Georgia DOT HERO Units (Highway Service Patrol) Talkgroups

Northwest Corridor units cover I-285 from GA-400 to I-20 on the west side, I-75 from I-285 out on the northwest side, the Northwest Corridor Express Lanes, and I-575. These units use Northwest Dispatch channel at all times.

South units cover the South Metro Express Lanes and seem to cover I-85, I-75 and I-675 roughly outside I-285 on the south side. These units use South Dispatch channel at all times.

Zone 1 and 3 collectively seems to cover I-85 from North Druid Hills south through the city to I-285 on the south end, I-75 from roughly I-285 south through the city to I-285 on the south end, Langford Parkway, and I-20 inside I-285, and I-285 south of I-20 on both ends.  These units use Alpha Dispatch channel at all times. Unclear dividing line between Zones 1 and 3 since they are both always on A Dispatch.

Zone 2 (northeast units) cover I-85 from roughly North Druid Hills out, I-285 from GA-400 to I-20 on the east side, US-78, and GA-400. These units use Bravo Dispatch during most busy rush hours, but use Alpha Dispatch when a 4th dispatch channel is not in service.

Charlie Dispatch is very rarely used, but presumably would be used if Zones 1 and 3 were on separate dispatch channels.
