Traffic accident heatmap reflecting accidents reported by the Missouri State Highway Patrol.
https://DangerCrossing.com
UPDATE (12 Sep 2023): The MSHP has placed their accident information database behind a captcha, making it unfeasible for Danger Crossing to continue accessing new data. As a result, the project will no longer be updated with fresh accident information post-12 Sep 2023. However, the website will remain operational, featuring historical data collected up until this date.
Table of Contents
The Missouri State Highway Patrol (MSHP) publishes their accidents reports online. Most of these reports contain the longitude and latitude coordinates of the accident. This project gathers accident information from the MSHP's website and displays it on an interactive heatmap which can be viewed in the user's browser.
The project is comprised of several Docker containers which serve distinct purposes. Docker Compose is used to coordinate these containers into a single application.
The project is comprised of five separate Docker containers which serve distinct purposes. Docker Compose coordinates these containers into a single application.
The Flask application responsible for rendering the heatmap and governing the user's interactions with it. In development builds, also acts as the web server.
A crontab which runs the danger_maker.py script at some predetermined interval (currently set to once every 3 hours). The danger_maker.py script is responsible for gathering and saving new accidents from the MSHP's website.
A caching server to store and retrieve the dictionary of accident information.
The web server used in production builds.
An OpenLayers OSM PNG tile server built using Overv's openstreetmap-tile-server Docker project. Relies on the missouri_et_al.osm.pbf extract file provided by Protomaps.
