Background
Severe earthquake and Tsunami causing destruction of epic scale in Japan on March 11th
Shortage of logistics such as foods, fuel, and blankets was one of the most urgent and serious problems
Transport of supplies to areas affected by earthquake and tsunami was hampered because of traffic isolation.

Issues
Need to deliver relief supply to the affected areas within the shortest time frame
Need to find the solution to access the affected areas
Re-consider the most suitable choice of transportation means according to the situation and the demand of evacuation spots.

General Analysis of Common Transportation Means

Cases of area attacked by tsunami
7
port port port
refuge
crevice
rubble
![Page 8: Systematic Transportation of Logistics for East Japan Great Earthquake 2011](https://reader035.fdocuments.in/reader035/viewer/2022062221/5681455e550346895db23031/html5/thumbnails/8.jpg)
Current solution for the case
Hovercraft as an alternative solution for port closure
Limited coverage; land route is still much needed
8
LCAC(amphibious hovercraft)

Issues of Land Transport
Indispensable Land transport is still required as the connection between evacuation
spots and ports
Need to be recovered as soon as possible Most of supply will be transported through the land route because it is
affordable and quite adaptables
Have many troubles Roads and rails are most vulnerable to destruction by earthquake and
tsunami

Solution for road separation
Piled rubble or wide crevice separates the road to the destination
How we can get to the destination?
Prevention Avoidance Breakthrough Removal

1)Prevention of piling rubbles
Before the trouble attack the road, prevention can be done
Such prevention of piling on the road traffic enable smooth mobility
11

Suggestion Build road on higher places like banks
In 3.11 case, “Sendai East Road”
had played roles as places
evacuation area and
embankment, saving about
230 people Applying the construction of such
roads to other coastal areas
Build embankment along the main road defend roads from tsunami and piling of rubbles also reduce noises from traffics

2)Avoiding the rubble
13
If there is another safe road, we can choose that route as the alternative.
The problem lies on how can we locate the safe route
![Page 14: Systematic Transportation of Logistics for East Japan Great Earthquake 2011](https://reader035.fdocuments.in/reader035/viewer/2022062221/5681455e550346895db23031/html5/thumbnails/14.jpg)
Suggestion Introduce “road checking system”Measure road’s accessibility according to the state of the road using
satellite photographs.

Suggestion
15
Observer categorizes the damage of all roads when the disaster occurred, illustrated in the table below
If satellites can categorize automatically it costs so little time to decide the best route

3)Ignore or break through rubbles
16
Means to break through the rubbles or ignore them

17
Suggestion Huge vehicle with big tires or caterpillar as means to get
over the rubbles
Smaller-sized vehicle can be used
to deliver supply
Legged robots for transportation is another plausible solutions
huge dump truck
four-legged robot
![Page 18: Systematic Transportation of Logistics for East Japan Great Earthquake 2011](https://reader035.fdocuments.in/reader035/viewer/2022062221/5681455e550346895db23031/html5/thumbnails/18.jpg)
4)Removal of rubble and road repair
18
Eventually we need to remove rubbles and repair the roads to recover the ordinary traffic
![Page 19: Systematic Transportation of Logistics for East Japan Great Earthquake 2011](https://reader035.fdocuments.in/reader035/viewer/2022062221/5681455e550346895db23031/html5/thumbnails/19.jpg)
According to the categorization of road’s damage, we can decide the priority in repair
Less-damaged roads with higher number of traffic should be repaired

Summary
We have to choose transport means according to the condition of affected area
In any case, land route is most important to deliver supply Multi-sided measures are considered as the solution for the
road separation Need to combine all these measures in response to the
situation
