One of the objectives of a local government body could be 'to provide adequate street lighting throughout the area'.
(a) How could the 'adequacy' of street lighting be measured?
(b) Assume that other objectives are to improve road safety in the area and to reduce crime. How much does 'adequate' street lighting contribute to each of these aims?
(c) What is an excessive amount of money to pay for adequately lit streets, improved road safety and reduced crime? How much is too little?
