Smart Roads Start with Smart Infrastructure

With smart road technology, a safer and more sustainable future of transportation is right around the corner.

Benefits of Smart City Roads:

  • Multimodal sensors and edge computing help speed up the flow of traffic with real-time processing, reducing congestion and emissions.

  • Smart road technology will help optimize traffic flow and improve safety. It can also help give citizens back nearly 60 hours per year.1

  • Smart roads can alert first responders of accidents or help city planners identify problem areas.

Roadways are key to a thriving economy and critical to our future. Today, cities are facing pressures to respond to urbanization, streamline traffic flow, reduce pollution, and help improve safety. Smart road technology helps city planners and governments address these challenges head on. From traffic management, to pedestrian and vehicle safety, to environmental monitoring, the Internet of Things (IoT) is making roadways more intelligent, efficient, and well managed.

What Is Smart Road Technology?

With new pressures for cities to develop more-effective roadways and highways, smart infrastructure is essential for modernization. Smart city roads built on IoT technologies make it possible for cities to collect and analyze data to improve day-to-day traffic management and adapt for long-term transportation needs. With IoT sensors, cameras, and radar, data can be analyzed in near real-time and used to improve congested roadways, streamlining traffic flow. Data can also be sent to the cloud for long-term analysis, providing critical insight for efforts such as reducing CO2 emissions or improving road conditions.

Edge computing opens myriad possibilities for smart and connected roads. It enables low latency for the analytics and artificial intelligence (AI) that power smart road infrastructure, like adaptive traffic lights and integrated roadways. For example, traffic lights can automatically adjust their timing based on sensor data, enhancing the flow of traffic, or change signals to help protect others on the road from dangerous drivers.

Benefits of Smart Roads and Smart Infrastructure

There are many types of devices that enable smart road technology: speed sensors, acoustic sensors, IP CCTV cameras, smart traffic lights, condition/weather monitoring systems, and digital signage. When these devices collect and analyze data in near real-time, cities can realize several benefits:

  • Less-congested streets. For an average US citizen, congestion costs 99 hours of their time and USD 1,377 each year.2 Smart road technology can track vehicles and adjust traffic lights when there are fewer or no cars approaching, helping prevent bumper-to-bumper traffic. This could help drivers and passengers save 9.4 hours each year.1
  • Improved traffic and pedestrian safety. Traffic-monitoring solutions powered by computer vision can detect vehicles, pedestrians, and bicyclists to help enable safety practices. In the event of a crash or crime on the street, smart devices can immediately alert first responders.
  • Enhanced parking and e-tolling. E-tolling reduces congestion by using license plate recognition and vehicle tracking to automatically charge highway and bridge tolling fees—all without making vehicles stop or slow down.

By sending select data to the cloud to be analyzed over time, cities can make continual improvements in traffic management, road maintenance, and environmental quality, for example:

  • Identifying problem areas. Analytics can help detect intersections or other sites that have a high rate of collisions or near misses between vehicles or pedestrians. This helps cities determine if the site would benefit from a yield or stop sign, crosswalk, or traffic light.
  • Improving pavement conditions. Over time, streets erode or weather away. With road condition monitoring, cities can assess pavement conditions and act accordingly. According to the Minnesota Department of Transportation, if cracks in pavement are addressed early enough, cities can pay roughly USD 62.50/lane/km/year, compared to USD 1,000/lane/km/year if not addressed properly.3
  • Reducing pollution. Smart infrastructure can help reduce carbon emissions from daily transportation by optimizing traffic flow to avoid idling engines. Cities can also help reduce pollution by understanding where to best place electric vehicle charging stations.

For an average United States citizen, congestion costs 99 hours of their time and USD 1,377 each year.2

Striving for Intelligent Transportation Policies

Policies and standards are critical for deploying IoT technologies in transportation. As a member of 5GAA, Intel is working with policy makers, automakers, manufacturers, and infrastructure owner-operators to deploy cellular vehicle-to-everything (C-V2X) around the world. This 5G standards–based technology helps ensure that vehicles, infrastructure, and other road users are connected and can mobilize safely. Intel has also been an active member of technical bodies and contributes to standards development for collaborative perception, maneuver coordination, and misbehavior detection.
