This manual is intended to help the local engineer understand the basics of good roadway lighting and achieve some of its benefits; it is not addressed to the professional lighting engineer or consultant. It cannot give definitive ‘best buys’ for the enormous range of conditions and situations which the engineer has to face. Instead, it sets out the various options, and their strengths and weaknesses, so that engineers can make the most of their scarce budget and equipment. Although road lighting is only one of the many services provided by engineers, it is one that can make a positive and highly visible contribution to the community’s welfare. Its effects are seen and appreciated immediately by drivers and pedestrians alike, and in the longer term there are measurable improvements in road safety and general security. It is hoped that this manual will help in this worthwhile process.
