Detailed Description:
 
Variable Message signs are short for VMS. The phrase “VMS” is referred to exclusively throughout the contents of this document. However, other commonly used terms describing highway signs that can display different messages are found within National and New York State publication and policy documents. Examples of these terms are as follows: 
1. “VMS” (Variable Message Sign) shall mean a device to display a variety of text messages to motorists traveling the Thruway.  It is a traffic control device that typically suggests motorists alter their driving in some manner and take appropriate actions. A VMS is not typically used as a regulatory sign as recognized within the MUTCD Manual on Uniform Traffic Control Devices). 
2. “CMS” (Changeable Message Sign) shall mean a non-static sign that supports a limited number of fixed messages. An example would be the rotating drum sign used in E-Z Pass operations. This term is currently contained in the 2003 edition of the Federal MUTCD (Manual on Uniform Traffic Control Devices).  
3. “CEVMS” (Changeable Electronic Variable Message Sign) shall mean a changeable message sign of a digital / LED-LCD display type that conforms to Federal and State statutes.   
4. “DMS” (Dynamic Message Sign) shall mean a changeable message sign as part of the NTCIP (National Transportation Communication for ITS Protocol).  
5. “BOARDS” shall mean changeable message signs as used in the Authority’s Traffic Safety.
 
Warm Tips:
 
   When using texts, care should be taken that the text can be read at a sufficient distance. One rule of thumb is that the minimum reading distance (in meters) is about 5 to 6 times the letter height (in cm). For example: a 36-cm high letter can be read at a distance of about 200 m from the sign. 
   When planning to install new VMS, authorities should know that the European VMS standard (EN 12966) is obligatory for all fixed VMS signs used in traffic applications. This is not yet the case for temporary or mobile VMS because the Construction Products Directive (CPD) is only valid for products that are in permanent use. An informative appendix of the European VMS standard (EN 12966) provides guidance in choosing the correct combination of the various items mentioned above.
 
VMS’s Popular Application:
 
Generally speaking, VMS is used to communicate in real-time with motorists. VMS messages must address current conditions on the roadway by being dynamic, accurate, timely and understandable. When there are multiple requests to post VMS messages simultaneously, messages will be prioritized in the following order of importance: 
1. Incident Management / Public Safety;
2. Congestion Management / Motorist Guidance;
3. Construction / Maintenance Activity;
4. Special Events;
5. Environmental;
6. Law Enforcement Message;
7. Public Service Campaign.
