Development of an Automatic Detection and Alarm System of Traffic Control for Drivers Using Real-time Analysis of Pictures on Cellular Phone Handsets

Since Smart Phone (iPhone, Android etc.) use has been becoming widespread recently in Japan, and as these devices are recognized as being high-function information processors, they are also available as information provision devices. The authors developed a safe-driving support system (application), named “Highway Safety”, targeting the use of smart phones as devices for collecting and providing information, in order to enhance the safety of road users driving in winter on expressway. Specifically, utilizing image recognition technology to provide advance aural alerts of hazardous places, the authors have developed a system having the following four functions. First, in a function for traffic control alerts, an alarm (message) is transmitted when a vehicle approaches a traffic lane regulation zone, warning the driver that the vehicle is approaching the traffic lane regulation zone or the tail of a traffic congestion. (Warning signs, arrow boards, or rubber cones are automatically detected in real time using image processing.) Second, in a function for requesting safe driving and providing drifting alerts, a caution is issued urging “safe driving” in compliance with expressway regulations, and an alert is issued to prevent accidents in cases where drifting or lane departure is detected automatically. (The white line on the road is detected automatically using image processing.) Third, an alert transmitting function is provided to prevent crashes by measuring the distance from the car ahead. Finally, a warning function is provided regarding accident black spots, developed utilizing the GPS information in a smart phone. A function for providing aural warnings has also been developed utilizing a preset database of accident black spots (near-miss incident points) in winter, obtained from accident statistics and so on. The results of item-by-item field evaluations of the above-mentioned functions and the effectiveness and limitations of this system on expressways are described.
