od2trips

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.

Options#

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

Time#

Option Description
-b <TIME>
--begin <TIME>
Defines the begin time; Previous trips will be discarded; default: 0
-e <TIME>
--end <TIME>
Defines the end time; Later trips will be discarded; Defaults to the maximum time that SUMO can represent; default: -1

Processing#

Option Description
-s <FLOAT>
--scale <FLOAT>
Scales the loaded flows by FLOAT; default: 1
--spread.uniform <BOOL> Spreads trips uniformly over each time period; default: false
--different-source-sink <BOOL> Always choose source and sink edge which are not identical; default: false
--vtype <STRING> Defines the name of the vehicle type to use
--prefix <STRING> Defines the prefix for vehicle names
--timeline Uses STR[] as a timeline definition
--timeline.day-in-hours <BOOL> Uses STR as a 24h-timeline definition; default: false
--no-step-log <BOOL> Disable console output of current time step; default: false

Defaults#

Option Description
--departlane <STRING> Assigns a default depart lane; default: free
--departpos <STRING> Assigns a default depart position
--departspeed <STRING> Assigns a default depart speed; default: max
--arrivallane <STRING> Assigns a default arrival lane
--arrivalpos <STRING> Assigns a default arrival position
--arrivalspeed <STRING> Assigns a default arrival speed

Report#

All applications of the SUMO-suite handle most of the reporting options the same way. These options are discussed at Basics/Using the Command Line Applications#Reporting Options.

Option Description
-v <BOOL>
--verbose <BOOL>
Switches to verbose output; default: false
--print-options <BOOL> Prints option values before processing; default: false
-? <BOOL>
--help <BOOL>
Prints this screen or selected topics; default: false
-V <BOOL>
--version <BOOL>
Prints the current version; default: false
-X <STRING>
--xml-validation <STRING>
Set schema validation scheme of XML inputs ("never", "local", "auto" or "always"); default: local
-W <BOOL>
--no-warnings <BOOL>
Disables output of warnings; default: false
--aggregate-warnings <INT> Aggregate warnings of the same type whenever more than INT occur; default: -1
-l <FILE>
--log <FILE>
Writes all messages to FILE (implies verbose)
--message-log <FILE> Writes all non-error messages to FILE (implies verbose)
--error-log <FILE> Writes all warnings and errors to FILE
--ignore-errors <BOOL> Continue on broken input; default: false

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.

Option Description
--random <BOOL> Initialises the random number generator with the current system time; default: false
--seed <INT> Initialises the random number generator with the given value; default: 23423

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.
