De verkeersleider kan weggebruikers in een tunnel aansturen met omroepberichten. De berichten worden van tevoren opgenomen met studiokwaliteit, en vervolgens met één druk op de knop afgespeeld. Automobilisten zullen zo’n bericht eerder begrijpen; en ook neemt de werkbelasting van de verkeersleider af, hetgeen de veiligheid vooral bevordert bij...

Motorists drive through tunnels at high speeds. In consequence, they see the tunnel in a flash and have no idea how the tunnel looks like when they have to walk in the tunnel, for example, when evacuation is required. The authorities responsible for evacuation (and escape signs) are experts who fail to see the tunnel the way the general public...

Auditory evacuation beacons can be used to guide people to safe exits, even when vision is totally obscured by smoke. Conventional beacons make use of modulated noise signals. Controlled evacuation experiments show that such signals require explicit instructions and are often misunderstood. A new signal was designed that combines a chime sound...

Fire and smoke in a tunnel are dangerous because people get disoriented, blinded, and finally suffocate. When such a situation occurs (despite all precaution), sound beacons over the emergency exits could be a great help, reducing escape time through smoke. We let human participants "find refuge" from a road tunnel in dense (cosmetic) smoke....

Eerdere proeven van TNO hebben aangetoond dat geluidbakens boven de vluchtdeuren de automobilisten helpen om te voet te vluchten uit een tunnel, ook in dichte rook. Om deze geluidbakens in tunnels aan te brengen heeft Rijkswaterstaat Bouwdienst aan TNO gevraagd het aanbestedingstraject te ondersteunen.De opdrachtverlening kent twee fasen: eerst...

Purpose: Safe and timely evacuation of metro station Rokin, Amsterdam--is that possible using the escalators in case of a power loss? Commissioned by the municipality of Amsterdam, service Infrastructure Traffic and Transportation, TNO measured the actual evacuation capacity of a stationary escalator in relation to the evacuation capacity of the...

As a test on auditory guidance, participants tried to .nd refuge and safety in a road tunnel in dense smoke with sound beacons over the escape exits. The beacons emitted a 'shhussing' noise with a 5-Hz pulse frequency. Three groups participated, 32 or 33 participants per group, the first with minimal instruction (sound not mentioned), the second...

GVB Amsterdam organiseerde een praktijkproef met in- en uitstappende figuranten. Een fiets meenemen kost 6-7s extra tijd bij de halte. Bij ontruiming niet veel extra.

Automobilisten zijn amper bereid hun auto te verlaten als ze in een tunnel in een file staan en voor hen is brand. Een 'commando' is nodig, daarna helpt het kudde-effect.

When disaster strikes, mass transportation means mass evacuation. The issue is especially urgent if, despite precautions, a train comes to a stop in a tunnel and there is a fire. Adequate behaviour of passengers is a major success factor of an evacuation. Passengers should replace their original (travel) goal with the evacuation goal and--once...

Purpose: Escape from a burning tunnel in dense smoke: Can that be done when sound beacons over the emergency exits assist people in escaping? A concept developed and tested in the UK claims 90% success but when we tested the beacons in a tunnel in The Netherlands without telling the participants about beacons over the exits, the success was a...

Purpose: Can people lost in dense smoke be guided by sound? In a previous test with (commercially available) sound beacons over the emergency exits of a tunnel barely 20% found the exits; "unacceptable" according to the Centre for Tunnel Safety of the Civil Engineering Division of the Directorate-General for Public Works and Water Management....

Vanwege maatschappelijke verontrusting over de veiligheid van autotunnels gaf de Bouwdienst van Rijkswaterstaat opdracht na te gaan wat de gemiddelde weggebruiker weet van de in tunnels aanwezige noodvoorzieningen. De opdracht is deel van een groter geheel van proeven met gecontroleerde branden, gesimuleerde evacuaties en hulpdiensten. TNO...
