Solving the problem of congestion is usually a top priority for city authorities, who note that congestion not only causes air pollution, but also decreases quality of life and imposes significant economic costs, especially in rapidly growing cities. Although different cities have developed different solutions for dealing with the problem of congestion, few have successfully solved it. Mostly cities come up with ad hoc measures for dealing with congestion, like constructing more roads, bridges and highways, which paradoxically spur more car ownership and, hence, more congestion.
To date, the most effective measure to reduce congestion is something called congestion pricing, a type of road pricing put in place during specific times and locations, namely the most congested areas during peak times like rush hour. The pricing scheme is used to encourage travelers to shift to other travel times, routes and modes of transit. Congestion charging rates are flexible and can differ according to the type of motor vehicle, and can either be a flat rate or updated regularly to reflect the prevailing traffic conditions.
Although congestion pricing is not a new concept (it was first implemented in Singapore in 1975), it has not been widely adopted due to various political, technical and economic reasons. However, the positive results from congestion pricing are considerable, as seen in the cities that have implemented this pricing policy. London, Singapore and Stockholm all use congestion pricing as a tool for fighting congestion, experiencing significant reductions in traffic during peak hours, reduced travel time, lower transport emissions, including CO2, as well as increased traffic speed, higher levels of safety, and greater revenue for cities, which can be used to improve mass transit. Traffic volume decreased by more than 50% and 25% when pricing was first introduced in Singapore and Stockholm respectively, while congestion dropped by 30% within the charging zone in London. Since travel time lost in congestion and other associated externalities are often not captured and paid by motorists, that is, the ones who cause the problems, the implementation of an effective pricing policy will be able to internalize such external costs.
It’s also important to note that access and mobility should never be denied. So it’s crucial to complement a congestion pricing scheme with a public transport system that is affordable, efficient, safe, clean, and comfortable so that people have an alternative way for arriving at their destination.

I’m glad this is working in London though I just wonder if instead of using all the technology required to make congestion charging work, would it of been easy to raise parking taxes significantly?

That’s an interesting point. I would be curious to see how much London and other cities have spent implementing their system. With technologies like gps becoming more ubiquitous, there is the potential of putting these in cars and then charging based on where a car travels. This would certainly be a lower cost than using on-street cameras which are also ugly.

The raising of parking taxes or fees should serve as a complementary measure to increase the variable cost of driving, which will ultimately influence driving behavior. A first step could be to eliminate curb side parking, in order to decrease the number of cruising vehicles. The development of GPS technology in congestion pricing is being conducted in several cities. Current technologies might still not be perfect enough to relay real time information to drivers, provide alternative routes that are not congested at a particular time instantaneously, and to charge different prices according to the time, state of congestion and street segment all at once, but this should change in the near future. Electronic road pricing systems are no doubt expensive, but given that the first congestion pricing system in the world started manually, good congestion pricing schemes need not require expensive technologies.

[...] Invest in Mass Transit: Americans are flocking to mass transit in ever greater numbers. At 10.3 billion trips last year, mass-transit ridership in the United States is at its highest level since 1957. To match this growing demand, cities should invest money to maintain and expand their mass-transit systems. One practical way to do this is to charge car drivers for using the most congested roads and use this revenue to fund mass-transit projects and operations. London, Singapore, and Stockholm all have wildly successful congestion-pricing programs that are, counter to conventional wisdom, popular among residents. Mass transit does not necessarily mean rail. Cities can also thrive with low-cost, fast implementation systems like bus rapid transit, which has been done in Los Angeles, Ottawa, Sidney, Mexico City, Curitiba, and Bogotá. [...]
