signalétique

Signalétique is the field of designing, implementing, and maintaining signs and related graphic systems that convey information, provide directions, and support safety in built environments. It encompasses portable and fixed signs, wayfinding maps, information panels, pictograms, floor and tactile markings, and branding elements integrated with architecture and urban space. The aim is clarity, legibility, and rapid recognition across different lighting, distances, and languages.

Key design considerations include legibility (typography, size, contrast), information hierarchy, color coding, and consistent iconography. Accessibility is central, with attention to visual impairment, multilingual audiences, and the inclusion of tactile or braille options. The system should be understandable at a glance while complying with local regulations and cultural context.

Practically, signalétique is multidisciplinary, combining graphic design, architecture, urban planning, and information science. A signage program typically starts with goals, user research, and site analysis, then defines graphic standards and production specifications. Regular maintenance keeps signs readable and information current.

Standards exist at international and national levels. ISO 7010 governs safety signs and symbols; many countries maintain additional standards for typography, color, and layout. In recent years, signalétique has expanded to digital displays and dynamic wayfinding that interact with mobile devices and real-time information systems.

Applications include transportation hubs, hospitals, schools, offices, campuses, public squares, and retail environments. Overall, signalétique balances function, aesthetics, and branding to help people navigate spaces efficiently and safely.
