The National Roads Authority (NRA) was formally established as an independent statutory body under the Roads Act, 1993 with effect from 1st of January, 1994. The Authority's primary function, under the Roads Act 1993, is 'to secure the provision of a safe and efficient network of national roads'. For this purpose, it has overall responsibility for planning and supervision of construction and maintenance works on these roads. The NRA Road Safety Section is charged with a number of tasks under the last Government Road Safety Strategy. Two of these tasks are to have a yearly programme of road safety remedial schemes on national roads and to carrying out a review of these road safety remedial schemes. Since 1994 the Authority has operated a programme whereby, for limited financial outlay, deficiencies at high risk collision locations can be identified and remedied. The works concerned are intended to enhance the safety of the roads system through changes in road layout, junction control and improvements in signage and road markings. The results of Programme 1 (RS 456) & Programme 2 (RS465) are available on the NRA website. This report analyses the Before & After results for Programmes 3 to 8. It also lists the schemes undertaken in Programmes 9 and 10, as sufficient time has not yet elapsed to analyse fully these schemes. It outlines the road safety remedial schemes that have been undertaken in Ireland on National Roads since 1998. It lists the schemes undertaken each year and summarises the performance of the road safety remedial schemes completed up to 2005. The report also provides an overview of the effectiveness of the different types of schemes up to 2002 with a view to ensuring future programs deliver value for money. The collision data is not yet available for subsequent years. The report measures the effectiveness of the programmes based on collision data for a 5 year before period and a 3 to 5 year after period. (Author/publisher)
