A protected left turn phase is often used at intersections with heavy left turns. This may induce a capacity gap between adjacent intersections along the arterial road among which only parts of intersection are with protected left turn phase. A model for integrated optimization of protected left turn phases for adjacent intersections along the arterial road is developed to solve this problem. T...

Roundabout is one of the most effective intersection control methods in the world. Although, they have often been used in Iran, but, the methods which are proposed to analyze roundabouts are very old and new regulations are not implemented for analyzing modern roundabouts. There are strong needs to apply new modern analyzing methods for studying roundabouts in Iran. Also, these methods should b...

Solving multi-manifolds clustering problems that include delineating and resolving multiple intersections is a very challenging problem. In this paper we propose a novel procedure for clustering intersecting multi-manifolds and delineating junctions in high dimensional spaces. We propose to explicitly and directly resolve ambiguities near the intersections by using 2 properties: One is the posi...

Aimed at prevalent violations of non-motorists at urban intersections in China, this paper intends to clarify the characteristics and insecurity of violations of non-motorists at signal intersections through questionnaire and video recording, which may serve as the basis for non-motor vehicle management with the purpose of improving the traffic order and enhancing the safety degree of signal in...

The carrier profile for InAs films grown on GaP is modeled as a first-order approximation which assumes that 90° edge dislocation intersections and the threading dislocation intersections act as shallow donors. Due to dislocation annihilation during growth, the threading dislocation intersection density decreases as the inverse of the distance x from the InAs/GaP interface, D(x)5D0x0 /(x0 1x), ...

Right turn on red (RTOR) is permitted at signalized intersection in the United States. Adequate intersection sight distances should be provided to ensure that the RTOR drivers turn into receiving lanes safely and efficiently. However, in practice it is not unusual to find signalized intersections with restricted right-turn sight distances, at which RTOR is still permitted. This research is focu...

In many cases, crashes at intersections account for over 50% of all urban road accidents. The need to reduce these crashes has fostered considerable research on the development and evaluation of traffic safety at intersections. This paper introduces a micro-level behavioral method for estimating crash potential at signalized and unsignalized intersections for different traffic characteristics. ...

As computers replace humans as the drivers of automobiles, our current traffic management mechanisms will give way to hyper-efficient protocols designed to exploit the capabilities of fully autonomous vehicles. We have introduced such a system for coordinating large numbers of autonomous vehicles at intersections [2, 3]. Our experiments suggest that this system could alleviate many of the dange...

[1] Experiments and analyses are presented to elucidate the critical control of fracture intersections on the evolution and dynamics of the liquid phase structure within unsaturated fracture networks in impermeable media. Phase structure was visualized within a thick vertical sheet of broken glass where the breaks constituted the fracture network. The critical system parameters, applied flow ra...

This paper proposes a distributed coordination mechanism between local feedback controllers that adapt the switching times of traffic lights at neighboring intersections. Some heavily loaded intersections are designated “leader intersections”. There, a local control agent sets switching times to minimize the expected queues, knowing vehicle passing times at local upstream sensors only, and send...
