Case Study Introduction: Preventing Wrong-Way Accidents in Advance with Microwaves BFS01

A sensor that supports decision-making mistakes at the crossroads of confusion.

In Japan, wrong-way driving accidents remain a significant safety issue on highways. Every year, a certain number of incidents related to wrong-way driving occur, and the fact that they are prone to lead to serious accidents, such as head-on collisions, is problematic. The proportion of elderly drivers involved in wrong-way driving is high, and misjudgments, overlooking signs, and assumptions are considered the main factors. Locations where wrong-way driving is likely to occur include interchanges, toll booths, and entrances and exits of service areas and parking areas, where the proximity of entrances and exits makes the structure difficult to understand. There are also cases where drivers attempt to return after passing an exit on the main road, leading to wrong-way driving, making early detection of abnormalities crucial. In response to these issues, measures utilizing sensor technology have been advancing in recent years. The microwave safety monitoring sensor "BFS01" can detect distance and speed using microwaves, allowing for stable monitoring even at night or in bad weather. By detecting wrong-way vehicles early and linking them to warnings and control coordination, it contributes to the prevention of serious accidents and the overall improvement of road safety.
