Observability and controllability are two critical requirements for a partially observable
transportation system. This paper proposes a stepwise signal optimization framework with …

With the development of modern wireless communication technology, especially the vehicle
infrastructure integration (VII) technology, vehicles' information such as identification …

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 …

Traffic jams in large cities, in addition to having a very high economic cost, cause an
increase in emissions generated by vehicles over the same route being driven under normal …

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 …

The allocation of exclusive bus lanes is a strategy for giving priority to buses and improving
the efficiency of the urban transportation system. However, in the traditional exclusive bus …

Existing unconventional intersection designs mainly apply to large intersections, such as the
intersection of two major roads, in which there are numerous lanes on each leg and the …

A newly proposed unconventional intersection design, exit lanes for left-turn (EFL)
intersections, has been demonstrated to be very promising for capacity improvement …

This article focuses on the optimal traffic control strategy for a tandem intersection with
presignals. First, the impact of a lane assignment scheme at presignals on the operational …

In the wake of traffic congestion at intersections, it is imperative to shorten delays in corridors
with stochastic arrivals. Coordinated adaptive control can adjust green time flexibly to deal …
