All these tests are described in more details in this [article](http://www.rimea.de/fileadmin/files/dok/richtlinien/r2.2.1.pdf).
|
|
|
The notes give hints about specific implementation in JuPedSim.

***
|
|
|
|
|
|
- **Test 1**: One pedestrian is moving along a corridor.
|
|
|
|
|
|
Test if pedestrian can maintain its speed constant
|
|
|
|
|
|
- **Test 2**: One pedestrian moving on a 10m long stair.
|
|
|
|
|
|
It should be shown that the pedestrian can maintain its speed constant.
|
|
|
|
|
|
- **Test 3**: One pedestrian moving on a 10m long stair **downstairs**.
|
|
|
|
|
|
It should be shown that the pedestrian can maintain its speed constant.
|
|
|
|
|
|
- **Test 4**: Show that the model can produce the shape of the fundamental diagram (density-velocity relation)
|
|
|
in a simplified one-dimentional corridor with closed boundary conditions.
|
|
|
|
|
|
- **Test 5**: Distribute 10 pedestrians with 10 different reaction times.
|
|
|
|
|
|
Verify whether they start exactly at the specified times.
|
|
|
|
|
|
- **Test 6**: 20 pedestrians going around a corner.
|
|
|
|
|
|
Pedestrians should not cross walls.
|
|
|
|
|
|
- **Test 7**: Distribute pedestrian's speed according to the Table in Page 6. Four different groups are distributed according to their velocity:
|
|
|
1. \(v<30\)
|
|
|
2. \(30<v<50\)
|
|
|
3. \(v>50\)
|
|
|
4. handicapped.
|
|
|
|
|
|
Verify whether the speed values are within the specified range.
|
|
|
|
|
|
- **Test 8**: A 3D building is simulated and the influence of parameter e.g. speed
|
|
|
is investigated.
|
|
|
|
|
|
It should be shown how the evacuation time behaves with respect
|
|
|
to the investigated parameter. [^rimeaNote1]
|
|
|
|
|
|
|
|
|
- **Test 9**: 1000 pedestrians are distributed in a room with 4 exits.
|
|
|
- scenario 1: All 4 exits are open
|
|
|
- scenario 2: 2 exits are closed. The remaining 2 are still open
|
|
|
|
|
|
The flow should nearly be doubled in scenario 1. [^rimeaNote2]
|
|
|
|
|
|
- **Test 10**: Pedestrians are distributed in 12 different rooms. The building has two exits.
|
|
|
|
|
|
The Pedestrians have exactly assigned exit numbers and should evacuate through these. [^rimeaNote3]
|
|
|
|
|
|
- **Test 11**: 300 pedestrians are distributed in a room with two exits.
|
|
|
|
|
|
The pedestrians should prefer the nearest exit, but some should (spontaneously) choose the second exit.
|
|
|
|
|
|
- **Test 12**: Two bottlenecks are connected with a long corridor.
|
|
|
|
|
|
At the last exit there should be no jam. [^rimeaNote4]
|
|
|
|
|
|
- **Test 13**: Pedestrian coming out from a bottleneck along a corridor. At the end of the corridor is a stair.
|
|
|
|
|
|
Since pedestrians have to reduce their speed on the stair, a jam should be observed at the beginning of the stair.
|
|
|
|
|
|
In case of jam, flow at the beginning of the stair should be smaller than the flow in the corridor.[^rimeaNote5]
|
|
|
|
|
|
- **Test 14**: Pedestrian's evacuation to an exit. Pedestrians have two possible routes:
|
|
|
- short
|
|
|
- and long
|
|
|
|
|
|
This test has no concrete condition to check for.
|
|
|
It should be documented whether pedestrians take a long detour or not
|
|
|
There are 4 stats that should be documented:
|
|
|
|
|
|
1. "kurz" (*short*)
|
|
|
2. "lang" (*long*)
|
|
|
3. "gemischt" (*mixed*)
|
|
|
4. "konfigurierbar" (*configurable*)
|
|
|
|
|
|

|
|
|
[^rimeaNote1]: This is not a fail criterion. It is just for documentation purposes.
|
|
|
|
|
|
[^rimeaNote2]: For simplicity in JuPedSim we simulate two identical rooms:
|
|
|
- room left: with 4 exits. All of them are open
|
|
|
- room right with 4 exits. two of them are closed
|
|
|
- We write the trajectory in plain txt-format, to avoid a long lasting xml-parsing
|
|
|
|
|
|
[^rimeaNote3]: Pedestrian are assigned to two different groups. We verify if pedestrians in the two groups pass the exits.
|
|
|
In the simulation pedestrians disappear once they are outside therefore we check if a pedestrian goes through line `exit - displacement`.
|
|
|
|
|
|
[^rimeaNote4]: The condition of this test is not clear enough...
|
|
|
In the last exit there should be no jam, which means $$J_{bottleneck} >= J_{last}.$$
|
|
|
However, this condition is not enough to quantify a jam.
|
|
|
|
|
|
[^rimeaNote5]: The reduced speed on stairs (up) is according to Tab 1 in [Burghardt2014][#Burghardt2014].

|
|----------|----------------|
|
|
|
| PM | 0.63 m/s |
|
|
|
| WM | 0.61 m/s |
|
|
|
| NM | 0.8 m/s |
|
|
|
| FM | 0.55 m/s |
|
|
|
|
|
|
|
|
|
|
|
|
Therefore, we choose for $$v^0_{upstairs}$$ a Gauss-distribution with $$\mu = 0.675$$ and $$\sigma = 0.04$$.
