Analyzing Effectiveness of Remote Monitoring System for Road Safety Light

While driving on the road, traffic accidents occur frequently affected by various conditions such as road geometry, weather and nighttime. This study installed safety indicators in the danger zones where frequent traffic accidents occur and developed a remote monitoring system enabling automatic control at all times. The system is connected to wireless communication based on window OS and relayed in real time by remote control of the local controller and road traffic safety indicator, and the operational status of the system was analyzed using GIS technique. According to the results of analysis of the operational status of battery and solar cell in safety indicator installed in the field, it was found to operate well during normal condition but the performance was reduced by 10~20% during winter time due to the low temperature. In order to solve this problem, it is necessary to expand power generation capacity or reduce power consumption.
