Honda Motor Co., Ltd. has developed what it claims it the first technology to detect the potential for traffic congestion and determine whether the driving pattern of the vehicle is likely to create traffic jams. Honda developed this technology while recognizing that the acceleration and deceleration behavior of one vehicle influences the traffic pattern of trailing vehicles and can trigger the traffic congestion.
In conjunction with the Research Center for Advanced Science and Technology at the University of Tokyo, Honda conducted experimental testing of a system utilizing the technology to detect the potential for traffic congestion. The test results demonstrated that the system helped increase the average speed by approximately 23% and improved fuel efficiency by approximately 8% of trailing vehicles.
With the goal to bring this technology to market, Honda will begin the first public-road testing of the technology in Italy and Indonesia in May and July of this year, respectively, to verify the effectiveness of the technology in minimizing vehicle congestion.
Rather than providing information to help the driver avoid existing congestion based on current traffic information, the system monitors the acceleration and deceleration patterns of the vehicle to determine whether the driver's driving pattern is likely to create traffic congestion.
Based on this determination, the system provides the driver with appropriate information, including a color-coded display through the on-board terminal, to encourage smooth driving which will help alleviate the intensity of acceleration and deceleration by trailing vehicles, thereby helping to prevent or minimize the occurrence of vehicle congestion.
Moreover, the positive effect on minimizing congestion and fuel efficiency improvement can be further increased by connecting the on-board terminals to cloud servers to make the driver aware of and in sync with the driving patterns of vehicles ahead by activating the ACC (Adaptive Cruise Control) system at the right time to maintain a constant distance between vehicles at the most appropriate interval. Using cloud servers and ACC can yield an additional 16% increase in the average speed of trailing vehicle and an additional 5% improvement in fuel efficiency, Honda said.
ACC monitors vehicle speed and inter-vehicle distance using a millimeter-wave radar mounted in the front grill, which scans the road for other vehicles and calculates the distance from the vehicle directly in front. The system maintains the selected speed and distance (as designated by the driver) based on data supplied by the radar.
Traffic congestion causes not only a delay in arrival time but also an increase in CO2 emissions and a higher potential for rear-end collisions.
