Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

8 Guidebook for Developing ramp Control Facilities in HTML format. These can be printed and shared with stakeholders for collaborative discus- sions and decision making. The Decision Support Tool is available for download from the report summary page at Please open and read the “Instructions for Ramp Control Decision Support Tool” file first as it contains instruc- tions for using the tool. As indicated in Figure 3, users can use guidance from all of Chapter 2 to help them populate the Decision Support Tool. Furthermore, guidebook users can access the Decision Support Tool during Steps 1, 2 and 3 as described in the following sections. Once all inputs are recorded in the Decision Support Tool, a report can be generated that summarizes the information from Steps 1, 2, and 3 for review by the airport operator and stakeholders as described in Step 4: Determine the Best Alternative. Users are encouraged to be familiar with all steps in the guidebook prior to using the Decision Support Tool and to pay close attention to the “tool tips” that are provided. This format ensures that the considerations made and the conclusions reached are documented as they are developed and are available for collective review following the evaluation process. Figure 3. How the design support process (this guidebook) relates to the Decision Support Tool. What the Decision Support Tool Does and What It Does Not Do What it does: The Decision Support Tool is an aid that receives inputs from the user and can generate reports in HTML format that can easily be printed and shared with the stakeholders involved with ramp control. What it does not do: The Decision Support Tool does not generate a ramp control decision for a user. It simply provides a report that contains the key factors involved in ramp control decision making.

Decision process and Decision Support tool 9 2.1 Define Ramp-Related Problems (Step 1) The first step in the decision process is to determine what challenges or constraints are occur- ring or projected to occur related to ramp operations at an airport, and to consider potential solutions to mitigate the challenges or constraints. Operational challenges and constraints gener- ally fall into one of four areas of concern—operational efficiency, safety, construction, or admin- istrative. As airport operators consider these challenges, they may discover that ramp-related problem areas overlap. They may also find that they are only acknowledging the symptoms of a ramp-related issue (e.g., a complex airport terminal layout may cause ramp congestion issues that may intensify if new construction increases ramp activity). Some major questions to consider include: • What ramp-related operational challenge(s) or constraints are occurring or are projected to occur at an airport? • Do the ramp-related operational challenges or constraints require action on the part of the airport operator or airport community? • Are suggested ramp-related actions in alignment with executive-level policies (e.g., hiring freeze, budgetary constraint)? • What are the potential solutions to mitigate the operational challenges or constraints? Has a change in operational procedures been investigated? • What lessons can be learned from other airports that have implemented ramp control? The airports that have implemented ramp control are listed in Appendix E. To help illustrate the importance of these types of questions, the scenario in Figure 4 provides a typical situation in which an airport and its stakeholders need to discuss whether there are Figure 4. Example of multiple ramp-related considerations. Example: Multiple Ramp-Related Considerations Scenario: The airport operator and a number of interested stakeholders have determined that growth at the airport is increasing and the trend is expected to continue. In past years, ramp congestion had not been a problem; however, with the increased activity, ATC has noticed a rise in the number of arrivals delayed getting to their gate due to increased traffic. ATC added that the situation is manageable, but some of the airlines noted their on-time arrival performance has been negatively affected. The airport is planning to add an additional concourse, but the construction is not expected to start for another year and may affect existing ramp space during the construction period. Challenges/Constraints: Continued growth is creating ramp congestion. On-time performance is negatively impacted. Construction may exacerbate the problem before improvement is seen.

TRB's Airport Cooperative Research Program (ACRP) Research Report 167: Guidebook for Developing Ramp Control Facilities provides guidance to airport operators considering providing ramp control services. An accompanying

Ramp Control Decision Support Tool

assists users through most considerations before providing ramp control services, including facility requirements, staffing, training, and technology and other factors, allowing the user to determine the best way to move forward.

The Ramp Control Decision Support Tool is implemented in a sequence of HTML files and Javascript libraries that can be navigated using a web browser. The current version of the tool supports Google Chrome and Mozilla Firefox browsers.

In order to use the install and start the tool please use the following steps:

1. Copy the provided zip file with the tool to a local directory.

2. Unzip the contents of the zip file to this directory.

3. Open index.html file using either Google Chrome or Mozilla Firefox.

4. The welcome page provides a general overview of the tool.

5. Click on the Get Started button to start uisng the tool. This will lead to Step 1 questions.

6. Provide responses to questions included in Step 1 and when done click on the Next button.

7. Repeat for Steps 2 and 3.

8. When done answering the questions for all three steps click on Report to automatically generate a report with all provided answers.

9. The report can be printed by clicking on Print button.
