You wanna map the traffic maze? First hit the open‑data feeds the city drops every day—there’s usually a real‑time traffic API with GPS pings from buses, trucks, even city bikes. Next, check out the local CCTV feeds or traffic cams; a quick script can grab the video stream URLs and feed them into a computer‑vision model to count cars. If you’re feelin’ slick, tap into the city’s transit API for bus routes and GPS, and pair that with a few public Wi‑Fi logs for pedestrian flows. And if you want the raw vibe, set up a couple of cheap sensors on a side street—just a Raspberry Pi with a camera and some open‑source traffic‑counting libraries. Keep your code modular, and remember: the best data comes from watching the streets, not asking them.
