This Record contains papers on environmental analysis, air quality, transportation-related noise, energy considerations, and alternative fuels. Achieving a comprehensive environmental review of proposed projects and obtaining the needed public involvement and agency approvals are major obstacles to all forms of transportation improvements. Three papers address various aspects of the environmental review process. The air quality papers papers in this Record examine issues of particulate matters and its dispersion near urban roadways, the comparative emissions of electric and gasoline vehicles, the regional emission impacts of eletric vehicles on electrified roadways, and remote sensing of carbon monoxide and hydrocarbons from passing motor vehicles. Three papers examine ways and costs of improving fuel economy, vehicle operating characteristics that affect fuel economy, and differences between Environmental Protection Agency-test fuel economy and actual on-the-road experience. One paper examines the cost-effectiveness of converting fleets to compressed natural gas.
