For example, a speed of 67 mph in a 55 mph zone should have generated an amount due of $75, but it showed zero as the Amount Due in the incorrect notices that were sent. Sensys Gatso was alerted to this error and is in the process of re-issuing violations with the correct amount in the Amount Due field, along with a cover letter explaining the error.  If you have any questions, please feel free to contact us at atecedarrapids@cedar-rapids.org

Monthly Reports

The Police Department is committed to providing information to the public about the Automated Traffic Enforcement (ATE) system by providing a monthly report.  ATE is an important law enforcement tool for reducing both the number of crashes and crashes with injuries as the result of speeding and red-light running violations.  Monthly reports will be published that summarize the number of speeding and red-light violations, if applicable, at each location where the ATE system is in place.  The reports will detail the top speed recorded at each location.  The reports also include citations issued by residency of the vehicle owner. Crash statistics will also be updated monthly.
