Test 6: Movement around a corner

1. Definition

Twenty persons, spread uniformly over a start area 6 m long, walk towards a corner that turns left. A corridor 10 m long and 2 m wide ends in a turn into an arm 2 m wide and 10 m long. The persons go around the corner without passing through walls.

Scenario figure from the executed notebook.

3. What to expect

All 20 persons go around the corner without passing through a wall. RiMEA states this as a yes/no outcome and sets no further pass limit (p. 28).

Our criterion: Navigate a corner; agent bodies do not overlap a wall (centre at least radius - 1 mm from walls)

4. Our result

Status: PASS

Test cases of this row

• test_agents_stay_in_geometry: bound: 0 <= measured <= 0 (samples outside the walkable area)

5. Our implementation

Deviations from the standard:

• The vertical arm runs 8 m above the corridor and nothing below it, and the start area is 4 m long. Fig. 6 labels a 10 m arm above the corridor and a start area 6 m long.
• The pass rule is the suite’s own: all 20 agents evacuate, and on every sample each agent’s centre stays at least its radius, less 1 mm, inside the walkable polygon, so a body overlapping the inner corner fails (decision D16).
• Agents have a constant desired speed (1.0 m/s) and the default radius of 0.15 m. RiMEA’s text asks for no speed.
