Green Street Real-Time Traffic Data
Posted by Christian Donner under Community , Traffic and SafetyComments Off on Green Street Real-Time Traffic Data
A Doppler radar gun purchased on Ebay, 50 feet of Cat5 cable, a soldering iron, and a little bit of .Net programming skills were the ingredients for this low-cost (< $200) traffic data logging system. The radar detector works flawlessly, but if there is a cluster of cars going by the house, not every single car is detected, which means that the number of cars is underreported. I record the video streams of the security cameras to a network storage device and keep the data for 2 weeks. Correlating the video images from the web camera with the speed readings is a fun and interesting exercise ("who just flew down the street at almost 60 mph?"). Does this really work? See for yourself. Just refresh this page (by pressing F5, for instance) after you saw a car going by in the video above and the statistics below will be updated, including the count and most recent speed.
