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

"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 Shelley Row the 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 you.

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 for participating and we hope you find this module helpful."

Exercise #3 - User Needs

When would this user need be required (for the agency)?

The operator needs to be able to define and edit the appearance of the fonts used to display messages on the sign face.

Hint: Consider the type of sign!

A picture showing a portable dynamic message sign, displaying the words, Workmen Ahead Slow Down.

 

Slide 40:

Exercise #3 - User Needs

2.5.1.3 Manage Fonts

This feature allows the operator to define and edit the appearance of the fonts used to display messages on the sign face. This helps an operator ensure that messages have a consistent appearance across many DMS in a large system despite the use of different manufacturers, etc. It allows the operator to manage the height and width of the font and the color of the font. It allows the operator to edit or delete existing fonts, and to create new fonts in a controller. It also allows an operator to determine the existing configuration of fonts.

Each font supported by the DMS should support a common set of characters (e.g., ASCII codes) to improve interoperability, including letters numbers and various special characters that are frequently used on DMS

When might this user need not be needed (for the agency)?

2.5.1.2 Determine Sign Display Capabilities

This feature allows the operator to retrieve the necessary information to produce a rendering of a suggested or active message. This feature also allows the system to ensure that a message can be displayed on the DMS. The feature allows the operator to determine the detailed physical limitations of the DMS as well as details regarding the current fonts and any graphics that are stored.
