In addition, they also have features including automatic early warning, emergency stop, and autonomous obstacle avoidance.
With a total length of 108.59 km and a design speed of 120 km/h, the current reconstruction project will expand Maoming-Zhanjiang Expressway into two-way eight lanes. The Guanzhu-Linwu section is expected to open to traffic this year and the Linwu-Gaoyang section will start operation in 2023.
Upon completion, the expressway will inject strong impetus into the socio-economic development along the route, enhance the connectivity between Western Guangdong and the Pearl River Delta region, and give play to the leading role of the Guangdong-Hong Kong-Macao Greater Bay Area.
