THE INSTITUTEAs more and more intelligent cars and autonomous vehicles hit the road, some engineers are thinking about what can be done to smarten up the streets on which they travel.
Doing so could allow smart cars and trucks to exchange information with other vehicles, traffic-management centers, and private companies about traffic congestion, accidents, and weather conditions.
Existing intelligent transportation systems provide some of those features.
Information gathered by traffic-monitoring cameras, for example, is being used to adjust traffic signals in real time to ease congestion.
And there are some IoT pilot projects, like Austria’s Autobahn, which uses Cisco’s Connected Roadways system to link 70,000 sensors and 6,500 traffic cameras to monitor traffic and road conditions.
But no comprehensive IoT-based transportation system has been fully deployed, according to IEEE Fellow Phillip A. Laplante, author of “‘Smarter’ Roads and Highways.” The IEEE Internet of Things Magazine article covers the benefits of IoT-enabled roads, security and privacy concerns, and technical standards that could ensure interoperability.
