Fatal and nonfatal pedestrian crashes spanning daylight saving time were analyzed to assess the relative magnitude of risk in darkness for crash scenarios related to each of three forms of adaptive headlighting-curve lighting, motorway lighting, and cornering light. For curve lighting, pedestrian crashes on curved roadways were examined; for motorway lighting, crashes with attributes associated with motorways were examined; and for cornering light, crashes involving turning vehicles at intersections were examined. Fatal crashes were sampled from FARS 1987-2004; fatal/nonfatal crashes were sampled from the North Carolina crash dataset, 1991-1999. In the curve analysis, lower dark/light crash ratios were observed for curved sections of roadway compared to straight roads. This pattern was observed in both the fatal and nonfatal crash data. In the analysis of motorway attributes, posted speed limit was the dominant predictor of crash risk in darkness for the fatal crash dataset; road function class was the dominant predictor for the fatal/nonfatal dataset.
