Pedestrian and Evacuation Dynamics PED 2012 (2012)


 Since many years the RiMEA-Richtlinie (Richtlinie für Mikroskopische Evakuierungs Analysen - Guideline for Microscopic Evacuation Analyses; RiMEA-Guideline) is a guideline for German-speaking authorities to check evacuation analyses of complex buildings. Based on the RiMEA-Guideline expert reports are written to ensure that the fundamental questions of an evacuation analysis are answered.

Since November 22nd, 2011, a German DIN Specification (like a Pre-Standard) for evacuation calculations (DIN Spec 91284) is available. This DIN Specification is based on the RiMEA-Guideline and was developed together with the RiMEA society (RiMEA e.V.). The first part of this presentation will show how this DIN Specification (DIN Spec 91284) was developed and what kind of requirements have to be fulfilled to “transform” the RiMEA-Guideline to this German DIN Specification.
Additionally we will show what are the differences between this DIN Specification and the RiMEA-Guideline.
In an Annex the RiMEA-Guideline presents a set of test cases for microscopic software tools for evacuation calculation. This will be the second part of the presentation. These test cases should be used by the software developer to show results of the software by themselves, and to present results in a written report to e. g. local authorities for validation of the model used in the software and verfication of its correct implementation. These test cases are very basic, to ensure that any suitible software is able to run the test scenarios. The goal of these test cases is to show users of software tools the differences or equity of different software tools, furthermore these test cases should show local authorities that the software tools which have been used for an evacuation report fulfill at least this minimum standard for software tools. At the moment (November 2011) the RiMEA-Guideline consists of 14 test cases for software tools.
These test cases are combined to different groups of verification and validation test cases, thus we have
- Test cases for different software components (test case 1 – 7)
- Functional verification/validation (test case 8)
- Qualitative verification/validation (test case 9 - 14)
In the following we present a short overview about these test cases:
- Test case 1: Keep velocity in a floor
- Test case 2: Keep velocity upstairs
- Test case 3: Keep velocity downstairs
- Test case 4: Specific flow through an opening
- Test case 5: Response time
- Test case 6: Moving around a corner
- Test case 7: Assignment of demographic parameter
- Test case 8: Parameter study
- Test case 9: Evacuation of a large room
- Test case 10: Assignment of evacuation routes
- Test case 11: Choosing an evacuation route
- Test case 12: Effects based on bottlenecks
- Test case 13: Congestion in front of stairs
- Test case 14: Route choice
In this part of the presentation we will show results of different software tools based on the test cases, which are part of the RiMEA-Guideline. The goal of this part of the presentation is also to assure developers of international non-German software tools to use this kind of verification/validation suite to show the capabilities of their software tools. Furthermore we would like to invite everybody to submit new test cases for the RiMEA-Guideline, thus the number of test cases will increase, thus at the end a wide an well accepted „benchmark suite“ can be presented to users of software tools for evacuation calculation and to local authorities, which have to accept results which are calculated by these software tools.
In the last part of the presentation we will show how the RiMEA guideline was developed over several years. Therefore we will give an historical overview about the development of the RiMEA guideline, which was first presented at PED 2005 in Vienna to an international audience. Based on the first version of the RiMEA-Guideline (January 2004) and the actual edition, which will be adopted at the RiMEA member meeting in March 2012 we will show how the guideline grows (18 pages 2004, actually 32 pages 2011) and what changes have been done. We furthermore want to show how a new version of the RiMEA-Guideline is developed and what are the further plans of RiMEA e. V., the society which is responsible for this Guideline.
