“…The study found that the proposed DCFI unconventional intersection design decreased the average delay per vehicle by 99 seconds and improved the Level of Service at the intersection from level F (152 s/vehicle average delay) to level D (53 s/vehicle average delay) (Bashir et al, 2021). The safety performance of the new mega elliptical roundabout interchange was analyzed and compared with eight other interchange designs and it was concluded that the mega elliptical roundabout interchange has good safety performance compared to other interchanges studied by (Mane and Pulugurtha, 2020). Researchers evaluated the performance of three unconventional intersection designs (Median U-turn (MUT), superstreet, and continuous green T-intersection (CGT)) over existing pretimed signalized intersection design along Highway 49 in the city of Charlotte, North Carolina, USA.…”

“…This issue arises due to the rapid increase in vehicle ownership relative to population and income growth (Guzman et al, 2020). Unconventional intersections and interchanges (UAIDs) show their capability to reduce traffic congestion, improve traffic operation and increase infrastructure capacity (Alozi and Hussein, 2022;Alzoubaidi et al, 2021;Ciampa et al, 2020;Corriere and Guerrieri, 2013;ElKashef et al, 2021;Hadidi et al, 2022;Jewel et al, 2022;Mane and Pulugurtha, 2020). Fundamentally, UAIDs aim to increase the efficiency of major intersections by reducing the number of turning movements and signal phases.…”

Currently, a growing number of cities are adopting the Median-U-Turn (MUT) intersection design to enhance road capacity and traffic efficiency. The critical question in selecting the right intersection design is how significantly the implementation of MUT can enhance intersection performance, focusing on three key aspects: intersection efficiency, capacity, and the environmental impact of the design. To address this question, an evaluation of operational performance under various prevailing conditions (roadway and control) was conducted using VISSIM, a microscopic simulation platform. This evaluation involved five scenarios: conventional intersections (with increased cycle length, grade separation with a signalized at-grade intersection, grade separation with a roundabout), MUT, and signalized crossover MUT at a dense urban arterial intersection in Amman, Jordan's capital. The performance was compared using several metrics: average control delay, number of stops, average travel speed and time, average stopped delay, Carbon Monoxide (CO) emissions, fuel consumption, and vehicle safety. The Criteria Importance Through Intercriteria Correlation (CRITIC) technique was subsequently used to select the optimal design. The findings indicate that the existing intersection configuration is the least effective, while the MUT with signals at the crossing U-turn points is the most efficient solution.

In junction traffic operations, vehicle delay is one of the most essential performance measures of effectiveness. It allows traffic engineers to assess the performance of a traffic system component or the efficacy of a system-wide control plan. Real-time applications such as adaptive signal control, congestion management, and dynamic traffic assignment often use this technology. Obtaining real-time data on intersection performance, such as control delay, may be time-consuming and labor-intensive. This study presents a new approach for estimating network-level real-time delay from passive traffic counting. Total Travel Delay Estimation Technique (TTD) is proposed for signalized intersection delays that can be computed by examining real-time data from arrival and departure detectors upstream and downstream of a junction. The proposed estimation method mathematically manipulated equations that relate the input-output model and vehicle O-D data acquired from the Automatic Turning Movement Identification System (ATMIS). The developed methods utilize the obtained real-time traffic detection system as input data. The proposed methods are applied for three cases: simple, semi-generalized, and generalized networks, where any of them can be used as a building TTD estimation block for the whole actual network. Results from the TTD were compared to VISSIM output, and a statistical test was conducted under varying traffic conditions (low, medium, high, and saturated). The findings show that the proposed methodology can yield stable and reliable results in various traffic volumes and turning movement conditions. Future field implementation studies for the suggested methods are recommended to evaluate the model's reliability and efficacy in real-time traffic scenarios.
