Deadhead

Tractor with an empty trailer. See also "Bobtail" , "Unloaded Distance"

Deadhead Distance

Distance travelled by a tractor with an empty trailer.

Deadweight Tonnage

Total weight a ship can carry.

Declared Value

The value of goods shipped as declared for customs purposes. See also "Order Value".

Deconsolidation

The method by which shipments grouped together in a load are separated at a hub or distribution center into individual shipments for delivery to each of their respective final destinations.

Default

A preconfigured setting that usually reflects the best or most common choice for a particular field.

Deficit Weight

The difference between the actual weight of a shipment and the weight used to rate the shipment in a higher weight range. It is used with a Deficit Weight Freight Class (*DFC) when rating with the Look Ahead option in a multiclass environment.

Delivery Schedule

A cross-reference of itineraries and timetables. Itineraries define a sequence or locations or zones. Timetables define sets of pickup dates and times with corresponding delivery dates and times for each point on the itinerary.

Destination

The intended final location for a shipment. A destination can be a consignee, hub, or distribution center. Also see "Origin".

Dimensional Weight

Dimensional Weight is a tariff condition that you can use when the weight of a shipment does not reflect the actual volume of space taken up by the goods.

For example: A shipment of light bulbs would weigh relatively little compared with the volume of space it takes up. You can set up a tariff to use a Dimensional Weight Factor, which is applied to the volume to arrive at an equivalent weight. The actual weight and the dimensional weight are compared: the greater of the two will be used for rating.

Direct

A shipment that moves from origin to final destination without making any intermediate stops.

Direct Distance

The direct distance between two points. In the context of a point-to-point load, it is the distance that would need to be traveled between the first pick and the last drop on the load without making any intermediate stops. In the context of a round-trip (load or continuous move), direct distance is two times the distance between the location of the first stop and the location that is farthest from the first stop, again measured without allowing for travel to any intermediate stops.

The number of direct miles will vary by transit mode.

For example: The distances by road, rail, air, and ocean between Los Angeles and Miami are very different. However, direct miles are always the shortest distance between the points using the selected mode. In Transportation Manager, land (highway) miles are normally used.

Distance Engine

In Transportation Manager, Distance Engine refers to the unique combination of vendor application (e.g. Rand McNally IntelliRoute ™, ALK Associates PC*Miler ™, i2 Distance) and route type (e.g. shortest, practical, household goods, avoid tolls, etc.).

Distance/Transit Time Override

A value that you can define for distance or transit time between a pair of shipping location addresses for a specific Division and Distance Engine. This would override the value that would be computed by the applicable provided by the Distance Engine.

Distribution Center

A physical location where merchandise is stored, shipped, and received.

Diversion

The instructions received from any authorized source to divert a shipment to a different destination while the freight is in-transit.

Division

A distinct business unit within your organization. In Transportation Manager, freight from different divisions cannot be consolidated onto the same load or trip.

Dock Scheduling

Arranging a specific time and dock location for loading or unloading shipments.

Domain Table

A table in Transportation Manager that contains multiple lists of values.

Domicile

A physical location from which carriers manage their equipment.

Domicile Based Carrier

When Domicile Equipment data has been configured in Transportation Manager, the carrier will be domicile based. This means that all routes for the carrier will be round trips and itineraries will both start and end at a domicile.

DOT

Abbreviation used for the United States Department of Transportation.

Double

The combination of a tractor and two trailers connected in tandem by a converter dolly.

Drayage

The transportation of containerized cargo between ocean ports or rail ramps and shipping docks in Intermodal freight transport.

Driving Rules

A term used to refer to the set of driving regulations that restrict the number of continuous hours of service a driver may log before having to take a break. In the United States, these are sometimes called DOT Rules.

Drop and Hook

Carrier drops a trailer at a location and then picks up another trailer.

Dwell Time

Time spent waiting for the next event. For example: the time between a shipment’s arrival at and departure from a hub; the time spent by a driver waiting for loading or unloading.
