Abstract(E)Predicting traffic accidents is an important issue for improving public safety. In this study, we developed an AI model which predicts the probability of traffic accidents in Fukuoka City with spatial and temporal resolutions of ~130m and 1 month, respectively. A multimodal machine-learning model was developed by combining various structured data (roads, demographics and economic statistics, weather, events, etc.) and satellite imagery, and was trained using personal injury accident data between 2016 and 2017 in Fukuoka City. As a result, the model succeeded in predicting the outcome for Fukuoka City in 2018 at an AUC of the ROC curve of 77%.

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.
