Re: [sumo-user] Using AADT Data To Determine Traffic Count In OSM Web Wi

[Brandon Cedric Patangan <bcpatangan@xxxxxxxxx>]

Hi again, sorry to send another message. I used Notepad ++ to run a text file named rscfg.txt where I typed in the same configuration as in the conference tutorial:

However when I try to run it using the "Run" Windows batch file, I get the following error: "Error: Could not access configuration 'osm.sumocfg'.

Quitting (on error)." which is the name of the OSM file. 

I also tried running it using "Build" but it only opened the command prompt very quickly and closed it.

Would anybody know what I'm doing wrong? Thanks so much!

Brandon

Hi Jakob,

Thank you so much, it's a very big help. I was able to follow the user tutorial up until the part where it talks about the rscfg file (around 37:46 in the tutorial), and was able to save my dataset with the road ID included for clarity:

I was not able to find a rscfg file in the SUMO files anywhere, and I didn't quite catch from the video what command was used to run routeSampler.py. My apologies if there's so many questions, I'm truly trying to learn this for the first time! 

Thank you so much,

Brandon

Counts can be defined visually for an existing network using netedit. See https://youtu.be/aiOQbaB-pWo

You can define count values per mode by defining multiple count attributes for each edge. Then run routeSampler.py multiple times with different values for option --edgedata-attribute and option --prefix.

Thank you Jakob. I apologize for asking once again, as I am very new to Python and not well-versed in scripting (I'm an Economics major), but suppose I wanted to use the AADT values in the simulation. I have the following road traffic info, as well as count values for those survey sites per mode:

Can I edit this directly on the imported OSM file from the Web Wizard, or do I have to manually create my own network? Also, am I able to specify count values per mode, and not just the total vehicle count? 

My last question is, how exactly would I accomplish this, should I decide to use it in an existing scenario. Will I need to input it in a command prompt? Thank you so much!

If you have more than one AADT value, I recommend making use of it to improve the random traffic.

To aggregated trip information by vehicle type (mode), the latest development version supports the tool tripinfoByType.py : https://sumo.dlr.de/docs/Tools/Output.html#tripinfobytypepy

You can either obtain this version tomorrow at https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_development_version or wait until the release of version 1.11.0 schedule for next week.

regards,

Jakob

Thank you Jakob. Upon further examination, I feel that the OSM web wizard's generator will be sufficient for the study as I do not have O-D count but just AADT data for the study area. 

Hope this doesn't clutter up this thread but I just thought I'd ask, is there a way to see individual values of "Average Trip Time Lost" for each mode? In SUMO GUI I can see the "Average Trip Time Lost" value for all modes, but I was hoping to see an individual value for bus, car, etc. to use in the study. Thanks!

Hello,

osmWebWizard defines randomTraffic and only uses a single "count" value per mode to scale the global amount up and down.

If you have count data for multiple locations, I recommend this: https://sumo.dlr.de/docs/Tools/Turns.html#routesamplerpy

(see also https://sumo.dlr.de/docs/Demand/Routes_from_Observation_Points.html)

Jakob

Good day!

I'm Brandon Patangan, an undergraduate Economics student at the University of The Philippines Los Banos. I'm currently working on a thesis that aims to simulate the possible effects of the construction of a proposed Public-Private Partnership bypass road on Travel Time Savings. 

I do have multi-modal Annual Average Daily Traffic (AADT) data for the study area (Coordinates 14.206762 121.251646 in OSM Web Wizard) and I was wondering if there was a way to use this data to determine the total vehicle hourly count in OSM Web Wizard? 

From what I understand in the document, the total vehicle count is computed based on count x edge length x lanes, and I was hoping to use the real-world AADT value instead. Thank you!

Brandon
