Procedure for continued urban lighting management evaluation

Abstract

In order to evaluate the urban lighting management, a procedure based on the benefit/cost operation relationship is described. Taking into account several types of facilities under different management and maintenance policies, field surveys were carried out in Order to correlate cost and benefits. The collected data as well as historical data provided by lighting maintenance companies were analyzed to formulate and test the proposed procedure. A quantification of the benefit based on such Factors as the lighting level, the permanent failure rate, the lighting system operating time, etc. is proposed. The management planning based on a simple procedure allows the implementation of a maintenance policy which can be subsequently adjusted with control data. Finally the results achieved on existing installations are described.
