The Traffic Bureau is currently staffed with a Sergeant, four road officers, one desk officer, one motor carrier officer (commercial truck enforcement), and two motorcycle units. All nine have been trained in traffic crash investigations - which is the primary focus of this bureau. Secondary responsibilities include investigations of traffic related crimes and their prosecution, selective enforcement activities, traffic crash pattern analysis, engineering enhancements for improved traffic flow and increased safety, breath test instrument calibrations, school crossing guards and planning board and zoning board research.

The Traffic Bureau Sergeant is an ad-hoc member of the Livonia Traffic Commission and attends all meetings.

As a result of the success of the Strategic Traffic Accident Reduction (STAR) program since 2003, traffic safety programs of the bureau were expanded in 2006. Using the same approach as STAR did by employing the "three E's" of traffic safety (Education, Engineering, and Enforcement), evaluation of the City's traffic signs and signals began. Evaluation was based on compliance with the Manual on Uniform Traffic Control Devices adopted by the State of Michigan in 2005. As of September 2009, the entire City's 36 square miles have been completed, and is in compliance with State Law.  Despite the initial negative reaction from some citizens, traffic flow has improved, traffic violations in these areas have decreased, and overall safety has increased. Traffic crashes have been reduced by 50% since the beginning of the Police Department's traffic safety initiatives from mid-2003 to May of 2009 (from 13 to 6.5 a day).

Another expansion program was the start of the Safe Routes 2 School program. This international program encourages students to walk and bike to school for increased physical activity, enhanced attention span for their studies, and reduced traffic congestion near and on school property. The Traffic Bureau and Livonia Public Schools teamed up to begin this initiative at Coolidge and Rosedale schools. This effort included evaluation of every K-4 school zone area in the City. As a result, numerous enhancements were performed in these areas this summer that improved pedestrian and vehicular safety in and around the schools.
