Istanbul has made many strides in sustainable transport in recent years. Through a world class bus rapid transit (BRT) system and pedestrianization of public spaces, Istanbul is working to improve transport access, health, road safety, and decrease greenhouse gas emissions and road congestion. These are six of the most important facts you may not know about sustainable transport in Istanbul:
World class BRT ridership
Istanbul began implementing its BRT system, Metrobüs, in 2007. According to EMBARQ’s 2013 Social, Environmental, and Economic Impacts of BRT Systems study, about 600,000 people use Metrobüs each day. This number is likely growing, as Hayri Baracli, previous Director General of Istanbul Electric Tram and Tunnel Company (IETT) more recently stated that the Metrobüs carries 800,000 people daily, making it among the more heavily used BRT systems in the world. The Metrobüs is particularly important in providing access to transport for lower- and middle-income groups in Istanbul, who make up thelargest proportion of its users.
Metrobüs is one of the most cost-effective BRT systems in the world
According to the previously mentioned study, the total net present benefits of the Metrobüs system are worth TL 11.4 billion (US$ 6.4 billion), and the benefits exceed the costs by a ratio of 2.8 to 1. This cost-benefit analysis accounts for the public and private costs to society as a whole. For example, benefits include savings in travel time for BRT users and others, improved road safety, and decreased exposure to local air pollutants, while costs include infrastructure, equipment, maintenance, and operations costs. By shifting from other modes of transport, Metrobüs users can save 28 days per year in reduced travel time.
Metrobüs reduces greenhouse gas emissions
By reorganizing and consolidating informal transit and conventional buses, Istanbul’s Metrobüs system is estimated to reduce CO2 emissions by 167 tons per day, and more than 240 ton-liters in total.

Pedestrianization of public spaces has helped business
Between 2010 and 2012, Istanbul pedestrianized 295 streets, barring access to all vehicles. This has had a wide range of benefits, including improving safety and access to public transport by foot and decreasing air pollution within the pedestrianized areas. Further, EMBARQ Turkey’s survey of business owners and managers within the pedestrianized areas found that 78% of respondents said they were pleased or very pleased with pedestrianization, and 56% expected their sales to increase. After witnessing the positive impact of pedestrianization in the region, the Laleli Industrialists’ and Businessmen’s Association (LASIAD) invested alongside the municipal government in the pedestrianization of the At Laleli and Üst Laleli areas.
Strong demand for improved cycling infrastructure
According to a survey conducted by EMBARQ Turkey, 83% of respondents indicated that safe bike lanes should be implemented for all bikers. Istanbul is working towards an ambitious goal of having 1,000 km (650 miles) of bikeways as an integrated transport mode by 2023. As Istanbul improves cycling infrastructure, it is crucial for planners to choose routes carefully in order to integrate biking with other transport modes, define goals and increase biking’s mode share.
