# From 30.000 feet

**od2trips** imports O/D-matrices and splits them into single vehicle
trips.

- **Purpose:** Conversion of O/D-matrices to single vehicle trips
- **System:** portable (Linux/Windows is tested); runs on command line
- **Input (mandatory):**
  - A) O/D-Matrix
  - B) a set of districts
- **Output:** A list of vehicle trip definitions
- **Programming Language:** C++

# Usage Description

od2trips maps traffic that is defined via origin and destination zones
onto the edges of a network. For details, see
[Demand/Importing_O/D_Matrices](Demand/Importing_O/D_Matrices.md).

### Random Number

All applications of the **SUMO**-suite handle randomisation options the
same way. These options are discussed at [Basics/Using the Command Line
Applications\#Random Number
Options](Basics/Using_the_Command_Line_Applications.md#random_number_options).

| Option | Description |
|--------|-------------|
| **--random** {{DT_BOOL}} | Initialises the random number generator with the current system time; *default:* **false** |

# Notes

* The option --vtype only works when "--od-matrix-files" is used. For "Amitran" format, this is given by the "id" property of "actorConfig".
* With use of netedit it is possible to observe the demand amount distribution of edge-based or TAZ-based relations [network/TAZ related data](Netedit/editModesData.md).
