ระบบขนส่งผู้โดยสาร (APM)


According to Suvarnabhumi Development Plan

                      • SAT-1 will be built south to NMTB.

                      • Automated People Mover will be the only transportation of  passenger among two terminals.

 

 

Unique Characteristics of an APM

                     -Fully automated & driverless transit system

                     -Exclusive right of way / guideway

                     -Tunnel in BKK

                     -Proprietary system by each supplier – not interchangeable

                     -Performance Specifications are the Industry Standard for procuring APM systems

                    -Varying system characteristics & facility design

                    -Best addressed by early procurement of the APM

 

Cable-Propelled – Typical Characteristics

                    -Cable Propelled (no on-vehicle motors)

                   -Cable under car, in guideway

                   -10 - 120 passengers / vehicle

                   -Passive vehicle (only housekeeping electrical)

                   -Rubber tire, steel wheel or air-levitated §Elevated, at-grade or tunnel

                   -Requires rooms for drive & return sheaves

                  -Can be inside a building (DTW & NDIA)

                  -Detachable grip & switches now available

                  -Historically: short shuttles (~ 1 km)

                  -Now: up to 5 km / pinched loops possible

 

Self Propelled – Typical Characteristics

  -Electrically self-propelled (traction motors or LIM)

                      -Rubber tire, steel wheel- steel rail, maglev

                      -Bottom supported

                     -Center or Side Guidance Systems

                     -Elevated, at-grade, in tunnel §Various switch types

                     -40 - 130 passengers / vehicle 1 – 6 cars / train

                     -Easiest for system expansion

                     -Most Typical Airport APM for loop or pinched loop configurations 

 

System Configurations

 

                    -Each has implications for:

                    -Routing complexity

                    -System Types (cable or self propelled)

                    -Networking

                    -Expandability

APM Fixed Facilities

                    -Require Coordination with Fixed Facilities Designers:

                   -Guideway/Tunnel

                   -Running Surface (plinth), Guidance & Switching, and Emergency Walkway typically by APM supplier

                   Stations

                   -Adjacent Equipment Room

                   -Maintenance & Storage Facility (MSF) (or depot)

                  -Central Control (OCC)

                  -Adjacent Equipment Room

                  -Adjacent UPS

                  -Power Distribution Substations (PDS) DC or AC

 

APM Design Process

                 -Project / System Requirements – Established by UCD

                 -System Configuration and General Alignment(s) - initial & future

                 -Service levels - trip times, hours / day, availability 99.5% +

                - Ridership Demand - initial & future

                - Define applicable type(s) of technologies

                -Confirm APM capacity accommodates passenger demand(s)

                -Preliminary Design and Detailed Design

                -Coordinate Requirements/Interfaces with Fixed Facilities

                -Develop performance specifications contract documents

                -Reference Drawings by Fixed Facilities Designers

 

APM - Procurement / Implementation

               -APM System Competitive Procurement Process to Select Supplier

               -Performance Specifications

               -DB or DBOM

               -Fixed Facilities Procurement by Other Contract(s)

               -Conventional procurement (public low bid)

               -Submission and Review of APM Supplier’s Design Submittals

               -In-Plant Manufacturing and Observation

               -On-Site Installation and Observation

              -Acceptance Testing

              -Vehicle/Wayside Testing

              -System Level Testing

              -System Demonstration

              -Safety Certification and Start of Revenue Service/Warranty Period

              -O&M Commences

 

Lessons Learned from Existing APM Systems

              -Competition ensures best value to Owner

              -Performance Specifications allow competition and innovation between multiple APM

               suppliers and are the Industry  Standard

              -The Procurement Process must ensure only Service-Proven Technologies

              -In Order to Achieve Seamless Future Expansion:

              -Expansion by original supplier is almost universal

              -Expansion by third party supplier is problematic

              -Fast-Tracking APM procurement ahead of fixed facilities helps coordination and interface
