Roads in the conventional residential areas serve the purpose of leading to and from the houses in them. Thus, they are essentially traffic routes which may carry all road traffic modes, viz: pedestrians, pedal and motor bicycles, motor cars and trucks, and public service vehicles (buses or trams). Furthermore, it should be realised that in many cases the residential area either contains or at least borders on areas with social functions, areas that often create or attract much traffic (hospitals, shopping centres, sport facilities, offices and even factories). Thus, roads in residential areas always have a traffic function, and often an important one. The requirements for this traffic function must be met both at day and at night. As a consequence, residential areas have nearly always a "public" lighting installation which may have further functions for public safety. Additionally, all vehicles carry lights that illuminate their way apart from signalling lights. This paper deals with aspects of public and vehicle lighting and their interactions. The paper was presented to the Chartered Institution of Building Services CIBS annual conference 1979, Harrogate, 19-23 May 1979.
