Intelligent Hazard alert system based on GPS system to avoid whistling sound

Recently, vehicles adopt the whistling system to attract other drivers' attention, however, whistling can cause great harm to the environment and human health. To eliminate the noise pollution, we have designed a new warning system-SVM. Due to the need of low-cost precise positioning in the three-dimensional space in SVM system, we have designed the Phase Difference Location (PDL) system, which combines the GPS system and the phase difference algorithm to achieve centimeter-level positioning. Thus, we have designed the Intelligent Hazard Pre-prediction (IHP) system, which combines the Vehicles Trajectory Prediction (VTP) algorithm with the Hazard Detection algorithm to determine whether the target vehicle should send the alert signals. The Hazard Pre-prediction (IHP) system, Phase Difference Location (PDL) system, wireless communication, and infrastructure components constitute the SVM system - vehicles' silent alert system.
