Problems with detectors (trac #881) #881

Closed behrisch closed 6 years ago

behrisch commented 11 years ago

some vehicles do not register when leaving the detector (skewing the results) while other vehicles are registered leaving twice (causing warnings about leaving without entering)

I've seen the problem with entryExitDetector but it is probably related to moveReminders and thus affects all detectors.

some vehicles simply wait very long at the junction and are registered as leaving eventually

@namdre commented:

the vehicles recorded as leaving twice perform a lane change prior to their detection. It seems that the move reminders from both lanes trigger the leave event.

fixed in 14831a7 (aka r13622)

a problem where inductionLoops and instantInductionLoops failed to detect vehicles was fixed in 38c8e88 (aka r13657).
