The roads of the future could harvest energy from cars to power the streetlights

Roads of the future could collect energy from cars to power street lights, detect speeding or erratic driving and automatically weigh vehicles as they go.

An international team of US researchers. The US, Taiwan and Spain have created a list of ten technological advances that could appear on future roads.

They examined technologies that are already being developed, such as freight lanes in Sweden and local networks that automatically warn cars of upcoming dangers.

Roads are no longer simply a physical entity or solid ground, but a place for communication, detection and power generation, the team says.

Several countries around the world, including China and Japan, are working to create smart urban spaces, including smart roads

Other uses they considered included gathering sunlight, playing music to warn about hazards and feeding fleets of heavy-duty electric vehicles. ‘

“This review shows that they are not only theoretical, but are currently being implemented worldwide,” says lead author Chai Toh.

‘These advances will help in the progress, development and realization of smart transport for future smart cities.

WHAT ARE THE TEN SMART ROAD TECHNOLOGIES?

The document analyzes ten advances and developments in the area of ​​smart roads.

Include

  1. Energy Collection Paths
  2. Musical paths
  3. Automatic weighing path
  4. Electrified roads
  5. Roads with wireless traffic signals
  6. Automatic detection of traffic violations
  7. Roads that talk with vehicles.
  8. Roads with intelligent intersections
  9. Emergency fast rescue roads
  10. Paths with smart street lamps

‘Future roads will become intelligent, without signals, more secure and communicative. Not only will they support the mobility of people and things, but they will also generate electricity and return energy to the power grid. ”

There will be more progress in the future as new technologies emerge, but Toh says that this is a list of the most likely technologies to develop in the near future.

The list of ten technologies includes those that are already in development or in the planning stage.

That includes movements to power London’s streetlights with energy used by cars on the road.

“Ultimately, smart cities will progress towards the goal of achieving near-zero mortality and CO2 emissions, transforming our lives for the better,” said Toh.

Not only London and Sweden work on smart roads, or even entire smart cities.

Several countries around the world, including China and Japan, are working to create smart spaces.

Only China has more than 300 smart city projects, with a strong participation of industries and government offices.

India is also investing heavily to build more than 100 smart cities across the country.

“Technologies have continued to impact society over the years, improving our standard of living and quality of life,” said Toh.

“Advances in telecommunications, Internet of things, cloud and edge computing, scalable storage and data analysis have made rapid computing, data-driven information, connected mobility and communications at any time possible. “

With the additional capacity of a fusion of emerging technologies, many countries have now presented national projects related to smart cities to transform lives, improve business operations and market competitiveness, he said.

A key component of a smart city is transportation, and as companies focus on smart, driverless vehicles, Toh and his team examine the surfaces on which they drive.

Current traffic problems facing today’s society include James, pollution, fuel costs, insurance costs and fuel shortages, according to the team behind the study.

The increase in population in cities and the number of cars, bicycles, motorcycles and road users have increased the risk of accidents and traffic congestion.

Several transport-related technologies have evolved since the mid-1990s, covering a spectrum of areas from communication to energy.

“In the future of smart transportation it is about smart roads and signs,” said Toh.

‘In fact, we are entering the era where the information highway meets the transport highway.

‘The roads will be’ enabled ‘with information communications, intelligence and detection capabilities that were never possible decades ago.’

Smart roads will be an indispensable part of smart transportation for future smart cities, the team said in its report.

“Over a period of more than two decades, we have witnessed the progress and development of various technologies that have helped the development of smart roads.”

In the future, they say that smart roads will generate greater automation, greater energy efficiency, lower cost, better public safety, cleaner air, fewer accidents and deaths, and therefore will improve the overall quality of life of city ​​residents.

Roads will no longer be seen as static infrastructure, but rather as an “intelligent network,” fully aware of the situation, context and environment, the team says.

The main areas of development in road technology include:

Roads that harvest energy

There are several methods to harvest energy from roads, according to the research team behind this study.

Some use sunlight in a manner similar to solar panels, while others use mechanical vibrations produced by vehicles as they cross the road to generate energy.

Roads that produce music.

Musical roads are roads that can produce music or melodies when cars pass and can be used to indicate that someone is going to the speed limit.

They use grooves or rumbling strips, which are spaced at specific intervals on the road surface and depending on the spacing, as cars move over them it generates high or low notes and, in turn, music.

Roads that automatically weigh your car

Smart roads can monitor the weight of trucks by having stop points for static weighing or weighing movement by giving a tonnage while the driver moves along the lanes.

Roads are not only used to transport people, but also used a lot to transport goods and trucks.

Roads that automatically load your vehicle

Some cities have suggested the use of specially assigned freight lanes for autonomous electric trucks so they can load while driving.

In Sweden, about 1.2 miles of road near Stockholm have been transformed into an “electrified road” that recharges car and truck batteries.

Roads with smart wireless digital traffic signals

The idea of ​​a wireless digital traffic signal is to transmit to traffic that any change or problem is approaching, as well as the speed limit.

A receiving unit that resides in the car will pick up the signal from wireless signals and alert the driver about it, either loudly or on a screen in the car.

Roads with traffic violation detection

Traditional methods to detect traffic violations are done through pre-installed cameras and speed radar detectors with white line markings on the roads.

These methods are less effective in rainy, snowy and foggy conditions, but the new solutions involve the use of a wireless digital traffic signal or even drones on the road.

Roads with V2X: cars that speak

“It is important because it allows cars and objects to communicate and exchange crucial information, be it their position, identity, physical presence status or speed information,” the researchers said.

V2X is a technology that implies that the car automatically communicates with the things that surround it, in this case the road, the signs or even the emergency services.

“It is important because it allows cars and objects to communicate and exchange crucial information, be it their position, identity, physical presence status or speed information,” the researchers said.

Roads with intelligent intersections

Cooperative intersection security is a European project that analyzes pedestrian safety issues at these intersections and crossings.

The project uses sensors to detect vehicles and objects, along with V2I, mapping and location technologies to reduce fatal collisions and improve safety.

Paths with smart street lamps

Other uses could see them act as WiFi relay stations, weather stations, seismic sensors and even speakers to allow the transmission of emergency warnings

Street lights can already be turned on and off depending on the light detected outside and some are used to control pollution, but in the future they could also work with energy used by the road.

Other uses could see them act as WiFi relay stations, weather stations, seismic sensors and even speakers to allow the transmission of emergency warnings.

The research has been published in the magazine. Proceedings of the Royal Society A.

WHAT ARE THE SIX LEVELS OF AUTOMATIC DRIVING AUTOMATION?

Zero level – Full-time performance by the human driver of all aspects of the dynamic driving task, even when improved with warning or intervention systems.

Level one – The system achieves a small amount of control, such as adaptive braking if a car gets too close.

Level two – The system can control the speed and direction of the car, allowing the driver to take their hands off temporarily, but they must control the road at all times and be ready to take control.

Level three – The controller does not have to monitor the system at all times in some specific cases, such as on highways, but must be ready to resume control if the system requests it.

Level four – The system can deal with all situations automatically within the defined use, but it may not be able to cope with all weather or road conditions. The system will be based on high definition mapping.

Level five – Full automation. The system can cope with all weather, traffic and lighting conditions. You can go anywhere, at any time and in any condition.
