9.  Mishaps can be avoided.
 RF communication units cover 1000mts max hence
will be useful for school , hospital areas .
 Speed of the vehicles can be controlled in such areas.
 Traffic violations also can be avoided.
 Accidents can be prevented by drunken drivers.

10.  The RF transmitters placed at the estimated
hazard points need to checked for its
working constantly.
 During heavy rain and storm conditions
units have to be more robust.
