“…It was concluded that the proposed UAIDs reduced the overall delay and the total travel time while the average speed increased. However, it was also concluded that the heterogeneous traffic influenced the proposed UAIDs' efficiency (Shokry et al, 2020). To improve the operational and safety characteristics of an existing major signalized arterial intersection in Saudi Arabia, a work investigated the efficiency of implementing an unconventional intersection design, the Double Continuous Flow Intersection (DCFI) configuration.…”

“…Fundamentally, UAIDs aim to increase the efficiency of major intersections by reducing the number of turning movements and signal phases. Additionally, they focus on minimizing potential conflict points at intersections, particularly where left-turning traffic intersects with straight-moving traffic (Corriere and Guerrieri, 2013;Shokry et al, 2020).…”

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.

“…UAIDs includes many intersection types, like the left-turn bypass intersection, and the displaced left-turn (DLT) intersection. Shokry et al, [10] compared the proposed DLT intersection and superstreet median intersection with existing conventional signalised intersections. The simulation results showed that the performances of the proposed DLT intersection and SSM intersection were better than their conventional counterparts.…”

Various unconventional arterial intersection designs (UAIDs) have been proposed as novel approaches to alleviate congestion at signalised intersections. However, little research has focused on the UAIDs under mixed traffic flow. In Malaysia, a type of unconventional arterial intersection, i.e., the left-turn bypass intersection, is very common. Hence, an alternative two-lane left-turn bypass intersection layout is proposed and compared with two other layouts under mixed traffic flow. An existing intersection in Pulau Pinang, Malaysia is selected as the location of our case study. To compare the three layouts, the state-of-the-art traffic micro-simulation software SUMO is used to model, analyse and estimate operational performances of the studied intersection layouts. To make simulation results more reliable, the simulation model is validated using the GEH empirical test. The performance indicators delay, travel time, speed, and number of stops are used to evaluate the three layouts for low, medium and high traffic volumes. The simulation results show that the left-turn bypass intersection outperforms the intersection without any bypasses, and the proposed intersection performance is better than the two other considered intersections. More specifically, the average delay of the proposed intersection is lower by 2.54s and 4.4s compared to the two other considered intersections in high traffic volume, respectively. Thus, this proposed intersection could be used in urban cities with traffic demand and congestion issues similar to those in this study.
