		+	When using trailer mounted temporary traffic signals on projects, review each site to determine if the temporary traffic signals should be required to be retrofit for traffic actuation.
		+
		+	Temporary traffic signals should be retrofit for actualization when any one or more of the following conditions exist on the project site:
		+
		+	#Traffic volumes that are low enough to create time periods when a vehicle would be held on a normally timed red signal where no opposing traffic is present.
		+	#Traffic volumes that are directional, where directional traffic may be stopped on a red indication before the entire queue can clear the signal.
		+
		+	Construction staff should work with region/TSC traffic and safety staff to determine if the temporary traffic signal location should be considered for actuation.
		+
		+	If it is determined the temporary traffic signal meets the requirements to be retrofit, advise the contractor of the required additions to the temporary traffic signal, and pay for the retrofit as a contract extra work item with a negotiated extra cost.

		+	The American with Disabilities Act (ADA) requires pedestrian pushbuttons be placed strategically to provide accessibility for any person with disabilities. There are mandatory distances for placement of pushbuttons in conjunction with crosswalks. Also, there are traffic signal timing implications for placement of the pushbuttons. Traffic signal installations are designed to specifically accommodate those requirements. Traffic signal pushbuttons can be placed on isolated pedestals or in combination with traffic signal support poles. When a designed pole location is relocated without knowledge or approval of the Traffic Signals Unit, it could result in a violation of the ADA requirements and open the department to litigation. Do not approve changes to traffic signal operations without knowledge or approval of the Traffic Signals Unit. Changes of this nature can have implications to ADA requirements.

 It is the contractor's responsibility to notify MDOT’s Statewide Signal Shop prior to beginning any signal work.  Traffic signal projects include a note in the project plans that state the following, "Contact MDOT (and any other maintaining agency) seven (7) working days prior to start of construction and seven (7) working days prior to signal activation.”  Appropriate contact information is indicated in the plan notes.  The seven day time frame will allow for coordination between the contractor and the Statewide Signal Shop for installation and inspection of traffic signal work.  It is recommended that these notification requirements be discussed at the pre-construction meeting.
