Re: [sumo-user] output file of detector e1

[Daniel K. <d.k...@we...>]

Dear Daniel,

E1-detectors are reporting flow in vehicles/hour. This means that if you u=
se an aggregation over short time spans, 5 seconds for example, you will g=
et only 5 different values. Why=3F With an aggregation of 1 second, each tim=
e step a vehicle crossed the simulated induction loop, a flow of 3600 vehi=
cles/hour would be reported in all time steps where the inudction loop was=
 empty 0.
Aggregated this would mean for the case of aggregating over 5 seconds:

in 0 of 5 steps a vehicle was over the detector: flow=3D0veh/hour
in 1 of 5 steps a vehicle was over the detector: flow=3D720veh/hour
in 2 of 5 steps a vehicle was over the detector: flow=3D1440veh/hour
in 3 of 5 steps a vehicle was over the detector: flow=3D2160veh/hour
in 4 of 5 steps a vehicle was over the detector: flow=3D2880veh/hour
in 5 of 5 steps a vehicle was over the detector: flow=3D3600veh/hour

So you should use your aggregation wise or reaggregate it by yourself. BTW=
, of course there may be bugs. Please tell us if you find something.

bye,
Daniel
