Rapid Response Emergency AVL Systems
Anyone can put a GPS and a cell phone together and get an AVL system. It takes a lot more to create
a system that can react to 911, control traffic signals, communicate with vehicles, automatically
compute routes based on rules fire vehicle drivers and captains help define, and provide
a common operational picture of multiple agencies emergency response fleets.
Route choice may change based on time-of-day. A driver will know that in responding to incidents
in a certain area of town that he will have to drive through a school zone. If that accident happens
during a time when a lot of kids are crossing the street, it would be faster and safer to choose
a different route to avoid the school.
Of course, the obvious time-of-day consideration is rush-hour traffic congestion. But what if you
could flush that traffic out of intersections before getting there? Then you have the best of
both worlds - most direct routes, least traffic.
360VL engineers have grappled with and developed systems that handle routing rules based on
real-world input from experienced drivers and traffic engineering.
Forgetting the ongoing monthly expense and data limitations of cellular,
when there's a real crisis, what's down? Cellular phones.
You can't get through either due to the congestion or the cellular infrastructure itself is damaged.
Using cellular data for near-real-time emergency vehicle location is a recipe for disaster.
When there's a real crisis, what's busy? Voice comm. If voice comms take priority over data, location
data will be delayed or not delivered. You need an inexpensive, scalable solution
which you control to have fast, reliable AVL communication in the midst of a crisis.
360VL provides in-vehicle systems that can use multiple modes of communication: data-radio, cellular, satellite, and 802.11.
Of those modes, data-radio is by far the most cost effective and technically superior for most urban environments. Then
when you need a farther reach outside a city, switch to cellular. Outside cellular coverage, switch to satellite. The
360VL-M4 in-vehicle unit can support these modes and transparently switch between then based on availability, signal strength,
and economics.
