“…In order to analyse the pedestrian movement in this area, it's important to consider factors such as the width and length of the lane (35m width and ≈ 10 km) [21], the number of people moving through it at any given time (500,000 pilgrims/hour) [23], and the speed or flow of the pedestrian traffic (depends on group classification shown in Figure 4). Observing these elements can provide valuable insights into the behaviour of the pilgrims and help identifying any areas where improvements could be made [24].…”

Crowd behavior analysis is an essential tool for understanding people mobility and movement in public spaces. By analyzing the behavior of crowds and their motion patterns through their interaction with the surrounding environment, designers can identify potential issues and implement solutions to improve safety and efficiency while enhancing urban spaces. The aim of the study is to understand the crowd behavior and movement patterns at the road between Arafat and Muzdalifah during peak times of Hajj to identify prospective overcrowding zones and problems. This has been accomplished through the study use of visual observation, video analysis, and crowd simulation modelling. The study tests the crowd behavior that heavily influenced by the physical urban features, barriers, and surrounding services. The study suggests several recommended interventions for better urban design solutions to improve pedestrian crowd flow for better crowd management. These interventions could be used as guidelines for urban designers and planners to create safer and more efficient pedestrian spaces during similar crowd situations.

“…Hence, the existing facilities at Hajj areas turn more congested due to overcrowding of pilgrims and causing limited pedestrian movements (Owaidah, et.al (2019). Abdelghany et al (2012), estimated that the peak pedestrian flow rate between Arafat and Muzdalifah had reached 500,000 pilgrims per hour and expected to increase by years. Friberg & Hjelm (2015), emphasized that pedestrian overcrowding may lead to rushes, traffic and human bottlenecks, counter flows, stop-and-go waves, crowd turbulence, and panic among the pilgrims.…”

Makkah is the holy city of Muslims which is located in the southwest of Saudi Arabia. It is the being visited by pilgrims from all nationalities every year for the annual Islamic Pilgrimage (Hajj). Hajj is the fifth pillar of Islam which is the largest annual religious pilgrimage event in the world. The Hajj management authority specifies that the current pilgrimage’s performance is challenging due to the increase of pilgrims every year. Pedestrian conflicts and uncomfortable walking environment are the crucial issues that have been identified, which are due to insufficient pedestrian facilities. Hence, this paper presents the pedestrian facilities assessment between Arafat to Muzdalifah road. The objectives of the study are to determine the available pedestrian facilities for pilgrimage from Arafat to Muzdalifah, and to suggest the suitable solution for pedestrian facilities in every 5 minutes walks. Meanwhile, qualitative methods of site inventory and observation were applied to gather the related data on the selected study area. Possible pedestrian facilities design is suggested for the purpose of future Hajj improvement.

“…These models adopt different modeling approaches to represent the pedestrians' behavior including destination and route choice, adjustment of walking trajectory, walking speed, congestion aversion, and collision avoidance. These approaches include, for example, CA models, [45][46][47][48][49][50][51][52][53][54][55] lattice gas models, [56][57][58][59] social force models, [60][61][62][63][64] agent-based models, [65][66][67][68][69][70][71][72] fluid-dynamic models, 23,[73][74][75] and mesoscopic models. 52 A recent comparison among these techniques can be found in Duives et al 44 They concluded that the models can roughly be divided into slow but highly precise microscopic modeling attempts and very fast but behaviorally questionable macroscopic modeling attempts.…”

This paper presents the main findings of a simulation-based study to evaluate incidents in pedestrian/crowd tunnels and similar elongated confined facilities, with high-volume heterogeneous traffic. These incidents, when occur, imposes hazardous conditions that always result in significant number of fatalities. The aim of this study is to understand how these facilities perform under different irregular scenarios and possibly identify potential causes of accidents. The problem of studying incidents in large-scale high-volume pedestrian facilities is that these incidents are difficult to expect or replicate. Thus, studying these facilities through real-life scenarios is almost impossible. Accordingly, a micro-simulation assignment model for multidirectional pedestrian movement is used for this purpose. The model adopts a Cellular Automata (CA) discrete system, which allows detailed representation of the pedestrians’ walkways in the tunnel. The modeling approach captures crowd dynamics through representation of behavioral decisions of heterogeneous pedestrians at the individual level. Several experiments are conducted to study the pedestrian flow in the proposed tunnel considering different operational scenarios including demand levels, heterogeneous traffic, evacuation scenario, and tunnel blockage. Results show that flow of large pedestrian volumes through a long confined linear structure, such as a tunnel, are subject to the same flow dynamics as we observe with vehicular traffic. In particular, they are subject to the formation of “clumps” and shock waves that can rapidly propagate and lead to inefficient operation, including flow breakdown with stop-and-go waves.
