From 30.000 feet#
activitygen reads the definition of a population matching an also given network. It computes and mobility wishes for this population.
- Purpose: Demand generation for a synthetic population
- System: portable (Linux/Windows is tested); runs on command line
-
Input (mandatory):
A) a road network as generated via netconvert or netgenerate, see Building Networks
B) a population definition, see Activity-based Demand Generation
- Output: Definition of Vehicles, Vehicle Types, and Routes usable by sumo
- Programming Language: C++
Usage Description#
A step by step description for using activitygen can be found here
Options#
You may use a XML schema definition file for setting up a activitygen configuration: activitygenConfiguration.xsd.
Configuration#
All applications of the SUMO-suite handle configuration options the same way. These options are discussed at Basics/Using the Command Line Applications#Configuration Files.
| Option | Description |
|---|---|
| -c <FILE> --configuration-file <FILE> |
Loads the named config on startup |
| -C <FILE> --save-configuration <FILE> |
Saves current configuration into FILE |
| --save-configuration.relative <BOOL> | Enforce relative paths when saving the configuration; default: false |
| --save-template <FILE> | Saves a configuration template (empty) into FILE |
| --save-schema <FILE> | Saves the configuration schema into FILE |
| --save-commented <BOOL> | Adds comments to saved template, configuration, or schema; default: false |
Input#
| Option | Description |
|---|---|
| -n <FILE> --net-file <FILE> |
Use FILE as SUMO-network to create trips for |

Loads the SUMO-statistics FILE |
Output#

| --output.format <STRING> | Defines the standard output format if not derivable from the file name ('xml', 'csv', 'parquet'); default: xml |
| --output.column-header <STRING> | How to derive column headers from attribute names ('none', 'tag', 'auto', 'plain'); default: tag |
| --output.column-separator <STRING> | Separator in CSV output; default: ; |
| -H <BOOL> --human-readable-time <BOOL> |
Write time values as hour:minute:second or day:hour:minute:second rather than seconds; default: false |
| -o <FILE> --output-file <FILE> |
Write generated trips to FILE |
Time#
| Option | Description |
|---|---|
| -b <INT> --begin <INT> |
Sets the time of beginning of the simulation during the first day (in seconds); default: 0 |
| -e <INT> --end <INT> |
Sets the time of ending of the simulation during the last day (in seconds); default: 0 |
| --duration-d <INT> | Sets the duration of the simulation in days; default: 1 |
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.
