The purpose of this study was to investigate traffic flow characteristics at off-ramp junctions in Iranian expressways. The study was conducted on the traffic behavior in isolated off-ramp vicinity of 6-lane expressways. The database consisted of traffic flow and traffic speed information extracted from videotapes. The relationship between diverging traffic flow in the right lane of expressway ...

Connected and automated vehicles (CAVs) are expected to transform future transportation systems. Over time, these might enhance traffic efficiency safety, especially at urban intersections. Therefore, it is essential make adaptations the analysis models that currently designed for human-driven only. This paper aims assess impact of CAVs on entry capacity roundabouts develop an approach adjust v...

This paper presents a model for manual and automated traac ow. The model is based on the abstraction of vehicle activities by the space and time taken up by the vehicle engaged in the activity. The manual driver model includes the activities of vehicle following and lane change and allows for diierent levels of aggressiveness of drivers. The parameters of the activities are calibrated with real...

Calibration is a conventional method which is utilized to adapt traffic models based on local situations in order to achieve best results. One of the issues regarding the efficiency of this method is whether traffic models should be calibrated only in one or two major cities of a country or calibrated based upon a comprehensive selection of cities. Therefore, this study, which has used the actu...
