The new IHI APM (Automated People Mover) system integrates numerous advancements in passenger convenience and comfort. Through detailed numerical analysis and data acquisition procedures performed on a dedicated IHI test track, passenger ride quality advancements now set a new market benchmark for rubber tired technology. Similarly, the HVAC subsystem integrates new 'smart' system features designed to optimize passenger comfort and reduce energy consumption. Information systems and a spacious interior cabin embody similar advancements. This paper explores these features in detail including the implications for future applications. IHI implemented several improvements to enhance ride quality. IHI achieved improved ride quality in the vertical direction at a higher maximum speed than the Yurikamome baseline system (standard for APM vehicles in Japan) by reducing the irregularity of the running surface and adding carbody reinforcement. Also IHI achieved improved ride quality in the horizontal direction by adjusting the guide rail flatness. The new IHI APM now exhibits excellent ride quality at a higher speed than most conventional rubber tired APM vehicles. The ultimate effect is to allow improvements in system transportation capacity and headway. The IHI HVAC system features a new up-flow concept installed under the APM vehicle frame. IHI has measured and evaluated several important criteria for this concept, resulting in improved flow patterns, reduced noise levels, and uniform temperature distribution in the cabin. The merits of installing HVAC units under the frame include the following: 1. Noise reduction vs. a ceiling-type unit. 2. Improved maintenance vs. a ceiling-type unit. 3. Reduced weight of carbody from eliminating structural needs of ceiling-type units. To achieve a wide screen LCD panel design for passenger information systems, featuring a larger graphical image for advanced advertising impact, IHI improved the LCD screen visibility during normal daytime operations.
