5.4        Maintenance of Traffic

5.4.1            Maintenance of Traffic (MOT) Plans

Maintenance of Traffic (MOT) Plans are required when work requires road/lane closures. Road/Lane closures or roads otherwise impacted by the Task require approval by the agency having jurisdiction over said road; in most cases this is Maryland State Highway Administration (SHA) or the County (Anne Arundel County for BWI Marshall tasks, Baltimore County for MTN tasks.) All Tasks impacting roads, whether or not owned/maintained by the MDOT MAA, shall be coordinated with and approved by the Office of Ground Transportation.

For projects impacting SHA roads, the following SHA groups, at minimum, shall be coordinated with:

A.     Office of Traffic Safety (OOTS), for traffic signaling

B.     Office of Materials Technology (OMT), for materials testing

C.      District 5 Utility Permits, for any digging of utilities in Anne Arundel County

D.     District 4, for any digging of utilities in Baltimore County (MTN)

If MOT impacts SHA, Consultants shall submit the plans and a “District Office Permit” application to the District Utility Engineer at SHA for approval. Upon approval, SHA will issue a District Office Permit. SHA does not return signed drawings upon approval.

5.4.2            Traffic Cones

Twelve inch (12”) traffic controlling cones shall not be used for projects at BWI Marshall and Martin State Airports. State Highway Administration (SHA) studies have found that larger cones decrease accident rates. For slower traffic, 18” cones shall be used. For highway and nighttime traffic, 28” cones shall be used. In addition, during nighttime work, 28” cones must have reflective collars. This information may be obtained from SHA’s Traffic Control Booklet #6.
