  2. Sustainable transport - Wikipedia

    en.wikipedia.org/wiki/Sustainable_transport

    Sustainable transport policies have their greatest impact at the city level. Some of the biggest cities in Western Europe have a relatively sustainable transport. In Paris 53% of trips are made by walking, 3% by bicycle, 34% by public transport, and only 10% by car. In the entire Ile-de-France region, walking is the most popular way of ...

  3. Transportation theory (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Transportation_theory...

    In mathematics and economics, transportation theory or transport theory is a name given to the study of optimal transportation and allocation of resources. The problem was formalized by the French mathematician Gaspard Monge in 1781. [1] In the 1920s A.N. Tolstoi was one of the first to study the transportation problem mathematically.

  4. Green transport hierarchy - Wikipedia

    The green transport hierarchy (Canada), street user hierarchy (US), sustainable transport hierarchy (Wales), [1] urban transport hierarchy or road user hierarchy (Australia, UK) [2] is a hierarchy of modes of passenger transport prioritising green transport. [3] It is a concept used in transport reform groups worldwide [4][5] and in policy ...

  6. Transport network analysis - Wikipedia

    en.wikipedia.org/wiki/Transport_network_analysis

    t. e. A transport network, or transportation network, is a network or graph in geographic space, describing an infrastructure that permits and constrains movement or flow. [1] Examples include but are not limited to road networks, railways, air routes, pipelines, aqueducts, and power lines. The digital representation of these networks, and the ...

  7. Environmental impact of transport - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    The environmental impact of transport are significant because transport is a major user of energy, and burns most of the world's petroleum. This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide. [2][3] and also plant pollution, by heavy metals ...

  8. Green vehicle - Wikipedia

    en.wikipedia.org/wiki/Green_vehicle

    The Fiat Siena Tetrafuel 1.4 is a multifuel car designed to run as a flex-fuel on gasoline, or E20–E25 blend, or neat ethanol (E100); or to run as a bi-fuel with natural gas (CNG). A conventional vehicle can become a greener vehicle by mixing in renewable fuels or using less carbon intensive fossil fuel. Typical gasoline -powered cars can ...

  9. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less energy for continuous service) or changing one's behavior to use less service (for example, by driving less). Energy conservation can be achieved through efficient energy use ...
