The Growing Importance of Public Transport in UK Cities

Public transportation is the lifeblood of urban economies, connecting people to jobs, education, healthcare, and leisure. In the UK, the quality and reach of bus, tram, and rail networks directly influence everything from air quality and economic productivity to social equity. Over the past two decades, the devolution of transport powers to city-region mayors has reshaped how public transport systems are planned, funded, and delivered. Mayoral policies now sit at the heart of efforts to modernise ageing infrastructure, integrate different modes of travel, and meet ambitious net-zero carbon targets. Understanding the influence of these elected leaders is essential for anyone following urban development, transport planning, or local government reform.

The role of a mayor is not merely ceremonial. In combined authorities such as Greater Manchester, the West Midlands, and the Liverpool City Region, mayors hold statutory powers over transport budgets, franchise agreements, and strategic planning. This authority gives them the unique ability to set a vision for mobility and then back it with political capital and financial resources. However, the relationship between mayoral policies and actual improvements is complex, shaped by national funding cycles, political negotiations, and the practical challenges of retrofitting transport networks in dense urban environments.

How Mayoral Powers Shape Transport Policy

The modern mayoral system in England was established through the Local Democracy, Economic Development and Construction Act 2009 and subsequent devolution deals. These deals transferred significant transport responsibilities from central government to combined authorities, each led by a directly elected mayor. The mayor controls the transport budget for their region, appoints board members to transport operators like Transport for London (TfL) or Transport for Greater Manchester (TfGM), and proposes long-term strategies that must be approved by the combined authority cabinet. This structural shift has given city-regions the tools to tailor transport investments to local needs rather than relying on Whitehall directives.

Devolution and Combined Authorities

Since 2014, combined authorities have been created in Greater Manchester, the West Midlands, Liverpool City Region, South Yorkshire, West Yorkshire, the North East, and Tees Valley. Each has a mayor with specific transport powers. For example, the Mayor of Greater Manchester controls the bus franchising system, the Metrolink tram network, and local rail stations. The Mayor of the West Midlands oversees the West Midlands Metro tram lines and bus priority schemes. These powers are not uniform; some mayors have greater control over local rail services than others, and funding still often depends on central government grants. Nevertheless, devolution has allowed mayors to pursue policies that are more ambitious and locally responsive than those of the previous county council model.

Funding Streams and Investment Decisions

Mayors influence public transport improvements through two main mechanisms: central government funding pots and locally raised revenue. The Transforming Cities Fund, City Region Sustainable Transport Settlements, and Levelling Up Fund are major sources of capital investment. Mayors lobby the Treasury for these allocations and decide how to spend them within their region. For instance, the West Midlands received £1.05 billion through the City Region Sustainable Transport Settlement in 2022, which the mayor directed towards extending the Metro, building new bus routes, and improving cycle infrastructure. Congestion charges, workplace parking levies, and fare revenue also provide direct funding streams that mayors can adjust through policy decisions. The ability to raise and allocate these funds is a powerful tool for driving transport change.

Case Studies: Mayoral Impact Across UK Cities

Examining specific cities reveals how mayoral policies have produced tangible improvements in public transportation, as well as the challenges that remain.

London: Congestion Charging and the Oyster Legacy

The Mayor of London has long held the most extensive transport powers in the UK. Ken Livingstone introduced the Congestion Charge in 2003, reducing traffic in central London by 30% and generating funds reinvested into bus services. Boris Johnson oversaw the introduction of the New Bus for London "Routemaster" and the extension of the Crossrail project (now the Elizabeth line). Sadiq Khan has pushed for the Ultra Low Emission Zone (ULEZ), expanded to cover all London boroughs in August 2023, significantly cutting nitrogen dioxide levels. The Oyster card system, launched under Livingstone, remains a global benchmark for integrated smart ticketing. These policies—enabled by the mayor’s control over TfL—demonstrate how consistent mayoral leadership can transform urban mobility over decades. London’s transport strategy continues to prioritise walking, cycling, and zero-emission buses.

Manchester: Bus Franchising and Clean Air Zones

Greater Manchester was the first region outside London to gain bus franchising powers through the Bus Services Act 2017. Mayor Andy Burnham has used these powers to re-regulate bus services, which were previously run by private operators with little local control. In 2023, the first franchised bus routes launched under the Bee Network, bringing simpler fares, better frequencies, and integrated ticketing with the Metrolink tram system. The mayor also proposed a Clean Air Zone for Greater Manchester, though it was delayed due to concerns about economic impacts on businesses. This example illustrates how mayoral policies must balance environmental goals with local economic realities. Transport for Greater Manchester provides detailed information on the Bee Network rollout.

Birmingham: Tram Expansion and Station Renewal

West Midlands Mayor Andy Street has focused on expanding the West Midlands Metro tram network. The Birmingham to Wolverhampton line has been extended through the city centre, and branches to Digbeth, the airport, and Walsall are under construction. Station upgrades at Birmingham New Street and Moor Street have improved interchanges between rail, tram, and bus. The mayor has also pushed for the construction of the Curzon Street railway station for HS2, which will act as a new transport hub. However, slow delivery of tram extensions and cost overruns have tested public patience. The mayor’s ability to secure long-term funding from central government has been critical—the West Midlands received over £1.5 billion in transport settlements between 2017 and 2023. West Midlands Combined Authority transport page outlines current projects.

West Yorkshire: Mayor’s Transport Strategy

West Yorkshire Combined Authority, led by Mayor Tracy Brabin, has adopted a Mayor’s Transport Strategy focused on creating an integrated, accessible, and zero-emission transport network by 2037. Key policies include the introduction of an affordable bus fare cap (£2 per journey in 2023), investment in electric buses, and the development of the Mass Transit system for Leeds—an ambitious light rail or bus rapid transit scheme that has been discussed for decades. The mayor has also prioritised improving cycle routes and walking paths. The challenge is funding: West Yorkshire has historically received lower per-capita transport investment than Manchester or London. Brabin has used her devolved powers to push for more equitable funding from central government.

Liverpool City Region: Merseyrail and Bus Reforms

Under Mayor Steve Rotheram, the Liverpool City Region has focused on extending the Merseyrail network to new destinations like Skelmersdale (via the new Headbolt Lane station) and the proposed Merseyrail Loop extending into Central Liverpool. The mayor introduced a bus franchising consultation in 2023, aiming to bring local bus services under public control by 2027. The city region has also launched a tap-and-go ticketing system for trains and buses, making travel simpler for passengers. Rotheram has been a vocal advocate for a London-style integrated transport system in the North West, with a single brand and fare structure. The Liverpool City Region Combined Authority’s transport strategy details these plans.

Policy Tools: From Congestion Charges to Smart Ticketing

Mayors have a range of policy instruments at their disposal to improve public transportation. Understanding these tools helps explain why some cities succeed where others struggle.

Zonal Pricing and Integrated Fares

Integrated ticketing systems allow passengers to use one card or app across buses, trams, and trains. London’s Oyster card and contactless payment system set the standard. Mayors in Manchester, Liverpool, and the West Midlands are now introducing similar systems. For instance, the Bee Network in Manchester uses a single contactless fare cap, ensuring passengers never pay more for multi-modal journeys than a single day travel card. These systems require complex back-end integration between operators, but the result is higher ridership and reduced congestion.

Low Emission and Clean Air Zones

Air quality is a major public health concern, and mayors have used their powers to impose charges on polluting vehicles. London’s ULEZ, Birmingham’s Clean Air Zone (introduced in 2021), and Manchester’s delayed scheme are examples. The revenue from these zones is often ring-fenced for public transport improvements, such as subsidising electric buses or retrofitting older vehicles. Critics argue that they penalise low-income drivers, but mayors defend the policies by pointing to reduced hospitalisations for respiratory conditions. The balance between environmental ambition and social equity remains a contentious issue in mayoral transport policy.

Real-Time Information and Digital Integration

Smartphone apps and real-time bus arrival displays have become expected by passengers. Mayors have invested in open data platforms that allow third-party developers to create journey planners. Transport for West Midlands has an open data portal, while TfL’s API is used by apps like Citymapper and Google Maps. Mayors also promote dynamic capacity management—using sensors to adjust bus frequency based on demand. These digital tools improve the customer experience without requiring major infrastructure spending.

Challenges in Implementing Mayoral Transport Policies

Despite the potential, mayors face significant obstacles in delivering transport improvements. Understanding these challenges is essential for realistic assessments of policy impact.

Funding Gaps and National Government Relations

Mayoral budgets are heavily dependent on central government grants. The Treasury often imposes strict spending conditions, limiting flexibility. For example, the City Region Sustainable Transport Settlements come with five-year spending profiles that may not align with the mayor’s priorities. Infrastructure projects like tram extensions often face severe cost overruns—the Metrolink Trafford Park line, for instance, required additional funding from the Greater Manchester mayor’s office. Mayors must also lobby for large capital projects, creating a complex relationship with ministers. A change in national government can shift funding priorities, as seen when the Conservative government delayed Manchester’s Clean Air Zone.

Political Opposition and Voter Expectations

Mayors are elected by popular vote, often from a base of urban supporters who favour public transport investment. However, unpopular measures like road closures or congestion charges can generate backlash from suburban voters and businesses. The ULEZ expansion in London was challenged in court by several boroughs, and the Mayor faced a by-election in Uxbridge in 2023 largely fought on the issue. Mayors must carefully calibrate their policies to maintain electoral support while making difficult choices. The tension between ambitious long-term goals and short-term political pressures is a recurring theme.

Infrastructure Constraints and Planning Delays

Many UK cities have transport infrastructure that is decades old, designed for a different era. Adding new tram lines or bus lanes requires digging up streets, obtaining planning permissions, and coordinating with utility companies. The planning process can take years—Leeds’ Mass Transit project was first proposed in the 1940s and remains on the drawing board. Mayors often blame the slow pace of delivery on central government’s procurement rules, which can cause significant delays. Heritage regulations, such as protecting listed buildings or conservation areas, can also block modernisation projects.

Opportunities for Innovation and Collaboration

Despite the obstacles, mayors are finding creative ways to accelerate transport improvements.

Public-Private Partnerships

Where public funds are limited, mayors have turned to private capital for infrastructure delivery. The West Midlands Metro extension to Digbeth is partly funded by a developer contribution linked to new housing and commercial space. In London, Crossrail was financed through a mix of government grants, borrowing, and a supplemental business rate on commercial property. Liverpool City Region is exploring a similar model for its proposed Merseyrail Loop. These partnerships can speed up delivery but require transparent contracts and risk-sharing arrangements.

Community Engagement and Co-Design

Mayors now routinely conduct public consultations on transport changes, using online surveys, town hall meetings, and social media. The West Yorkshire Combined Authority’s “Let’s Talk Transport” campaign gathered over 10,000 responses that shaped the Mayor’s Transport Strategy. In Manchester, the Bee Network branding was developed through focus groups with passengers. Engaging local communities helps build support for controversial measures like reduced road space for cars. However, consultation fatigue is a risk, and mayors must ensure they act on the feedback they receive.

Leveraging Data for Better Mobility

Transport data is a powerful tool for optimising bus timetables, predicting delay hotspots, and planning network expansions. TfL publishes over 800 datasets on its open data portal, which independent researchers have used to improve journey predictions. Mayors in smaller city-regions are investing in data analytics units. For example, the South Yorkshire Mayoral Combined Authority uses real-time passenger counter data to adjust bus frequencies on popular routes. This data-driven approach allows mayors to make evidence-based decisions rather than relying on intuition or lobbyists.

The Future of Mayoral Leadership in Public Transport

Looking ahead, mayoral policies will continue to evolve in response to climate targets, demographic shifts, and technological change.

Net Zero Commitments and Green Transit

Nearly all mayors have declared climate emergencies and set net-zero targets for their regions. This includes switching bus fleets to zero-emission vehicles (electric or hydrogen), expanding tram networks to replace car journeys, and imposing tighter emission zones. Manchester aims to run a zero-emission bus fleet by 2030, while London’s entire bus fleet will be zero-emission by 2034. Mayors are also encouraging active travel through cycle highways and pedestrianised zones. These policies align with national net-zero goals, but they require heavy upfront investment in new vehicles and charging infrastructure.

Accessibility and Inclusive Design

Public transport must work for everyone, including older people, disabled users, and those with buggies or heavy luggage. Mayors have introduced low-floor buses, step-free access at tram stops, and audible announcements on trains. The Mayor of London has funded the “Step Free Access” programme, which has increased the number of Tube stations with step-free access from 66 in 2016 to over 100 by 2024. New stations are designed to universal standards. However, many older stations remain inaccessible, and mayors face funding constraints for retrofits.

The Role of Technology in Seamless Journeys

Mobility-as-a-Service (MaaS) apps that combine public transport, bike-sharing, and ride-hailing into a single platform are being piloted in several UK cities. The West Midlands launched a MaaS trial called “Whim” in 2020, and Transport for Greater Manchester is developing a Bee Network app with journey planning and payment integration. Mayors see MaaS as a way to reduce car dependency, but success depends on integrating multiple operators and convincing users to change travel habits.

Conclusion: Mayors as Catalysts for Change

Mayoral policies have proven to be a powerful force for public transportation improvements in UK cities. From London’s congestion charging and world-beating ticketing system to Manchester’s bus franchising and Birmingham’s tram expansions, elected mayors have used their devolved powers to push through transformative changes that would have been difficult under the old county council structures. The results are not uniform; funding constraints, political opposition, and infrastructure inertia remain real barriers. But the trend is clear: mayors are the key decision-makers, and their policies directly shape the mobility of millions of urban residents.

As cities grow and climate pressures mount, the need for strong, accountable local leadership in transport will only intensify. The next generation of mayors will have to balance environmental ambitions with economic realities, invest in digital innovation, and ensure that transport improvements reach every community. The evidence so far suggests that when mayors are given the powers and resources to act, they can deliver public transport networks that are more efficient, more inclusive, and more sustainable. The influence of mayoral policies on public transportation is not a footnote in urban governance—it is the central story of how UK cities are remaking themselves for the twenty-first century.
