Hi All,
When we do model runs, it creates multiple transit route (RTE) files that are over 24GB in size, so for a full model run there will be over 60GB consumed just by RTE files, which creates storage problems for us. See the screenshot below (each RTE file refers to a specific time period in the model).
These large files result from a model that has ~365 transit lines and ~2300 zones. I feel like there must be a way to shrink the size of the RTE files? Is there anything I should check?
Thank you, and please feel free to send me any clarifying questions you have. I have also attached the Voyager script we use for model runs, so you can see how we make RTE files.
Cheers,
If it helps, a link to the script that we use is on GitHub - https://github.com/SACOG/SACSIM19/blob/main/model_scripts/model_run/RUN_sacsim19_wTolling_wTNC_AO13_BaseCap_wAdvT_wBaseline_v5.s
Hi Darren.
The reason why the RTE files are very big is related to the criteria that you set in the Factor Files for the route enumeration. Our suggestion is to use low spread levels, to have routes closer to the best path, for each specific user class. With the possibility to have multiple user classes with different factors affecting the path-building itself.
Numerical differences in the costs of different routes can be small, because the combinations within routes for a single OD in PT are several. Therefore using low level of spread avoids having too many routes between each OD.
Please have a look at my slide below.
