technology to achieve interoperability with peer transit systems, and interoperability between systems provided by different vendors. WP4 focuses primarily on producing standards and guidelines to achieve the following objectives: • Interoperability between a single transit system’s fare payment devices, and a central system as illustrated in Exhibit 1.1-1. • Interoperability (possibly limited) between two regional central systems as illustrated in 1.1-2 These objectives support APTA’s goal of increasing interoperability among smart card based transit systems in the U.S. This will benefit all transit systems by increasing competition among vendors when expanding or upgrading their systems and facilitating a staged regional rollout approach. The typical regional payment system has four tiers of devices and computer systems: • Regional Central System – Consolidates and processes transactions and establishes settlement positions between agencies • Headquarters Computer/Operator Central Tier – Utilized by participating agencies to collect transactions for internal auditing and reporting and/or control agency specific functionality. This tier is optional, as some agencies pass data straight from the station/depot computer tier to the central system. In addition, some systems will include an “audit computer” to audit the data in the central system instead of a headquarter computer system. • Station/Depot Computer Tier – Deployed in stations or bus depots to collect usage data from fare payment devices and download configuration data to devices from the Headquarters Computer/Operator Central Tier. This tier is optional, as some agencies have opted to pass data straight from the Device Tier to the Headquarters Computer/Operator Central Tier. • Device Tier – Deployed on vehicles or at stations and other points where the patron’s card interfaces with the system The system tiers and related interfaces explained in this section are illustrated in Exhibits 1.1-1 and 1.1-2.

1.0 INTRODUCTION<br />

A growing trend in North America and abroad is a move towards regional fare<br />

payment systems. Regional programs involve multiple transit systems linked by a<br />

<strong>com</strong>mon fare payment instrument, most <strong>com</strong>monly a smart card. Open standards and<br />

interoperability between different vendor equipment within an electronic fare payment<br />

system have be<strong>com</strong>e highly desirable, and in some instances, necessary.<br />

Interoperability is defined in this report as follows:<br />

1. The ability <strong>of</strong> fare payment devices to exchange data with other vendor devices<br />

within a single fare collection payment system<br />

2. The ability for independently implemented multiple fare payment systems to be<br />

operable with each other regardless <strong>of</strong> the underlying technology <strong>of</strong> the each<br />

system<br />

Transit agencies deploying smart card technology have very few industry standards to<br />

facilitate interoperability and reduce their reliance on proprietary technology. Agencies<br />

locked into proprietary technology have fewer procurement options and limited ability<br />

to participate in regional systems. Moving forward, individual transit agency devices<br />

and <strong>com</strong>puter systems must be interoperable, and preferably based on open standards.<br />

Today, transit agencies participating in regional programs, absent <strong>of</strong> industry wide<br />

standards, have encountered difficulties such as the following:<br />

• New systems<br />

- Increased coordination required between participating agencies before<br />

equipment procurements<br />

- No independent source to <strong>com</strong>pare different proprietary approaches<br />

between <strong>com</strong>peting vendors<br />

- Less <strong>com</strong>petitive initial marketplace<br />

• Existing systems<br />

- Post implementation equipment options are constrained<br />

- Reduced ability to collaborate with non-transit industry partners due to<br />

proprietary interfaces<br />

- Few options for replacing non-performing vendors in mid-stream<br />

1.1 Objectives<br />

1.1.1 APTA Objective<br />

The American Public Transportation Association (APTA) standards activity, through<br />

the work <strong>of</strong> the Universal Transit Farecard Standards (UTFS) Program, defines interface<br />

standards and best practices for use at transit systems throughout the United States that<br />

provide uniform guidelines for system interoperability. The program aims to produce<br />

standards and re<strong>com</strong>mended practices to help transit systems deploying smart card<br />
