Platforms and techniques are described in which a traffic event detection system includes a sensor (101) such as a camera connected to a central processor unit (CPU) (103), and a video display with sound speaker also connected to the CPU. The camera is mounted outside the vehicle (51) on an extendable and/or rotatable support (52), and captures images of traffic in front of the vehicle at a height generally above that of vehicles that may be ahead of the vehicle mounted with the detection system. The CPU can feed all of the images to the video display inside the vehicle visible to the driver. The CPU also analyses those images for sudden change in traffic pattern based on spectral content of the image stream, and can warn the driver with an audible sound if the cars in front of him or her break suddenly, or other traffic events occur. |
