(Bloomberg) — Abu Dhabi commuters have to add one more item to their expense list, as the oil-rich emirate follows its neighbor Dubai by introducing an electronic road toll collection system from Oct. 15.

Authorities will set up four toll gates on major bridges leading to the United Arab Emirates’ capital, the Department of Transport said in a statement. The move would “reduce traffic congestion and raise the efficiency of the transport sector without having to stop for paying toll fees,” it said.

Abu Dhabi is expecting an annual revenue of 400 million dirhams ($109 million) from the toll gates, Ibrahim Al Hamoudi, acting executive director of the surface transport sector at the department, told reporters.

The change is the latest in a series of measures designed to bolster non-oil revenue in the Gulf in the wake of the 2014 oil-price crash. The U.A.E., a federation of seven emirates, led the way in reducing fuel subsidies and was the first with Saudi Arabia to introduce the value-added tax.

The Abu Dhabi government also increased its municipality fees for all rented premises in June last year to as much as 7.5% from 3%.

Dubai introduced toll systems almost 12 years ago. It later used financing backed by road-toll receipts to help fund transport projects in the emirate.
