Modeling traffic flow at a single-lane urban roundabout
In this paper, we propose a new model to study traffic flow at a single-lane urban roundabout, using a multi-state cellular automata (CA) ring under the offside-priority rule (by which a vehicle entering gives way to one already on the roundabout). Each vehicle entering the roundabout is randomly characterized by a predetermined exit with specified probability. Driver behavior at the roundabout...
متن کاملModels of Roundabout Lane Capacity
1 Accurate roundabout capacity models are essential for optimal roundabout 2 designs, but there exists significant differences in the predicted capacities of various 3 state-of-the-art models and in their included explanatory variables. An empirical 4 study into roundabout lane entry capacity was thus performed in the U.K. using data 5 from 35 roundabout entry lanes, where various model forms a...
متن کاملMulti-lane Roundabout Capacity Evaluation
Although two-lane roundabouts theoretically exhibit excellent operating performance, in practice, safety problems arise because of inappropriate driving behavior. Turbo roundabouts, which are characterized by a much higher level of safety, are alternatives to classic two-lane roundabouts, but the capacity-related benefits derived from such roundabouts remain an open issue. Accordingly, this stu...
متن کاملSingle-Bundle PCL Reconstruction with Remnant Preservation: Midterm Follow-up
Background. Remnant preservation was developed as a routine procedure for posterior cruciate ligament (PCL) reconstruction, but it is not easy. Objectives. Our study aimed to evaluate the outcomes of a minimum 5-years follow-up of remnant preservation PCL reconstruction. Methods. The study was a prospective cohort analysis of 44 patients who underwent PCL reconstruction with remnant preservat...
متن کاملCalibration of VISSIM Roundabout Model: A Critical Gap and Follow-up Headway Approach
1 VISSIM roundabout models have been widely applied in practice to facilitate analyzing the 2 operational performance of roundabouts. To prepare a VISSIM roundabout model for analysis, 3 an essential prerequisite is to calibrate the model by adjusting parameters until real-world 4 roundabout operations are reproduced in the simulation model. Previous calibration research has 5 used qualitative ...
