Back in 1852, Paris witnessed a groundbreaking innovation that changed human communication forever. It was the construction of a road connecting Paris and Perpignan using flexible tar mined from the Val de Travers deposits in Switzerland. Until then, no real progress had been made since the Roman design. The method was later improved by rolling sheet asphalt over concrete, a technique first tested in the French capital in 1858. He further noted that in 1900, a hot bituminous mixture was used to cover the Louvre and Victoria streets. in Paris. Nevertheless, for a century road innovation It will slow you down drastically. Vehicles continued to improve in performance, power and reliability, but the tarmac remained largely unchanged.finally in 21cent We are facing a giant leap this century. smart road.in the recent solar road, This time we discuss technology that allows roads to detect potholes and other hazards on their own. The system, called “ePave” by its inventors, was recently published in the Swiss scientific journal “Sensors”.
The project was jointly developed by computational experts from the University of Buffalo and Chang’an University in China. wireless network A self-powered sensor that provides real-time information about road conditions. Thus, traffic planners and connected vehicles will always have information about temperature, humidity and pressure on the tarmac.
Unlike other battery and solar-based technologies, ePave developers piezoelectricity Provides power to the system’s sensors. In this way, the embedded sensor draws power from the mechanical stress the vehicle exerts on the road.
“The highway sensor that detects this pothole is powered by traffic moving over it.”
The size of the keychain allows the ePave sensors to be placed up to 500 feet apart, while the repeater needs to be within 1000 feet.
of technology It’s still in its early stages, but researchers believe the module could stay operational for five to 20 years. We hope to soon have a new ally that will improve safety on the road.
Smart roads save lives
We are now in an era where a wide variety of technologies intersect and expand infinite possibilities. unmanned vehicle, Internet of Things (IoT) and 5G mobile data connectioncan connect millions of devices with extremely low latency, enabling projects like the one backed by the Colorado Department of Transportation. The technology is aimed at detecting an accident after it has occurred, rather than preventing it. To achieve this, Concrete slab with built-in Wi-Fi sensor and pressure detection Fiber optic cables are laid.
The pilot project, which will run over the next five years along a 0.5-mile section of Highway 285 southwest of Denver, will test the feasibility of a system that detects vehicles suddenly straying from the sidewalk.of smart road It then alerts emergency services and other incoming vehicles to the accident. A similar system is currently in operation, but drivers must submit the information themselves.
The main problem with the Colorado project is cost. The company behind the project, Integrated Roadways, estimates that it will require an investment of $4 million per mile and lane. But whether or not this system succeeds, there is no doubt that the road network will undergo major changes in the years to come.
