This code should help you quickly deploy your own version of a traffic monitor, with output as shown here.
Setup requirements:
-
Rename
constants.exampletoconstants.py, which has been added to the gitignore to prevent accidental leakage of secrets (best practice is to use an environment variable, but this will do). -
python3 -m venv .venvand thenpip3 install -r requirements.txt -
Do the following to complete
constants.py:
- Create a Google Cloud Platform (GCP) account, enable the Directions API, and add your API key in.
- Create a Telegram bot (visit @BotFather on Telegram) and add the bot's key.
- Create a Telegram channel, add the bot as an admin, and add the channel's ID (use @myidbot to get the ID).
- Change the chains and locations in
dep/stops.csvto monitor your own routes.
Deployment:
Not going to be too prescriptive, as most will have their own preference, but the live use case was deployed from a small VM running Ubuntu 22.04 LTS, using crontab. Nothing fancy.
This was the .sh script in ~/crons/traffic.sh (don't forget to chmod + x ~/crons/traffic.sh):
#!/bin/bash
# activate Python venv and run daily script
source ~/YOUR_GIT_FOLDER_PATH/.venv/bin/activate
cd ~/YOUR_GIT_FOLDER_PATH/
python3 cron_traffic_raya.py
And this was the crontab file (amend as desired to reduce/increase frequency, which will correlate to costs):
0-59/20 * * * * ~/crons/traffic.sh
