It is becoming harder to hail a cab during busy periods in the capital, as Hu Yongqi and Zhang Yuchen report from Beijing.

For many potential rush-hour passengers on Beijing's streets it has become an all-too-familiar sight.

And the jury is still out on how to resolve the problem, with experts calling for an end to heavy traffic congestion and a change in the way people travel, while taxi drivers bemoan "crippling" monthly franchise fees and rising fuel costs.

Foreigners frequently feel they are being singled out for such treatment.

Thomas Bork, country director of America's Development Foundation in China, has been traveling back and forth to the country since the early 1990s.

His memory of Beijing's taxis dates to 1996, the second time he arrived in the capital. Yellow vans operating as taxis were running throughout the city but taxi drivers, like many today, did not speak English. There was far less congestion and it was much easier to hail a cab than nowadays.

When Bork arrived in the capital for the fifth time, at the end of 2011, he found taking a taxi required luck and that this - just like the cab - rarely arrived.

"During the past three weeks in the area I live - Weigongcun in Haidian district - the number of taxis passing by has been zero," said Bork. "Even if I do manage to stop one, I have usually been rejected for various reasons: A couple of miles is not far enough, or the driver is going for a break."

Once Bork argued with a cabbie after the driver told him to get out. Unable to reach an agreement, he recorded the number of the car and called the taxi company, with the driver liable to a three-day suspension for breaching regulations.

"But I don't complain about the drivers when it comes to severely congested roads in bad weather or in rush hours," he said. "A few times, the driver has even suggested I take the subway even though I was in his car."

Bork said one last resort was to take an illegal taxi charging fares that were twice the going rate.

A PE teacher at an international school in Beijing, who gave his name only as David, said arguing with a taxi driver only made him angrier. The US citizen, who has been in the city for two years, said he had been rejected by a cabbie nearly every day, sometimes merely for standing on the wrong side of the road.

From Dec 28, taxi drivers who fail to pick up passengers face suspension from work for one to three years, being blacklisted and never working in the industry again, according to the Beijing Municipal Transportation Administration Bureau.

Although 66,000 taxis ply the capital's roads, many people like Bork still find they are unable to hire a cab during rush hours or in extreme weather conditions such as torrential rain or on snowy days. The number of cabs in Beijing has not changed for more than a decade and the current fleet is unable to meet the demands of an increasing population.

It is estimated that about 10,000 taxis suspend their service during rush hours, making it more difficult to find a cab, according to a report by People's Daily. Experts suggest that competition should be introduced to the industry to provide better service.
