River administration facilities such as levees and river walls play a major role in preventing flooding due to heavy rain. The forms of such facilities must be constantly monitored for alteration due to rain and running water, and limited human resources and budgets make it necessary to efficiently maintain river administration facilities. During maintenance, inspection results are commonly recorded on paper documents. Continuous inspection and repair using information systems are an on-going challenge. This study proposes a maintenance management system for river facilities that uses three-dimensional data to solve these problems and make operation and maintenance more efficient. The system uses three-dimensional data to visualize river facility deformation and its process, and it has functions that visualize information about river management at any point in the three-dimensional data. The threedimensional data is generated by photogrammetry using a camera on an Unmanned Aerial Vehicle.

Maintenance management is an essential operation that should be carried out effectively for maintaining, repairing, and rehabilitating highways and roads. In road maintenance site, the administrators and engineers want to refer and utilize the road ledger and its drawings. It is difficult to carry and use the ledgers and documents, because they are paper based documents. The primary objective of this study is to solve above problems on road maintenance and maintain the road efficiency. This paper proposed a road inspection support system using AR marker and QR code. The system consists of two functions: the function that AR marker indicates an important inspection point on site and the reference function of inspection and rehabilitation data using QR code. AR marker was used for indicating important inspection points of main girder, crossbeam, and drainage on bridge. QR codes were attached on kilo post at one hundred meter intervals. The inspectors can refer the inspection data of pavement, slope, directional arrow, and sign. And, the product data models were developed, which systematic information is defined for accumulating, exchanging, and sharing in civil infrastructure. The proposed system was evaluated the usability and capability in Shiraito Highland Way in Nagano Prefecture, Japan. The evaluation results indicated usability and capability on site usage. In the future work, the system will use and manage the daily inspection and rehabilitation data.

Roads are networks that connect social infrastructure and accommodate the delivery of emergency services. Because of the importance of roads, they should be safe and kept in good condition. To perform effective road management, the use of spatial and temporal information is necessary. Maintenance management is an essential operation that should be carried out effectively for maintaining, repairing, and rehabilitating roads. It is necessary to accumulate information produced during the entire life cycle of a road in order to analyze problems and find solutions within a temporal sequence and to maintain roads strategically and effectively. In this paper, four-dimensional information is defined as the combination of three-dimensional spatial information and temporal information. Four-dimensional information is required for storing the historical information of road condition. This paper proposes a four-dimensional information management system to collect, accumulate, share, and utilize four-dimensional information. The system consists of a spatial data infrastructure, road data models, a model library, a common system interface, common functions, a road database, and a road application system. The road application system provides functions for simulation, progress management, and the representation of four-dimensional information. The system is demonstrated using actual data on road maintenance. It is verified that the system has the capability to be applied in practice. (C) 2013 American Society of Civil Engineers.

Rivers are managed by preparing materials including various drawings and registers. In particular, cross sections are very important materials because they are used for not only grasping the current conditions of levees but also river improvement plans and so on. However, since cross sections are surveyed and made into drawings by human operation, they are created only on the distant posts at 200m intervals due to limitations of survey costs. Currently, therefore, a technology for generating cross sections from LP data acquired by airborne laser surveying is needed. However, there are some problems for LP data ; that they contain noises of vegetation and so on which disturb ground surface survey, and that it is impossible to measure changing points of cross sections due to the problem of point cloud density. Existing researches on dealing with the problems for LP data include a method of extracting point cloud data of the ground surface by obtaining the lowest point at every specific range from LP data, and a method of estimating break lines from LP data. However, the former has "a problem that the accuracy of point cloud data is dependent on the grid width" and the latter "a problem that it makes an error in extraction of a break line at bends". To solve these two problems, this research proposes a method for noise reduction which is independent of grid width, and a method for estimating break lines properly at bends as well. In order to prove usefulness of the proposed methods, evaluation experiments were conducted to compare the cross sections of proposed methods with those of existing methods, and evaluated them.

A Civil infrastructure is built through the prolonged process of plan, investigation, design, construction, and operation and maintenance, and drawings are taken over in each process. Drawing data of structures are generated in a design phase using CAD (Computer Aided Design) software. The design intention of a structure like the use function of CAD software, and a model generation procedure is expressed in CAD data. Therefore, it can be necessary to use it in construction or operation and maintenance phase. Moreover, in a construction project, although building the environment where three-dimensional data is used for CIM (Construction Information Modeling), information integrated construction, and an improvement in productivity is requested, the three-dimensional CAD which fills these requests does not exist.<br>In this paper, the three-dimensional CAD engine for creating the three-dimensional CAD data holding the design intention of an infrastructure was developed. The three-dimensional CAD engine developed fulfills the needs concerning infrastructure, such as adoption of parametric modeling, consideration of a time, and conformity of the International Standard. Moreover, the three-dimensional CAD system for verifying to construct three-dimensional CAD data of civil infrastructure was developed. The experiments using three-dimensional CAD engine and system showed that they are adapted to generate three-dimensional CAD data in civil infrastructure construction projects.

Smart phone allows easy acquisition of pedestrian trip data. Consequently, it is expected that pedestrian trip data will be utilized in some fields such as disaster response and transportation. Depending on the uses such as disaster situations, accurate pedestrian trip data on the real-time basis is required. However, the location information acquired from GPS sensor of respective smart phone exhibit unevenness in the accuracy and contain plenty of noises since they differ from each other depending on the surrounding environments or models. There is a possibility that analysis of enormous amounts of pedestrian trip data can handle the problem mentioned above. However, this is not satisfactory for the uses in emergency as it lacks real-time performance. In this research, we devised a method of noise reduction by using PDOP, circular error probability, and pedestrian trip data in order to acquire three-dimensional location information with high certainty in real time from pedestrian trip data acquired by smart phone. Then this method was applied to the probe-person research data to verify its usefulness.

Ministry of Land, Infrastructure, Transport and Tourism (MLIT) in Japan is promoting the intelligent construction for productivity improvement, quality assurance, and cost reduction. In the intelligent construction, as-built management using Total Station (TS) is conducted. In this situation, a three-dimensional design data is manually created based on a two-dimensional drawing. And this puts a burden to contractors. Therefore, it is necessary to create a three-dimensional design data automatically. In order to solve this problem, there is a three-dimensional polyline utilized in Machine Control and Machine Guidance (MC/MG). This polyline data has the information required to create a three-dimensional design data. In addition, there are sites where MC/MG is combined with as-built management using TS. Therefore, if a three-dimensional design data is automatically created using a three-dimensional polyline, it could reduce the time and cost to create it. In this research, a system of generating three-dimensional design data based on three-dimensional polyline was developed. And we verified feasibility in the actual construction site.

High-strength bolts of steel bridges gradually loosen in service. In construction and maintenance of steel bridges, it is necessary to develop the method that can infer axial force of high-strength bolts in joints by nondestructive inspection. The loosening of high-strength bolts has to be inspected by experts with hammers in the past. The axial forces of bolts have to be reasoned quantitative for the accurate inspection. A system for inferring axial force of highstrength in steel bridges using waveform data provided by a hitting of automatic looseness detector. The system has been based on a neural network with faculty of pattern recognition. However, that system requires not only such reactionary waveform data but also the grip length of bolts. In the present paper, the system was constructed for inferring axial force and grip length of high-strength bolts without being given such grip length data. Firstly, reactionary waveform data was pretreated through fast Fouriertransform(FFT)for extracting grip length information. The method to construct a system was examined using amplitude spectra and phase-angle spectra after FFT. As a result, the system was obtaind the best reasoning accuracy of the axial force by using both amplitude spectra and phase-angle spectra. This system was demonstrated its usability of reasoning the axial force of high-strength bolts in all existing steel bridges. This system can utilize not only looseness inspection in service but also inadequate tightening torque in construction. By using the system, everybody can infer the axial force in sequence if they hit high-strength bolts without mastery of skills. This study can adjust the lack of expert engineer, and improve an inspection method of structure relied on hunch.

In construction and maintenance of steel bridges, it is necessary to develop the method that can infer axial force of high-strength bolts in joints by nondestructive inspection. The loosening of high-strength bolts has to be inspected by experts with hammers in the past. The axial forces of bolts have to be reasoned quantitative for the accurate inspection. We have develolped a system for inferring axial force of high-strength in mediuam and small-sized steel bridges using waveform data provided by a hitting of automatic looseness detector. The system has been based on a neural network with faculty of pattern recognition. However, the system was not able to be applied long high-strength bolts on the joints of great length bridges. In the present paper, the system was constructed for inferring axial force of high-strength bolts jointed in not only medium and small-sized bridges but also great length bridges and jointed in secondary members. The system can infer axial force simply and accurately in the building site. Firstly, the new method for adjusting the automatic hammer was decided and the usefulness was verified. Secondly, the relation between grip length of high-strength bolts and the inferred axial force was cleared in details, because the grip length is the most concerned bridge scale. The practical system was constructed in consideration of grip length. Axial force of various high-strength bolts on the joints was inferred using experimental model. The experimental model was made after I-girders of a steel bridge, given the same structure and almost same dimensions. The system was verified for practical use in the case of various bolts on the secondary members. The system can infer both the installed axial force in construction and the residual axial force in service. Using this system, axial force of bolts can infer easily without extracting high-strength bolts. Therefore, improvement of productivity is anticipated in construction and maintenance of steel bridges.

The loosening of high-strength bolts in spliced joints of steel bridges has been founded during their inspection and maintenance. High-strength bolts can become loose if inadequate tightening torque was applied to them during the construction of bridges. or bridges in service may present some high-strength bolts loosened naturally with the passage of time. However, the method that can satisfy both work efficiency and inferring accuracy was not developed. In the present paper, the new method for inferring axial force of high-strength bolts was developed using neural network. The system to infer axial forces from the reaction and acceleration waveforms collected by the automatic looseness detector was built based on a neural network with the faculty of pattern recognition. First, the number of waveform data to be given to the neural network, the normalization and smoothing methods of waveform data were tested. Second, for practical use of the system, the relations between the arrangement and length of bolts, the thickness of web plates and spliced plates, and so on. As a result, the system that infer both the installed axial force in construction and the residual axial force in service of medium and small sized steel bridges was established.

近年,建築物や交通機関のユニバーサルデザイン(UD)化が進められているが,すべてをUD化することは困難である.そこで,地図と関連した情報を表示するUDマップがWeb上で増えてきているが,情報の固定化と氾濫が問題となっている.さらに,現在のUDマップの多くは2次元であり,高さに関するバリア情報の表現が不十分である.本研究では,3次元空間データを利用した住民参加型でUD情報を集めるUDマップにおいて,バリア・バリアフリー情報を示すUD情報を分類し,ユーザ特性ごとにUD情報をフィルタリングして提示する機能,そして運用を視野に入れ,UD情報を管理する機能を開発した.

筆者が所属する研究グループでは,携帯電話を用いた観光情報システムの開発を行なってきた.音声での自動配信が有用であることがわかっているが,観光情報に分類される全ての情報を音声で提供するのは音声ファイル作成コスト(時間・価格)の観点から見て困難である.また音声での情報提供に関して,観光客からは音声の速度や話者変更が行える機能の要望がある.これらを踏まえると観光情報システムにおける音声提供に関して,音声合成の導入を行うことが現実的であると言える. 本研究では,音声合成技術を用いて音声も含めた情報提供を行うシステムの開発・運用を行い,観光情報システムにおける音声合成の導入について考察する.
