According to the U.S. Environmental Protection Agency, "in 2012, greenhouse gas emissions from transportation accounted for about 28% of total U.S. greenhouse gas emissions ... [increasing] by about 18% since 1990." Reducing those numbers is key in mitigating global climate change and now, innovative transit projects in London and Los Angeles aim to make an impact.

A group of architects, engineers, and artists proposed a novel way of creating protected bike lanes in traffic-clogged London: a floating bike highway along the Thames. The path, called the Thames Deckway, would run east-west along the river’s southern bank for about seven miles, from Battersea to Canary Wharf.

"London needs to think outside the box of conventional solutions to solve its deep-seated traffic and pollution problems, the River Cycleway Consortium said in a statement announcing the proposal. "The river Thames, London’s main transportation thoroughfare from Roman times up to the 19th century, is overlooked today as a major travel artery except for a handful of passenger boats."

... a new road design project dubbed the e-highway is aiming to reduce and maybe even eliminate the pollution problems caused by all this truck traffic [on highways out of the ports of Los Angeles and Long Beach]. The experimental system is being built along a mile of the corridor to test how highly polluting diesel truck traffic could instead run on emission-free electric power. If successful, this demonstration could offer a solution to pollution-related problems along ... other high-traffic roadways all over the world.

The e-highway consists of an overhead catenary system that will run along the outside lanes of both sides of the road, sort of like the overhead wires that provide power to electric buses, trolleys, and trains in cities.
