Seamless Intermodal Transit Systems
In the coming decades, linking aviation and rail transportation systems into a more efficient and seamless intermodal system will not only be a convenience, but a necessity. With the advent of unprecedented growth in air travel, airports worldwide are challenged to match their "landside" capacity with that of the "airside," and to do so in innovative, effective, attractive, and economically feasible ways. For the first time, airports with terminals, parking, and roadway access at or near capacity, are struggling with the impacts of landside limitations on their airside passenger operations. To ensure convenient ground access to and from the airport, at some airports landside improvements have taken on the same level of importance as airside improvements.
Enter the rail-aviation intermodal passenger facility. These stations, whether bringing passengers from light rail, heavy rail, commuter rail, automated guideway, or from multiple modes into the airport, have become a central strategic solution used by transportation engineers to support long-term plans for achieving sustainable increases in airside volume while maintaining existing airport boundaries and terminal operations, Even if they only achieve a 4 percent share of passenger travel to the airport, rail-aviation passenger stations can make the difference between flowing traffic on airport access roads, and gridlock.
|The figure on
page 6 depicts the Safety Certification Process described in the handbook.
Major safety certification activities are identified on the left side of the
chart. Rail transit system life cycle phases are shown on the right side.
The handbook encourages developers of rail transit projects to identify the safety activities to be carried out during each phase of the transit project, including:
• Commitment and philosophy to actively sustain safe and secure transit operations.
• Integration of the safety and security function during design, testing, and startup phases.
• Assignment of organizational safety and security responsibilities.
|• Development of safety and security design
• Hazard management process.
• Process for verifying conformance with specified safety and security requirements during design, in equipment and materials procurements, and during testing/inspection and startup phases.
• Formal, final safety certification to enter the revenue phase.
• Construction safety management activities.
• Implementation schedule for meeting State Safety Oversight (SSO) requirements and approvals.
• Waiver application to FRA for transit operations sharing corridors with the general railroad system.
