Accidents on rural roads: dual carriageway 'A' class roads

01 October 2007

This second report on 'A' class rural roads focused on the subject of traffic accidents on two lane dual carriageways in Cambridgeshire. Eight lengths of dual carriageway were selected for examination on the basis of their design standard, design speed and traffic flows. The data available for the study consisted of eight years' STATS19 report data (1988 to 1995), road environment information (inclusive of maintenance and speed data), and a driver questionnaire. Ten databases were generated around the above information, and interactions between the data were explored using statistical models.
