The most appropriate service measure for a two-lane highway is the combination of average travel speed (ATS) and percent time spent following (PTSF). local driver behavior traffic operation characteristics in different countries affect operational analysis results. objective this study to evaluate applicability HCM procedures on highways Iraq. Ten segments northern Iraq were selected, more than...

Operations-oriented traffic signal performance measures are important for identifying the need retiming to improve operations. Currently, most obtained from high-resolution controller event data, which provides information on an intersection-by-intersection basis and requires significant initial capital investment. Over 400 billion vehicle trajectory points generated each month in United States...

objective: to determine the epidemiological characteristics of fatal traumatic accidents in patients referred to a hospital in babol, northern iran. methods: thiswas a cross-sectionalstudy being performed during a 1-year period including all the dead trauma patients referred to shahidbeheshtihospital of babol. we included all those patients who were transferred to our center to trauma and injur...

In this paper a method is proposed for performance evaluation of road traffic control systems. The method is designed to be implemented in an on-line simulation environment, which enables optimisation of adaptive traffic control strategies. Performance measures are computed using a fuzzy cellular traffic model, formulated as a hybrid system combining cellular automata and fuzzy calculus. Experi...

Air traffic control (ATC) is a complex and demanding job reserved for highly-trained professionals. Training ATC candidates challenging as trainees are subjectively assessed by instructors who biased their own ways of working. As an effort to determine expertise objectively, this study employed clustering techniques on existing data set in which course professional controllers participated medi...
