The high-tech transit system that might just be a fancy bus
In short: Autonomous Rapid Transit (ART) promises the capacity of a train with the flexibility of a bus. Guided by optical sensors and virtual tracks, these bi-articulated vehicles aim to revolutionize urban mobility. However, critics argue they may be more cosmetic than revolutionary, facing significant hurdles in reliability and infrastructure costs.
Developed by CRRC Zhuzhou Institute Co Ltd, ART was first unveiled in China in 2017. Despite being branded 'electric road' or 'digital rail', this technology functions as a bus with multiple sections steered via optical sensors instead of physical tracks. It requires a human driver to manage throttle and braking, though it features automated lane departure warnings, collision alerts, and route change authorization systems that analyze traffic to suggest detours.
The technology faces scrutiny regarding its "rapid" transit claims. While proponents highlight lower construction costs due to the lack of rails, researchers in 2021 found that the heavy alignment of wheels can create ruts and depressions in public roads. This may necessitate road reinforcements as disruptive as installing actual light rail. Furthermore, because they use rubber tires instead of steel wheels, ART vehicles experience higher rolling resistance, requiring more energy for propulsion.
Capacity and reliability remain contested points. In Auckland, studies suggested that while manufacturers claim high passenger densities, realistic capacity might only slightly exceed conventional bi-articulated buses. Additionally, several international trials have hit roadblocks: Indonesia's pilot was halted because the system could not operate fully autonomously, requiring manual intervention due to suboptimal braking and control systems. Meanwhile, Malaysia shelved a planned project in 2024 after finding ART unable to handle projected traffic flows efficiently.
Despite these challenges, global interest persists. From trials in Australia and New Zealand to proposed corridors in Brazil and Pakistan, the goal remains a middle ground between high-cost rail and low-capacity buses. The ultimate success of ART depends on whether it can overcome its current status as a proprietary technology with limited large-scale deployment.
