This report presents and reviews common linear and spatial location referencing systems used by road authorities and discusses the various benefits and limitations of each. Road authorities have traditionally used linear location referencing to define and locate their assets. However each road authority typically has its own unique combination of location referencing methods and systems, evolved and tailored to cater for the unique characteristics of their respective road network and business needs. The variance between location referencing systems and a lack of detailed common ground limits data transfer between member authorities and aggregation of higher order comparative databases (i.e. at the national level). It also creates extra work in planning and conducting data collection surveys, in that new data collection systems must be developed for each new data collection exercise to suit each location referencing regime.
