5G technology's low latency and fast data transfer can help improve IoV functions and hike traffic safety, according to Wu Kun-rong, vice president for Data Communications Business Group at Chunghwa Telecom (CHT).
4G enables communications between cars, or between vehicles and infrastructures, as well as in-car informatics, Wu said at a 5G smart city seminar held by HwaCom Systems. Along with increasing installation of various automotive sensors and roadside sensing infrastructures, 5G enables real-time multi-point communications between cars and between cars and roadside sensors.
Wu said 5G-based traffic monitoring can be used to adjust traffic lights for preventive control.
CHT has undertaken smart transportation projects in cities in Taiwan, using image recognition to collect urban traffic data in combination with data collected via smartphones to estimate traffic flows.
