摘要：

When a something occurs that could hinder a train passing a level crossing, obstruction warning signals are turned on to show that trains must stop. At present, this system relies on the driver’s visual observation. This research aims to make this system more reliable and secure. This paper proposes a method to detect blinking obstruction warning signals and describes evaluation tests that were performed. Evaluation test results showed that these blinking signals could be detected with a detection rate of about 90 percent at a distance 600 meters under running conditions. © 2021 Ken-yusha Inc..
