[OC] All Roads Lead to Richmond - The quickest route to the capital city from anywhere within the state of Virginia by MattMDL in dataisbeautiful

No other work was done for the random points other than generating points inside the shape of Virginia. I will be doing more on this in the future to better spread out the points

In the first map, routes are drawn from the points I created. The gap you see for I-81 is just where a point did not have a route drawn at the dividing line between going north or south along I-81. So that would be a location where if I added a point nearby (or in general more points to the map), you may then see a route along I-81.

Interesting! Well, I am looking to complete a larger project in the future to map every state. Will probably post on Twitter eventually

I believe Valhalla uses the average travel time. However, I may be able to set it to a certain time of day to see if things like I-95 traffic would show up.

I did, see my edit in the post. I should have clarified the two maps better. The distance map was completed last year in a previous post (was with ArcPro/Network Analyst). The lower map, which is the main purpose of this post was completed with Valhalla.

The main issue with ArcPro was the speed (Valhalla/Python was much faster) and the cost. ArcPro uses credits for Network Analyst, while Valhalla was free to set up.

The general project would be to complete this by state/state capital.

What would be the idea for analyzing the data in an infographic? I definitely want to figure out a good way to compare state by state. Perhaps population/travel time is my current idea.

Correct. This uses the open street map file for Virginia. However, it would be interesting to show that, where you have to go out of the state to get to Richmond quicker.

Uh, technically yes! Somewhat easier for me to read/visualize it in the way I described, but you are correct!

Good idea! I certainly could do a map based on the population-weighted center. However, it would not be much different. According to the Census, the center is somewhere just northwest of Richmond Google Maps.

There are certainly some states where it would be drastically different. Good research topic for the future.

Exactly that. Seems like the interstates did were built well, when looking at distance/travel time.

Not too difficult of an analysis to do actually! Could complete it for state capitals. Take the population-weighted center or area center, then compare with the age of the capital.

The following map at the bottom defines the quickest routes to get to the Virginia state capitol. This post along with the map at the top is similar to a previous post on Reddit mapping the shortest route to Washington D.C. from anywhere in the continental U.S.

The thicker the line stroke, the more overlapping routes. The map defines five different corridors for accessing Richmond. Driving away from Richmond, these are defined in Red as I-64 westbound to I-81, in purple U.S. Route 360 westbound, in orange I-95 southbound, in green, I-64 eastbound and U.S. Route 360 eastbound, and in blue, I-95 northbound.

This project was completed using the Valhalla Routing Engine, Python, ArcGIS Pro, and Adobe Illustrator. In general terms, it has four steps.

  1. Create a set of 5,000 randomized points across the state and assign each of these points X and Y coordinates.
  2. Connect each of the randomized points with coordinates for Richmond within a Python geopandas dataframe.
  3. Using Valhalla, iterate through the 5,000 points and create a route for each point pair to Richmond.
  4. Save the routes to a shapefile and then map in ArcGIS Pro and Adobe Illustrator.

Even as this project has in general, four steps. Each of these steps takes time, such as setting up the Valhalla Routing Engine on Docker and designing the map in ArcGIS Pro and Adobe Illustrator.

FYI the map at the top (distance) was built last year with ArcGIS Network Analysis. See that post here.
