This slide is labeled Technology Architecture Summary View Example for Fixed Route Transit. Please see the Extended Text Description below.

(Extended Text Description: This slide is labeled Technology Architecture Summary View Example for Fixed Route Transit. It has four primary boxes representing, from the National ITS Architecture, Center, Field, Vehicle, and Traveler, which may be connected by Communications. Not all the details can be seen in this graphic, so four additional slides show expanded views of the four primary boxes. The large top left box is labeled Center, and it provides examples of where technology equipment such as servers and CAD/AVL consoles may reside. It shows them in sub-boxes such as Data Center, Bases, and Transit Control Center. The box in the lower left is labeled Field (not bus base) and it has two sets of nested labeled boxes. The top one is labeled ITS Cabinets and lists three examples of technology elements that might be in an ITS cabinet. The bottom box is labeled Tech Pylon/Transit Kiosk and shows an image of a Tech Pylon with a Transit Kiosk. Inside the box are labeled images of a real-time information sign, a stand-alone fare processor and a passenger information sign, plus a box labeled Mobile Access Router. The box at the lower right is labeled Vehicle and it shows or lists examples of technology elements that might be on a bus or a non-revenue vehicle. It has an outline of a bus that contains a network of 13 elements such as an image of a farebox, a fare transaction processor, and a driver display unit. The bus has a sign on the side that lists examples of Onboard ITS Functions such as Automatic Vehicle Location and Automatic Passenger Counters. The Traveler box on the upper right-hand side shows examples of technology devices that a traveler might have. The Traveler box shows images of a fare card, mobile/smart phone, telephone and a PC/laptop. Possible examples of Communications between the Center, Field and Bus are represented by "cloud" bubbles for a Transit WAN, Regional ITS Network and a Transit ITS Network, and by graphical lightning bolts representing wireless communications between elements. For example, a lightning bolt connects an image of radio towers that represents transit radio sites to the Mobile Radio box in the bus outline. Each transit agency might develop a Technology Summary View diagram that represents the elements used at their agency and how they are connected at a high level. The contents of the four primary boxes are discussed further in the next four slides.)

Review of Answers

A small graphical red and yellow X representing incorrect.a) Be focused on creating business results
Incorrect. A business results focus supports efficiencies.

A small graphical green and yellow check mark representing correct.b) Buy the most advanced, complex software
Correct! For example, the most advanced software application may create inefficiencies because it's difficult to use and maintain.

A small graphical red and yellow X representing incorrect.c) Control technical diversity
Incorrect. Controlling technical diversity, such as through the use of standards, creates efficiencies.

A small graphical red and yellow X representing incorrect.d) Have an enterprise-wide perspective
Incorrect. An enterprise-wide perspective promotes efficiencies, as it helps find redundancies and other issues.
