In U-turn bays near intersections, the conflict between U-turning vehicles and those going
straight-ahead results in traffic accidents since straight-ahead vehicles cannot reliably …

As the number of motor vehicles in China's cities continues to increase, the imbalance
between the capacity that existing urban roads have for construction and the demand for …

This research examines the utility of combined crash modification factors (CMFs) in
minimizing crash severity at urban roundabouts. Conventional CMFs typically assess the …

The J-turn intersection is a novel roadway design which decreases the points of conflict at
an intersection, by restricting straight crossing and left-turning movements from the minor …

As one of the unconventional intersection designs, the median U-turn (MUT) intersection
design has been confirmed to have the potential to improve intersection efficiency and …

Currently, a growing number of cities are adopting the Median-U-Turn (MUT) intersection
design to enhance road capacity and traffic efficiency. The critical question in selecting the …

This report summarizes the before and after operational performance of intersection
modifications that have been converted from traditional intersections to alternative …

To improve traffic efficiency and reduce pollutant emissions at urban road intersections,
VISSIM software was used to simulate traffic states to compare the median U-turn method …

Understanding the influence of roundabouts on operating speeds along connecting
roadway segments is important for developing facility-level operational analyses along …

Driven by the vision of eliminating road fatalities, Vision Zero initiatives have been widely
adopted by many cities around the world, with significant investment of resources in various …
