| Abstract | A large number of bridges on two-lane rural highways are narrow bridges. While there is no universally accepted definition of this type of bridge, it is generally considered to be one where the roadway and/or shoulders narrow significantly. It has been recognized that this situation produces accidents with either the bridge structure, oncoming vehicles or both. In this volume, an experimental design was developed to measure the relative effectiveness of various types of active and passive devices to warn motorists of the presence of a narrow bridge ahead. Suggested measures of effectiveness and the necessary statistical tests are described. In addition, a state-of-the art survey and bibliography are presented. |
