SUGGESTED SCENARIO FOR PLOW TRAINS:
All plow trucks within the plow train should have the radios “Off” network to talk within the work group.
The manager/supervisor that is in control of the plow train should have his/her portable “Off” network to
communicate with plow train and have his/her mobile “On” network to listen for any pertinent network
communications.
SUGGESTED SCENARIO FOR SMALL WORK ZONES:
All vehicles entering the work zone, vehicles within the work zone, and flaggers should have the radios “Off”
network to enable the truck to truck and truck to ground communications. Vehicles leaving the work zone
should return to “On” network operations. The manager/supervisor that is within the work zone should have
his/her portable “Off” network to communicate with other within the work zone and have his/her mobile
“On” network to listen for any pertinent network communications, vehicles leaving or returning from a plant,
stockpile, authorized dump site, etc. and still a distance away.
SUGGESTED SCENARIO FOR LARGER WORK ZONES (REFERENCE TYPICAL RANGE
OF PORTABLES):
This is a field manager’s/supervisor’s decision based upon the work zone set-up, amount of intersecting
traffic, geography, known network coverage, etc. Due to the typical range of portables that the flaggers would
be utilizing, a decision needs to be made as for flaggers remaining “On” network or to be “Off” network and
relaying information with intermediate flaggers. Naturally, vehicles within the work zone would have to
remain “Off” network due to their close proximity.

“Transportation.” An example of this change is as follows: Example1: Existing talk group name is “Adams”
and new name will be “T_Adams.” Example 2: Existing talk group name is “Butler” and the new change shall
reflect “T_Butlr”. The abbreviation is due to only seven characters are available on the 800MHz display
