Hello,
I’m assembling a reproducible research dataset aligned to a subset of the PEMSBAY 2017 speeds dataset, I wish to add data regarding construction, accidents, events, etc. to the dataset to permit better traiffic forecasting. The live Open511 endpoint returns current items (in_effect_on=now) but id does not seen to return any past dates, for example if I put in_effect_on and date in 2017 I get no results. My understanding from interactive with the endpoint is that perhaps archived data is not available. So I’m requesting a historical export of Traffic Events for 2017. 
Scope:
  • Time: 2017-01-01 to 2017-06-30
  • Area: District 4 / Bay Area (region-wide is fine). If you prefer a smaller box: bbox = −123.0, 36.9, −121.2, 38.6 (lon/lat).

CSV or JSON formats are both fine, a single zip archive will do if dates need separated for example. I will attribute to 511 SF Bay per your terms if the any results using the data are published. 

Thank you very much,

Hi Jason,

 

Thank you for your request. Our systems currently archive data for the past three years only, and unfortunately, we do not retain records from 2017. As a result, we’re unable to fulfill this request.

 

Please let us know if there's anything else we can assist you with or if more recent data would be helpful.

 

Regards,

Kapeel Daryani.
