New technology: increased traffic and increased traffic efficiency in cars and traffic signals

- Feb 21, 2019-

Cars and traffic signals are talking to each other, leaving the driver (if any) aside.

    Top automakers, including Volkswagen, Honda, Ford and BMW, are experimenting with a technology that allows cars and traffic lights to communicate and work together to ease traffic congestion, reduce emissions and improve safety. Sex.

   In early October 2018, Volkswagen (VLKAF) and Siemens (SIEGY) collaborated to test an intelligent lighting system in Wolfsburg, Germany. The two companies have installed 10 traffic signal systems on a section of the road to transmit information about their optical phase.

    The idea is that the system will be able to tell the driver (or future autonomous car) when there will be a green light. The goal is to eventually make the system work with a range of cars and brands. Franz Schober of the Siemens Connected Mobile Systems team said: "BMW has a counter that can count down green at 5 - 4 - 3 - 2 - 1 second, while Mercedes says, 'If you drive at 32 - 52 km/h You will get green.'"

   Volkswagen will begin to equip the car with this technology next year. The network uses WiFi technology and sensor-generated location data is more accurate than the GPS positioning system used on smartphones. The system will help the car avoid unnecessary parking and start-up, reducing the amount of gas they emit. When the car is idling, it produces more exhaust gas than when it is driving. This technology also improves traffic by transmitting traffic information directly to the driver. Volkswagen and Siemens are using sensors at two of the intersections to detect pedestrians and cyclists.

   “(Sensor) processes this information, and then the traffic controller can send a message to everyone, telling them that there is a cyclist on the left,” Schober said.

    Other car manufacturers are also studying similar technologies.

    In early October, Honda demonstrated its "smart crossover" technology in a small town in Ohio. The Japanese company installed four cameras in every corner of a crossroad, providing 360-degree views of the surrounding cars and pedestrians. The data is then sent to a networked car and decoded by the computer on the car. The system will issue visual and audible warnings to the driver if necessary.

   Ford went further. Earlier this month, the company released a technology that allowed cars to communicate with each other as they passed through intersections. It is recommended that the driver change the speed when necessary to avoid a collision. The company said it was inspired by how pedestrians move through the crowd to avoid those crossing their roads, and added that it envisions technology that makes traffic lights obsolete in the future.
