Abstract
The work starts with a brief overview of the main issues concerning road lighting control systems, e.g. the visual conditions in night time driving, the light sources used in road lighting, and the basic structure of telemanagement lighting control systems. Then the work focuses on the performance of intelligent road lighting control systems by using the examples of two installations in Finland, Ring III and VT7. The real benefits and drawbacks are discussed and financial calculations are given. The work continues with the subject of road surface luminance measurements in order to suggest ways in which the performance of intelligent road lighting control systems might be optimized. This subject is topical as there are currently several practical problems in luminance monitoring. The work also investigates the main control parameters and strategies that are applied currently and tries to find the basis of dynamically changing light levels.Description
