London

The city of London is on a mission to make walking as convenient as possible, using smarter traffic signals that reduce wait times for pedestrians.

Leave it to a Brit to deliver a mathematical smackdown this courteously.

Sometimes it's astounding how rider-friendly transit service has become in other countries compared to America.

Heavy trucks with big blind spots are a deadly menace to cyclists and pedestrians.

In case you're looking for a good visual to show how bike lanes can be extremely efficient transportation infrastructure, check out this short video from the UK-based advocacy group Sustrans. It shows rush hour on the Blackfriars Bridge "cycle superhighway" in London on a Tuesday morning.

Following the death of 26-year-old cyclist Ying Tao, British Prime Minister David Cameron said he would look into a truck ban for city centers throughout the UK.

Five years ago, David Love experienced Summer Streets in NYC and was so captured by the warmth and excitement he decided to bring open streets to London.

Transport for London, that city's regional transit operator and planning agency, has had a "daily cap" on bus, tram, and train fares since 2005. The fare system stops charging pay-as-you-go riders for trips once they spend a certain amount, which depends on which services you use and zones you visit. This means that you'll never spend more on transit in one day than a daily pass would have cost (sometimes even less), which gives everyone the value of a day pass without making people buy those passes in advance.

Organizers of major sporting events, from this weekend's "Mass Transit Super Bowl" to the Sochi Olympics a week from now, may benefit from a lesson learned during the 2012 London Olympics: a tactic transportation planners secretly call “the Big Scare.”
