With the development of science and technology dynamic smart technology, we entered the era of intelligent, the emergence of various intelligent transportation equipment is also very excited, like new energy, autopilot, intelligent vehicle platforms and inter-vehicle communication. And in addition to this, another trend that comes with it is smart roads. Nowadays, many technologies are developing around energy conservation. Our roads are also escalating with the tide. Smart roads can not only use solar energy to charge cars, but also have built-in intelligent transportation systems.
Highway revolution for new solar energy materials to create intelligent transportation
When China is still building highways, asphalt roads with raw materials will become history in the United States and France, replacing them with “solar roadsâ€.
France lays 1,000 kilometers of "solar highway"
The Netherlands developed solar bicycle paths last year. Now, France has to become a global indicator of solar roads.
The French government has announced that it will build a solar road with a length of about 1,000 kilometers in the next five years. Its power generation capacity will provide about 5 million people's electricity, and in particular, it will be the source of funding for this solar road. , will be contributed by the French government to taxation of fossil fuels.
The Dutch government collaborated with private companies and academia to jointly build a solar-powered bicycle lane named "Sola Road" in 2014. The total length was 328 feet (approximately 100 meters). At that time, the Netherlands became the world's first solar panel. In countries where roads were laid and operations started in November 2014, the electricity generated exceeded expectations.
The French government is now following the footsteps of the Netherlands, and it is also going beyond the progress of the Netherlands.
The French government's policy is "Positive Energy" and its policy is to build a 1,000-kilometer-long solar road in the next five years. According to the French Agency for Environment and Energy Management, a 4 metre-long solar road can supply one home (excluding heating), while a 1 km-long solar road can supply 5,000 people with electricity, so the conversion As a result, Positive Solar’s ​​solar power roads can provide 5 million people with electricity, and these 5 million people account for about 8% of France’s current population.
Positive Energy will use "Wattway" solar photovoltaic technology. Wattway was announced by Colas, a French road engineering company, in October 2015. Colas and the French National Solar Energy Research Institute spent five years developing the solar panel. Connected to the existing road surface technology. Its solar panel thickness is only 7 millimeters and its width is 15 centimeters. Polycrystalline silicon solar panels are used to cover the surface of extremely fragile solar cells with multi-layered substrates made of resin and polymer.
In this way, the solar panel can be made to be firm, and the translucent translucent design allows the sunlight to pass smoothly into the solar cell.
Colas said that the solar panel's strong characteristics are sufficient to withstand the vertical pressure of all types of vehicles, including trucks, and the design of heavy skid can also reduce the occurrence of car accidents. In addition, Wattway solar panels passed the snow blower test, but Colas suggested that if the snow remover is operated on the solar panel, it must be more careful than on the general road.
However, can the life of this solar road be comparable to the general road? According to Colas, Wattway solar panels have a life expectancy similar to that of general roads, but depending on the traffic volume in the area, road life can reach about 20 years in areas with low traffic volume.
According to Ségolène Royal, Minister of Ecology, Sustainable Development and Energy of France, the funds of this Positive Energy plan will be provided from the increase in taxes on fossil fuels and it is expected to contribute about 200 million to 300 million euros in funds.
US Solar energy highway construction <br> <br> United States currently has more than 31,000 square miles of asphalt roads exposed to the sun, if these roads are covered with asphalt solar panels, then one mile of road can produce enough 80 Energy for home use. Not only that, laying solar panels on the road can power the LED road markings on both sides of the driveway, enabling the driver to be alerted when driving to certain critical roads, obviously more eye-catching than a traditional signage.
There will be more and more electric vehicles in the future, and if the installation of charging piles to meet the energy needs of electric vehicles is not only a huge project, but also extremely resource-consuming. Therefore, if the electromagnetic circuit is integrated into the solar energy road, it will be able to achieve inexhaustible power resources, so that electric vehicles can be charged at any time. At present, this technology has entered the stage of finding partners and will soon become a reality.
For intelligent highways, the intelligent transportation system is a very important component that can meet some of the challenges that will face traffic in the future, such as strengthening the communication between autonomous vehicles and reducing the occurrence of collision accidents. And if sensors and wireless communication devices are integrated in the road, the stability of the communication between the vehicle and the vehicle owner can be improved, and it is very positive to prevent traffic accidents and optimize traffic flow. In the future, on the smart highway, we can not only open faster but also be more secure.
According to experts, the development of solar energy roads was originally proposed by a green energy company called “Solar Way†in the United States. They are developing solar panels like floor tiles, which are small cubes with sides 30 centimeters long. The cost of each solar panel is 7,000 US dollars and can generate 7.6 degrees per day. The solar panels can be laid on city roads and sidewalks, or on the highways outside the suburbs. The wires are buried under the solar panels. After laying a block of solar panels, a high-strength polymer transparent plastic plate is laid on top.
The transparency of these plastic plates is high enough to let the sun shine on the solar panels. These plastic plates are very strong and not very smooth, which ensures that the car can be driven fast without slipping. On rainy days, special structures allow the rapid flow of rainwater without affecting the travel of cars and pedestrians.
In addition, some light-emitting diodes are installed in these roads, which can light road signs on cloudy days or nights. There are also some heating wires in the road, which are heated by solar energy in the cold weather to effectively prevent the road from freezing or snow.
The creative idea of ​​"Solar Way" originally came from a girl named Julie Brusaw. She loved fantasy and she suddenly had a big hole in the day of 2006. She was thinking that if she replaced all the more than 75,000 square kilometers of roads in the United States with solar photovoltaic panels, it would not only create a lot of electricity. Her husband Scott Brusaw, who was an engineer after listening to his wife's suggestion, was very inspired. After compiling various materials, he started his own R&D program. Soon after, a bite named “Solar Roadway†Edged tempered glass panels came out.
The Solar Roadway is paved with interlocking hexagonal tempered glass panels embedded with photovoltaic panels that can harness solar power. These panels are mainly laid on roads and parking lots.
There are several layers below each hexagonal tempered glass. From top to bottom are:
The first floor, the second layer of tempered glass, the third layer of the LED light indicator layer, the fourth layer of the circuit layer, the base layer made of recycled materials, the bottom layer of the base layer is the flood discharge and aquifer
The advantage of this design is that solar power is the first of its kind. Needless to say, in short, you know that as long as one-third of all roads in the United States are laid, it will be able to meet the electricity needs of the entire United States while significantly reducing carbon emissions. the amount.
Finally, we must say that this "floor" is revolutionary! Because there is super wear-resistant glass on each floor, each photovoltaic panel is equipped with LED lights, which will directly display traffic information and instructions on the road; imagine driving on a monitor that is not bad. With regard to rain and snow, the solar energy storage device can be heated to quickly melt the snow, but also worry about difficult to travel due to heavy snow?
It is reported that at present, the US Department of Transportation is planning to upgrade the "Mother's Road" Route 66 to a solar highway.
Summary <br> <br> With the development of driverless car technology, the future, unmanned road construction will also be a trend, the application of smart sensors, smart highways will make more intelligent. China's road construction enterprises must keep up with the development of the times, develop machinery and equipment that meet the needs of future road construction, and maximize the benefits of smart road construction.
