Bike Lanes in Chattanooga

Jul 21, 2023 | GIS, Open Street Map, QGIS

I was sitting around thinking there other day that I’ve been doing OpenStreetMap “things” for way too long. With one volunteer job going dormant I decided to re-visit something I had worked on 12 years ago.

I had met up with some OSM folk here in town around 2010 and we did something weird and wild – we mapped “bike lanes” in town. I don’t think there were any at that point. Basically we wanted to know who was riding bikes where and we shoved that information into OpenStreetMap with the goal of doing a “tri-modal” application where you could walk, ride a bike, or ride a bus. We actually made something that went no where and that was that.

Probably out of that we had the makings of a “bike infrastructure”. Maybe there was a plan already in place but regardless we modified a lot of data in OSM with the “CHA:bicycle=designated” Key:Value. In 2023 Bike Lanes are exploding in town. I can’t really find a good map of the lanes. I know maps exists somewhere in the city but…..I don’t have it. Meanwhile I see more of this:

There is this map circa 2018:

So Far I have this:

This was done by a lot of walking/driving/some bike riding and existing data. I’m down now to going out and tracking down routes and connecting them because I know the lanes aren’t this disconnected. I also don’t completely believe the lanes I have. The ultimate goal is to have some sort of legitimate bike lane map in OSM so anyone can use it.

Once all this gets entered into OSM – I’m using QuickOSM and a query to pull it all down.

THE PLAN.....there was a plan. Oh yes - the plan is to make editing and creating data in TN for the 911 addressing system to be as easy as possible. Menus and Triggers abound and now as two counties are using this with a third on the horizon - HOW do I make this...

Not that this is new - Mergin has been doing this for a bit BUT I finally had the chance to sit down and use it. I have a client taking pics of houses to feed into the 911 dispatch system. Granted - not easy, not fun, and not his idea but he walked into this and has...
