A test conducted at another roundabout validated that the entry capacity estimated from the calibrated and adjusted HCM model was consistent with the field entry capacity, and the calibrated and adjusted HCM model could predict the entry capacity of an approach to a roundabout quite accurately.doi:...
For a given heterogeneous distribution of vehicle type, there is a significant impact on queue length, delay times experienced and throughput at a fixed-cycle traffic light controlled two-way intersection and two-lane roundabout, when compared to the homogeneous case. As the proportion of long ...
In this research, a road safety assessment was developed for a two-lane roundabout, existing in Bogota, and for a proposed basic turbo-roundabout for the same intersection, in order to compare their road safety performance and determine which one offers safer traffic conditions. In that sense, ...
Roundabout Technologies is an AI-powered traffic control system that makes intersections safer, more efficient, and cheaper for cities to maintain. We use computer vision and commodity traffic cameras to build a 3D map of everything happening at the intersection in real time. We then use this ma...
Relevant to our context, DRL has also been applied to CAV control in a signalized intersection (Yang et al., 2017), an unsignalized single-lane intersection with desired speed as objective (Kheterpal et al., 2018) lane changing behavior (Wang et al., 2018), roundabout (Jang et al., ...
The average daily traffic (AADT) per roundabout is about 12500 vehicles per day. In 1988, there were 78 accidents, 5 of which were fatal and 26 of... F Alphand,U Noelle,B Guichet 被引量: 24发表: 1991年 TRAFFIC VOLUME ESTIMATION FROM SHORT-PERIOD TRAFFIC COUNTS estimate the annual avera...
The implementation of the actual models is given inmodels.js. Presently (as of November 2016), an extension of the Intelligent-Driver Model ("ACC model") is used as acceleration model, and MOBIL as the lane-changing model. We use the ACC model rather than the "original" IDM since the ...

A test conducted at another roundabout validated that the entry capacity estimated from the calibrated and adjusted HCM model was consistent with the field entry capacity, and the calibrated and adjusted HCM model could predict the entry capacity of an approach to a roundabout quite accurately....
First, we developed the simulation model of the selected intersection based on the design and traffic volume observed after the roundabout has been introduced. Then, we put the actual traffic volume observed after the roundabout has been introduced to the developed simulation model. And then, we ...
