Street design with express lanes for buses

Freiburg in southern Brazil is often regarded as the "greenest city on Earth". The city has implemented a range of measures to tackle air pollution, including an innovative street design with dedicated express lanes for buses. This measure has been highly effective in reducing both air pollution and traffic congestion.

The express bus lanes are an integral part of Freiburg's transportation network, providing efficient and seamless travel across the city. These lanes are typically located on major roads and highways, ensuring that buses have a clear and uninterrupted path to their destinations. By prioritising bus transportation, the city encourages the use of public transport, reducing the number of private vehicles on the roads.

The design of these express lanes is well-thought-out and optimised for bus transportation. They are typically characterised by their width, allowing for larger buses with increased passenger capacity. This not only improves the efficiency of the bus service but also makes it a more attractive option for commuters. The lanes are clearly marked and often feature designated bus stops or stations, enabling quick and convenient boarding and alighting for passengers.

To further enhance the efficiency of the express bus lanes, Freiburg introduced a pre-payment system. This eliminates the need for bus drivers to issue tickets, reducing delays during boarding. The pre-payment system likely includes the use of bus cards, tokens, or mobile payment options, streamlining the boarding process and reducing the time buses spend at each stop.

The implementation of express lanes for buses has had a significant impact on Freiburg's transportation system and overall air quality. By prioritising bus transportation, the city has made public transport a more attractive and efficient option for commuters. As a result, there has been a notable shift towards public transport, with close to 70% of the city's population opting for buses and other forms of mass transit. This has directly contributed to the reduction of air pollution and traffic congestion, making Freiburg a leader in sustainable urban planning and a model for other cities aiming to improve their environmental performance.

Larger buses and pre-payment systems

Freiburg, often hailed as the “greenest city on Earth”, has implemented several measures to tackle air pollution. One of the key initiatives has been to encourage the use of public transportation, with almost 70% of the city's population opting for this mode of commute. To facilitate this shift, the city has introduced larger buses with increased capacity and a pre-payment system for faster boarding.

The introduction of larger buses has been a strategic move to accommodate more passengers, reducing the number of vehicles on the roads and, consequently, decreasing traffic congestion and air pollution. This initiative is complemented by the pre-payment system, which not only expedites the boarding process but also enhances the overall efficiency of the public transportation system.

The pre-payment system eliminates the need for bus drivers to issue tickets, streamlining the boarding process. This system not only saves time for both drivers and passengers but also contributes to the overall attractiveness of public transportation. By reducing the time spent at bus stops, the pre-payment system makes commuting by bus a more convenient and appealing option for residents.

The combination of larger buses and the pre-payment system has played a significant role in Freiburg's efforts to tackle air pollution. By encouraging a higher number of commuters to choose public transportation, the city has successfully reduced vehicle emissions and improved air quality. This approach underscores the importance of providing efficient, affordable, and eco-friendly alternatives to private transportation to create a more sustainable urban environment.

Increased green cover

Freiburg, often hailed as the “greenest city on Earth”, has taken several measures to tackle air pollution. One of the key strategies has been to increase its green cover. Here are some ways in which Freiburg has achieved this:

• Park Development: Instead of having just one park, Freiburg now boasts over 50 square meters of green space per person. This increase in green areas helps absorb pollutants and provides fresh oxygen, improving the overall air quality.
• Tree Planting Initiatives: The city has likely embarked on tree-planting initiatives, with native tree species being planted in parks, along streets, and in residential areas. Trees act as natural air filters, absorbing pollutants such as nitrogen dioxide and particulate matter while releasing oxygen, enhancing the air quality for residents.
• Green Roofs and Vertical Gardens: Freiburg could have encouraged the development of green roofs and vertical gardens on buildings. This approach not only increases the city's green cover but also provides insulation for the buildings, reducing their energy consumption and associated emissions.
• Green Corridors: Freiburg could have also developed green corridors, which are networks of green spaces and vegetation that connect different parts of the city. These corridors provide habitats for wildlife, promote biodiversity, and help purify the air by trapping pollutants and filtering the air as it moves through these green spaces.
• Community Gardens: The city may have also promoted the development of community gardens in neighborhoods. These gardens not only increase the green cover but also provide spaces for residents to grow their own food, fostering a sense of community and contributing to local food production.

By increasing its green cover, Freiburg is not only improving air quality but also enhancing the well-being of its residents, providing spaces for recreation and social interaction, and creating a more sustainable and resilient urban environment.

Low-cost public transport

Freiburg, Germany, has been hailed as one of the best examples of sustainable development. The city has implemented several measures to tackle air pollution, including improving its already low-cost and efficient public transport system.

One key strategy has been to make the city's public transport so attractive that people will choose it over cars. Freiburg has achieved this through various innovations. Firstly, the city redesigned its streets to include express lanes for buses, reducing travel time for commuters. Secondly, it introduced bigger buses with more capacity, making the system more efficient and comfortable for passengers. Another innovation is the pre-payment system, where passengers pay before boarding, eliminating the need for bus drivers to issue tickets and further speeding up the boarding process.

In addition to buses, Freiburg has invested in its railway system. In 1997, a new fleet of modern, air-conditioned railcars with low entrances was introduced, attracting more passengers. A regular schedule was implemented on the Breisgau S-Bahn in 1998, starting with one train per hour. However, due to increasing passenger numbers, the frequency soon had to be increased to every 30 minutes.

The improvements in Freiburg's public transport system have had a significant impact. The number of bicycle trips has tripled, public transport ridership has doubled, and the share of trips by automobile has declined from 38% to 32%. As a result, per-capita CO2 emissions from transport have decreased, even as the city has experienced strong economic growth.

Freiburg's approach to sustainable transport provides valuable lessons for other cities aiming to reduce air pollution and create more environmentally friendly urban environments.
