Traffic and pollution from vehicles

Traffic and pollution from vehicles have become huge problems, especially in urban areas. This problem can be solved by increasing the price of petrol, but in long term, high fuel costs are unlikely to limit the number of drivers. Furthermore, increasing the price of petrol will also affect public transport costs. To solve this problem, it is necessary to develop technologies that use clean fuels such as producing electric cars that help run both quieter and cleaner. The application of this new technology will help improve air quality. However, this technology also cannot solve traffic jams. Therefore, to reduce pollution and traffic in the long term, it is necessary to strengthen the development of public transport services.
