Hitachi Monorail System has less environment friendly due to its simple, narrow guideway than the wide bridge structure required by other transit systems:
- The narrow guideway allows sunlight through to the surface street and surrounding residential/commercial area.
- Airflow is not blocked to/from the surface street, not causing air pollution under the structure by exhaust gas of cars.
- The narrow guideway feels less constrained for the public along the corridor.
