The operational performance of the unconventional median U-turn (MUT), which has been
implemented for several years in Cairo, Egypt, is analyzed and compared to baseline …

Mega elliptical roundabout is a new intersection on rural multilane highways. This
intersection was developed in a previous paper using simulation data, and the authors …

With the increasing demand on today's roadway systems, intersections are beginning to fail
at alarming rates prior to the end of their design periods. Therefore, maintaining safety and …

Many state and local transportation agencies have considered using U-turns as alternatives
to direct left turns from driveways or side streets. Median designs are used that prohibit left …

The first objective of this study was to provide designers with a model that would help them
assess the suitability of implementing an unsignalized restricted crossing U-turn (RCUT) …

The waiting time at the stop line, one of the factors affecting the gap acceptance behavior,
was investigated in this study. The study focused on the u-turn movement of passenger cars …

Direct left turns (DLTs) could cause traffic slowdown, delay, stops, and even accidents on
intersections, especially on no-median roads. Channelization and signalization can …

Hook turn (HT) is a unique traffic regulation rule for right‐turning vehicles at intersections (in
the system where driving is on the left), which was proposed in Melbourne to improve the …

A new median treatment technique using longitudinal channelizers has been used in Florida
as an alternative to the traditional permanent concrete barrier. However, the effects of the …

In Brazil, roadway intersections are designed based on the precepts contained in manuals
prepared by official government agencies and documents such as the Highway Capacity …
