Systematic Transportation of Logistics for East Japan Great Earthquake 2011

1

Tsunami disaster

2

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.

3

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

6

Cases of area attacked by tsunami

7

port port port

refuge

crevice

rubble

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

9

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

10

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

12

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

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

4)Removal of rubble and road repair

18

Eventually we need to remove rubbles and repair the roads to recover the ordinary traffic

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
