Demand can be concentrated overnight at accommodation sites, then shift to a few transport corridors during peak times. Those peak times are also when safety risk and operational sensitivity are highest.<\/p>\n\n\n\n<p>We explored this issue in Mina, Saudi Arabia, during the Hajj. Mina operates as a temporary tented city during this major religious festival. During the festival, large flows of pilgrims move slowly from the tented city towards the focal point of the festival, Jamarat Bridge (where they \u2018stone the devil\u2019) along a network of pedestrian walkways or corridors.<\/p>\n\n\n\n<p>While we focused specifically on health services, the same logic applies to other &nbsp;services that trigger stopping and queuing, for example water distribution, <a href=\"https:\/\/blog.ptvgroup.com\/en\/user-insights\/ptv-blog_stadium_traffic_simulation_vissim_viswalk\/\" target=\"_blank\" rel=\"noreferrer noopener\">security checks<\/a>, toilets, and wayfinding information sites.<\/p>\n\n\n\n<p><strong>The core question:<\/strong> Where should services be placed in a temporary city, so they remain accessible during peak movements, without creating bottlenecks through people stopping and queuing?<em>Note: This article is based on the academic paper <\/em><a

id=\"h-pedestrian-simulation-for-major-events-method\"><strong>Pedestrian simulation for major events: method<\/strong><\/h2>\n\n\n\n<p>This example of pedestrian simulation for major events uses a combination of techniques, not a single modelling technique. Specifically, we combined two complementary methods:<\/p>\n\n\n\n<p>First, <strong>location-allocation models<\/strong> identified optimal service locations to improve walking-distance coverage for a dispersed population. These models effectively minimize the distance people must travel to access a given number of services.<\/p>\n\n\n\n<p>Second, we created a <strong>pedestrian microsimulation<\/strong>, or agent-based, models in <a href=\"https:\/\/www.ptvgroup.com\/en\/products\/ptv-vissim\" target=\"_blank\" rel=\"noreferrer noopener\">PTV Vissim<\/a> and <a href=\"https:\/\/www.ptvgroup.com\/en\/products\/pedestrian-simulation-software-ptv-viswalk\" target=\"_blank\" rel=\"noreferrer noopener\">PTV Viswalk<\/a>. These models tested whether the candidate locations would remain safe locations during peak pedestrian traffic movement. Merge points or junctions, pinch points, bottlenecks, and service entrances and exits can affect safety at peak times.<\/p>\n\n\n\n<p>The key point is combining methods. Location allocation supports the search for optimal service locations. Agent-based modeling supports understanding how individuals (or agents) react around those service locations. <\/p>\n\n\n\n<p>Used together, these methods reduce the risk of an optimal service location failing due to congestion or trampling, which can lead to injuries or even death. The Hajj, for example, has experienced many tragic deaths from stampedes around queuing pedestrian traffic.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-night-time-baseline-stationary-demand\"><strong>Night-time baseline: stationary demand<\/strong><\/h2>\n\n\n\n<p>We started with a stationary demand pattern in which the population is concentrated in accommodation areas (the tented city) overnight. In that state, we compared the locations of existing health services with a modeled \u201coptimal\u201d alternative set that improves accessibility.<\/p>\n\n\n\n<p>This baseline is valuable for two reasons. First, it quantifies coverage when demand is stable. Second, it provides a defensible starting configuration for service planning.<\/p>\n\n\n\n<p>However, it also exposes a limitation. The nighttime population distribution can become less relevant when the crowd starts moving. <\/p>\n\n\n\n<p>Thus, the question changes. An analysis based on nighttime coverage alone is insufficient. It is also important to consider where people will be during peak-time movements.<\/p>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6a220bfc54401&quot;}\"

nighttime population distribution into movement patterns toward the Jamarat Bridge. This created a transient demand layer along the pedestrian network.<\/p>\n\n\n\n<p>For practitioners, this represents a critical change in perspective. We are no longer optimizing service locations based solely on the nighttime population. Instead, we optimize service locations based on demand along the pedestrian networks, thus making time of day crucial.<\/p>\n\n\n\n<p>This transient demand view also supports operational sensitivity tests. Route closures and incident response measures (e.g., in the event of accidents or emergencies) may trigger rerouting. When that happens, congestion can form quickly elsewhere. Service accessibility may also need to change. A plan that ignores these demand shifts has a fragile design.<\/p>\n\n\n\n<p>Therefore, we used the moving-demand representation as the basis for the next step.<\/p>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6a220bfc5541b&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6a220bfc5541b\" class=\"wp-block-image size-full wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"1017\" height=\"588\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H4.png\" alt=\"pedestrian simulation for major events, allocating pedestrian demand along routes to Jamarat Bridge\" class=\"wp-image-30601\" srcset=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H4.png 1017w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H4-623x360.png 623w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H4-768x444.png 768w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H4-300x173.png 300w\" sizes=\"auto, (max-width: 1017px) 100vw, 1017px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"Enlarge\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Allocating pilgrims along the pedestrian road network to the Jamarat Bridge<\/figcaption><\/figure>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6a220bfc55968&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6a220bfc55968\" class=\"wp-block-image size-full wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"1223\" height=\"850\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H5.png\" alt=\"pedestrian simulation for major events, rerouting impacts from a road closure\" class=\"wp-image-30599\" srcset=\"https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H5.png 1223w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H5-518x360.png 518w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H5-898x624.png 898w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H5-768x534.png 768w, https:\/\/blog.ptvgroup.com\/wp-content\/uploads\/2026\/06\/H5-288x200.png 288w\" sizes=\"auto, (max-width: 1223px) 100vw, 1223px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"Enlarge\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Congestion builds on surrounding roads when 204 Road is closed<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-re-optimize-for-peak-corridors\"><strong>Re-optimize for peak corridors<\/strong><\/h2>\n\n\n\n<p>Next, we re-ran the location-allocation models using the transient demand patterns.

Specifically, it cannot depict the interaction between stopping, merging, and queuing at service entrances and exits.<\/p>\n\n\n\n<p>PTV Vissim with PTV Viswalk addresses this operational gap. It allows you to understand pedestrian behavior at potential locations where problems may occur, such as pinch points around service locations.

The simulation described above revealed a trade-off. If a service is located directly on or very close to the main transport corridors, even modest stopping behavior can trigger queuing and potential trampling. Congestion then forms at the worst possible place: on the dominant movement paths.<\/p>\n\n\n\n<p>We tested a mitigation strategy that could be applied to other major events. We moved the optimal service locations away from the main corridors and created a dedicated waiting area with an organized queuing layout. The intent is straightforward. The service remains accessible, but individuals wait off the main transport corridors.<\/p>\n\n\n\n<p>Thus, this is an optimal design question, not just a location question.
