Transport - Segment - Delivery

Understanding the Structure of a Transport in Dashdoc

1. What is a Transport?

A Transport is the main object in Dashdoc. It represents a shipping operation managed by a single shipper and executed by a single carrier.

A transport must :

• Always include at least one Delivery and at least one Segment.

A Transport can:

• Contain several Deliveries (all from the same shipper).

• Contain several Segments (each representing a part of the truck’s route).

2. Key Concepts

Delivery : What is shipped

A Delivery represents the path of the goods from one origin to one destination. It describes what must be transported for a client.

Each Delivery:

• Belongs to one Transport.

• Has one origin and one destination.

• Contains one or more Loads → the goods being shipped.

💡 Example: A delivery from warehouse A to warehouse B carrying 10 pallets of goods.

🚛 Segment — How it’s shipped

A Segment represents the path taken by the truck. It describes how the deliveries are physically executed.

Each Segment:

• Has one origin and one destination.

• Specifies the trucker, vehicle, and/or trailer license plates assigned to that leg.

• Always starts where the previous segment ended.

⚠️ Important:

• A single Delivery cannot be split across multiple Segments.

• If multiple Deliveries are needed (e.g. multiple clients or destinations), then multiple Segments are required to represent each delivery leg.

3. Simple Example : One Delivery, One Segment

Scenario: A carrier ships goods from warehouse A to client B using one truck.

Object	Origin	Destination	Description
Delivery 1	A	B	Goods from A to B
Segment 1	A	B	Truck route from A to B

Here, both the Delivery and the Segment share the same route:

• The Delivery holds the commercial and shipping details (client, goods, etc.).

• The Segment holds the operational details (driver, truck, plates, etc.).

4. Complex Example : Multiple Deliveries to Different Clients

Scenario: The shipper wants to deliver goods from a warehouse A to three clients located at B, C, and D. One truck will make all deliveries in sequence.

Stop	Description
A	Shipper’s warehouse (loading)
B	First delivery stop
C	Second delivery stop
D	Third delivery stop

Deliveries

Delivery	Origin	Destination	Description
Delivery 1	A	B	Goods for Client 1
Delivery 2	A	C	Goods for Client 2
Delivery 3	A	D	Goods for Client 3

Segments

Segment	Origin	Destination	Description
Segment 1	A	B	Truck drives from A to first client
Segment 2	B	C	Truck continues to second client
Segment 3	C	D	Truck finishes at third client

Complex transport example

🧩 Connections:

• Deliveries represent the intended paths of the goods (A→B, A→C, A→D).

• Segments represent the actual route of the truck (A→B→C→D).

• Each Segment starts where the previous one ends, forming a continuous trip.

• Each Delivery corresponds to one drop-off point.
