[Talk-us] ARNOLD highway data

Things must seem very confusing on what stuff means. HPMS was developed from an engineering perspective and speaks in a language that only Civil Engineers understand. I will be happy to help you through video chats, webinar or other medium.

I should also mention that I am about to post the 2013 version. HPMS deals with annual submittals by State DOTs. We want to transition the system to a more transactional way of life in the future  but we are fighting tradition every step of the way.

Thanks for sharing. I pulled the data for Washington State. Looking at the data suggests we need to get better definition of the fields. There are a number of fields that appear interesting but I have no clue as to what they mean. Some interesting examples, Toll_Type, HOV Type, Truck_VN, and Route_Sign. A search of the HPMS Field Manual found more information that I could ever want! It tooks some search just to figure out that AADT (traffic counts I think) isn't something that we tag.

The routes information is very interesting. It would be interesting to compare to our route relations.

I would suggest that we invite someone from US DOT to join us on a video chat to help us better understand the ARNOLD database. From there we might look at where we could use the data as a cross check. For example, lane count.

FYI - For those inclined, I'd suggest just pulling 2012. It appears that 2011 is just an older version of 2012.

The emerging ARNOLD national highway database by the US DOT is possibly interesting for people here. It does contain OSM relevant data. This blog post goes back to Thomas Roff from DOT reaching out to OSM US to explore areas of mutual benefit. The directions Martijn and I discussed with him were

a) listening to OSM changes to help improve the ARNOLD dataset (with or without a previous import of ARNOLD data) - a little bit like this is set up for NYC http://www.openstreetmap.org/user/lxbarth/diary/23588
b) using OSM software for data management

Martijn, Thomas - please add where I missed something.

Both are blue sky ideas and wouldn't be executed by OpenStreetMap US as this is not our place.

I'm sharing this here for everybody's consideration and comments.


Cheers -
