“…Resilient road infrastructure design, addressing factors like the physical layout and geometry of roads and intersections, is critical for endurance and recovery from disruptions such as storms [16]. Resilient road designs aim to create durable structures capable of swift recovery both before and after disturbances [66].…”

“…The existing literature on this topic features studies assessing current resilience at country, regional, or city levels against disasters such as floods, storms, hurricanes, and earthquakes [7,14,15]. Various methodologies, including indicators, indices, and conceptual frameworks, have been developed and employed in case studies [9,[16][17][18]. For instance, the "R4" resilience triangle framework addressed recurrent congestion as an internal disruption on urban roads, using spatial-temporal traffic patterns compared with other freeways and signal-controlled arterial roads [9].…”

“…While the proposed metric effectively captured congestion patterns from a resilience perspective, further extensive research is required, covering diverse scenarios in varying traffic conditions. Studies [16,17] employed an adaptive strategy for traffic signal control to address disruptions at intersections, enhancing resilience by adjusting control plans during crashes. This led to a reduced overall delay time compared to conventional signal plans.…”

Urban mobility underscores the vital importance of ensuring traffic efficiency on road segments, intersections, and transportation networks, especially in challenging circumstances. In this perspective, the essential approach to improving urban intersection efficiency should involve understanding critical factors for maintaining operational performance in the face of disruptions such as storms. This paper, inspired by a systematic literature review, presents a novel heuristic for evaluating urban intersection efficiency, with resilience as its guiding principle. The methodological path was designed to address the fundamental question: How can urban intersections be designed and managed to ensure efficiency and resilience in the face of disruptions? Drawing inspiration from the Highway Capacity Manual procedure, the methodological approach encompasses both pre-storm and post-storm scenarios, comparing delay times at roundabouts and signalized intersections before and after a storm. The results reveal significant changes in delay times for traffic signals, although the choice between roundabouts and signalized intersections should be context-specific, considering factors like traffic conditions, resilience requirements, and associated trade-offs. By shedding light on the interplay between intersection design, control strategies, and urban resilience, this research provides valuable insights into integrating resilience considerations into intersection performance assessment and management strategies. It also underscores how particular intersection designs can impact efficiency and recovery, essential considerations when assessing whether a road or intersection project is resilient.

“…In a week, the time required for the change of the phase sequence of the traffic signal lights at SCTI is the signal period [ [20] , [21] , [22] ]. The short signal period of SCTI will reduce the traffic capacity of SCTI, while the long signal period of SCTI will increase the average delay time of vehicles.…”

“…Numerical results showed significant improvement in intersections' throughput when compared to a fixed-time control. Yao and Chen [23] proposed an adaptive traffic signal control strategy that responds to traffic disruptions at an isolated intersection. Dynamic phase selection is applied to adjust the traffic signal control plan adaptively during the incident stage, while the queue length dissipation algorithm is adopted to carry out optimal green time calculation during the incident recovery stage.…”

The performance of the traffic system can drastically drop when nonrecurrent congestion caused by incidents occurs. Early detection and clearing of traffic incidents will enable the mitigation of the congestion and early restoration of normal traffic conditions. The research in this paper utilized the vehicle information from the recent technological advancement in transportation systems, connected vehicles (CV), and loop-detector information for nonconnected vehicles (NCVs) and developed a novel algorithm to (1) control traffic signals for normal traffic conditions in the absence of incidents, (2) detect traffic incidents using CV/NCV information, and (3) control traffic signals during the occurrence and dissipation of incidents. All the 3 strategies were integrated into one algorithm, which runs as per the real-time traffic conditions, in the presence or absence of incidents. Space-mean speeds of the vehicles on nonincident lanes and throughput maximization criteria were taken as the indicators for the activation of specific signal timings directed at the incident-affected approach. Diverse incident scenarios were tested on a four-legged isolated intersection using the VISSIM simulation tool. Incident detection results showed a higher detection rate and lower mean detection time at higher CV penetration and higher traffic volumes, and at the incident locations nearer to the stop-line. The proposed incident-responsive signal control strategy at 40% and higher CV penetration showed better performance over EPICS adaptive signal control solution, in reducing average travel time delay and the average number of stops per vehicle.
