BSM Analysis Results
§DMA
□The data is the right
set of data. Some Applications will
work (spot specific). Need storage capabilities and
likely other communication mechanisms to truly gain value. Possible
approach:
▪Vehicles transmit BSM Part 1 plus
key Part 2 elements less frequently
▪Transmit via DSRC when
available, Cellular otherwise
§Weather
□The Data in BSM is
sufficient. Possible approach:
▪“Black Ice” warning requires
near-instantaneous information while other algorithms operate with
data rates from once per second to once every 30 seconds
▪15 observations per
segment (e.g., 1 mile) per time step (e.g., 15 min) should be sufficient for
confidence in the application outputs
▪Bandwidth required for
data transmission is minimal (85-365 bytes)
