摘要：	The overall goal of the Federal Highway Administrations (FHWA) Visibility Research Program is to enhance the safety of road users through near-term improvements of the visibility on and along the roadway. The program also promotes the advancement of new practices and technologies to improve visibility on a cost-effective basis. The following document provides a characterization of vision enhancement systems used in the evaluation of the performance of drivers during nighttime driving in the Enhanced Night Visibility (ENV) project. These systems include halogen and high-intensity discharge headlamps, UVA emitters used to augment the headlamps, and in-vehicle sensors for nearinfrared emitters and far-infrared detectors. The ENV project provides a comprehensive evaluation of evolving and proposed headlamp technologies. The individual studies within the overall project are documented in an 18-volume series of FHWA reports, of which this is Volume XVII. It is anticipated that the reader will select those volumes that provide information of specific interest. This report will be of interest to headlamp designers, automobile manufacturers and consumers, third-party headlamp manufacturers, human factors engineers, and people involved in headlamp and roadway specifications. / NOTE: Final rept. / Supplementary Notes: Sponsored by Federal Highway Administration, McLean, VA.
