| 摘要： | The DMS NTCIP working group is drafting Version 2 of NTCIP 1203 Object Definitions for Dynamic Message Signs. Version 2 represents a major upgrade in the functionality of the DMS standard. Version 2 is scheduled to be distributed for user comment during the spring of 2003. DMS working group members will assess user comments and determine if any further work is required on the standard. NTCIP 1203 allows integration of DMS devices and products from multiple manufacturers into a single system using standard communications and data. Version 2 adds features such as graphics and device status reports. This version also restructures the standard to make it easier for end users to specify product attributes and/or capabilities. Added detail in Version 2 enables all parties, including users, designers vendors and integrators to build systems that meet requirements identified through the systems engineering process. Rigorously identifying requirements will enable the public agency to construct robust compliance tests for vendor systems to meet. |
