Innovative Marking Solutions: Using Colours and Symbols for Clear Communication

Colour- and symbol-based road markings have been deployed to increase safety, optimise traffic flow, and reduce operational errors across highways, car parks, warehouses, and industrial estates.

Visual cues are processed faster than text; standardised colour hierarchies are used to define zones and support regulatory compliance.

Red is specified for emergency access, fire routes, and restricted areas. Yellow is specified for caution routes, crossings, buffers, and traffic lanes. Blue is specified for disabled bays, service access, and maintenance zones. Green is specified for EV charging, waste management, and sustainability areas.

Symbols are integrated for universal recognition using ISO/ANSI pictograms, including EV, disabled access, directional arrows, and safety signage; pairing with colour fields enables immediate identification and legal conformity.

Thermoplastic has been selected for high durability, colour retention, and heavy-traffic resistance; acrylic MMA is applied where rapid curing and minimal downtime are required.

Best practice requires high contrast (≥70% luminance difference), slip-resistant textures, and load-rated finishes suitable for forklifts and HGV movements.

Measured outcomes have included fewer collisions, reduced directional errors, faster pallet location, and lower picking mistakes in distribution environments.

Specialist installation methods are utilised to ensure colour consistency, symbol accuracy, and controlled programme delivery with minimal operational disruption across South East Wales by Roman Roadmarking.
