TRB's Transportation Research Record: Journal of the Transportation Research Board, No. 2427 consists of 9 papers that examine ecospeed-controlled vehicles at signalized intersections; the attributes and value of ecologically friendly route choices; network-wide vehicle energy consumption and ecorouting; fuel economy of ecodriving programs in Manila, Philippines, and Tokyo, Japan; and preliminary testing and evaluation of ecolane applications.

This issue also explores a model for optimizing ecodriving at signalized intersections; input data for a motor vehicle emissions simulator; incorporation of carbon dioxide emissions and associated fuel consumption in the Texas A&M Transportation Institute Urban Mobility Report; and traffic emissions and air quality near roads in dense urban neighborhoods.
