Abstract(J)	薄暮から夜間の交通事故低減を目的に、照明を用い路面にシンボル等を投影することで、車両から周囲の歩行者等への注意喚起する路面描画ランプが検討されている。本稿では駐車場での車両後退時の歩行者事故防止を目的としたバックアップランプと連動して点灯する路面描画ランプについて着目した。歩行者が路面描画ランプの点灯に気づくため必要な明るさ、及び適した点灯方法を実験的に求めた結果について報告する。 Translation
Abstract(E)	The road projection lamp is currently being discussed internationally as a future automotive lighting technology. We report the required performance of road projection lamp for vehicle reversing. We conducted experiment at outside that simulated the ambient illuminance and the arrangement of lamps, and the ease of awareness and comprehension by the research subjects 24 people was evaluated. In particular both the required luminous intensity for recognizing of 3 light pattern projection and sensory evaluation of them were measured. As a result, the flash and sequential projection was superior in terms of visual perception. And sequential projection is best projection pattern by sensory evaluation.

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.
