Abstract
In recognition of the fact that at intersections the driver frequently needs better than ordinary visibility of the driving environment, the Texas Highway Department in 1957 authorized TTI to undertake a research project to investigate the effects of various types of intersectional illumination and signing on traffic safety and performance. This article presents only partial findings to date. It includes the experiences with the methods of investigation, discusses some problems encountered, and gives significant findings generally indicative of the type of results being obtained.|The researchers believe that the studies generally have shown that:| 1. Intersectional illumination, signing, and designing must be as closely co-ordinated as possible at the design stage.|2. No single standard illumination design is adequate for the variety of geometric and environmental conditions encountered at intersections.|A final report on significant results will be completed in 1962.
