Platforms and techniques are described in which a traffic event detection system includes a camera connected to a CPU in a vehicle. The camera is mounted on an extendable support, and captures images in front of the vehicle at a height generally above that of vehicles that may be ahead of the subject vehicle. The CPU can analyze those images for sudden change in traffic pattern based on a change in red color content of the image stream, and can warn the driver with an alert if the cars in front of him or her brake suddenly, or other traffic events occur. In implementations, short-term and long-term signal averages can be used to reduce false positive signals, and increase overall accuracy of traffic detection processing. In embodiments, the system can apply a timer to determine if potential hazards continue to be detected, and generated louder alarms or other graduated alerts.
