• Key Office Locations in North America – Atlanta, Chicago, DC Area, Los Angeles, Vancouver, Toronto
• Hong Kong Office – Established in 1987 – Focus on ITS work – Consultant services in ITS planning and design – ATMS/TMC turnkey contracts
4 Hong Kong
5 • A British crown colony since 1840’s • Returned to China in 1997 as a Special Administrative Region (HK SAR) • Population – 7M+ • Area – 426 square miles with a hilly terrain • Vehicle ownership – 700,000
6 HK Strategic Road Network
1. Overview of Route 8 TCSS Design
7 HK ITS (TCSS)
• Tend to be project-specific • Some PPP but mostly government funded • Called TCSS (Traffic Control & Surveillance Systems) • Mostly bridge and/or tunnel control systems with sophisticated functions including ATM • Field equipment intensive • Monitors also a variety of non-traffic devices • Maintenance and operation included in system planning

Lion Rock TCSS
13 HK Airport TCSS
• Ground Transportation Management System – Lane Control – Departure Signs – Parking Signs – Integration • Flight Database • Building Services • Car Parks
14
Route 8 – Hong Kong
• $50M TCSS Supply • DIG Joint Venture – Delcan, Imtech, GTech • 2900 Devices – FVMS, VSLS, LCS, PVMS, WW, TOR, EMT, CCTV, OHD, VD, SEC, AC, BAT, MCB. • Interfaces – CMCS SCADA – TMCA TCSS – Hong Kong Transport Dept – TIS
16 Overview of Route 8 TCSS
R8 network:
• 13.5 km (8 ml)
• Second longest span cable-staged bridge in the world
• Three tunnels
• One enclosed roadway
• One toll plaza
17 R8 – Shatin Heights
ROUTE 8 – SHA TIN HEIGHTS TUNNEL R8 – Eagle’s Nest Tunnel
ROUTE 8 – LAI CHI KOK VIADUCT R8 – Stone Cutter Bridge
ROUTE 8 – STONECUTTERS BRIDGE R8 – Nan Wan Tunnel
ROUTE 8 – INTERCHANGE ABOVE CT9 RECLAMATION Functions of R8 TCSS • Multiple control centers • Dynamic lane control and management • Contraflow • Variable speed limit with harmonization • Incident/queue detection and management • Interface with tunnel environmental systems • Interface with Tsing Ma TCSS) • Rule-based traffic response plans • Monitors a variety of non-traffic devices • NTCIP standards partially adopted
22
R8 TCSS – Field Equipment • Control over 1800 traffic field devices
• Also monitor other field equipment, such as tunnel barriers and emergency phones
23 Interface with Adjacent TCSS

26 On-Screen Traffic Statistics
27 Traffic Management
• Automatic Incident Detection (AID) Algorithm • Incident Management • Traffic Management Response Plans – Sequenced Multiple Aspect Change – Operator Assistance: Advise/instruct – Traffic Plan Step-through, Preview and Simulation • Safety Interlocking Check • Traffic State Analysis
28 Automatic Incident Detection (AID)
• Multiple algorithms can run at the same time – APID (All Purpose Incident Detection) • California Family of Algorithms – High Occupancy (HIOCC) – Low Speed – Compression Wave Detection – Queue Detection – McMaster • Video detection integration – stop vehicle – wrong way vehicle – low speed
29 Incident Management
30 Route 8 TCSS
Rule Based Plans (possibly the largest RBP project in the world) • Location independent rules • Resolve sign utilization conflicts Pre-defined Plans • Tunnel Operations – Contra-flow • Emergency Operations – Fire • Wind/Weather Operations – Warnings • Over-height Vehicle – Automatic Integrated with over 1000 traffic signs/signals • Full Matrix VMS’s (15) • Variable Speed Signs (160) • Tunnel Lane Signals (488) • Matrix Lane Signals (332) • Variable Direction Signs (131) 31 Pre-determined Plan

34 Rule-Based Logic – FVMS Example
• Sign Selection: Rule Stage 1: Select appropriate FVMS • Message Determination: Rule Stage 2: Select FVMS Message Templates e.g. INC Rule Stage 3: Fill-in Variables
{Blockage Pattern}{Blockage Type} {EventLocation}
LEFT LANE BLOCKED BEYOND EXIT 1B

TEMPLATE CODE MESSAGE TYPE DEFAULT PRIORITY
SFT Soft Response 1 Increasing Priority CIW Caught in Weather 2 QUE Queue 3 CIQ Caught in Queue 3 INC Incident 4 CII Caught in Incident 4 CLS0 Caught in Closure 5 CLS1 Closure 1 (Before First Exit) 5
CLS3 Closure 3 (Ramp/Exit Closure) 5 STP Stop 6
36 Safety Checks
• The system checks every signal control defined in the plan or any manual controls against a safety interlocking matrix and safety rules like – two slanting arrows pointing to each other – consistency between the displays on signals and signs on the same or adjacent gantries
37 Safety Checks
• All changes in field equipment are monitored for safety violation • Safety rules can be “hard” or “soft” • Other safety features: – lane restriction on double-deck bridge – speed fluctuation on roadway – precaution procedures for co-ordination of execution of traffic plans among multiple control centres.
