Using Cellular Messages to Augment BSM for Mobility
Applications
§Most mobility applications do
not require BSMs 10 times per second
§Many applications require
data captured over a wide area, not just localized data near a roadside unit (storage and/or wide-area
communications needed)
§Possible Approach:
□Vehicles transmit BSM Part 1 plus key Part 2 elements
less frequently
□Transmit via DSRC when available, Cellular
otherwise
§Augmenting BSM with key
Part 2 elements via Cellular provides the
vehicle data needed to
support nearly all mobility applications
