Simulation/GenericParameters

Generic parameters allow an arbitrary mapping of string keys to string values. They can be used for user-defined data storage but some key/value pairs also affect the simulation.

The following objects support the definition of custom parameters in their XML definitions:

• Edge
• Lane
• Person
• Vehicle
• VehicleType
• PoI
• Polygon
• Route
• TrafficLight

Parameters support the following functionality

• reading and writing via TraCI.
• customizing the functionality of actuated traffic lights
• configuring vehicle types for use with the electric vehicle model
• setting up devices on a per-vehicle basis

Parameters are always defined as child elements of the respective object:

   <vehicle id="v0" route="route0" depart="0">
       <param key="answer to everything" value="42"/>
   </vehicle>
