Abstract(J)	高速道路の交通流改善によるCO₂削減効果を推計するため，個車挙動を再現する交通流シミュレーションを設計・検証し，乗用車・大型車の燃費シミュレーションと連成した．複数車線区間において，車線内の速度分布幅の縮小により，個車の車線変更や加減速頻度が低下しCO₂の総排出量が削減されることを定量的に示した． Translation
Abstract(E)	To estimate the CO₂ reduction effect of improving traffic flow on expressways, a traffic flow simulation was designed and validated to reproduce individual vehicle behaviors, and was coupled with fuel consumption simulations for passenger cars and heavy-duty vehicles. On multi-lane sections, narrowing the speed range within lanes reduced the frequency of lane changes and acceleration/deceleration, quantitatively demonstrating a decrease in total CO₂ emissions.

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
