Road safety and IoT

Mobility is one of the key factors to consider in order to make cities more efficient, a necessity taking into account the millions of citizens travel to work or study centers in their vehicles. Taking into account that in our country there are about 492 vehicles per 1000 inhabitants, an effective management becomes essential to guarantee security. That improvement in management has arrived with Internet of Things, it will make daily transportation more efficient and secure.

IoT is already working to ensure road safety in areas such as vehicle maintenance, improved circulation, navigation, and monitoring environmental conditions or the state of the roads. IoT obtains the majority of its data with the help of connected cars. These incorporate a large number of sensors that establish communication with the cloud, other vehicles and devices. Thanks to this it provides data and information of great utility for the improvement of road safety.

The connected cars allow the constant monitoring of basic aspects of the vehicle to ensure its maintenance. Drivers can, for example, have real time information about the pressure and temperature of tires or other parameters such as fluid levels, deterioration or the state of the battery. All this helps to avoid breakdowns and, therefore, the prevention of accidents.

Connectivity also allows monitoring the flow velocity in real time so you can warn drivers on the screen of their cars that they are exceeding the speed limit. They also warn the pilot parking in prohibited areas or other behaviors that do not comply with the law, thus avoiding penalties for drivers.

One or more of the fundamental data to guarantee road safety of the connected cars is the geolocation. Thanks to it, connected cars can communicate with each other, so that, depending on the speed and position of each vehicle, collisions are avoided, like maneuvers involving emergency braking.

The geolocation also provides a constant update of traffic conditions, which makes it possible to send notifications about incidents on the roads, as well as the proposing the most efficient route.

In addition to the state of the traffic, thanks to IoT drivers can receive updated information on the state of the roads (potholes, ice, grade changes, black spots, etc.).

Other IoT devices like intelligent traffic lights communicate with the sensors of connected cars. Drivers and receive information about their status (color and when they will change), which reduces the number of accidents and improves circulation.

Also in case of emergency connected cars have automatic warning mechanisms for emergency services, providing rapid attention that can be decisive to save lives. In addition, some vehicles incorporate fatigue sensors capable of detecting deviations in the driver’s normal behavior pattern and emit an alarm if there is a danger that he will fall asleep.

As we have seen, IoT has a wide range of applications in the field of road safety, which will be progressively integrated into the streets in the coming years. By 2025, the market for advanced driver assistance systems (ADAS) is expected to grow to about 36 billion euros.
