Electric and non-motorised three-wheelers, such as rickshaws, are a controversial yet major part of the traffic in countries such as Bangladesh. The latest report to be published by HVT explores the potential issues that these slow-moving vehicles pose, and the extent of the challenges. The report then lays out clear and practical guidelines to provide solutions to policy makers and infrastructure planners for the near and long-term.
Like many countries in the region, Bangladesh has seen substantial urbanisation and population growth in recent years, creating huge pressures on infrastructure to keep up. Cities, like the capital city Dhaka with a population of more than 15 million people, experience intense daily travel demands and those moving about the cities face challenges including congestion, unpredictable and delayed journeys, uncomfortable transport options and worsening air pollution.
Many people – especially those with limited income – look to the electric and non-motorised three-wheeler vehicles to meet their needs. They form a major part of the traffic, as much as 80% in some cities, but are a controversial part of the infrastructure with accusations of a lack of safety and bad environmental records.
Existing planning guides often focus on motorised traffic and overlook the very specific needs of the three-wheeler slow-moving vehicles (Tri-SMVs) but these latest guidelines from the Islamic University of Technology look to bridge the gap.
The guidelines focus on several key improvements including emphasising the mitigation of hazards such as potholes, uneven surfaces, and inadequate signage, aiming to reduce accidents and improve ride quality for Tri-SMVs. The recommendation for dedicated lanes and reinforced shoulders ensures the safe and efficient movement of these vehicles, which are vital for both urban and rural mobility.
In terms of roadside safety, the guidelines advocate for improved features like customised barriers and clear signage to protect Tri-SMV users from fixed and transient hazards. It also highlights the importance of tailored traffic calming measures and specific speed regulations to manage the unique dynamics of Tri-SMVs, thereby enhancing overall road safety.
The guidelines offer a framework adaptable to other countries, especially in the Global South where similar transportation challenges exist. The ‘Technical Recommendations for Road Design Considering Three-Wheeler Slow-Moving Vehicles’ represents a crucial step towards creating inclusive road infrastructure that enhances the safety and comfort of Tri-SMV users.
