Reduce congestion. Therefore reduce time wasted and reduce costs for business
Reduce pollution. Fewer cars will lead to less pollution.
Make city centres more attractive for pedestrians and cyclists, which will help increase quality of life.
Raise revenue. The money from congestion charge can be spent on other forms of public transport and increasing alternatives to driving.
Make Drivers pay social cost of driving. Driving in city centres incurs significant external costs on the rest of society. The main external costs include congestion, pollution and accidents. Congestion is estimated to cost the UK economy over £20bn a year in terms of extra costs for business (time wasted) Driving already incurs taxes, most notably, petrol tax. However, petrol tax doesn’t discriminate for where congestion is worst. Therefore, councils could place a congestion charge on driving into a certain area at busy times
Reduce Journey Time. This is good for business, but also helpful for emergency services in getting to serious injuries quicker.
