Background: The main index used to assess the quality of road lighting installations refers to simple detection tasks in foveal vision, which raises methodological and practical questions. Method: The experimental design consisted of a three-phase experiment. In the first phase, two groups (control and experimental) performed a peripheral detection task (simple task). Based on these results an individual detection threshold was computed for each participant and eccentricity. A tracking task was performed in Phase 2 for both groups (steering a tracking target along a circuit, on a screen). In the third phase, the control group performed the same task as in Phase 2. The experimental group performed a double task, with a tracking (primary) task and a peripheral detection (secondary) task. Results: The data show an effect of the tracking task and eccentricity on peripheral event detection. The tracking task caused detection performance to decrease from 84.2% to 67.5%, p &lt; .001. Conclusion: The small target visibility model used in road lighting may be improved, taking into account the effects of task and eccentricity on target detection. Application: This study supports improved roadway lighting design by guiding consideration of sign eccentricity and task load. <\/jats:p>","DOI":"10.1518\/001872008x312260","type":"journal-article","created":{"date-parts":[[2008,8,8]],"date-time":"2008-08-08T02:44:44Z","timestamp":1218163484000},"page":"712-721","source":"Crossref","is-referenced-by-count":17,"title":["Effect of Task and Eccentricity of the Target on Detection Thresholds in Mesopic Vision: Implications for Road Lighting"],"prefix":"10.1177","volume":"50","author":[{"given":"Ana\u00efs","family":"Mayeur","sequence":"first","affiliation":[{"name":"Laboratoire Central des Ponts et Chauss\u00e9es, Paris, France"}]},{"given":"Roland","family":"Br\u00e9mond","sequence":"additional","affiliation":[{"name":"Laboratoire Central des Ponts et Chauss\u00e9es, Paris, France,"}]},{"given":"J.M.
