摘要：	Despite the emergence of various technologies and products for Advanced Traveler Information Systems (ATIS), variable message sign (VMS) remains the most popular ATIS components for real-time display of traffic conditions to en route drivers. Through properly designed messages, operators for traffic control can inform motorists about the traffic speed, delay, or queue length under either recurrent or non-recurrent congestion. Traffic control centers may use VMS to provide detour suggestions or instructions to drivers during severe congestion. VMS may also be used to direct motorists to tune into Highway Advisory Radio (HAR) for additional traffic information or incident reports. The effectiveness of VMS with respect to mitigating congestion and increasing safety, however, depends on a variety of factors, including: credibility and timeliness of displayed messages, the location of VMS, preference of driving populations, and proper integration between VMS and traffic control strategies such as ramp metering and detour operations.
