Supervision of traffic operations is a responsibility shared by individual MPs, patrol supervisors, desk sergeants, MP duty officers (MPDOs) and the provost marshal (PM). All personnel involved in traffic operations must accomplish the following:
The MP supervisor acts as a coordinator of all traffic activities during a given time. Teamwork among all on-duty MPs is imperative. In areas where there are not adequate standing policies, the supervisor must provide guidance on the spot. This guidance may be needed in the following situations:
Fixed traffic points
The following principles of traffic planning should be considered when establishing traffic control operations.
Such areas on an installation may include the headquarters, residential, barracks and commercial areas. The following actions will insure their integrity:
Traffic on roadways should be reduced to avoid congestion. Some proven techniques are:
Primary Circulation System
The traffic plan should establish major routes to bear most of the traffic load. Primary routes should pass around the borders of functional areas to preserve area integrity. Interconnecting routes should also skirt the boundaries of major areas. To discourage unnecessary use of roads in troop or residential areas, make the roads circuitous or dead end. One-way roads reduce accidents.
One-Way Reversible Roads
One-way roads may improve traffic flow, especially if reversible--one-way in for mornings and one-way out for afternoon. Narrow roads can carry a greater volume of one-way traffic than two-way. One-way roads help reduce congestion at intersections where there are many left hand turns or accidents. Temporary one-way roads during morning and evening rush hours may reduce congestion and increase traffic flow. Eliminating curb parking on two-way roads may eliminate the need to establish one-way roads.
Speed zones should be determined by the areas the road passes through. Consider the following criteria before setting speed limits:
- Each speed limit should safely handle traffic, allowing for sufficient stopping distance between hazards.
- Maximum speeds should follow the 85th percentile rule, and minimum speeds should follow the 15th percentile rule (see Speed Studies, Chapter 22).
- Reasonable speed limits encourage driver compliance.
- Adopt the Uniform Vehicle Code 30 mph speed or the state assimilated speed for urban type roadways.
- Unnecessarily restrictive speeds may be ignored by drivers, requiring greater and unnecessary enforcement efforts.
Reviews of traffic studies, patrol reports, and accident investigations may lead to recommendations for improving traffic safety. Such recommendations include:
Special events often generate heavy traffic volume. Traffic control is possible with planning based on the following considerations:
Routes to the event should be direct.
Main routes should terminate at parking areas.
Special routes should be marked for emergency vehicles and operators briefed on these routes.
A special traffic plan should be publicized through the installation bulletin and leaflets.
Normal traffic should be detoured around the area.
Directions and guide signs should be used extensively.
MP planning support to local police during disasters should consider the following:
Military Police must be concerned with provisions of the Posse Comitatus Act during off-post disaster operations. Consult your local staff judge advocate office for details.
