Model to Predict Speed Rates in Weaving Sections (Case Study: Tehran Principal Arterials)
Journal Title: International Journal of Fundamental Physical Sciences - Year 2015, Vol 5, Issue 3
Abstract
Due to a strong need for lane changing, in weaving sections, a type of turbulence creates a traffic flow and as a result, the speed and the capacity of the weaving section decreases. Therefore, investigation of in this regard seems to be very essential. However, because of the lack of manual control for urban principal arterials, calibration of these models is necessary as well. One of these models that are used to evaluate the level of the weaving sections service is Speed Rates Model which will be elaborated in this paper. The required data have been collected in nine Tehran principal arterials. Then, two models for prediction of weaving and non-weaving speed rates have been developed. Validations also confirm the accuracy of the developed models. The investigation of weaving speed rates reveals that speed rates for weaving vehicles reduce by increasing weaving density and rates. Also, the research on non-weaving speed model shows the speed rates for non-weaving vehicles reduce by increasing weaving density and lane changing rate. Moreover, comparison of the developed model and HCM 2010 for similar condition reveals that the developed models have the predictability more than that of HCM 2010 model.
