A Canadian-American Data Adventure

Tomorrow is the big day! The featured post image above is a map of my 4,173 mile route from Edmonton, Canada to Hoover, Alabama riding in two Canadian provinces, and 14 American states.

The goal is 1) adventure and 2) data … so I am calling this my Canadian-American Data Adventure. I am raising funds for https://peopleforbikes.org as they are a great organization helping improve the cycling infrastructure here in the USA.

Lateral Passing Data

I have been collecting vehicle data on https://mybiketraffic.com for many years now. I have traffic volume and speed data from rides from all over the world (98 countries). But I do not have any lateral passing data, which is a new feature I plan to add later this summer. Check out all my existing data here:

The primary data I will be collecting is lateral passing data from vehicles as they pass me on the ride. I will post a detailed analysis of all the data from this one ride along with an explanation of my setup. But as a TLDR, I wrote an iOS app that connects directly to the Garmin Varia radar. When a car gets within a few meters of passing, the iOS app starts snapping images and LiDAR depth maps at 4 frames per second. This is usually good enough to get three frames and depth maps of a car as it passes. A picture of my setup is shown below.

Photo overlaid with analyzed LiDAR depth map. The top number is the lateral distance in meters for the detected object. The middle and bottom numbers are attempts to correct for distortion. This may not be necessary as the phone itself already corrects for lens distortion. The question is how much correction is done in the middle of the photo. I am still researching this question before I start publishing results from all the data I have collected. Also, IMPORTANT, the distance number shown in the middle is the radar distance and speed detected by the radar as the vehicle approaches.

Live Tracking

I am so excited about this trip. I will be posting about a million pictures every day (slight exaggeration) to this website where you can not only see the pictures but see my progress. A small stopwatch clock will appear every time my satellite tracker uploads my location (approximately once every 10 minutes). You can click “pickuta.com” in the top left to see a list of my other adventures to see pictures and what the tracking looks like.
