The article discusses 15 experimental road infrastructures that have been implemented to improve traffic flow, safety, and sustainability. These infrastructures include smart traffic signals, interactive road markings, variable speed limits, and green infrastructure. The aim of these experimental projects is to test new technologies and designs that can potentially revolutionize the way roads are designed and used in the future. Some of the projects focus on reducing congestion and emissions, while others focus on improving the overall driving experience for motorists.

These experimental road infrastructures are being tested in various cities around the world to see how they perform in real-world conditions. Overall, the goal is to create a more efficient and environmentally friendly road network that can accommodate the growing number of vehicles on the road. By implementing these innovative solutions, cities can become more sustainable and enjoyable places to live.
