potential enemy activity. MP generally escort convoys containing critical resupply, special ammunition,
sensitive cargo, or distinguished individuals requiring special protection. In areas suffering from a large
amount of pilferage, MP may also escort convoys to preclude diversion of the cargo.
Planners and security element leaders should know what a convoy commander does; how the convoy
is organized; and the role of the HTD or division transportation officer. Since the division transportation
officer (DTO) performs many of the same functions as the HTD, remarks in this lesson pertaining to the
HTD also apply to the DTO unless stated otherwise. The functions and operations of the HTD are
covered in detail in subcourse MP 1028 and MP 1029.
Highway Traffic Division
The HTD controls the use of the main supply route (MSR) network. It is an organization that is a part of
the corps movement control center. In the division it is the division transportation office. Personnel
from other organizations may be detailed to it as required by the situation.
The HTD informs the convoy commander of the restrictions and requirements placed on convoys. It is
the HTD that grants convoy clearances and movement credits. Information concerning convoy support
in the area is provided by the HTD. Such support may include security forces, escort vehicles, fire
support, vehicle recovery and repair, and medical aid. These services are generally provided on an
area basis. As with MP escort, in specific instances, any or all of these services may be provided to a
particular special movement. The HTD maintains up-to-date information on road conditions as well,
and provides that information to those that need it.
The responsibilities of the HTD will vary depending on the expected amount of movement and the
capacity of the road network. It will normally perform most of the following functions, as well as those
discussed in the preceding paragraph:
Formulates and maintains the highway regulation plan and the traffic circulation plan.
Acts as a clearing house for highway status information.
Implements established priorities for highway routing.
Processes route clearance requests.
Establishes procedures for reporting road conditions, highway construction, damage, etc.
Established MSR and alternates.
Issues the traffic circulation overlay and updates it.
