Some argue that the most effective way to reduce the number of vehicles on city roads is to introduce toll roads and raise fuel prices. Others, however, believe that it is the government’s responsibility to provide better public transport. I side with the latter view, because authorities owe their citizens affordable and convenient infrastructure in return for the taxes they pay, and because investing in public transport benefits both the environment and the mobility of less affluent residents.
Those who favour higher driving costs argue that if car use becomes more expensive, fewer people will choose to drive, and congestion will ease as a result. In theory, this is a direct and efficient solution: pricing changes behaviour. In practice, however, most car journeys are not optional. Parents taking children to school, people with disabilities, and workers on early shifts often have no realistic alternative, so higher fuel prices and tolls function less as a deterrent than as a financial penalty. In addition, as drivers switch to buses and trains, demand may outstrip supply, producing overcrowding and longer waiting times rather than the smooth service that would genuinely persuade people to leave their cars at home. While such taxes do generate revenue, in most countries this money disappears into general budgets instead of being reinvested in transport.
A far more effective approach is to develop public transport, particularly in city centres, where the problem is most acute. Historic centres with narrow streets and dense construction simply cannot accommodate growing traffic: roads cannot be widened, and no congestion charge can change the fact that people still need to travel there for work, healthcare, and shopping. A modern metro system or a well-connected tram and bus network solves this problem at its root, because it moves large numbers of people without occupying scarce road space – a single underground train can replace hundreds of cars. London’s expansion of the Underground and the introduction of tram lines in cities such as Strasbourg illustrate how central congestion falls once a credible alternative exists. The benefits extend further: affordable fares keep lower-income residents mobile and economically included, while reduced car use lowers carbon emissions and improves urban air quality.
In conclusion, while raising the cost of driving may ease congestion to some degree, it penalises those with no alternative and does not address the underlying shortage of road space. Developing public transport, especially in city centres, is a more sustainable and socially fair solution.
