■ FY 2019 NILIM budget estimate request

Planning and Research Administration Department Planning Division, Administrative Coordination Department Planning and Coordination Division

In its budget estimate request for FY2019, the NILIM will request an
R&D budget for 17 tasks (amounting to 220 million yen), including
the following 5 new tasks (amounting to 70 million yen) in the 4
important fields of “Disaster prevention, disaster mitigation, andcrisis management”, “Infrastructure maintenance and management”, “Productivity mission”, and “Improvement of region creationand ease of living”.

Disaster prevention, disaster mitigation,and crisis management
Research regarding breach perception and prediction of actual state of flooding
for information transmission to facilitate evacuation/flood prevention - Aiming toachieve zero delays in escape
In order to achieve zero delays in escape, and with the aim of further
enhancing the provision of information/advice to municipalities, etc., we willdevelop a flood outbreak perception and real-time mapping system to perceive
breaches and provide information on the actual state of flood outbreak inaddition to information on river water levels that has conventionally beenavailable.
Development of technology to rapidly determine soundness of base buildingsthat have been struck by earthquakes - To quickly and accurately determine
whether government office buildings can be entered immediately afterearthquake
We will produce a manual for determining the soundness of buildings fromboth structural and non-structural perspectives in order to help building
managers, who are not necessarily architecture experts, to determine whether it
is possible immediately after an earthquake has struck to enter municipal
government office buildings, etc. that serve as response bases in times ofdisaster.

Productivity mission
Development of terminal congestion index to contribute to improved
punctuality of container ships - Aiming to ensure punctuality of global supply
chain
The punctuality of major container routes has been dropping dramatically due
to congestion at container terminals. By performing analysis of the state of use of
the world’s major container terminals using AIS data, and clarifying the terminals
where delays are likely to occur, we will make it possible for shippers to selectroutes that have excellent punctuality and this will also lead to improvement of
the management of Japan’s terminals.

Improvement of regional creation andease of living
Research regarding wide-area cooperation of city functions in provincial cities- Aiming to burden of citizens’ movement through wide-area cooperation
For provincial cities where there is severe depopulation, we will support theplanning of wide-area cooperation by ascertaining regional issues and creating
guidance for improvement policies from the perspective of movement(transportation) of citizens, which becomes an issue when carrying out wide-areacooperation to service by division the city functions that cannot be maintainedby municipalities alone.
Development of evaluation techniques for effective application of environmental
conservation technology in coastal areas - Visualization of values of ecosystemservices
We will develop evaluation techniques to contribute to effective application ofenvironmental conservation technology in coastal areas, making it possible totake into account the natural environment, social environment and regionalcharacteristics.

Road Traffic Department, Road Safety Division

The Facility for Testing Collisions between Actual Cars andProtective Fences, which had was no longer in use due to being in astate of disrepair, was overhauled with an increased maximum
vehicle weight of 25 tons, putting it among the top category
nation-wide.
Overhauling this facility has made it possible to test the performance ofprotective fences under the same conditions as the design vehicle load of 25tons established in the Road Structure Ordinance (collision testing in theprevious facility was carried out with a gross vehicle weight of 20 tons). Since thetime of the PWRI, the predecessor to the NILIM, this facility has been used toconduct many collision tests in order to establish technical standards andspecification documents for protective fences. This facility has been used not
only by the NILIM, but also for many experiments for the development andimprovement of protective fences by road managers and protective fence
manufacturers. Going forwards, it is hoped that the use of this facility will lead todevelopment of protective fences contributing to further improvement of safetyof road traffic, such as with protective fences for high-standard roads including
temporary two-lane roads and community roads, etc.

■ Support for real-time flood prediction and operation of sewage facilities,and citizens’ countermeasure activities

The NILIM has formulated draft guidelines for introduction oftechnology to reduce flood damage in urban areas, which has been
occurring frequently in recent years due to sudden downpours, etc.
This technology predicts rainfall and analyzes outflow in real-time based on radarrain gauge and water gauge information, and provides facility managers andcitizens with flood information based on predicted sewer pipe water level andinternal waters. In this way, the technology makes it possible to reduce flood
damage by effectively operating existing flood countermeasure facilities such as
rainwater collection pipes, etc., and promotes citizens’ self-help/cooperation
activities. Since FY2015, the NILIM has implemented experimental research relating
to this technology in Fukui City and Toyama City under the Breakthrough by
Dynamic Approach in Sewage High Technology Project (B-DASH Project). In theexperimental research, preliminary calculations were made of the difference inflood damage between cases where the current operating methods are used inrelation to drainage pumps of rainwater collection pipes, and cases whereoperation was based on information transmitted using this technology.
As a result, it was confirmed that a reduction of flood area of approximately 19%
could be anticipated for rainfall with an annual exceedance probability of around in the target area. Also, from citizen questionnaire surveys, etc., we learned that theintroduction of this technology could be expected to promote
self-help/cooperation activities to a greater extent than prior to its introduction.
These results have been compiled and the “Draft guideline for introduction of
rainfall management technology for local downpours in city areas” has beenformulated. It is hoped that the introduction of this technology will reduce theflood disasters in urban areas that have been occurring frequently in recent years.

Housing Department, Research Coordinator for Housing Performance

The NILIM has published research results with technical explanation of residential planning techniques with consideration for child-rearing safety, comfort andease of living, as a draft guideline for households that are considering raisingchildren.
Households that are hoping to have and raise children want to enjoy housing where they can livewith peace of mind. To that end, this draft guideline was created for the spread of housing withfunctions/specifications, etc. that are ideal for raising children in safety and comfort.
The draft guideline is based on the assumption that it will be used as technical information whenbusinesses plan/design housing supply or when standards are created for national/municipal
support systems. To make it easy for these users to apply, the draft guideline has been created withthe following points in mind:① Explanation of items for consideration in planning and standards required inperformance/specifications, etc. of each item respectively for housing (private/shared areas), sites,
location environment, community, and child-rearing support services.
② Explanation of priority of items for consideration in terms of requirements/recommendations,etc. for each type of housing, including ownership, ways of building, new construction and existing
housing, etc.
Going forwards, we will endeavor to spread the draft guideline.

■ “4th Investigative Committee Meeting for Plans to Reduce High Tide Risk in

Waterside Land, etc.” was held

Coastal, Marine and Disaster Prevention Department, Coastal Disaster Prevention Division

Together with holding the “4th Investigative Committee
Meeting for Plans to Reduce High Tide Risk in Waterside
Land, etc.”, we published the “Guideline for plans to reducehigh tide risk in waterside land, etc.”

Guideline for for plans to reduce hightide risk in harbor, waterside land, etc.

In Japan’s harbors, distribution functions and companies areconcentrated in so-called waterside land on the sea side from coastpreservation facilities, and in Japan’s three main bays forming the coreof economic activities, at least 80% of harbor-facing areas arewaterside land.
At the Bureau of Port and Harbor, an “Investigative Committee
Meeting for Plans to Reduce Storm Surge Risk in Harborside Land, etc.”
consisting of experts was established due to the possibility ofsignificant congestion of Japan’s harbor distribution networks and theproduction activities of location-selecting companies due to flood
damage caused by high tides, and this Investigative Committee
Meeting has been considering high tide countermeasures.
At its 4th and final meeting, deliberation was carried out with theaim of compiling guidelines, the results of which were published by
the Bureau of Port and Harbor as a guideline consisting of a
“Phase-specific high tide response plan” detailing disaster prevention
activities to be taken in advance based on weather information, etc.,
such as evacuation of workers, etc. from harbor waterside land andmovement of freight to higher ground, etc., as well as an “Area disaster■March 2018

prevention plan” to be taken concerning necessary hard and soft policies in cooperation withthe relevant parties for installing surveillance cameras and taking measures to stop water fromgetting into warehouses and electrical facilities, etc. in areas where there is significant damage.
Going forwards, the NILIM too will provide necessary technical support for high tide
countermeasure initiatives in harbors based on this guideline.
