What is a key characteristic of articulated buses?

Articulated buses are designed with a flexible joint that allows them to bend in the middle, which significantly increases their passenger capacity compared to standard buses. This design enables them to transport more passengers, making them ideal for high-density urban areas where the demand for public transportation is greater. The increased length and the ability to accommodate a larger number of seats or standing room provide an effective solution for mass transit needs.

In contrast, while articulated buses have advantages in passenger capacity, they may not be the best choice for navigating narrow streets due to their longer size and the need for more extensive turning radii. Additionally, articulated buses generally utilize traditional diesel engines or hybrid systems rather than having a distinctly different engine type. Lastly, they do not have a single rigid frame; instead, they are composed of two connected sections which allow for flexibility.
