Installation of Mobile Toilets in Subway Stations

The installation of mobile toilets in subway stations is primarily aimed at flexibly and promptly supplementing sanitation service capabilities to address key pain points for passengers during their travels.

I. Flexible Response to Demand
Mobile toilets are designed with a modular approach, essentially functioning as independent 'functional boxes' that do not require complex civil engineering construction. They can be quickly installed in designated open spaces near subway station exits or in non-core passenger flow areas of the concourse through lifting or transportation. Management can swiftly add sanitation facilities based on high passenger volumes during holidays, temporary events, or urgent needs at specific stations. For instance, when a station experiences a surge in passenger traffic due to an event, mobile toilets can be promptly deployed to the site; when the passenger flow pattern changes and they are no longer needed, they can be easily removed and the site restored to its original condition, causing minimal disruption to existing space. This effectively fills the structural gap left by fixed public toilets, whose layouts often struggle to match the spatial and temporal variations of instantaneous crowd gatherings.

II. Comprehensive Internal Composition with Emphasis on Hygiene
A standard single unit typically includes basic facilities such as a squat or sit toilet, a sink, a mirror, hooks, lighting, and an exhaust fan. High-quality models feature antibacterial material panels for easy cleaning and maintenance. Most are equipped with integrated processing systems that employ water-saving and environmentally friendly technologies, such as high-pressure water-saving flushing equipment, microbial degradation, or chemical treatment techniques, reducing water consumption and subsequent treatment burdens. Some facilities integrate automatic感应 (Note: '感应' should be translated as 'sensor-based' in context, but here it's part of the original Chinese term which might imply 'automatic sensing' functions; for clarity, we can say 'automatic sensing') flushing and handwashing functions to minimize the risk of contact transmission. Management also establishes strict cleaning and disinfection procedures, assigning dedicated personnel for frequent cleaning to ensure hygiene standards are met.

III. Humanized Design Considerations
Taking into account the diverse needs of subway passengers, some stations are equipped with multifunctional mobile toilet units that include accessible restrooms. These units have more spacious interiors and are fitted with handrails to facilitate use by individuals with mobility impairments, the elderly, or parents with young children. Ample ventilation and lighting help alleviate the sense of confinement in small spaces, enhancing the user experience. For example, at Panyu Square Subway Station, which experiences high passenger volumes and lacks nearby public toilets, Shiqiao Street installed a mobile public toilet at both Exit C and Exit D. Each toilet has four stalls, sinks and faucets outside the stalls, and sewage pipes, providing free access to citizens and effectively addressing the issue of passengers having nowhere to go when in urgent need.
