| 摘要： | Intelligent Transportation systems (ITS) are being implemented in metropolitan areas across the Untied States as a tool for managing congestion. As these systems grow and attain acceptance, transportation officials and motorists alike begin looking for these technologies during other times of congestion. Events like work zones, incidents and evacuations often cause excessive delays and backups. While these areas have times of critical need, the normal traffic volumes generally do not justify the expense of permanent ITS technologies. One of the most popular and recognizable elements of ITS is closed circuit television (CCTC) cameras. These cameras provide real-time video to transportation officials managing traffic during peak hours and at incident scenes. The images returned to a traffic management center (TMC) are used to determine the additional information and guidance required by motorists, the progress of removing the cause of congestion, as well as personnel and equipment needs in the field. Installing video technology in areas with seasonal traffic volumes may not be economically feasible, but having this tool during peak times offers many benefits to motorists. Using portable camera systems, in conjunction with portable changeable message signs (CMSs) and highway advisory radios (HARs) aids in providing motorists with incident information and route alternatives need to make informed traveling decisions. The expansion of ITS in these areas has the potential to reduce congestion and driver frustration. These systems also can be sued to demonstrate the capabilities of ITS for traffic management and help assess the benefits of permanent installations. |
