Abstract
Travel time is a very important parameter in traffic engineering, this paper puts forward a new method:
least square method fit, which requires less work and proves to be convenient in data processing. By
applying the field data from some expressway in Beijing, the new method is verified in the paper and
its application conditions are analyzed. With an overall comparison among the traffic survey methods
for calculating travel time, some proposals are made for the fixed spot survey as a conclusion.
Keywords traffic engineering; travel time; least square method fit; traffic survey
