Systematic Transportation of Logistics for East Japan Great Earthquake 2011

1. Systematic Transportation of Logistics for East Japan Great Earthquake 2011 Anthony Kenta Homma Ryo Miyasaka Yuki Takada 1

2. Tsunami disaster

3. 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.

4. 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.

5. General Analysis of Common Transportation Means

7. Cases of area attacked by tsunami refuge rubble crevice port port port

8. Current solution for the case LCAC (amphibious hovercraft) Hovercraft as an alternative solution for port closure Limited coverage; land route is still much needed

9. 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

10. 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

11. 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

12. 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

13. 2)Avoiding the rubble 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

14. Suggestion Introduce “road checking system” Measure road’s accessibility according to the state of the road using satellite photographs. ⇒

15. Suggestion • 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

16. 3)Ignore or break through rubbles 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

18. 4)Removal of rubble and road repair Eventually we need to remove rubbles and repair the roads to recover the ordinary traffic

19. Suggestion 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

20. Merits and demerits of each means

21. Choice of means available Earthquake ↓ unavailable

22. 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
