The document discusses the future of transportation. It notes that transportation currently poses environmental concerns such as pollution, climate change, and health hazards. It then outlines options for improving transportation such as intelligent transportation systems, alternative fuels like biodiesel and electricity, and alternative modes of transportation including high-speed rail, electric vehicles, and telecommuting. Finally, it discusses current developments in electric vehicles and hybrid vehicles and their advantages like lower costs and emissions but also limitations like battery life and lack of infrastructure.
