Lessons learned from post-disaster conditions after major urban earthquakes are
used to develop roadway management strategies for other man-made or natural
Events considered are those which cause major disruptions to the
roadway network but would not necessarily require evacuation of the population.
These include terrorist attacks, earthquakes, tornadoes, widespread flooding, etc.
Events such as nuclear or chemical incidents or approaching hurricanes, which
require evacuation of communities, are not considered.
Key management functions of an Emergency Operations Center such as
damage inventory and detour plans are addressed.
The main objectives are to
mitigate the impact of such disasters on the population while accelerating the
return to normalcy.
The findings are incorporated into a GIS decision tool which
allows editing of the roadway network to reflect roadway closures and capacity
The updated network information is then used to determine optimal
traffic detour and diversion strategies to best utilize the remaining network
post-earthquake, post-disasters, urban transportation network,
roadway network, traffic mitigation, emergency operations centers.
Earthquake hazard mitigation strategies have traditionally overlooked the
importance of transportation in mitigation and post-earthquake recovery efforts.
The 1985 Mexico City earthquake  clearly indicated that the planning and
post-earthquake operational management of an urban transportation network
must be an integral part of any urban earthquake preparedness plan.
