Transit time represents the time between the departure of initial response
resources and their arrival at an event scene. Transit time, therefore, rep-
resents the ensuing time between assembly and set- up. In many response
scenarios and as that depicted in Figure7.6, transit time “consumes” the bulk
of most response sequences. The speed of responding resources and the dis-
tance to an event are the two primary factors affecting transit time because
time in this case is a function of both transit speed and distance.
In some instances, multiple response resources may be in the process of
transiting to an event scen ...
