This document discusses challenges and shares best practices regarding efforts to prepare a community/region for plug-in electric vehicles and charging infrastructure deployment

The database for public bike systems in China.

This article presents six detailed case studies of cycling in the Netherlands (Amsterdam and Groningen), Denmark (Copenhagen and Odense), and Germany (Berlin and Muenster). Except for Berlin, they represent the very best in coordinated policies and programs to make cycling safe, convenient, and attractive. Not only are cycling levels extraordinarily high in these cities, but virtually everyone cycles: women as well as men, the old and the young, the rich and the poor.

This study is part of the Africa Infrastructure Country Diagnostic (AICD), a project designed to expand the world’s knowledge of physical infrastructure in Africa.

This report provides an assessment of performance of existing high occupancy vehicle (HOV) lane facilities in the United States and explores policy alternatives and effects related to conversion of existing HOV lanes to high occupancy toll lane operations.

While the biofuels wave seems to be gaining strength daily in the United States, there have also been many concerns about the implications of ramping up biofuels production. This report is intended to act as a tool to provide an overview of the current status of the major developments in the biofuels industry.

Nine major regions around the world have implemented or proposed various fuel economy and greenhouse gas emissions standards. Yet these standards are not easily comparable due to differences in policy approaches, test drive cycles, and units of measurement. This paper develops a methodology to compare these programs to better understand their relative stringency.

Noise pollution in large developing cities is an insidious issue. In such noisy cities, many people seem to have become accustomed to the higher noise levels that underpin their daily activities. Noise has not only been linked to many serious health risks, such as hypertension and heart disease, but also to a deteriorating quality of life, by interfering with speech, performance, and ultimately, productivity. This module discusses the aspects of noise, sources of road noise, the nature and scale of impacts, and remedial measures to mitigate noise pollution.

This module serves to assist policy-makers and their advisers in developing countries to determine the best measures to abate air pollution with limited information. The material presented draws upon knowledge gained from countries worldwide and provides practical advice to developing countries on how to develop legally enforceable air quality standards and simplified clean air implementation plans.
