Re: [sumo-user] Detector ID for actuated TLS

[Sasan Amini <aminissn@xxxxxxxxx>]

Dear all,

sorry for pushing this question again, but I can't decode the detector
indexing logic. As soon as linkIndex are manually changed in NETEDIT,
E1 detectors of educated traffic signal do not follow the expected
indexing logic and sometimes are indexed for lanes from left to right,
and sometimes are just indexed 0 after the linkIndex.

Thank you for your support
Sasan

The first number is an edge index used inside the TL and the second is the lane index. The edge index is built from the lanes included in the TL control (every time a new edge is found in the order of lanes the index is incremented).
