Transport for London – PRODUCT DESIGN GUIDELINES 2009

Description

Transport for London’s Product Design Guidelines define criteria for any manufactured object used in TfL public environments (signage, furniture, gateline equipment, fittings, security and revenue products). Successful design requires balancing three priorities: aesthetics, appropriateness and economics, expressed through 24 approval criteria. Aesthetics demand a consistent, robust design language (precise engineering with softened forms), controlled detailing, suitable materials and finishes, ergonomic and inclusive design (DDA compliance), appropriate colour contrast, sensitivity to heritage sites, and cautious commercial branding. Appropriateness covers installation, secure fixings, easy removal and disposal, clear sight lines, security (no hiding places), intuitive operation with feedback, cleanability, and vandal-resistant durability. Economic criteria address ownership of intellectual property and tooling, material compatibility, site context and compactness, flexible mounting, minimal onsite work, use of standard parts, spare-part availability, front access for maintenance, and cost/added-value trade-offs.
