Evaluating Operational Features of Three Unconventional Intersections under Heavy Traffic Based on CRITIC Method

چکیده
Conventional four-legged intersections are inefficient under heavy traffic requirements and prone to congestion problems. Unconventional with innovative designs allow for more efficient operations can increase the capacity of intersection, in some cases. Common unconventional include upstream signalized crossover intersection (USC), continuous flow (CFI), parallel (PFI). At present, an increasing number cities using such improve performance their intersections. In reconstruction original or design new intersections, question how reasonably select form becomes particularly critical. Therefore, we selected a typical Xi’an optimization investigated data this intersection. The operations, respect four solutions conventional USC, CFI, PFI, were evaluated VISSIM software. Then, suitability each solution different situations CRITIC (CRiteria Importance Through Intercriteria Correlation) method, which is multi-criteria decision-making (MCDM) method that enables comprehensive integrated evaluation by taking into account comparative intensities conflicting character among indices. results show only applicable case very low volume; PFI has advantage moderate high CFI performs better USC generally inferior although it greater improvement, compared solution, few

Evaluating the Operational Features of an Unconventional Dual-Bay U-Turn Design for Intersections
Median U-turn intersection treatment (MUTIT) has been considered an alternative measure to reduce congestion and traffic conflict at intersection areas. The MUTIT is sometimes difficult to implement in the field because it requires wide median on arterials for U-turn vehicles. The objective of this study is to introduce an unconventional U-turn treatment (UUT) for intersections which requires l...
متن کاملEvaluating effects of eco-driving at traffic intersections based on traffic micro-simulation
Eco-driving is an initiative driving behavior which aims to reduce fuel consumption and emissions from automobiles. Recently, it has attracted increasing interests and has been adopted by many drivers in Australia. Although many of the studies have revealed considerable benefits in terms of fuel consumption and emissions after utilising eco-driving, most of the literature investigated eco-drivi...
متن کاملClassification of encrypted traffic for applications based on statistical features
Traffic classification plays an important role in many aspects of network management such as identifying type of the transferred data, detection of malware applications, applying policies to restrict network accesses and so on. Basic methods in this field were using some obvious traffic features like port number and protocol type to classify the traffic type. However, recent changes in applicat...
متن کاملEffect of Gap Acceptance Behavior of the Right Turning Vehicles on the Major Road Stream for Uncontrolled Three-Legged Intersections under Mixed Traffic Conditions
Uncontrolled intersections are the intersections where there are no external signs or signals to control the movement of vehicles. In mixed traffic conditions priority rules are often violated by the road users. In All-way-stop-controlled intersections (AWSC), the vehicle should stop themselves before they enter the intersection and should check whether any vehicles are present in the other app...

1 Pedestrians and cyclists are vulnerable road users and despite their limited presence in traffic events, these 2 two groups have the most collisions resulting in injuries and fatalities. Due to problems regarding data 3 collection for pedestrians and cyclists, there is a shortcoming in the field of road safety with regards to the 4 availability and quality of data for non-motorized modes.
