Smart intersection without traffic lights

Smart interchanges in the future will contribute to reducing traffic congestion while increasing the efficiency of using roads.

When vehicles such as cars are wirelessly connected and communicate with each other through a unified network, traffic lights can become unnecessary "surplus" .

According to a recent study by the Massachusetts Institute of Technology (MIT), car sensors can "communicate" with each other to help the car move easily between intersections instead of stopping in front of traffic lights.

This study confirms that the idea of ​​a traffic system without a signal light is easy to design . If this idea is applied in practice, traffic flow can be doubled by optimizing the time to use the roads. Not to mention, if you spend time waiting for signal lights, we can save a lot of useful time and avoid traffic jams.

Current and future models will certainly be equipped with technology to connect to the road system.

In big cities, smart intersections with the ability to regulate traffic flow may soon replace traffic lights. We will see the flow of cars, pedestrians and cyclists moving into a serial and unified chain.

Arstechnica said, research is based on mathematical models. Scientists want to learn, build a scenario, where high-tech cars use sensors to calculate safe distances when traveling at intersections.

Carlo Ratti, director of SENSEable City Lab at MIT, said: "The intersection is a complicated place, because there will be two flows on the same road. The design of intelligent intersections creates a system. Transport systems work more efficiently, because you can ensure vehicles move in the most accurate route. "

The flow system at smart intersections does not help vehicles move faster. However, this is the most effective way to create a more consistent and stable flow of traffic.

According to research firm Gartner, most vehicles have been equipped with Internet connectivity for the past four years. By 2020, it is expected that about 250 million vehicles will be connected to the Internet thanks to the wireless network expansion process.

According to Gartner, a wireless communication channel will help connect the vehicle system and share information between different transport infrastructure. At the same time, the technology of self-driving cars also helped to develop.

Quite a number of cars on the market have the ability to warn danger and traffic conditions.

Currently, many car models on the market have the ability to warn danger and traffic conditions. Some may even choose to avoid congestion, traffic signal processing, and smart travel to reduce fuel consumption.

At the recent Geneva International Motor Show, automotive electronic components manufacturer Harman announced a partnership with chip maker NXP to launch the technology platform LIVS Connected Car Compute Platform. This technology allows sending alerts to surrounding vehicles, for example traffic lights, signs or dangerous situations ahead.

Vehicle technology and infrastructure have been developed quite synchronously over the years. However, MIT acknowledges, we still need to continue further research before considering "wiping out" traffic lights.

"In many cities, intersections with traffic lights are relatively close to each other. But it is difficult in how to replicate these smart intersections across every urban route , " the report said. Research has written paragraphs.

Ratti is optimistic about sharing, if we solve the problem right from the first crossroads, the traffic on the whole system will be resolved smoothly.

It is known that the study was published in the recent scientific journal PLoS ONE.
