Abstract(J)四輪車対自転車の出会い頭事故について,ドライブレコーダ,ドライビングシミュレータをもとにドライバ応答を検討した.自転車が現れた時のTTCが,ブレーキ反応時間と制動時間の和よりも小さければ衝突が発生した.事故再現によると,衝突被害軽減ブレーキは自転車の飛び出しによるものについては有効性が限定されていた.

Abstract(E)Car-to-cyclist intersection collisions were investigated using drive recorder data. It was confirmed that collisions occurred when the time-tocollision was smaller than the sum of the driver reaction time and the car deceleration at the time of the cyclist being visible to the driver. From driving simulator experiments, it was shown that the driver reaction time depends on the sight of the driver. Based on accident reconstruction simulations of cars with an ideal autonomous braking system, some collisions still occurred, which was related to cyclist’s rush out into the road.

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.
