Safety of motorway lighting Bruneau, Jean-Francois ; Morin, Denis ; Pouliot, Marcel
Publication details: Transportation Research Record, 2001Description: nr 1758, s. 1-5Subject(s): Bibl.nr: VTI P8167:1758Location: Abstract: The safety aspects of motorway lighting and its capacity to prevent nighttime accidents are examined. The analysis is based on a night/day accident rate ratio method to compare the safety benefits of two alternatives to dark motorways: continuous lighting and interchange lighting alone. Various sources of data are used to calculate night/day accident rate ratios, such as traffic volume records, accident databases, and field surveys. Three categories of accidents have been used: fatal and injury accidents, property damage only, and all accidents. The results are similar to those from recent literature. Continuous lighting reduces the overall accident rate by 33% (p<.001) in comparison with interchange lighting alone and by 49% (p<.05) compared with dark motorways. Furthermore, a breakdown by categories of average daily traffic for these comparisons reveals that accident reductions are still valid regardless of traffic flow.| Cover image | Item type | Current library | Home library | Collection | Shelving location | Call number | Materials specified | Vol info | URL | Copy number | Status | Notes | Date due | Barcode | Item holds | Item hold queue priority | Course reserves | |
