The Development of On-Premise Electronic Message Center Lighting Levels and Sign Lighting Measurement Techniques, Phase 2

Research conducted recently for the United States Sign Council Foundation (USSCF) found that there is no consensus on lighting measurement or appropriate lighting levels of on-premise Electronic Message Centers (EMCs). This is the second phase of a two-phase study to remedy this situation. In Phase 1, standard EMC light level testing procedures are being established and EMC lighting levels that optimize sign legibility at night from the prospective of a motorist who is viewing the EMC are being developed. Phase 2 will result in EMC lighting levels that optimize sign legibility during daylight. The proposal consists of two tasks. Task 1 uses The Larson Institute's test track to conduct original human factors research with the goal of optimizing daytime EMC lighting levels based on sign legibility. Task 2 is the development of a Final Report that will include standards for daytime EMC light levels based on the results of Task 1.
