spills. Landslides. Tornadoes. Plane crashes. Pile-ups. Floods. These
are just a few of the emergencies and disasters that could occurand
have occurredin Pittsburgh. When the call comes in, emergency
management teams of Allegheny County respond. However, most calls
come from bystanders who rarely can give the details needed to plan
the correct response. Researchers at the University of Pittsburgh
are developing a system that will allow emergency managers in Allegheny
County to make timely and better planned responses.
The system,
a Secure Critical Information Technology Infrastructure (S-CITI) for
Emergency Management, will integrate incoming real-time data from
cameras and sensors and signal when data deviates from normal activity.
Funded
by a $2.8 million grant from the National Science Foundation, S-CITI
will be the first of its kind to simultaneously integrate data from
multiple sources, and be applicable to all cities. Cities such as
Los Angeles have earthquake detectors connected to emergency managers,
but no city has a comprehensive system where data from utilities,
the National Weather Service, and traffic sensors are integrated in
real time.
Currently,
emergency information is correlated in someones head. We want
to make it much more automated and efficient, said Daniel Mossé,
associate professor in Pitts Department of Computer Science
and principal investigator for S-CITI.
Already
deployed electricity, gas, water, and temperature sensors as well
as traffic cameras will be utilized, and new sensors will be added.
For example, stationary cameras that monitor traffic could be replaced
with rotating cameras that take pictures in the case of a landslide.
Mossé
and his team are working closely with the Chief of Allegheny Countys
Department of Emergency Services, Robert Full, who has endorsed the
project. Talks are underway to evaluate the needs of the countys
emergency managers, identify security concerns, and discuss how S-CITI
can best accommodate the county.
The
computer scientists will identify the most appropriate ways to represent
the information, integrate it, and merge it without revealing anyones
secrets, but still be able to develop coordinated action for multiple
organizations in emergency situations, said Louise Comfort,
co-principal investigator and professor in Pitts Graduate School
for Public and International Affairs.
Security
is quintessentially important, said Comfort. Allegheny County has
130 municipalities, each with its own secure information. In order
for a central system to be implemented, each jurisdiction must consent
voluntarily to release its information. Mossé envisions a system
that uses the information without releasing it, except in an emergency
when the data is needed to coordinate a response.
Computers
can marshall all kinds of complex and diverse information, which can
be presented to the decision-makers in a clear, logical, and timely
way. This will assist the emergency managers enormously, said
Comfort. They need to be able to review the information in a
way thats easily comprehensible, then make a decision.
A critical
piece of the system will be a learning module, which will analyze
postemergency data and use the results for future pre-emergency planning.
For example, explained Mossé, if one day the system detects
much higher than normal usage of gas and water and lower than normal
usage of electricity, it will alert emergency managers.
Maybe
there was an earthquake or a landslide and some electricity poles
were downed and some water pipes and gas lines were broken,
said Mossé. However, the emergency managers may say this
is a normal situation on Thursday afternoons because people barbeque
and fill up their pools, and they turn off the lights in their house
because theyre outside.
If the
change in sensor activity is not an emergency situation, the emergency
managers will be able to program the system to ignore the signals
on Thursday afternoon. The system will learn to alert the mangers
only in actual emergency situations, saving time and labor.
The system
could be useful in detecting such potential security threats as harmful
materials entering the city on trucks coming through the tunnels.
It also could alert emergency managers when information is not coming
in that should be coming in, such as when power lines go down.
Were
beginning to be able to address very complex problems that we couldnt
imagine addressing before because it would have been too hard,
said Comfort.
Mossés
team will spend the first few years of the S-CITI project building
a prototype of the system within the Department of Computer Science
and then within part of the University. Potentially, the system will
have direct links with the Pitt Police. When the system is sufficient,
it will be deployed in parts of the city, and Mossé and Comfort
eventually would like to see it used extensively in Allegheny County.
