The roundabout is one type of at-grade intersection commonly seen in many countries. The
evaluation of roundabout safety is usually counted on conflict analysis of the roundabout …

This paper proposes a trajectory planner for multilane roundabouts. The goal is to enhance
the existing roundabout in terms of capacity with the help of connected automation. The …

Building safe and effective roundabouts requires optimizing traffic (operational) efficiency
(TE) and traffic safety (TS) while taking into account geometric factors, traffic characteristics …

As a newly proposed unconventional intersection design, the exit-lanes for left-turn (EFL)
intersection is found to be effective in increasing the intersection capacity with high level of …

Deep reinforcement learning has recently provided promising results on the traffic light
control optimization problem, by training neural network agents to select the traffic light …

Employing an optimal traffic light control policy has the potential of having a positive impact,
both economic and environmental, on urban mobility. Reinforcement learning techniques …

There is a growing number of studies on the traffic control strategies of signal timings and
vehicle trajectories at signalized intersections, while lane assignments are widely pre …

Roundabouts promise potential safety and efficiency benefits in the homogenous
environment of conventional vehicles. However, their performance can deteriorate if high …

The wheel tracks on highways are excessively concentrated and lead to rutting on asphalt
pavements, which reduces the service life of highway pavements. A new method is …

Traffic congestion at intersections is a serious problem in cities. In order to discharge turning
vehicles efficiently at intersections to relieve traffic jams, multiple left-turn and right-turn lanes …
