Next-generation networks help DOT’s deliver quality motorist experience
Converged packet-optical technology enhances Department of Transportation’s intelligent transportation systems while paving the way for future automated highways.
By Daniele Loffreda – On statewide highway systems, road conditions can change without warning. Snowstorms, rockslides, vehicle collisions, traffic congestion and wildlife activity are just a few examples of sudden changes that can disrupt road travel. For Department of Transportation (DOT) traffic managers in central operations centers, accessing real-time data from remote roadside “smart” devices is critical. Trying to resolve roadside problems from afar without real-time data is like trying to steer a car that has a mud-splattered windshield. Although there may be a few clear patches, it is nearly impossible to see the whole picture.
Traffic managers need real-time access to data flowing from intelligent transportation systems (ITS) technologies, smart traffic control devices and connected vehicle applications. Combining this data with analytics software provides traffic managers a clearer view of what is happening throughout the highway system. Armed with these insights they can quickly resolve problems, dispatch emergency crews, alert motorists to pending hazards, and recommend alternative routes to their destinations.
The challenge? The enormous data volume generated by video cameras, sensors, monitoring devices, vehicle to infrastructure (V2I) and other technologies can quickly clog a network increasing congestion and outages. more>
