Abstract(J)本研究では,交差点におけるリアルタイムリスク予測手法を提案する.現場で観測した交通データを活用し,車両や歩行者ごとに信号状態や速度を考慮して,過去の類似状況から将来のニアミスリスクとその危険候補を効率的に抽出した.本手法により,複数主体が交錯する可能性を同時かつ俯瞰的に予測可能とした.

Translation

Abstract(E)This study proposes a real-time risk prediction method for intersections. Using traffic data observed on-site, the proposed method considers signal states and speeds separately for vehicles and pedestrians and efficiently extracts future near-miss risks and their potential hazards based on past similar situations. Such a framework enables us to holistically and simultaneously predict potential conflicts among multiple traffic participants.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
