Crash risks while driving at night are higher than during the daytime, but most roadways in the U.S. do not have roadway lighting. In fact, many state and local governments find it difficult to pay for installing, operating and maintaining roadway lighting. Despite these concerns, the proportion of nighttime driving is not likely to go down in today's round-the-clock economy, making car headlights increasingly important to nighttime driving safety. Through its Transportation Lighting and Safety program, the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute is evaluating the potential for new lighting technologies and approaches to improve driving safety at night, including new car headlight systems.
