8. Definitions, Acronyms and Abbreviations
This section includes a summary of the definitions, acronyms, and abbreviations used throughout the report.
8. 1 Definitions
This subsection includes definitions of the boundaries of the ICMS Corridor as well as definitions of how data is transferred between ICMS Systems.
- ICMS Freeways
- Reference to ICMS Freeways in the
SRS shall include
all of the following:
- I-394 West of I-494
- I-494 from TH 7 to TH 55
- TH 169 from TH 7 to TH 55
- TH 100 from TH 7 to TH 55
- ICMS State Operated Arterials
- Reference to ICMS State Operated
Arterials shall include all of the following:
- TH 7 from I-494 to downtown Minneapolis
- TH 55 from I-494 to downtown Minneapolis
- ICMS Local Arterials
- Reference to ICMS Local Arterials shall include non-state operated arterials road segments within the boundaries formed by TH 7, I-494, TH 55 and the City of Minneapolis.
- I-394 Mn/PASS Lanes
- Reference to I-394 Mn/PASS Lanes shall include the High Occupancy Toll lanes operated on I-394.
- The ICMS Corridor
- Reference to the ICMS Corridor shall inclusively include all road definitions within the corridor (ICMS Freeways, ICMS State Operated Arterials, ICMS Local Arterials, I-394 Mn/PASS Lanes).
- Send Data
- Send data is used to describe a data exchange where one system (System A) connects to a second system (System B) and (after handshaking) sends a message or data set. System B responds to verify if the message was received properly or not.
- Receive Data
- Receive data is the term used by a system that is waiting for other systems to send data. Using the example above, System B receives data. In order to receive data, a system must operate in a mode that is waiting all the time for other systems to connect and send data.
- Post Data
- A system posting data ‘publishes’ the data or message set in a location where other systems can come and collect the data. An XML post is a common form of data post. The data post can either be in a public location, such as the Internet; or in a secure location where only authorized systems may access it. For purposes of this ICMS, all data posts will be public posts.
- Acquire Data
- A system that acquires data follows a timed cycle to visit a location where data is posted and acquires the data. Unlike receiving data, the system must actively visit the post site and gather the data.
