London taxis, with their friendly drivers who actually know where they are going, are ranked best in the world, according to an annual taxi poll.

一项有关出租车的年度调查显示，伦敦出租车因其态度友好、熟悉路线的出租车司机获评世界最佳出租车服务。

The survey by travel website hotels.com found London taxis, despite being the most expensive, beat rivals across the globe to head the list for the third consecutive¹（连贯的） years, scoring a total of 59 percent in votes on several categories by travelers.

London taxi drivers were voted both friendliest and most knowledgeable². Drivers in the English capital must pass a rigorous（严格的） examination called The Knowledge to earn their taxi license³.

New York's yellow taxis came second in the list, scoring 27 percent which was up 10 percentage points from last year even though Manhattan's cab drivers tied with Parisian taxi drivers as the rudest.

Travelers said New York had the most available taxis.

Cabbies in Rome were voted the worst drivers in the world with almost one in 10 travelers thinking the Italian capital had the world's worst taxi drivers when it came to the quality of driving.

"Traveling by taxi is one of the first experiences that many travellers have upon arrival in a new city. In fact, the research found that cabs are by far the most popular method of traveling from the airport to their hotel," a spokesman for hotels.com said in a statement.

The global poll scored city based taxis for their levels of cleanliness, value, quality of driving, knowledge of the area, friendliness⁴, safety and availability.

Rounding out the top five were Tokyo with a total score of 26 percent, Berlin with 17 percent, and Bangkok famed for its tuk-tuks scoring 14 percent.

The survey for hotels.com, part of the Expedia group, was conducted among over 1,900 travellers between May 11-28 this year.
