Abstract(E)The purpose of this study is to understand the actual situation of pedestrian crashes in Michigan (U.S.) and to create a scenario of fatal injury. Accident analysis was conducted based on the VIPA (Vulnerable Road Users Injury Prevention Alliance) datasets, and the accidents scenario were extracted from detailed field investigations and subsequent assessment of pedestrian kinematics. It was found that the fatal accidents of pedestrians while crossing the road were occurred with a passenger car at night. The detailed accident was analyzed in terms of AIS (Abbreviated Injury Scale) severity by body region and the frequency of AIS 3+ injured body regions were shown at head, thorax and lower extremity in a nighttime. The distribution of contacts were higher at head, thorax and lower extremity injuries from windshield, hood surface, and hood edge, respectively. In addition, injuries to the thorax and the lower extremity of AIS 3+ were observed only at night and the configuration of injuries were differed between day and night.

About search


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.
