  Wireless Infrastructure  
     
 

Innovative wireless networking technologies developed by researchers at the center can enhance information flow to and from the traveler for various purposes, including:

  
  • providing en-route information to the motorist,
  • communicating data about the state of the transportation network to a central control center,
  • imposing or removing tolls on the fly, so that they are responsive to demand placed on the transportation network, and
  • implementing advanced safety measures.
Researchers are using radio (802.11-type) rather than cellular communications for the wireless network, with initial design and validation focusing on customizing communications for drive-by tolling and Advanced Vehicle Safety System applications. The object is to achieve radio communications that are optimized for time-critical, short-duration communications without overly degrading Internet access capabilities.
