TraCI/Induction Loop Value Retrieval
Induction Loop Value Retrieval
Command 0xa0: Get Induction Loop Variable (ubyte Variable, string InductionLoopID)
Asks for the value of a certain variable of the named induction loop (e1 detector). The value returned is the state of the asked variable/value within the last simulation step. Please note that for asking values from your induction loops with TraCI, you have to:
- define them
- set their frequency to 1s
The following variable values can be retrieved, the type of the return value is also shown in the table.
|id list (0x00)||string*||Returns a list of ids of all known induction loops within the scenario (the given Induction Loop ID is ignored)|
|last step vehicle number (0x10)||integer||Returns the number of vehicles that were on the named induction loop within the last simulation step [#];|
|last step mean speed (0x11)||float||Returns the mean speed of vehicles that were on the named induction loop within the last simulation step [m/s]|
|last step vehicle ids (0x12)||string*||Returns the list of ids of vehicles that were on the named induction loop in the last simulation step|
Response 0xb0: Induction Loop Variable (ubyte Variable, string InductionLoopID, ubyte ValueType, ValueType Value)
