ON PREMISE SIGN RESEARCH
BRINGING SCIENCE TO SIGN REGULATION
USSC Foundation Guideline Standards for On-Premise Signs
First published in 2003 and newly revised for 2015, the USSCF Sign Standards is the benchmark for determining Sign Area, Letter Legibility, Sign Height, Parallel Sign Area and Sign lighting levels at night based on empirical research. Included are recommendations on sign brightness and Electronic Sign operation. The Standards have been included in the past two editions of the American Planning Association's Street Graphics and the Law, and the research served as the basis for many provisions in the International Zoning Code.
On-Premise Sign Lighting
On-premise Sign research related to signs and lighting. Four (4) studies completed at the Larson Transportation Institute at Penn State, covering topics such as:
- does on-premise sign lighting impact the environment in any measurable way?
- what type of sign lighting performs best for drivers at night - internal or external?
- what is the best lighting level for driver performance at night?
- in the Real World, what type of sign lighting (internal or external) is best for the needs of the motorist and traffic safety?
Parallel Sign Legibility
A 2006 USSC Foundation study on the special challenges presented by "parallel" signs, or signs typically mounted on buildings, parallel to the driver's line of sight and the roadway - wall signs.
