(Note: There is additional text attached to this slide that includes the following introductory information from Ken Leonard):

"ITS Standards can make your life easier. Your procurements will go more smoothly and you’ll encourage competition, but only if you know how to write them into your specifications and test them. This module is one in a series that covers practical applications for acquiring and testing standards-based ITS systems.

I am Ken Leonard, director of the ITS Joint Program Office for USDOT and I want to welcome you to our newly redesigned ITS standards training program of which this module is a part. We are pleased to be working with our partner, the Institute of Transportation Engineers, to deliver this new approach to training that combines web based modules with instructor interaction to bring the latest in ITS learning to busy professionals like yourself.

This combined approach allows interested professionals to schedule training at your convenience, without the need to travel. After you complete this training, we hope that you will tell colleagues and customers about the latest ITS standards and encourage them to take advantage of the archived version of the webinars.

ITS Standards training is one of the first offerings of our updated Professional Capacity Training Program. Through the PCB program we prepare professionals to adopt proven and emerging ITS technologies that will make surface transportation safer, smarter and greener which improves livability for us all. You can find information on additional modules and training programs on our web site www.pcb.its.dot.gov

Please help us make even more improvements to our training modules through the evaluation process. We look forward to hearing your comments. Thank you again for participating and we hope you find this module helpful."

(CCTV) System

(CCTV) System. Please see the Extended Text Description below.

(Extended Text Description: The slide shows an outside rectangular line boundary that surrounds two photos; a TMC photo on the left corner and a camera photo on the right corner. Both photos are then interconnected with a red rectangular line that passes through photos to show a close circuit. This diagram conveys that a CCTV closed circuit is thus formed between a camera and a TMC and images can be seen only by those within the circuit. [The purpose is to differentiate how a CCTV circuit is different than a commercial broadcasting video image that can be seen by anyone with a receiver]. )

Slide 58:

Learning Objective #3

Identifying User Needs Locations on "V" Model

Identifying User Needs Locations on V Model. Please see the Extended Text Description below.

(Extended Text Description: Text is given explains first V diagram and then the relevance of current slide. Explanation of V Diagram - A graphic of the systems engineering process (SEP) is shown. The main graphic of the SEP is a V-shaped diagram with some additional horizontal “wings” on the left and right side of the top of the V. Starting from the left “wing” the steps are regional architecture, needs assessment, concept selection, project planning, and systems engineering management planning. At this point the steps begin to descend the left side of the V with concept of operations, system requirements, high-level design, detailed design, and software hardware and field installation. At this point the steps begin to ascend the right side of the V with unit device testing, subsystem verification, system verification and deployment, system validation, and operations and maintenance. At this point the steps are on the right “wing” of the V with changes and upgrades and retirement/replacement. The following arrows supplement the figure: 1. A time line at the bottom of the figure indicating that all steps proceed over time with the steps forming the V overlapping one another. 2. A downward arrow on the left side of the V that indicates that these steps deal with decomposition and definition. 3. An upward arrow on the right side of the V that indicates that these steps deal with integration. 4. A horizontal arrow near the bottom of the center of the V that connects the detailed design step to the unit testing step. 5. A horizontal arrow a little higher that connects the subsystem requirements step with the subsystem verification step. 6. A horizontal arrow a little higher that connects the system requirements step with the system verification step. 7. A horizontal arrow near the top of the V that connects the concept of operations step with the system validation step. Finally, major steps are separated by a barrier that is labeled “document approval.” The above described graphical view of SEP life cycle process used to show where user needs are located. In this slide, at the top of the Vee, there are three boxes in yellow. The first box is Multiple Stakeholders Needs Assessed and points to Regional Architecture on Vee. Second box marked as Operational Problem Solving and Agreement points to Concept of operations on the Vee, and last one is marked as Reassessment Gaps-New Needs and points to Operations and Maintenance which is on the right top of Vee. A red circle covers ConOps (user needs) and System Validation.)

A small graphical red and yellow X representing incorrect.b) Regional ITS Architecture
Incorrect, because architecture is a framework-only partial source.

 

A small graphical red and yellow X representing incorrect.c) Standard Documentation
Incorrect, because standard offers ONLY design solutions, but not sufficient from users' perspective.

 

A small graphical green and yellow check mark representing correct.d) All of the above sources
Correct, because all of the above sources have links to user needs and assessment of each will ensure our purpose to identify user needs.

Slide 77:

Learning Objective #3

Review of answers

A small graphical red and yellow X representing incorrect.a) The TMC operator has a need for 64 presets.
Incorrect, because 64 presets is a specific requirement-a solution.

 

A small graphical red and yellow X representing incorrect.b) The CCTV system must allow for 0-360 degree Panning.
Incorrect, because it contains a specific range of solution and lacks rationale.

 

A small graphical red and yellow X representing incorrect.c) The CCTV system must provide for up to 100 labels.
Incorrect, because it contains a specific range of solution-a requirement.

 

A small graphical green and yellow check mark representing correct.d) The TMC operator has a need for monitoring current value of the temperature in the camera enclosure for proper operation
Correct, because it contains MDC, has a rationale and it is solution free.

Incorrect, all mandatory CGs are required to be conformant.

 

A small graphical red and yellow X representing incorrect.c) Extended Functions Conformance Group allows for On-Off of devices remotely
Incorrect, because this CG does support On-Off control.

 

A small graphical red and yellow X representing incorrect.d) Supports Pan-Tilt-Zoom (PTZ) remote control operation.
Incorrect, standard does support PTZ capability.

 

Slide 91:

Summary of Learning Objective #4

Evaluate Conformance to the CCTV standard

 

Slide 92:

What We Have Learned

  1. CCTV Standard does not provide user needs and user must identify and write them for project specification.
  2. User need is the first step towards achieving interoperability and vendor-independence.
  3. User needs can be found in the traffic management Concept of Operations .

 

Slide 93:

What We Have Learned (cont.)

  1. a user need must be uniquely identifiable defines a major desired capability captures a rationale and must be solution-free,
  2. NTCIP 1205 standard offers conformance groups which are defined as a grouping of the related objects.
  3. NTCIP 1205 CCTV MIB provides Objects for CCTV system design.
