Establishing a sustainable transport system is crucial for economic growth and the rapid movement of goods and people while reducing the environmental impacts of transport and improving quality of life in developing countries. However, countries frequently face several challenges related to transport, including inadequate infrastructure, rapid urbanization, and limited resources. On World Sustainable Transport Day, we launched a discussion regarding the sustainability of transport systems with several international experts. Check out their opinions below.
Key Takeaways:
- According to UN stats, only half the world’s urban population has convenient access to public transport
- Developing countries face significant challenges related to transport infrastructure including a lack of essential road networks, bridges, ports, and public transport systems which stifle economic growth and restrict access to crucial services
- By reducing the number of vehicles on the road, public transport contributes to reduced congestion and lower pollution levels
DevelopmentAid: What are the most pressing challenges related to transport faced by developing countries and how do these challenges differ from those in developed nations?

“Transport challenges in developing countries differ from those in developed nations due to a variety of factors, including infrastructure limitations, economic constraints, population growth, and urbanization patterns. Here are some of the most pressing transport challenges faced by developing countries:
- Inadequate infrastructure: developing countries often lack the necessary road networks, bridges, ports, and public transport systems. Poorly maintained or nonexistent infrastructure hinders economic growth and limits access to essential services.
- Traffic congestion: rapid urbanization in developing countries leads to congested roads and longer commute times. The lack of effective public transport alternatives contributes to this problem.
- Safety concerns: Developing countries often have higher rates of traffic accidents and fatalities due to poor road conditions, poor enforcement of traffic laws, and inadequate emergency response systems.
- Public transport deficiencies: public transport systems may be underdeveloped, unreliable, or inaccessible to a significant portion of the population. This forces people to rely on private vehicles, exacerbating congestion and pollution.
- Lack of funding: developing countries often struggle to secure the funding required for transport infrastructure development and maintenance leading to a perpetuation of existing challenges.
- Shadow economy (informal transport sector)ts: in many developing countries, a significant portion of transport services is provided by informal or unregulated operators, leading to issues of safety, reliability, and fairness.
- Access to rural areas: providing transport services to remote or rural areas can be challenging and costly, leading to isolation and limited economic opportunities for these regions.
- Technology gaps: developing countries may lag behind in adopting modern transport technologies, such as intelligent transport systems, which can improve efficiency and safety.”

“Developing countries grapple with multifaceted transport challenges such as dilapidated or scant infrastructure, overwhelming urban migration, and resource scarcity. Unlike developed nations, where infrastructural frameworks are usually stable and regulatory policies well-established, developing countries may lack the financial means, technical expertise, and governance mechanisms to systematically address these challenges. For instance, whereas advanced countries focus on optimizing or innovating within existing robust transport networks, developing nations are often still working to establish basic, reliable, and accessible transit infrastructures to ensure their economic development.”

“According to the World Health Organization (2021), developing nations constantly grapple with pressing transport issues due to underinvestment in emerging urban developments. As a result, some concerns are a deficient physical infrastructure, limited access to efficient transport, exposure to congestion, and lack of safety.”
