Research study on the cargo transportation with cross-sectional mode in case of a wide area disaster(Report No.131)
Summary
When the wide-area disaster occurs, such as Nankai Trough giant earthquake,
it is extremely important not only to maintain transportation of relief
supplies in emergency and recovery phase, but also to restore general logistics
to normal for the social economic activities.
As simulating the situation of Nankai Trough giant earthquake, it is found
the following issues would take long period: "Long-term East-West
division by the disaster of Chubu District", "Cutoff of the traffic
between Honshu and Shikoku by the disaster of the Honshu-Shikoku Bridge”
“Cutoff of the cargo railways in the Chugoku district without detour routes".
Including these issues, we inspected the impact on the logistics and found
it is considered that the transport demands extremely decrease in many
OD (Origin- Destination), and on the other hand, physical cutoff of the
traffic networks and lack of resources generate cancellations of transportation,
and large traffic jams happen in the detour routes.
On receiving this result, we made the following three scenarios and carried
out the simulations and inspected the effects: “Taking measures to the
roads with early restoration in Chuo Expressway ? Meishin Expressway -
Chugoku Expressway”, “Taking measures to the railroads with early restoration
in Gifu - Nagoya - Kasugai and temporarily to use the San-in line as cargo
transportation”, “Raising regional procurement rate of auto parts nationwide”.
As a result, it is considered that all of them are effective and the importance
of prior measures are suggested.
For preparing against Nankai Trough giant earthquake it is necessary to
examine the way of the logistics after disasters at a nation level. However
the discussions and investigations with the wide variety of shipper companies
or traffic-related business people is assumed to have difficulties. Therefore
the country and local government will be required to discuss in cooperation
with people in various quarters, and to lead to establish the direction
of policies on both of hardware-software and examine the concrete measures.
