IHRE AUFGABEN Role Purpose: The role exists to deliver high-quality crowd movement analysis and static assessments that support safe, efficient, and robust crowd management planning. The Crowd Modelling Expert applies analytical judgement, domain knowledge, and structured reasoning to identify risks, bottlenecks, and improvement opportunities in pedestrian environments. The role focuses on interpreting crowd behavior and space performance, translating analytical findings into clear, actionable recommendations for planners, engineers, and decision-makers.   Technical Scope & Nature of Work Work on this project typically involves: * Analyzing crowd movement and pedestrian behavior in complex, high-density environments. * Performing static and quasi-static assessments of pedestrian spaces, where layout, operational rules, and demand patterns are critical. * Operating at the interface between quantitative analysis and operational judgement. * Supporting decision-making where safety, capacity, and operational robustness are primary concerns. The work is decision-oriented rather than academic, with a strong emphasis on clarity, practicality, and defensibility. Key Responsibilities Problem Definition & Method Selection * Analyze pedestrian movement patterns and crowd behavior in defined areas and scenarios. * Assess capacities, densities, flow rates, queuing behavior, and spatial conflicts. * Identify critical situations such as pinch points, congestion, unsafe densities, or operational weaknesses. Scenario Evaluation & Interpretation * Support the definition and evaluation of operational scenarios (e.g. peak demand, diversions, special events, constrained conditions). * Interpret analytical results in terms of risk, safety, and operational performance. * Distinguish between theoretical capacity and realistic, safe operation. Recommendations & Practical Solutions * Develop clear, practical improvement measures (layout changes, operational rules, routing strategies, demand management). * Evaluate the effectiveness and limitations of proposed measures. * Support prioritization of interventions based on risk and impact. Documentation & Communication * Produce structured reports, figures, and presentations suitable for client and stakeholder use. * Clearly document assumptions, limitations, and confidence levels. * Communicate findings in a way that is understandable to non-specialist audiences without oversimplifying. Collaboration * Work closely with simulation engineers, planners, engineers, and monitoring / technology specialists. * Align assumptions and findings across disciplines to ensure consistency of recommendations. Level of Technical Ownership Depending on experience, the role provides: * Ownership of assigned crowd analysis work packages. * Responsibility for the technical soundness and clarity of conclusions and recommendations. * Opportunity to challenge assumptions and refine scenarios in coordination with the wider team. * Contribution to improving internal analysis approaches and standards. Engineering Mindset & Working Style  This role suits individuals who: * Understand crowd behavior as a system, not just a set of numbers. * Are comfortable making judgement-based assessments under imperfect information. * Can balance safety, operational feasibility, and real-world constraints. * Prefer structured reasoning and clear communication over purely theoretical analysis. * Are motivated by improving safety and performance in complex public environments. IHR PROFIL Role-Specific Technical Focus This role specialises in crowd movement analysis and static crowd modelling, with emphasis on: * Pedestrian space performance * Crowd safety and risk identification * Operational feasibility of crowd management concepts The role complements dynamic simulation by providing interpretation, context, and operational realism.   Required Skills & Experience * Strong background in pedestrian / crowd modelling, crowd safety assessment, or transport / movement analysis. * Experience translating analytical findings into actionable recommendations. * Strong technical writing and stakeholder communication skills. * Ability to reason about safety, capacity, and operational risk holistically. Preferred Experience * Experience with complex, high-density or high-stakes environments (transport hubs, events, religious sites, urban centers). * Familiarity with pedestrian or crowd modelling platforms (e.g. Legion, MassMotion, Viswalk, PEDFLOW / PEDNET, or similar). * Arabic language skills or regional background supporting contextual understanding and coordination. Education Background * BSc, MSc, or PhD in Civil Engineering, Transport Engineering, Systems Engineering, Urban Planning, Operations Research, Applied Mathematics, or a related field. * Preferred: postgraduate focus on crowd dynamics, pedestrian modelling, transport planning, or safety engineering. Optional Training / Certifications * Crowd safety or event safety training (crowd risk assessment, crowd management). * Training on pedestrian / crowd modelling platforms. * Human factors, evacuation modelling, or safety engineering coursework. Engagement Model * Freelance or project-based engagement. * Remote-first technical work with structured coordination. * On-site presence only if technically required.
