Global Evacuation Routing Simulator

A teaching simulator for pedestrian evacuation routing and shelter reachability under a debris-blockage scenario. Set the parameters, then click anywhere on the map to plot routes.

Method and limits

Routes are generated from mathematical offset paths, not a real street network — this is a teaching tool for scenario building and general DRR orientation, not an operational routing engine. Official evacuation guidance must follow regional municipal directions.

Predictive micro-routing network modeling, emergency shelter accessibility, and structural debris blockage forecasting.

Evacuation Parameters

Scenario Timeframe Nocturnal Event (High Panic / Low Visibility) Diurnal Event (Standard Transit Mode) Structural Debris Risk (Building Density) High-Rise Historic Core (Severe Blockage Risk) Modern Planned Urban Grid (Moderate Risk) Suburban / Low-Density Zone (Minimal Risk) 🏃‍♂️ DRR Action: Set your structural debris parameters, then click anywhere on the map to plot immediate emergency evacuation vectors and calculate shelter reachability.

Evacuation System Guide

🟢 Optimal Assembly Point: The highest efficiency path calculated using isotropic frictionless velocity equations. Represents primary immediate life-safety zoning.
🟡 Alternative Shelter Vector: Calculated backup routing path deployed in the event that primary structural masonry collapse impedes main arterial roads.
🔴 Friction & Blockage Index: Cross-references kentsel density inputs against pedestrian panic matrices to quantify route degradation parameters.

Evacuation Network Topology & Pedestrian Routing Kinematics

This simulator models crowd egress dynamics across structural networks under disaster duress. Rather than generating simple straight Euclidean vectors, the engine maps mathematical multi-segmented spatial node paths to mimic non-linear kentsel street layouts.

1. Pedestrian Velocity Model

Baseline walking speeds are calibrated to standard egress parameters ($1.2 m/s$). The engine factors in panic modifiers under nocturnal settings to alter travel times.

2. Debris Vulnerability Probability

Using stochastic probability distributions, the route segments assess collapse likelihood inputs. High indexes trigger route redrawing to prioritize wider, open buffer fields.

📢 Sendai Framework Compliance: Enhancing multi-hazard early warning systems and disaster risk information (Target G) requires actionable, micro-level community routing data to lower personal injury indices.

Data Architecture: Operates entirely client-side on local geodetic coordinate grids, utilizing light map layer renderings from the CARTO network.

Disclaimer: This application serves purely as a research simulator for strategic educational purposes and general civil defense awareness. Operational evacuation routing must comply with regional municipal guidelines.
