Real-Time traffic state with Raspberry Pi in your car
This will help to see the state of roads, in live, just need to load your favorite (urban or not) traffic map.
I have found a nice screen on ebay for ~18€, a 3.2″ TFT LCD Touch Screen, cheap and small is ideal.
To use the touch screen, we run under a Raspbian distribution, you can download the image file here already configured to work with the XPT2046 LCD Control (most common 3.2 TFT found on ebay) . Extract the image file on a 2Gb mini SD Card, and run the setup config.
– Calibrate the screen
Go to Preferences, Calibration Touchscreen, follow the instructions.
