Dubai: Can traffic be eased by imposing congestion charge?

London, San Diego, Stockholm, Singapore and Milan are some of the busiest cities in the world that impose congestion charge — a tariff on motorists to enter and drive around busy areas at certain times of the day. It is used not only to ease traffic but also to improve air quality and generate income to improve public transport.

In London, for example, a £15 congestion fee is charged on most cars and motor vehicles being driven in Central London between 7am and 6pm from Monday to Friday, and between 12pm and 6pm on weekends and bank holidays (except between Christmas Day and New Year's Day).

Can congestion charge be rolled out in Dubai to reduce traffic, cut pollution, and raise money for mass transit? Khaleej Times asked transportation experts and urban planners to share their views.

Dr Monica Menendez, associate dean of Engineering for Graduate Affairs at New York University Abu Dhabi (NYUAD), explained: “Congestion charge is an economic tool to reduce traffic congestion. If the price of something goes up – be it a piece of clothing or the use of a road – typically, the demand for it goes down. As such, congestion charge is used to deter people from using certain roads at certain times of the day, potentially alleviating congestion and all the negative externalities associated with it, including air pollution.”

“The revenue from congestion charges can definitely be used to improve other more sustainable modes of transportation (e.g., public transportation), which, in the long term, could also contribute to the mitigation of traffic congestion,” she added.

For this to happen, drivers must have either the flexibility to change the travel times, change routes, or take other modes of transportation such as bus or metro.

“In the absence of such flexibility, the demand will not change, and congestion levels might not go down,” underscored the NYUAD professor of civil and urban engineering.

Added expense to motorists

The main contention, however, is that if ever congestion charge is considered, it will mean added expense to motorists.

In this regard, Dr Menendez explained: “Pricing is a very effective economic tool to change the demand. However, we all typically hate the idea of paying more for something. Thus, adding more flexibility when it comes to working hours or mobility options would allow some people to circumvent the congestion fees.”

For instance, Dr Menendez continued, “implementing flexible working hours can allow some commuters to avoid the higher fees during peak hours. Adding competitive forms of alternative transportation can induce some drivers to switch modes. Similarly, providing discounts for cars with multiple occupants can encourage people to carpool, taking a few cars off the road.”

Will congestion charge work the same way as Salik?

There are different flavours of congestion charge, noted Dr Menendez — although, in principle, congestion fee works the same way as Salik.

“With congestion charges, prices are typically variable and they go up when the demand is high (at peak hours). This encourages drivers to change either their departure time, their route, or their mode of transport,” she noted.

Urban planner and architect Aileen Llagas is amenable to implementing congestion charge. She noted minimal congestion charge would discourage motorists from driving during peak hours. “As an example, when Stockholm introduced congestion charges in 2006, that took away more than 22 per cent of cars from the roads, and vehicle emissions dropped by as much as 15 per cent,” she noted.

Llagas also underscored congestion charge must come hand-in-hand with encouraging carpooling and creating high-occupancy vehicle lanes to reduce the reliance on individual cars.
