Purpose of this presentation…Purpose of this presentation…
Purpose:– Informational presentation (not a design review)– Provide data flows from SunGuide to FL-ATIS– Provide insight into data being provided to FL-ATIS
Objectives:– Establish a baseline understanding of how SunGuide
will be used to “create” data for FL-ATIS
No intent:– To revisit R4.0 design decisions

Release 4.0 and FL-ATIS Release 4.0 and FL-ATIS ResponsibilitiesResponsibilities
SunGuide C2C is the “transport mechanism” If other agencies (e.g. OOCEA) wish to provide data it
MUST comply with the SunGuide C2C interface requirements

TMDD Network ModelTMDD Network Model(TMDD = Traffic Management Data Dictionary)(TMDD = Traffic Management Data Dictionary)
The network model is the underlying data model for C2C Travel times / traffic conditions are published as “link” data Each SunGuide deployment is its own network SunGuide web site (511 web site in D5) utilizes data from
multiple networks

How SunGuide Data gets to How SunGuide Data gets to FL-ATIS…FL-ATIS…
Data:– In general, as SunGuide updates data it is immediately transmitted to
the C2C– C2C pushes data to a receiver’s plugin, from there, the processing of
the data is the burden of the receiver Data Format:
– Specified in the SunGuide Center-to-Center Interface Control Document (ICD), last published on Feb 8, 2008

Providing Data to Other Providing Data to Other “Consumers” (3“Consumers” (3rdrd Parties) Parties)
C2C:
– Is the “method” SunGuide uses to transmit data outside the “domain” of a SunGuide deployment.
– Was built using the available ITS Standards produced by NEMA, AASHTO, and ITE.
The 3rd party feed identified in FDOT DFS document will be a “C2C feed”. C2C ICD:
– Has been published (this describes how to access the data).
– To access the data feed a program has to be developed that access the web service that provides data in XML format (see the C2C ICD).
– Suggestion to develop an application that simply deposits the data every ‘x’ minutes onto a FTP server has been made.
Note: the www.fl511.com developed for Release 3.0 used C2C as the source for data.

FDOT provided an Excel spreadsheet with all possible Floodgate combinations
Converted to XML file by FDOT SunGuide uses XML file which allows a “soft” configuration
– any changes to the file need to be SIMULTANEOUSLY coordinated across SG deployments and FL-ATIS

can easily performed

Scenarios / Use CasesScenarios / Use Cases(will be presented with the detailed FL-ATIS design)(will be presented with the detailed FL-ATIS design)
Goal for use cases:– Follow data from “SunGuide” to “FL-ATIS”– Allow the flow of data to be visualized through the entire
system (SG and FL-ATIS)
For each use case:– Rewritten to be consistent with SG operational paradigm– Provided with each (note each is available on SwRI’s test
server – useful for end-to-end integration testing):• Use case (stimulus)• Appropriate SunGuide GUI (this can be expanded to see
the details)• XML transmitted via C2C (as appropriate)• SAE codes and “SunGuide interpretation” (only used
within SunGuide)
