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.
Options#
You may use a XML schema definition file for setting up a od2trips configuration: od2tripsConfiguration.xsd.

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.
