182 Ground Access to Major Airports by Public Transportation SOURCE: Portland International Airport website. Figure 9-3. When the user specifies the destination, the Portland International Airport system provides the list of carriers. Metro Area" on the opening ground transportation page produces a screen with a wide variety of very specific destinations in the Portland Metro area: examples include The Rose Gardens in Washington Park, Powell's Bookstore, and the Amtrak Depot, as well as more traditional listings of towns and cites. The choice of "Washington" produces a list of about 28 candidate des- tinations within the state of Washington. When the user finds the desired destination, clicking on the link produces the list of companies that serve that destination (Figure 9-3). Passenger Information Provided by Other Agencies The opening page for ground transportation services on the Portland International Airport website has a large icon on the upper right that offers a direct transfer to Tri-Met, the local pub- lic transportation operator. Importantly, the link is made to a page providing information about the specific line that serves the airport, rather than linking to a more general-purpose agency home page. At the light rail page, origin-to-destination trip itinerary planning is on the next level of services offered. At the data input page, the "origin" (Portland International Airport) has not been filled in as it was in the case of the Bay Area's 511.org. Clicking on the light rail map itself produces a highly interactive map of the rail system. Click- ing on the icon for the airport station produces a complete description of services and amenities at the airport station. In theory at least, the transit operator could create a first page that is specific to the needs of those who come to the site from the hyperlink on the airport website. As it is, a very good sum- mary of the services of the airport rail station is provided via a relatively indirect path: airport website to light rail line page to interactive map to station details provided via the interactive map. As it stands, the user of the airport website may or may not succeed in navigating to the transit agency's airport station information page. Ground Access Information on the Boston Airport Website Passenger Information Provided by the Airport The website for Boston's Logan International Airport also has the Airport Wayfinder(tm) graph- ics system, a portion of which is devoted to showing ground transportation departure locations at
