Cab-hailing service Uber has hiked its ride-time charges in the Delhi-National Capital Region, PTI reported on Friday. The firm charges Rs 6 per kilometer up to 20 kilometers and Rs 12 per km after that. Pricing has been one of the major factors in the fierce competition between taxi aggregators Ola and Uber in the Delhi-NCR zone.

The ride time charge is calculated by the company on the basis of the total time of the ride. “Starting January 5, 2017, we have made some changes to our pricing structure in Delhi, NCR in order to serve the city better,” a company spokesperson told the news agency.

In 2016, Uber launched an “upfront fare” which is based on the estimated time taken, distance and traffic patterns. Demand influences the final rates. India is the company’s second largest market, with the United States-based company running operations in 29 Indian cities.

Correction: An earlier version of the story quoted PTI reporting that Uber was hiking fares by up to 50% in the National Capital Region, which the company claimed was an error.
