University and commercial labs are developing mobile apps designed to help make transportation safer, but there needs to be a better way to integrate the disparate stovepipes of information services within the transportation segment.
Clemson University professor Kuang-Ching Wang believes software-defined networking (SDN) is the solution. His research team has examined the current bottleneck for connected-vehicle technology and concludes there is no sustainable funding model for dedicated short-range communications (DSRC) technology. At the same time, other forms of wireless connectivity are in many places.
With SDN, programmers can upload rules for handling network traffic to the logic chips in routers and switches, which will enable data from DSRC systems to easily be integrated with smartphone sensor data collected via Wi-Fi or Bluetooth networks. Most analysts believe the integration will take place within the vehicle, and more automakers are building vehicles that are simply platforms.
Meanwhile, University of Nevada, Las Vegas (UNLV) professor Pushkin Kachroo says researchers at UNLV are developing smartphone applications that monitor seatbelt use in passing vehicles, and others that collect data on road service conditions and transmit it to transportation managers for potential action.
