Re: [sumo-user] e1 and e2 detector
|
Hello Ali,
the e1 detector has no length, I think you should use an e2 detector if
you want to have a detector that covers an area.
Regarding the functions: when do you call these? I'd expect -1 and ()
when no vehicles were on the detector during the last step. So at the
start of the simulation, you will most likely get those results. And
afterwards if there has been no traffic.
Greets, Menno
