Evaluation of Performance of Solar Powered Flashing Beacons

Use of solar powered flashing beacons on state highway system is increasing. The beacons feasibility, reliability, and performance have improved with the advancement in technology, including the use of LED modules. However, the duration of time the beacons can function depends on the battery type used, environment it is operating at, and the flashing mode used. The flashing mode and visibility of the beacon change as the battery charge level decreases. Furthermore, the environmental conditions (temperature, cloud, etc.) affect on the battery charge level and thus its flashing mode and visibility. This research will determine the performance of the flashing beacons in a variety of lighting conditions, modes of flashing operation, and its compliance with the requirements.
