Re: [sumo-user] Import the traffic data of Detector E3

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

- dfrouter does not support e3Detector. Also, the counts for all lanes of an edge are simply added.

If you have edge-based data, it is enough to define one e1Detector per edge on an arbitrary lane and use this for your counting data

- for alternative tools to import counting data, see https://sumo.dlr.de/docs/Demand/Routes_from_Observation_Points.html#introduction

regards,

Jakob

Hi All,

I'm Jackie. 

I want to use the traffic data for my simulation, the data is edge-based instead of lane-based, 

so I use detector E3 instead of E2 in my net file, 400 detectors at totaol.

Firstly, I want to assgin detector type (sink,source, between) for each detector.

So I used the net file and detector file, with the command below:

dfrouter --net-file osm05.net.xml --detector-files detectors.xml --detector-output detoutput.xml

The output is:

pj_obj_create: Cannot find proj.db
pj_obj_create: Cannot find proj.db
pj_obj_create: Cannot find proj.db
Warning: Skipping isolated junction '1070588233'.
Warning: Skipping isolated junction '1271106603'.
Warning: Skipping isolated junction '243893033'.
Warning: Skipping isolated junction '31253494'.
Error: No detectors found.
Quitting (on error).

What's the reason for "no detectors found"?

What's the right definiation format for the E3 detectors? 

By the way, I want to know how to import the E3 detector traffic data in SUMO?

Thanks a lot.
