This report analyzes the growing problem of road congestion in Australia, focusing on its economic and social consequences. The introduction highlights the prevalence of congestion in major cities like Melbourne, Sydney, and Brisbane, citing statistics on increased travel times and declining average speeds. The report then delves into the economic and social issues, such as increased emissions, damage to public health, rising business costs, and the overall negative externality on the Australian economy. An economic model using a graphical exposition is used to illustrate the concept of negative externalities and deadweight loss. The report then examines policies to reduce congestion, including the imposition of congestion charges/taxes, improvements in transport substitutes, and building more roads. Each policy is analyzed with graphical representations to demonstrate its potential impact on market equilibrium and social welfare. The conclusion summarizes the findings, emphasizing the need for policy intervention to mitigate the negative effects of road congestion on the environment, society, and the economy.
