are usually exit ramps or other destination points.
The travel time tasks calculate the time needed to travel through each segment. This infor-
mation is then used to produce a current travel time for every valid entrance/exit pairing.
The output is organized by routes.
Note
The system will not produce a travel time that would require motorists to break the
speed limit in order to match it. This means that if the current data indicates a speed
that is greater than the speed limit then the speed used in the final calculation will
be the speed limit.
Users also have the option of overriding the current travel times. This can be done in two
different ways. The first is to override the travel time for one or more segments. When this
option is used the system just uses the manually entered time for the overridden segments
instead of calculating a time. The second method is to override the entire route. In this
mode the system does not calculate any times and instead passes along the user entered
message as the output for each travel time. This option was designed for cases of extreme
conditions such as severe weather, major accidents, construction, public events, and others
as deemed necessary.
