The Early Warning System of the Curve Signal Real-time Monitoring Designed for the Oncoming Cars

摘要

Taking the initiative to remind driver's attention when they are crossing the curve as the research object, this research puts forward the design scheme of early warning system for curves. Through the installation of video surveillance and speed measuring devices at both ends of the curve, the driver's sight distance and the speed of the vehicle will be monitored. The equipments are installed in the places about 50 meters ahead of the corner, when the oncoming cars go into the monitoring range, the yellow lights light up or the display screen prompts "Oncoming car" on the opposite direction; when the cars are speeding, the yellow lights in same lane light up or the display screen prompts "Speeding", if no speeding and no car coming from the opposite direction, the green lights brighten or the display screen prompts "Drive cautiously". These signals send timely feedback to the drivers to help them make accurate and timely response, take actions and avoid traffic accidents. This paper selects and designs the information collection and relevant parameters of the early warning system, installation technology, in order to ensure its normal operation.
