Beijing transport authorities has found the number of trips in the city by cars as a proportion of trips by all mainstream modes of transport has fallen for the first time since the commission began conducting the research in 1986, the survey findings said.
The city has over 5.5 million vehicles and more than 3.6 million privately owned cars.
The commission also considered subway, bus, bicycle and walking in the calculation.
It put the drop largely down to bus lanes, parking price hikes, Beijing's car plate lottery system and alternate traffic restrictions by car plate numbers on weekdays, state- run Xinhua news agency reported.
The survey found the average distance covered by each car in 2014 was 15,000 km, 1.5 times the number in London and twice the number in Tokyo.
The traffic problem is such that Beijing is still considering congestion tax to further ease the pressure during peak times.
