	When conducting a violation study, all approaches shall be evaluated to determine if one approach or all approaches are experiencing similar rates of red-light violations (ratio of violations to the approach volume). A violation study will be completed for each approach of the intersection and will be conducted for a duration of at least 12 consecutive hours between the hours of 6:00 am and 6:30 pm or as directed by the engineer. The start time of the violation study may vary between 6:00 am or 6:30 am depending on traffic conditions of the area and should be a representative sample of traffic volume for that specific location. Violation information shall be provided by the city and/or county. The information shall be reviewed by ~~MoDOT~~ and engineering judgment shall be used to determine if the violation study, in conjunction with the crash data, warrants the use of red-light violation cameras.

In addition, if the crash warrant is not met and the city and/or county still wants to proceed with the installation of cameras, a violation study shall be conducted and the request be sent to the State ~~Traffic and~~ Highway Safety Engineer for further review.

	Severe crashes at signalized intersections are usually a result of non-compliance with a traffic signal. Automated enforcement, when used correctly, is an effective tool for reducing crashes at signalized intersections. The objective of using the cameras is to improve intersection safety. However, not all intersections are candidates for automated enforcement.		Severe crashes at signalized intersections are usually a result of non-compliance with a traffic signal.

	To ensure red-light violations are mitigated as completely and as feasibly possible, state highway intersections selected for installation of automated red-light violation enforcement equipment will undergo an engineering review and, if needed, a violation study prior to the installation of automated red-light violation enforcement equipment. MoDOT will conduct the engineering study to ensure the cameras will not impact the existing signal operation and meet a need for their installation. The city and/or county will provide the information from the violation study.
