Abstract:

As the intersecting points of crossing traffic flows, air route intersections are the major bottlenecks in the world’s airspace due to restricted airspace and rapid growth of air traffic. In order to reduce controller workload and maintain traffic safety, air traffic operation units in China devised the idea of “overpasses” at busy intersections. The basic idea is to strategically separate flows of aircraft on intersecting routes vertically by allocating distinct flight levels to them. In practice, aircraft are required to maintain an agreed flight level en route long before they cross the int

Abstract:

Intersections experience a disproportionate share of traffic crashes, injuries, and fatalities because of the increased number of conflicting traffic movements at these locations. These issues are particularly pronounced at rural locations where speeds are generally higher and most intersections are either stop- or yield-controlled. Ideally, intersecting roadways should be oriented at as close to a 90-degree angle as possible. However, intersection design can diverge from this preferred configuration and result in a skewed intersection. Skewed intersections have been found to cause safety and

Abstract:

The paper studies the complementarity of the methods from the field of traffic flow theory: methods of traffic flow intersecting intensity and the method for the at-grade intersection capacity analysis. Apart from checking mutual implications of these methods, the proportionality of mutual influences is assessed. Harmonized application of these methods acts efficiently on the entire traffic network, and not only on the intersections that are usually incorrectly represented as the only network operators. Theoretical considerations are illustrated by a practical example. KEY WORDS: traffic flow

Intersection safety is one of the most important issues in transportation. Traffic crash analysis—the most popular method to evaluate or assess the safety performance of an intersection—has been used for a long time. However, it is based on a lot of crash data, which need to be accumulated over a long period. In addition, traffic crashes sometimes occur randomly as a result of human driving behavior. Therefore, without sufficient data and crash history, traffic crash analysis may not give an overall evaluation of an intersection's safety performance. This paper introduces an approach to evalua

Abstract:

An urban intersection group consists of a set of intersections which are geographically adjacent and strongly correlated with each other. It is an effective way to relieve traffic congestion in the networks to set the key intersection of the road network as the core, radiate outward to find the scale of its influence and divide the intersections into groups according to their relevance. Determining intersections group is the fundament of improving traffic control. Therefore, analyzing the associated features of intersections group and the research method of determining the scope of intersectio

Abstract:

The severity of accidents can show the dangerous of intersections directly, however, the safety of intersections which have not accident data could not be evaluated easily. This paper introduced “Intersection Dangerous Parameter (IDP)” model to quantify intersections’ safety. Because IDP is calculated based on Intersection Conflict Dangerous Parameter (ICDP) and Intersection Accident Dangerous Parameter (IADP), IDP model can help to evaluate the safety of intersections which have not accident data. Rely on Chinese and American data, IDP model is calibrated and the safeties of three type inters

The exclusive pedestrian (hereinafter P) phase with a diagonal crossing is routinely introduced to improve P safety at high-volume intersections. The article analyses and evaluates the feasibility of the exclusive P phase and diagonal crossing at single-level smaller intersections, identifying the advantages and disadvantages of the exclusive P phase and diagonal crossing from the point of view of time losses. In the experimental part, traffic flow modelling is carried out. The traffic flow simulations show that an exclusive P phase is most beneficial in terms of time losses at an intersection

As an important index on evaluating intersection traffic efficiency, vehicle average delay played more and more roles on traffic prediction and evaluation modeling, this paper proposed an intersection signal warrant model using average delay which can evaluate traffic efficiency.

In this model, traffic volumes of major and minor approaches are main variables which are to argue whether the intersections need to be si

As society grows, the urbanized population proliferates, and urbanization accelerates. Increasing traffic problems affect the normal process of the city. The urban transportation system is vital to the effective functioning of any city. Science and technology are critical elements in improving traffic performance in urban areas. In this paper, a novel control strategy based on selecting the type of traffic light and the duration of the green phase to achieve an optimal balance at intersections is proposed. This balance should be adaptable to fixed behavior of time and randomness in a traffic s

The severity of traffic congestion has increased in Baghdad city and influenced the public’s perception of the community. Extended travel time is experienced by users of the urban street system, so optimal traffic operation with a coordinated traffic signal system becomes necessary. Also, it is needed to alleviate congestion and progress traffic movement along the urban corridor. This study aims to evaluate and optimize traffic signal timing for selected intersections on Palestine arterial corridor and apply the coordinated signal system to reduce the users’ travel time on the selected urban c

Abstract:

Traffic congestion leads to significant losses in the form of extended travel times, fuel waste, and environmental degradation. This congestion primarily results from traffic volumes exceeding both highway and intersection capacities. To address these issues and ensure smooth traffic flow, it is crucial to evaluate intersection performance. This study focuses on the Duren Intersection in South Tangerang City, where Merpati Raya Street, Menjangan Raya Street, Cenderawasih Street, and KH. Dewantoro Street converge. The current situation at the Duren Intersection continues to cause congestion, as

Abstract:

To determine the control strategy at intersections adjacent to the expressway on-ramp, a route identification method based on empirical mode decomposition (EMD) and dynamic time warping (DTW) is established. First, the de-noise function of EMD method is applied to eliminate disturbances and extract features and trends of traffic data. Then, DTW is used to measure the similarity of traffic volume time series between intersection approaches and expressway on-ramp. Next, a three-dimensional feature vector is built for every intersection approach traffic flow, including DTW distance, space distanc

Left-turn bays may be provided at paired intersections when heavy left-turn demands exist on some approaches. Such left-turn bays may have significant effects on intersection operations. Considering the settings of left-turn bays, two single-objective optimization models are developed for paired intersections with uncoordinated and coordinated signals, respectively. Numerical examples are fulfilled to demonstrate and compare the formulated models, and the orthogonal simulation experiments are carried out. Assuming that the relevance of traffic flow exists, the results show that the optimized e

Abstract:

Alternative intersection layouts may reduce traffic delays and/or improve road safety. Two alternatives are reviewed in this research: ‘priority-controlled Seagull intersections’ and ‘priority-controlled intersections with a Left Turn Slip Lane’. Seagull intersections are used to reduce traffic delays. Some do experience high crash rates, however. Left Turn Slip Lanes allow turning traffic to move clear of the through traffic before decelerating, thereby reducing the risk of rear-end crashes. Although there is debate about the safety problems that occur at Seagull intersections and Left Turn S
