| 摘要： | Portable changeable message signs (PCMSs) have become an integral part of work zone traffic control in Texas, advising motorists of unexpected traffic and routing situations. When used properly, these signs can command additional attention over that achievable through regular static work zone signing. Furthermore, PCMSs can present a wide variety of information to motorists, making them a highly versatile tool to traffic control designers and to work crews. PCMS have been used in a variety of applications in both construction and maintenance work zones. Some of these applications are to: (1) warn of a new detour or of a change in a detour, (2) warn of a ramp closure, (3) identify the presence of a lane drop where a continuous lane once existed, (4) emphasize the existence of reduced speed limits within a work zone, (5) warn of downstream traffic queues (especially due to lane closures), (6) warn of the presence of downstream flaggers or work crews, (7) notify motorists to turn to a highway advisory radio (HAR) station for more details, and (8) alert motorists of future changes which will be made to current traffic conditions. |
