From raising the driver's awareness of the flow of traffic, networked vehicle technology and road lighting will significantly affect the quality of transportation and the safety of drivers and pedestrians. Mr. Jay Sachetti, Senior marketing manager for the online community at Eaton Lighting, describes the status and future of automotive networking, as well as the role of road lighting.
What is networked automotive technology?
Networked automotive technology enables networked wireless communications between automotive, system infrastructure and personal communications equipment, with high security and interoperability. Some of the most advanced anti-collision technologies in cars now include car sensors, cameras and radar applications. These techniques will alert the driver to imminent danger, so that the driver will take corrective action or the system may even intervene on its own.
What is its working principle?
Vehicle to Car (WebPart) communication is another step to help remind drivers of the dangers. WebPart Communication uses a vehicle-specific short-range radio communication device to transmit and receive information such as the speed, direction, and braking status of the vehicle. Range and line-of-sight ability will exceed the current system, in some cases even reach nearly twice the range. This long-distance test, and the ability to observe corners or surroundings through other vehicles, helps vehicles equipped with WebPart communications to detect certain threats earlier and to remind drivers accordingly.
Networked car technology also allows cars to exchange infrastructure information (such as traffic signals or road lighting) via V2I communications (car infrastructure). In addition to providing security advantages to networked vehicles, V2i communications provides mobility. The standardization of this kind of vehicle data will be used in the future for road lighting and traffic lights real adaptive control system.
Federal and local government officials are now trying to implement networking. The Michigan Department of Transportation (DOT) is testing its first networked workspace on a I-75 road in southern Detroit. The Michigan Department of Transportation (DOT) wants to be able to alert drivers to information that includes whether a worker is present, what type of work is being done, and when. The U.S. Department of Transportation is also testing the technology in three places, such as New York, Tampa and Wyoming State.
How will the networked lighting technology continue to change our path?
Traffic lights, road signs and even construction site reminders will soon be part of a networked ecosystem that provides and receives information that makes driving smoother.
All traffic lights are timed differently. The driver sometimes does not understand whether can pass the yellow light before dredging the traffic, or turn the signal to be activated etc. But when traffic lights communicate with cars, drivers can make safer decisions.
"V2i will really play the role of sensing technology lighting," says Sachetti. Road lights are generally 30 meters to 90 meters apart, the installation height is generally 6 meters to 12 meters. This provides a vantage point for all aspects, from intersections to hilly areas, thus facilitating continuous v2i communications. ”
Vehicle data points, including speed, position, ambient illumination level and road friction, as well as humidity, temperature and road reflectivity, will be imported into the electrical lighting and Management system (ELMS). ELMS will dynamically adjust or adaptively control the level of illumination on the road. Sachetti said: "These data points can ensure the safety of pedestrians and drivers, reminding drivers of red lights and even animals crossing the street." ”
The National Highway Traffic Safety Administration (NHTSA) predicts that through WebPart and v2i, more than 80% of all non-damaged car crashes, including intersections or lane-changing accidents, can be eliminated or mitigated. The networking lighting technology will play a major role in the future.
