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. |
