Docket: UAH-P-18018

Technology

Continuous traffic monitoring on highways is essential to maintaining the safety of road transportation systems. Current hand-held or fixed-mount radar devices are limited to providing speed monitoring information for isolated and localized traffic. The implementation of reflective road markers with integrated solar cells on them could provide a more effective system for recording speed and volume of traffic over a long distance.


Researchers at UAH have developed an integrated electronic sensor system for measuring real-time traffic volume and individual car speed on the highway. This will be achieved through the solar cell’s shading response as cars pass the road markers. This solution provides an alternative to current radar devices that is low-cost, automated, real-time, and self-powered. This proposal does not require any significant modification to existing infrastructure and can be easily adapted and distributed all over the USA.


The proposed efforts will provide a long-distance traffic monitoring system as well as a unique sensor platform for measuring hazardous road conditions. With the ability to be adapted in a cost-effective manner, this application has a large advantage over current radar devices that have limited ability over long distances, due to numerous installation and maintenance costs. This system can provide a paradigm shift in vital traffic monitoring and highway safety.
