Travel time is the elapsed time it takes for a vehicle to traverse a given
segment of a street.
Travel time studies provide the necessary data to determine the average travel
time.
Combined with the length of the corridor under study, this data can be used to
produce average travel speed.
Travel time and delay are two of the principal measures of roadway system
performance used by traffic engineers, planners and analysts.
Since vehicle speed is directly related to travel time and delay, it is also an
appropriate measure-of-performance to evaluate traffic systems.
A study conducted to determine the amount of time required to traverse a
specific route or section of a street or highway.
The data obtained provide travel time and travel speed information but not
necessarily delay.
This term is often used to include speed and delay study.
Travel time may be defined as the total elapsed time of travel, including stop
and delay, necessary for a vehicle to travel from one point to another point
over a specified route under existing traffic condition.
