Abstract
Crossing obstacle detection devices have been installed in the conventional railroad transportation in order to detect the objects which interrupt the railroad operation. These devices, however, have some problems, such as the difficulty in detecting people and wheelchair, and false detection due to the weather conditions. As a solution to these problems, we have developed an obstacle detection device to detect and protect people by using millimeter wave. We conducted verification test on the prototype device under the real environment of the crossing, and we report that we could confirm the feasibility of the product development by our findings of effects of weather condition and detection of correct or false.
