WMATA Real-Time Parking Information Feasibility Study Summary Chapter 3: BEST PRACTICES REVIEW o Linking permits and fare collection so that permits could be entered or scanned and then fare collection data queried to ensure these patrons entered the system, o Heat signature and image recognition systems to ensure compliance. While various combinations of APS technologies have been deployed at airports, transit agencies, and urban areas, each individual system has been tailored to local needs to provide motorists with the information they need to make informed parking and mode choice decisions. In most cases, research and feasibility studies were completed to ensure that the systems deployed accomplished stakeholder goals. As a result of initial needs assessments and follow up studies, many jurisdictions have been able to compile lessons learned related to the system of their choice. For systems with multiple stakeholders, it has been noted that agreements dictating the responsibilities between each involved entity should in all cases be finalized before construction of the system begins. This will alleviate potential issues arising from operational concerns and also allow for problems to be addressed more efficiently if or when they occur. Additional lessons learned include pre-testing of the vehicle sensors whether they are individual space sensors or entry/exit counters. Pre-testing allows for the de-bugging of any potential issues before the system is made available to the public decreasing the likelihood of a negative public reaction. Public outreach as to how to use the new technologies and/or facilities was also cited. The majority of jurisdictions plan continued or expanded use of their current systems based on positive user reactions, increased revenue at some locations, and increased use of transit services.

WMATA Real-Time Parking Information Feasibility Study Chapter 4 REAL-TIME PARKING TECHNOLOGY This chapter addresses the functional requirements needed for a real-time parking information system. It identifies the goals and objectives of the system as determined through interviews with WMATA and Virginia Department of Transportation staff. This is followed by a review of available technology. A real-time parking information system is comprised of a variety of elements that generate raw data, process the data into useable information, and transmit the information to users. Each of these elements can be addressed with a number of different technology options. The system vision includes seamless communication of available parking information from the detection of parking occupancy to public notification. To analyze technologies considered for system deployment effectively, they must be evaluated with respect to the needs of the system. To accomplish this, the goals and objectives of the system must first be determined. This document reviews the goals and objectives and identifies the functional requirements needed to achieve them. Different technologies are reviewed to understand their potential for meeting the functional requirements. Goals, Objectives and Functional Requirements Goals are defined as high level statements of a result that, when accomplished, will achieve all or part of the vision. Objectives are defined as a set of statements that include specific measurable accomplishments directly related to the opportunity, need, or problem addressed by a goal. Once goals and objectives are established, functional requirements are determined in order to provide implementable and verifiable requirements that define how to meet the objectives. It should be noted that functional requirements define how the system should function and do not specify the technology used to meet the requirements. Goals and objectives were established for this project based on the desires of WMATA and VDOT using information from interviews conducted in May 2008. The goals and objectives address matters such as operation of parking facilities, customer satisfaction, parking payment processing, and information sharing between agencies. The long-term goals, objectives, and functional requirements for this project are shown in Table 4-1. Chapter 3 provided information on smart parking technologies. This chapter provides a more detailed discussion of the types of technologies used in different locations and which technologies are used to produce and convey different types of information. The findings detailed in this chapter will then be used to identify which technologies will meet the specific WMATA needs. The technologies are described in terms of the three basic system components: vehicle detection, data communication, and traveler information communication. Page 4-1 June 2009
