摘要:This article tries to survey and criticize the quality of lighting and illumination in the central district of Tehran, by comparing it to standard codes. Findings report that the traffic lighting is standard, but illumination of sidewalks and pedestrian areas and cycle paths has many problems. Most of the important buildings of the district are not illuminated properly and lighting them according to their masses and architectural features is needed. In conclusion it has been resulted that there is a distinct need to a master plan for public lighting which, apart from defining general concepts, often put forward designs for specific urban districts and unifies light design in them.
