English, Scientific journal, Abstract
The “Prevention through Design” (PtD) concept considers construction safety during the design process. Several countries are currently practising PtD, including the UK, Singapore, Malaysia, Australia, and the USA, which is still not the case in the Philippines. The study presented in this paper aimed to indicate the current level of awareness of the PtD concept among the structural engineers and purposed to generate a basis of initiatives to introduce or improve the understanding and adoption of PtD in the Philippines. A knowledge, attitude, and practice (KAP) questionnaire was distributed to survey respondents selected through a snowball sampling method, consisting of structural engineers currently working in the Philippines. Sixty-one (61) structural engineers responded and were analysed in this study. Results indicated that PtD was relatively a new concept for most structural engineers in the Philippines. Similarly, the designers’ knowledge of the concept was still low. However, structural engineers viewed PtD as necessary and its implementation as essential in the construction industry. Despite the known concerns in the PtD implementation, structural engineers favoured the adoption of the concept. The paper also discussed challenges and key drivers for implementing PtD in the Philippines based on the questionnaire results and supporting literature reviews. The findings and methodology presented in this paper could serve as a baseline for a larger sample size covering other design trades, such as architectural, electrical, and mechanical design services leading to the broader adoption of PtD in the Philippines. Furthermore, the framework of this study could also apply to other countries with similar contexts. - Development of Speed Adjustment Delineator to Assist Smooth Merging on the Expressway

Japanese,In the present study, objective is to reveal the driver's subjective risk perception when closing to a preceding vehicle in car-following situation under snowy or dry/wet road conditions. It was assumed that the driver uses the ACC to follow a preceding vehicle, and the preceding vehicle decelerated and approached. The results of the field experiment shown that the driver's subjective risk perception to the preceding vehicle was increased by ACC use. The models for estimating the driver's subjective risk perception to the preceding vehicle based on values of the 1/TTC and the 1/THW in the situation of preceding vehicle deceleration were delivered in each type of road conditions (Risk Feeling equation). From the Risk Feeling equation, the THW of the ACC, which corresponds to the conventional driving of the driver's subjective risk perception to the preceding vehicle, is shown in each road conditions. It was suggested that longer value of the THW is required to reduce driver's risk feeling when driving with ACC on snowy roads.

Japanese, Scientific journal,This study proposed speed adjustment delineators embedded in the center of the travel lane as a preliminary speed adjustment device for drivers who is operating a semi-automated vehicle to reduce conflicts with the merging vehicles on the expressway. We conducted experiments using a driving simulator with 46 participants, and the results of driving records and subjective evaluations showed that the information provided about speed adjustment delineators affected the driver's avoidance behavior. The participants who were explained the intention of the speed adjustment delineators selected the appropriate speed adjustment to follow the instructions of the speed guide light at the upstream of the nose end in the merging section. This result led to merging behavior smoothly and reduced the subjective risk perceived by the drivers due to the merging vehicles. In addition, based on the acceleration and deceleration behavior of drivers when the speed guide lights were not turned on, the proper location of the speed adjustment delineators were revealed.

Japanese, Scientific journal, This study tries to support merging behavior by providing information about the behavior of the mainline vehicle as a next-generation Human-Machine Interface (HMI) based on Augmented Reality (AR). Also, in this paper, we verify the effectiveness of visual information on the driver using AR by analyzing the gaze. Specifically, this paper provides information on the timing in which the merging vehicle cannot merge by using AR to the driver. This information is generated based on the position and speed of the mainline vehicle. In this study, a Virtual Reality (VR) driving simulator that can measure the gaze was developed for experiments. By utilizing the VR driving simulator, driving experiments that provide various kinds of information including AR to the merging vehicle was performed. Also, by using the obtained data at the driving experiments, the driver's gazes are analyzed. In this gaze analysis, we verify the burden on the driver of checking the mainline is reduced by the information provision. Furthermore, the timing of the merging is measured to evaluate the safety and smoothness of the merging. The experimental results suggested that providing the unsuitable timing of merging by AR enables the driver to understand easily the condition of the mainline. - EFFECTS OF WINTER ROAD SURFACE ON DRIVER’S RISK AVOIDANCE BEHAVIOR WHEN THE VEHICLE ARE ENTERING A CURVE WITH ADAPTIVE CRUISE CONTROL

Japanese,In winter, to drive a vehicle has a lot of difficulties due to road slipperiness, low visibility and narrowed road by lying snow. Understanding the driving environment where the driver feels danger is necessary to introduce SAE Level 2 or 3 in winter, so the present study aims to clarify driver's risk avoidance behavior when the drivers are using adaptive cruise control (ACC) under the winter road conditions. In an experiment on public road, a total 6 participants drove the test vehicle with ACC-ON conditions on the expressway and several local highways. We measured driver's risk avoidance behavior, and simultaneously measured road slipperiness, road geometry and weather condition. Results indicated that road slipperiness, road geometry and the vehicle speed have an effect on the occurring driver's risk avoidance behavior. Slippery road, hard geometry and high speed driving often lead the driver's risk avoidance behavior. According to this result, it is clarified that driver's risk avoidance behavior was reduced under low regulatory speed conditions on the expressway which the road geometry design was high level whereas the road surface conditions were slippery. It suggests that driver's risk avoidance behavior can reduce if the driving support system slows down before the vehicle approach such a slippery or hard geometry condition road.

Japanese,Many road videos obtained by CCTV and dashcams are accumulated in organization of road administrators. However, since these data are simply accumulated as original video files, the data transmission via networks is very high cost and huge sized storage is required. Also, in the road situations where some obstacles such as damaged parts of roads and any unexpected objects exist, bicycles cannot travel normally and are forced to avoid them. Therefore, by realizing detection of the avoidance behavior on bicycle trips, more effective road management by road administrators can be expected. In this paper, we propose an edge computing system for accumulating the data of the avoidance behavior on bicycle trips while reducing the data size. This edge computing system contributes to realizing more effective and efficient road management.

Japanese, Scientific journal, 本論文では,チームスポーツ映像からアクティブネットを用いてパス可能領域を推定する手法を提案する.チームスポーツ映像の一つであるサッカー映像の意味内容解析を行うために重要なサッカーの戦術は,選手の移動とボール運びによって表現されるため,ボール運びを実現するパスを分析することは重要である.一般にパスコースはボール保持者と味方チームの選手へとつながる緩やかな曲線で表される.提案手法では,新たなエネルギーの定義とパス可能領域を推定するための画像生成により,アクティブネットを用いて前述の曲線が存在する領域を抽出する.また,パス可能領域は守備の選手から離れるほど,パスが成功する可能性が高いという特徴をもつ.提案手法では,格子点の密度に着眼することで,パスが成功する可能性をパス可能領域の推定と同時に得る.更に,アクティブネットの収束結果は多少の選手位置の誤差を許容するため,選手の動きを用いた従来手法における,選手位置の誤差の影響を受けやすいという問題点を解決することが可能である.したがって,提案手法はカメラワークが存在し,高精度な選手位置の推定が困難であるテレビ映像に対しても,高精度にパス可能領域の推定が可能である.

映像情報メディア学会, Japanese - [Paper] A Method of Important Player Extraction Based on Link Analysis in Soccer Videos
Takahashi Sho, Haseyama Miki, ITE Transactions on Media Technology and Applications, 5, 2, 42, 48, 2017
In this paper, a method for extraction of important players in soccer videos based on link analysis is proposed. In a soccer match, players perform shoot tackles, assistance, and covering. Furthermore, the soccer tactics are defined the formation of players based on various relationships between players. The proposed method extracts the important players, in order to obtain information for understanding the soccer matches for various audiences. Specifically, our method notes that relationship between players, who cooperate with each other by the pass and the covering, is similar to relationship between web pages which are connected by links. First, the proposed method obtains player networks based on relationship between players in each team. The relationships are defined based on player positions and the possibility of the pass or the covering between players. Finally, in the proposed method, by applying the link analysis to the obtained player networks, important players are extracted. By realizing this approach, important players are extracted from the player networks based on the possibility of the pass or the covering between players. In the last of this paper, the above link analysis-based method was applied to actual soccer matches to show the reasonability of our method., The Institute of Image Information and Television Engineers, English - 深層学習によって得られる画像特徴量を用いた道路構造物の点検データ検索の高精度化に関する検討

The Institute of Image Information and Television Engineers, English - A Study on Detection of Similar Scenes based on Pass Regions in Soccer Videos
TAKAHASHI Sho, HASEYAMA Miki, ITE Technical Report, 40, 0, 9, 12, 2016
This paper proposes a pass region-based method for detecting similar scenes in soccer videos. In the soccer games, since the pass is very useful for analyses of various soccer tactics, the visualization of the pass regions is a very important task. Generally, since the tactics are defined by the formation of players, in the case of same tactic in two soccer scenes, the pass course is considered to be similar. Therefore, in this paper, we propose a detection method of similar scenes by utilizing the pass regions in soccer videos., The Institute of Image Information and Television Engineers, Japanese - サッカー映像における試合内容の理解を促すデータの提示に関する検討

映像情報メディア学会, Japanese - A Study on High Performance Parallel Computing for Active Net-based Pass Region Estimation in Soccer Videos
TAKAHASHI Sho, HASEYAMA Miki, ITE Technical Report, 39, 0, 1, 6, 2015
This paper proposes a high performance parallel computing for Active net-based pass region estimation in soccer videos. In the soccer games, since the pass is very useful for analyses of various soccer tactics, the visualization of the pass regions is a very important task. Therefore, the pass region estimation method based on Active net is proposed. However, computation time of the pass region estimation must be reduced. Thus, in this paper, we propose a high performance parallel computing for Active net-based pass region estimation. By utilizing CUDA^as the computation environment, the high performance parallel computing is realized., The Institute of Image Information and Television Engineers, Japanese - A Note on Estimation of Group Advantage for Group Tactics Analysis in Soccer Videos
TAKAHASHI Sho, HASEYAMA Miki, ITE Technical Report, 39, 0, 7, 12, 2015
This paper reports a effectiveness of the estimation method of group advantage in soccer videos. The group advantage represents the degree of team's superiority or inferiority in each group. For this analysis, the proposed method classifies players into some groups. As a result of this classification, the players in one group are closely related in terms of soccer tactics. In this method, the relationship between the players in the groups are analyzed by using player positions. Then, this method estimates group advantages by utilizing the relationship of the players. In the last of this paper, by utilizing the actual soccer videos, we evaluate the estimation method of the group advantage., The Institute of Image Information and Television Engineers, Japanese - 複数の画像特徴を用いたベイジアンネットワークに基づく構造物の変状の推定の高精度化に関する検討

TAKAHASHI Sho, HASEYAMA Miki, ITE Technical Report, 38, 0, 1, 4, 2014
This paper proposes a link analysis-based method for detecting important players and similar scenes in soccer videos. We define important players as follows: 1) the attacking player who have great relevancy to a score, 2) the defending player on the opposing team, and 3) players who assist the above players. Since soccer tactic analysis focuses not only on player skill but also relationships between players, this paper expresses the relationships between players as a network, which is constructed from player positions in the soccer video. The proposed method analyses the constructed network to detect important players and similar scenes., The Institute of Image Information and Television Engineers, Japanese - ベイジアンネットワークを用いた構造物の点検データからの変状の推定

本論文では，サッカー映像からレベルセット法を用いて選手を追跡する手法を提案する．提案手法では，サッカー映像を各フレームが時間軸方向に重なるように連結した三次元データとして扱う．このデータに対して，レベルセット法を適用することで抽出される三次元の領域は，複数フレームに渡って存在する同一選手を包含する．提案手法では，この三次元の領域をサッカー映像から抽出することで，選手の追跡を実現する．したがって，提案手法では，フレームごとに選手を検出する必要がないため，フレームを個別に処理する従来手法における選手の検出と追跡それぞれの誤差によって精度が低下する問題を解決可能である．また，我々は，ユニフォームの色成分をサッカー映像から色コリログラムを用いて推定し，これをレベルセット法を用いて追跡する選手の特徴として導入する．これにより，提案手法では，追跡対象の特徴を事前に与えることなく，選手の頑健な追跡が可能となる．本文の最後では，実際にテレビで放送されたサッカー映像に対する実験により，提案手法の有効性を確認する．, The Institute of Electronics, Information and Communication Engineers, Japanese - A Note on Soccer Player Tracking Using Elastic Model : Performance Improvement Based on New Potential Energy

TAKAHASHI Sho, HASEYAMA Miki, IEICE technical report, 109, 414, 185, 190, 08 Feb. 2010
This paper proposes an estimation method of 3D pass regions from the actual broadcasted soccer videos, where the 3D pass region has a high probability in which the pass succeeds. We have proposed an estimation method of 2D pass regions by using player positions and a ball position, where the player positions and the ball position are obtained as 2D coordinate from the actual broadcasted soccer video. However, the pass regions exist on a 3D space as a region of a 3D shape. Therefore, the proposed method realizes the estimation of the 3D pass region from the 3D space by using the 3D Active Grid. In order to use the 3D Active Grid, new volume data are generated by using player and ball positions, where the volume data indicate a possibility in which players can reach positions in the 3D space. Consequently, this paper realizes the estimation of the pass regions by using the 3D Active Grid., The Institute of Electronics, Information and Communication Engineers, Japanese - A Note on 3D Active Grid Based Estimation of 3D Pass Region from Broadcasted Soccer Videos

International Conference on Digital Signal Processing, DSP, 01 Mar. 2017
© 2016 IEEE.A distress classification method of road structures via decision level fusion is presented in this paper. In order to classify various kinds of distresses accurately, the proposed method integrates multiple classification results with considering their performance, and this is the biggest contribution of this paper. By introducing this approach, it becomes feasible to adaptively integrate the multiple classification results based on the accuracy of each classifier for a target sample. Consequently, realization of the accurate distress classification can be expected. Experimental results show that our method outperforms existing methods. - A Study on Object Extraction in Steel Tower Videos Shot by Inspection of Transmission Line Tower

2016 IEEE 5th Global Conference on Consumer Electronics, GCCE 2016, 27 Dec. 2016, English
© 2016 IEEE.A decision-level fusion (DLF)-based team tactics estimation method in soccer videos is newly presented. In our method, tactics estimation based on audio-visual and formation features is newly adopted since the tactics of the soccer game are closely related to the audio-visual sequences and player positions. Therefore, by using these features, we classify the tactics via Support Vector Machine (SVM). Furthermore, by applying DLF to the SVM-based classification results, the two modalities are integrated to obtain more accurate tactics estimation results. Some results of experiments verify the superiority of our method. - Retrieval of similar inspection records based on metric learning using experienced inspectors' evaluation

2016 IEEE 5th Global Conference on Consumer Electronics, GCCE 2016, 27 Dec. 2016
© 2016 IEEE.This paper presents a retrieval method of similar inspection records in road structures based on metric learning using experienced inspectors' evaluation. Inspection records of road structures include images and text-based information such as category of distress, damaged parts and degree of damage. The proposed method calculates distances from query inspection records, and rank lists of retrieval results are obtained for each feature. In this approach, the distance quantification are updated on the basis of experienced inspectors' evaluation. Finally, the proposed method obtains retrieval results by integrating the multiple rank lists. The experimental results show the effectiveness of the proposed method. - A Study on Detection of Similar Scenes based on Pass Regions in Soccer Videos

TAKAHASHI Sho, HASEYAMA Miki
ITE Technical Report, 03 Dec. 2015, Japanese
This paper proposes a high performance parallel computing for Active net-based pass region estimation in soccer videos. In the soccer games, since the pass is very useful for analyses of various soccer tactics, the visualization of the pass regions is a very important task. Therefore, the pass region estimation method based on Active net is proposed. However, computation time of the pass region estimation must be reduced. Thus, in this paper, we propose a high performance parallel computing for Active net-based pass region estimation. By utilizing CUDA^as the computation environment, the high performance parallel computing is realized. - A Note on Estimation of Group Advantage for Group Tactics Analysis in Soccer Videos
TAKAHASHI Sho, HASEYAMA Miki
ITE Technical Report, 03 Dec. 2015, Japanese
This paper reports a effectiveness of the estimation method of group advantage in soccer videos. The group advantage represents the degree of team's superiority or inferiority in each group. For this analysis, the proposed method classifies players into some groups. As a result of this classification, the players in one group are closely related in terms of soccer tactics. In this method, the relationship between the players in the groups are analyzed by using player positions. Then, this method estimates group advantages by utilizing the relationship of the players. In the last of this paper, by utilizing the actual soccer videos, we evaluate the estimation method of the group advantage. - 道路構造物の変状画像に対する類似検索の高精度化に関する検討

TAKAHASHI Sho, HASEYAMA Miki
ITE Technical Report, 05 Dec. 2014, Japanese
This paper proposes a link analysis-based method for detecting important players and similar scenes in soccer videos. We define important players as follows: 1) the attacking player who have great relevancy to a score, 2) the defending player on the opposing team, and 3) players who assist the above players. Since soccer tactic analysis focuses not only on player skill but also relationships between players, this paper expresses the relationships between players as a network, which is constructed from player positions in the soccer video. The proposed method analyses the constructed network to detect important players and similar scenes. - 複数の画像特徴を用いたベイジアンネットワークに基づく構造物の変状の推定の高精度化に関する検討

2014 IEEE 3rd Global Conference on Consumer Electronics, GCCE 2014, 03 Feb. 2014
© 2014 IEEE.This paper presents a Bayesian network-based method for estimating a distress of road structures from inspection data. The distress is represented by a damage of road structures and its degree. In the previous work, the distress was estimated by utilizing Bayesian network based on categories of road structures, details of road structures and damaged parts. However, inspection data include not only the above items but also images of the distress. Therefore, by introducing the use of the images to the previous work, improvement of the distress estimation accuracy can be expected. The proposed method calculates Bayesian network from inspection items and their corresponding images to perform the distress estimation. Experimental results show the effectiveness of the proposed method. - Adaptive parameter setting for pass region estimation in soccer videos and its performance verification
Sho Takahashi, Miki Haseyama
2013 IEEE 2nd Global Conference on Consumer Electronics, GCCE 2013, 01 Dec. 2013
This paper proposes an accurate pass region estimation method by introducing adaptive parameter settings. Our previous paper proposed a pass region estimation method by utilizing average values of ball and player velocities. However, such velocities vary according to player density and skill. Therefore, in order to realize a more accurate pass region estimation, the proposed method obtains parameters, which are ball and player velocities, from player positions in a target soccer video. By introducing the above parameter settings to pass region estimation, more realistic pass region can be obtained. Consequently, the accurate method of pass region estimation is realized. © 2013 IEEE. - ベイジアンネットワークを用いた構造物の点検データからの変状の推定

電子情報通信学会技術研究報告, 14 Feb. 2011, Japanese
In this paper, an accurate method of pass region estimation method is proposed by introduceing an adaptive parameter settings. We have proposed a pass region estimation method by utilizing average values of ball's velocity and player's velocity. However, velocities of a ball and players are different according to player's density and player's skill. Therefore, in the proposed method, parameters, which are a velocity of a ball and velocities of players, are set by using obtained player's positions from a target soccer video. Consicuently, the accurate method of pass region estimation is realized. - A Study on Accurate Pass Region Estimation in Soccer Videos : Introduction of Adaptive Parameter Settings

高橋翔, 長谷山美紀
映像情報メディア学会技術報告, 15 Feb. 2010, Japanese
This paper proposes an estimation method of 3D pass regions from the actual broadcasted soccer videos, where the 3D pass region has a high probability in which the pass succeeds. We have proposed an estimation method of 2D pass regions by using player positions and a ball position, where the player positions and the ball position are obtained as 2D coordinate from the actual broadcasted soccer video. However, the pass regions exist on a 3D space as a region of a 3D shape. Therefore, the proposed method realizes the estimation of the 3D pass region from the 3D space by using the 3D Active Grid. In order to use the 3D Active Grid, new volume data are generated by using player and ball positions, where the volume data indicate a possibiliy in which players can reach positions in the 3D space. Consequently, this paper realizes the estimation of the pass regions by using the 3D Active Grid. - A Note on 3D Active Grid Based Estimation of 3D Pass Region from Broadcasted Soccer Videos

本年度は以下のトピックについて研究に取り組み，成果を得た．
１．経路選択行動の仮定を必要としないOD推定手法の構築
道路ネットワークをグラフとして見立て，グラフカットにより定義される強連結成分をゾーンとして定義した条件において，任意のゾーン間（ODペア）の交通量を推定する基礎モデルを構築した．具体的にはゾーン間を通過するリンクがすべて交通量観測可能であり，車両位置情報からゾーン間推移の履歴のサンプリングデータが存在する前提において，リンク交通量の観測誤差がなく，車両位置情報がダイレクトスケーリングであるときには誤差なくゾーン間交通量が推定できるモデルを構築した．構築したモデルを仮想ネットワークで適用した結果，想定した通りの挙動を示すことを確認した．この内容は第６８回土木計画学研究発表会にて報告した．くわえて，次年度以降に取り組む予定としている内容ではあるが，より都心部のゾーンは内内交通量が混雑の原因となるため，より適切にゾーンを分割するために有用な手法を構築し，高水準学術誌へ投稿し，載録された．
２．面的被害の生じた道路網のMFDに基づく供給性能変化分析
2021年度冬に発生した札幌における大雪のリンク交通量観測機の情報を用いて札幌中心市街地のMFDの変化を分析した．加えて，XRAIN降水強度を用いることで，降雪状況を踏まえたMFDの推移を考察した．この分析により，降雪があった日にはそうでない日と比較すると車両存在台数が増加する一方でスループットが減少し，MFDにヒステリシスループが発生することを確認した．この内容は交通工学論文集Vol.10(1)に採択された．

本研究では交通シミュレーションソフトの VISSIMを用いて、冬期路面を想定したACC制御車の混在が低交通量の交通流に与える影響について明らかにする。最初に、ACC制御車の走行をVISSIMで再現する追従モデルを開発した。次に、フィールド実験におけるACC制御車（追従車）の追従挙動を用いてVISSIMで再現したACC制御車の追従モデルの妥当性を検証した。これらの結果をベースに、冬期路面を想定した長い設定車間時間の影響を検討した。交通流シミュレーションの結果から、ACC制御車の混在率が高く、設定車間時間が長いとき、平均速度・平均旅行時間・平均遅れ時間に大きな影響はない結果となった。ただし、ACC制御車の混在率が高く時間交通量が多い条件で、設定車間時間を長くすると平均遅れ時間が長くなるなど、交通流へ影響する結果となった。

The formation of players is a very important element in tactics of field sports such as soccer, rugby football, and baseball, etc. These tactics are expressed by communicating with multiple players on the field. Thus, the analysis methods for the formation of players are necessary for understanding tactics of sports contents. Therefore, in this project, we constructed some advanced analysis methods for understanding tactics of sports contents based on the players' formation, and some visualization techniques which realize dynamic data indication with user’s skill and interest. The indicated data are players’ position, information of each team, a situation of the game, and tactics.
