South Africa’s sluggish transport system could find new momentum through digitalisation and sustainable investment, says transport economist Dr Olebogeng Baikgaki of the North-West University (NWU).

He argues that integrating digital technologies such as artificial intelligence (AI), the Internet of Things (IoT) and electric vehicles into transport planning could revolutionise mobility and reduce carbon emissions.

“The transport sector is one of the largest contributors to global CO₂ emissions,” says Dr Baikgaki from the NWU’s Faculty of Economic and Management Sciences. “Adopting digital and sustainable transportation is essential to combat climate change while stimulating economic growth.”

His comments coincide with Transport Month in South Africa, whose public transport system is struggling with inefficiencies and outdated infrastructure.

Develop a clear national digital strategy for transport

AI-based logistics can optimise transport routes, predict maintenance needs and improve freight efficiency, he notes. For instance, real-time data analysis allows operators to minimise fuel consumption and reduce environmental impact. Similarly, the adoption of electric and autonomous vehicles can decrease dependence on fossil fuels while improving road safety and efficiency.

However, Dr Baikgaki cautions that South Africa must overcome infrastructure and policy challenges to realise these benefits. Inadequate internet access, outdated regulations, and limited data literacy hinder progress toward digital transformation. “Without a clear national digital strategy for transport, South Africa risks falling further behind,” he says.

He says the logistics and freight industries, vital to South Africa’s economy, are being reshaped by automation, smart supply chains and data-driven decision-making. Intelligent logistics systems can enhance supply chain visibility from manufacturing to delivery, creating new efficiencies in cost and time management.

Create walking and cycling infrastructure

Beyond technology, Dr Baikgaki stresses the importance of environmental stewardship. “Sustainable mobility should be at the heart of policy planning,” he says. “That means transitioning to low-carbon models, expanding public transport, and integrating walking and cycling infrastructure.”

As global cities move toward sustainable transport systems, South Africa’s urban areas, home to over 65% of the population, must prioritise cleaner, smarter and more inclusive mobility networks. “Digitalisation offers South Africa a chance not only to modernise its transport sector but also to create a greener and more resilient economy,” Dr Baikgaki concludes.
