3. 1. SimWalk PRO in a nutshell
 SimWalk PRO is a general-purpose pedestrian simulation software for applications in urban planning, evacuation, event and traffic management…
 …for pedestrian flow analysis and management, e.g. density and bottleneck analysis, facility efficiency, safety evaluation or general operational analysis (queues, processors etc.)
 …SimWalk PRO is a decision tool to improve the sustainbility of the interaction between pedestrians and the environment

4. 1. How does SimWalk PRO work?
STEP 1: Import of simulation plan (CAD .dxf format)
STEP 2:
Model creation and definition of passenger types
STEP 3: Simulation experiments
STEP 4: Analysis of simulation results

5. STEP 1: Import of simulation plan
 SimWalk directly integrates CAD files (.dxf), one level or multi-level scenarios.
 SimDraw modul provides an integrated CAD tool in SimWalk to change and adapt CAD files.

6. STEP 2: Model creation and definition of passenger types
Creation of the spatial model and operations (escalators, stairs, elevators etc.)
Definition of passenger routes (Start-, wait and exit areas)
Selection of passenger types (e.g. elderly, business people, disabled etc.)

7. STEP 2: Definition of passenger types with profiles
SimWalk PRO integrates predefined passenger profiles, delivering easy definition and simulation of passenger types
In addition, optional „Pedestrian Database“ modul includes data, formulas and tables of the most important research studies in pedestrian simulation of the last 20 years

8. STEP 3: Conducting simulation experiments
Simulation studies may be conducted directly in different visualization modes or without visualization in faster batch mode
Integrated CAD-Tool SimDraw allows fast changes of simulation layouts between simulation experiments
Fast adaptation and change of passenger parameters (number, typ etc.) between simulation experiments

9. STEP 4: Analysis of simulation results
SimWalk simulation results are stored in Access database and can be analyzed using integrated analysis tools or with SQL queries
Numerical results may be exported to Excel or analyzed in any other statistics software.
Simulation results maybe visualized as tables, bar charts, videos or snapshots in 2D or 3D

10. 3. Features of analysis
Crowd densities (bottlenecks etc.)  Pedestrian speeds and delays  Transfer times and connections
Pedestrian counts & flow rates
 Layout / facility analyis / space utilization  Pedestrian paths and route choices
 Predefined Levels of Service
 Self-defined areas of analysis
 Object capacities (escalators, stairs, elevators etc.)
 Commercial footfall analysis
 Queuing time and process capacities

11. 4. Object based modeling
 Modeling with SimWalk is based on generic graphical objects that allow broad flexibility in creating new and using predefined objects
 For example, pedestrian paths are modeled with start-, wait and exit objects and connections or processors with stair, escalator, elevator, gates or turnstile objects
 Object properties can be adjusted based on „capacity“, „frequency“, „delay“, „speed reduction“ or „utilization time“.

12. 5. 3D visualization - 3D EASY mode
 SimWalk PRO 3D EASY delivers a fast and easy 3D visualization with predefined 3D world functionalities and simplified pedestrian 3D objects
 3D EASY allows efficient realization of 3D visualizations for a first 3D impression of simulation results

13. SimWalk PRO Full 3D mode +
 SimWalk FULL 3D visualization is based on the following 3 data sources:
1) 3D virtual worlds can be created with any 3D Software (e.g. 3ds max) and exported in VRML 97 format
2) Virtual humans are delivered with SimWalk PRO (or may be created in MD2 Format)
3) SimWalk PRO simulation results
 SimWalk 3D rendering engine integrates all the data for an impressive 3D visualization
