Transcription

1 Overview of AIRPORT CURBSIDE AND TERMINAL-AREA ROADWAY OPERATIONS (ACRP Project 7-02) 2009 ACI NA Operations and Technical Affairs Conference Peter Mandle Jacobs Consultancy March 17, 2009

2 Agenda Research objectives Use of research results by airport staff and others Use of QATAR Contents of tool box 1

3 Research Objective Objective: Prepare a guide for the analysis of airport curbside and terminal-area roadway operations Guide should include: 1. Recommended and quantifiable performance measures 2. Easily used and valid analytical tools and models that predict curbside & roadway operations 3. Guidelines for evaluating curbside & roadway operations 4. A toolbox of measures to improve curbside & roadway operations 2

4 The Guide Responds to Customer Requests Should be useful to airport staff Should not require extensive input data Provide a hierarchy of tools: Quick-estimating tools, macroscopic and microscopic analyses Validate available simulation models Create and validate new analytical models (QATAR) for: Analysis of curbside operations represents interaction between through traffic and traffic in curbside lanes Analysis of low-speed weaving represents low-speed weaving maneuvers for various weaving types 3

5 Application of Hierarchy of Tools and Models Hierarchy of Analytical Tools Performance Measure Quick Estimating Macroscopic Analysis Microsimulation Analysis 1 Quick Plan Reviews 2 Preliminary Estimates of Requirements 3 Estimate of Roadway/Curbside LOS 4 Operations Analysis - Standard Geometry 5 Operations Analysis - Non-Standard Geometry 6 Detailed Operations Analysis 7 Average Speeds and Delays/Queue Lengths 4

6 Recommended Performance Measures Terminal-Area Roadways Highway Capacity Manual (HCM 2000) performance measures (LOS) are applicable for: Entry/exit roadways Re-circulation roadways Service/delivery roadways Weaving areas (adjusted for low-speed operations) Signalized and non-signalized intersections HCM performance measures are not applicable for curbside roadways Curbside LOS determined by lowest LOS of either: Vehicles stopped to pick up / drop off passengers Vehicles traveling past stopped vehicles 5
