A Method for Detecting and Alerting the Presence of a Reverse Running Vehicle
Many researches have recently been paying attention to designing safe driving support systems based on V2X (vehicle to X) technologies. A vehicle can share various information with other vehicles through wireless connections. These days increasing number of accidents caused by reverse running cars become a serious problem. While the accidents occur on both expressways and general roads, some preventing mechanisms against the problem are progressing in expressways. In the case of general road, however, drivers who are on the one-way road have no way to recognize the existence of any reverse running cars until they can visually confirm the existence. If they don’t assume the existence, the possibility of accident become high when a reverse running car actually exists. In this paper, we propose a method to solve the problem. It automatically detects a road type (one-way road or not) by analyzing current location, checking the existence of a reverse running car by wirelessly communicating with surrounding cars if the road is one-way, and alerting the driver of the results with text and sound. We design and prototype a system and verify the effectiveness of the proposed method through experiments.
