Local authorities from across Europe are joining JUST STREETS as Twin Cities.

Through a flexible, collaborative learning programme - combining peer exchange, expert insights and hands-on workshops - each city will build its own roadmap toward inclusive and climate-resilient urban mobility, adapting proven street transformation strategies to their own local context.

Selected from 68 applications, 12 cities are taking part in the programme, running from February 2026 to June 2027.

Adana, Türkiye

Adana, Türkiye's fifth-largest city, lies in the fertile Çukurova plain in the Mediterranean Region. With 1.9 million residents, it is a vital agricultural, industrial and commercial hub, famed for cotton, citrus, textiles and cuisine, with roots over 8,000 years old as a Cilician trade centre.

Adana struggles with rapid urbanisation causing traffic congestion, car dependency and air pollution. The city features the Adana Metro light rail, buses, Çukurova Airport and rail links, and promotes sustainable mobility through integrated planning and better public transport.

Antwerp, Belgium

Antwerp, Belgium's second-largest city and a major European port, faces complex challenges related to mobility, inclusive public space and climate adaptation. These challenges are amplified by rapid urban growth, high traffic volumes and increasing climate risks such as frequent flooding and prolonged droughts. 

To address these issues, Antwerp has developed several strategic frameworks including the Climate Plan 2030, Water Plan, Routeplan 2030 (Mobility Plan) and Greening Strategy. While these plans set ambitious goals, the real challenge lies in translating vision into practice and implementing systemic solutions at scale.

Città di Bra, Italy

The Municipality of Bra is a small city of around 30,000 inhabitants located in Northern Italy, between the famous hills of Langhe and Roero, not far from Turin. Due to its geographical position, there is a high level of traffic and an increasing level of air pollution.

Despite this, in recent years significant efforts have been made to develop slow streets suitable for both cyclists and pedestrians in order to preserve air quality and stimulate physical activity. Local policy aims to continue in this direction, making the city centre even more sustainable, green and inclusive.

Brussels Capital Region, Belgium

Brussels-Capital Region is a dense, diverse urban region and the administrative heart of Europe. Its mobility and urban planning strategies focus on reclaiming public space, improving air quality and reducing car dependency.

Through initiatives like the Regional Mobility Plan 'Good Move' and the Low Emissions Mobility Roadmap, Brussels promotes multimodal mobility, expands cycling and pedestrian infrastructure, enhances public transport and shifts toward low-emission and shared vehicles. The region aims to build a more accessible, sustainable and people-centred urban environment.

Bucharest District 1, Romania

District 1 is one of the most dynamic areas of Bucharest, combining dense residential neighbourhoods, major public institutions, green spaces and key metropolitan transport corridors. Despite its economic vitality, the district faces significant mobility and urban planning challenges including high car dependency, congestion, fragmented pedestrian and cycling infrastructure and limited accessibility for vulnerable groups.

According to the Bucharest Sustainable Urban Mobility Plan (PMUD 2016–2030), a transition toward people-oriented streets, integrated transport systems and climate-resilient public spaces is essential for improving quality of life.

Bursa, Türkiye

Bursa is Türkiye's fourth-largest city and a rapidly growing industrial and cultural centre with over 3.2 million residents. While the city has strong strategic plans for sustainable mobility, increasing car dependency, fragmented walking and cycling networks and climate risks such as heatwaves and flooding continue to shape daily life.

In recent years, Bursa has begun piloting more inclusive and people-centred street transformations through tactical urbanism, school street initiatives and climate-sensitive public space design, aiming to shift toward safer, low-carbon and more equitable mobility for all residents.

Cascais, Portugal

Cascais is located on Portugal's west coast, covering 97.4 km². The municipality values its rich natural and cultural heritage: one-third of its territory is protected landscape, and its 30 km coastline provides significant environmental and recreational benefits.

Cascais is a national pioneer in sustainable urban planning, integrating climate action, energy transition and mobility into a long-term vision. The Urban Mobility Action Plan and Municipal Climate Action Plan guide these efforts. A key initiative is MobiCascais, an integrated system connecting public transport, shared mobility, parking management and electric vehicle charging infrastructure through a single digital app.

Iasi, Romania

Iași is Romania's second-largest city by urban area, with approximately 300,000 city-proper residents and over 450,000 in the metropolitan area, and its cultural and historical capital. Located in northeastern Romania at the European Union's eastern border, the city hosts over 60,000 students across five public universities, generating intense daily mobility demand. Public transport relies on a tram network operational since 1900 and a bus fleet serving over 140,000 passengers daily.

Currently, Iași is investing in fleet modernisation — including 18 new electric trams procured in 2024 — while working to reduce car dependency and expand sustainable urban mobility options across both its dense urban core and surrounding metropolitan communities.

Lviv, Ukraine

Lviv is a historic, compact yet growing city in western Ukraine. The central part of the city has a well-preserved, dense urban fabric, while modernist-style development dominates the city's periphery.

Lviv has a strong tradition of walking and public transport use. Its mobility system is anchored by trams, trolleybuses and buses, although car use is steadily increasing. Current urban planning priorities focus on improving public transport services, accessibility, traffic calming, cycling infrastructure and street redesign.

Maia, Portugal

Maia is located in Portugal's Northern Region and part of the Porto Metropolitan Area. It benefits from a geostrategic location due to the presence of Francisco Sá Carneiro International Airport on its territory and its geographical proximity to the Port of Leixões. Maia's territory has a total area of 82.9 km² and a population of 134,977 inhabitants, composed of 10 parishes.

The municipality has seen individual car transport intensify - a result of increasing motorisation rates not only in Maia but across most of the country. Maia is currently developing a new Sustainable Urban Mobility Plan (SUMP) to make urban mobility more inclusive, cleaner and sustainable, and ultimately improve the quality of life of its citizens.

Swansea, Wales

Swansea is Wales' second-largest city, located on the coast of south-west Wales. With a population of 250,000, the city is one hour from Wales' capital Cardiff and three hours from London. Swansea was heavily damaged during the Second World War due to its status as a key port and centre of heavy industry, resulting in much of the centre being destroyed.

The post-war rebuilding of the city coincided with a preference for car-oriented urban planning. This, coupled with the city adapting to its post-industrial role, has resulted in Swansea becoming a decentralised city and a place where many residents feel they need to own a car.

Venice, Italy

The City of Venice (approx. 252,000 inhabitants), including its mainland areas such as Mestre and Marghera, is the capital of the Veneto Region.

Over the last decade, Venice has significantly improved its sustainable transportation infrastructure: the bike lane network expanded from 4 km in 1992 to 195 km in 2024, and shared mobility services including bike sharing, car sharing and e-scooter sharing have been introduced.

The local SUMP is currently under review, while the metropolitan SUMP was adopted in 2022.
