Today's transportation professionals are challenged to meet the mobility needs of an
increasing population with limited resources. At many highway junctions, congestion …

Conventional four-legged intersections are inefficient under heavy traffic requirements and
are prone to congestion problems. Unconventional intersections with innovative designs …

Displaced left-turn (DLT) intersections that resolve the conflict between left-turn and
opposing-through movements at the pre-signal are probably the most extensively used …

The use of unconventional arterial intersection designs (UAIDs) has been advocated as a
novel solution that can efficiently enhance the operational and safety performance of at …

Oversaturation has become a severe problem for urban intersections, especially the
bottleneck intersections that cause queue spillover and network gridlock. Further …

Traffic engineers are making efforts to mitigate congestion and to improve efficiency at
intersections. The symmetric intersection (SI) can increase the capacity of intersections and …

Heavy traffic volume coupled with insufficient capacity due to limited space cause most of
traffic congestion at urban signalized intersections. This article presents an innovative …

Increasing individual vehicular traffic is a major concern all around the world. This leads to
more and more oversaturated intersections. Traffic signal control under oversaturated …

Most US highway agencies recognize the importance of designing safe, short, and
comfortable paths for pedestrians. Providing such an acceptable condition for pedestrians …

As an unconventional design to alleviate the conflict between left-turn and through vehicles,
Continuous Flow Intersection (CFI) has obvious advantages in improving the sustainability …
