الملخص الانجليزي
The main objectives of this research were to utilize vehicle tracking technique of GPS to measure and analyze operating speed, travel time, and delay time for urban arterials and to develop operating speed models to estimate speed profile based on roadway environments. Statistical regressions were carried out to establish useful models to estimate operating speed at segments and horizontal curves, and acceleration and deceleration distances from mentioned variables. Results of this investigation indicated that: 1) On-street parking, section width, corridor function, number of median opening, number of horizontal curves, length of corridor, number of access points, and number of humps were found to be the most significant contributors to operating speed while the significant variables of horizontal curve model were entering speed, deflection angle, posted speed limit, and combination of horizontal curve and vertical curve; 2) Minimum length of study corridor can be determined after analyzing and understanding vehicle acceleration and deceleration characteristics from vehicle tracking of GPS that related with final speeds or approach speeds, and posted speed limits.
