| Re: [sumo-user] Calibration using observed counts |
Good morning,
SUMO developers should have more robust guidance than I will provide.
In cases where I have count data at intersections or cross-se ctions, I first use routesampler.py to obtain the flow on the routes and then use route2od to obtain the matrix. With this matrix obtained, you can use duaroter or duaiterate to generate OD2trips. In this way, there is a tendency for the matrix obtained to already be compatible with the traffic data.
To start routesampler you can get starting routes through: randontrips, findallrotes, etc.
Sds,

Hello,_______________________________________________I have an O-D matrix which I used to create a trip file using od2trips. Now I would like to generate routes such that they match observed real data collected from sensors. The data is collected every 15 minutes and it contains the count and the speed. Sensors don't cover all the edges in the simulation area.I also want to keep the counts from the OD matrix, (i.e. if there are 10 trips in the area based on the O-D matrix, and we have 2 possible routes, and a sensor covering one of them that reads 3 from real world observations, then the other route will receive 7 trips)Is there any tool or script in sumo that can do this? and how can I use it?Thanks,Rehab
