When the accident and fire occur in the long tunnel, it is very important
for the tunnel management staff to provide the evacuation order in the
appropriate timing.
Any judgmental errors in fire evacuation may involve human lives and should
not be condoned.
For example, the fire accident of truck that occurred in Montblanc tunnel,
France, 1999 killed 39 lives.
It is because the tunnel manager gave inappropriate orders in the evacuation
process.
Realistic representation by simulator "UC-win/Road" for the accident
training |
It is important for the tunnel managers to prepare and assume the situation
to provide the order in a calm and reassuring manner while judging the
current condition when the accident occurs.
BMIA, Bordeaux in France recreated a variety types of accident with the
virtual reality (VR) technology, and developed the training system "G'VAL
Training System) for the preparation of their judgement, order, and counter
measure.
The function is very realistic and we can say it is the tunnel version
of flight simulator which is used for the training of pilot.
In front of the tunnel manager "Trainee", the movie of television
camera installed in the tunnel, SCADA screen which represents the operating
condition such as ventilation fan and electric bulletin board, and monitor
which represents the alarm screen from alarm equipment are installed.
These screens are connected to G'VAL system, and the contents which are
similar to the actual tunnel management system can be realistically represented
by UC-win/Road.
The trainer "instructor" creates the scenario of accident by
combining the accident contents including fire and clash under the condition
of weather, time, traffic amount, and speed. This is provided to the trainee
via G'VAL system as the "Task" for the training.

Behavior of trainee is registered to output the evaluation report |
For example, the instructor sets up the accident scenario where the vehicle
is broken and stops in the tunnel, and the fire occurs, and he/she runs
this scenario in G'VAL system.
In the monitor camera of trainee, the situation is displayed, and the fire
alarm is activated. And this is the time the trainee can show their skill.
They need to take measures from moment to moment by checking the current
condition with the monitor screen and SCADA, and alarm; the order of traffic
control, rescue team, and smoke ventilation.
And then, the patrol car and fire engine entering the tunnel based on the
order are displayed in the monitoring camera at the entrance of tunnel,
and the scene where these vehicles arrive at the accident site late is
displayed in the camera near the site. To experience the feeling of lapsed
time is one of the important training elements.
Depending on the location and size of fire, they may need to turn the traffic
lights at the tunnel entrance to red to prevent the entry of other vehicles,
and order the drivers in the tunnel to follow the evacuation path with
electric signboard.
The action and judgment of trainee are registered with the monitor camera
and SCADA data, and the evaluation report is output. In other words, we
can verify and review if their judgment was appropriate and if there is
anything to be improved after the training.
Actually, when the accident happened, we cannot turn back the clock even
we think "If I could do different way..". However, with this
training program, we can learn from the G'VAL system result to do different
way. This is the main merit of this program.
The repeated training assuming the various scenarios will foster the high-skilled
tunnel administrators who can perform an action without the pressure in
the event of an emergency.
BMIA has this G'VAL system of demonstration equipment which is connected
with 6 monitors and 3 computers.

High-evaluation for the software development kit for the linkage of UC-win/Road
with the original system |
Mr. Philippe Marsaud, technical director of BMIA comes from Bordeaux. He
studied in the engineering school in Paris, and has worked as an engineer
of oil development, robotics, and automation.
He has developed the tunnel integrated management system "SCADA (Supervisory
Control And Data Acquisition)" for seven years since he started his
own business in Paris as a consultant of tunnel in 1999.
After that, Mr. Philippe Marsaud decided to create the simulation system
of tunnel. The new company which was established with his wife in Bordeaux
is BMIA.
Mr. Marsaud mentioned the reason as "There was no available tunnel
simulation system in the market at that time".
Currently, BMIA carries out two types of business. One is the consulting
business, and they provide the training of SCADA system. Another is the
software development business. They have developed some software: "G'Tun"-Tunnel
simulator, "G'Road"-Road simulator, "Sofaex"-The order,
action, telephone of tunnel manager are recorded, and "Genesuite"-Project
management software.
G'Tun and G'Road allow the simulation of electric bulletin board, lane
closure, obstacles, camera, repeater indicator, traffic signal, emergency
light, tunnel light.
It creates the data including traffic stream, accident, ventilation fan,
exhaust gas, ventilation condition, door movement, emergency call, and
fire extinguisher.
G'VAL systems allow the visualization of the data created by this simulation
system based on scenario using SCADA and UC-win/Road.
The scenario includes the slow-speed vehicle, broken vehicle, accident,
smoke, obstacle such as burden and wheel, rescue team and workers, patrol
car, police, and walking animals.
Mr. Marsaud commented "It has been just seven months since I started
to use UC-win/Road, but I like the system linkage function with other system
using system development kit. It is very ideal software for me." "For
people's evacuation simulation, I think to use the crowd analysis software
"EXODUS" in the future."

Expectation of the world first system, practical use for a wide range of
issues such as traffic congestion |
The scope of this G'VAL system which is introduced this time can be thought
to include a wider range of fields including train tunnel, road network
in the urban area as well as road tunnel.
For example, the traffic administrator in the urban area can use it for
the training of traffic signal control and lane closure so that the traffic
congestion is reduced. According to BMIA, G'VAL system is the first training
system using virtual reality in the world.
Therefore, there is the expectation of this system from US where people
are suffering from the traffic congestion.
Brendan P Hafferty, general manager of FORUM8 western office in UK and
Yoann Pencreach, FORUM8 VR development technical manager in Miyazaki office
have contributed to the development of this system through the technical
support and the provision of the related information.
Mr. Marsaud was satisfied as he could obtain the effective information
available for the development of new product through the FORUM8's support
and network provided by the installation of UC-win/Road.
As for the request of the enhancement of UC-win/Road, he requested that
the number of places to be recorded would be increased so that the movie
from many monitoring camera can be recorded.
The cooperative relationship with BMIA would be very important for FORUM8.
Through the development of the world's first training system for the tunnel
administrator and road administrator using virtual reality, we will be
able to know what kind of product the end users need, and apply this information
for the development of products with the latest market trend.
