1 Importance of ITS Preventive Maintenance and Transitioning to an Accelerated ITS design Approach for Illinois Tollway September 14th, 2018 Amarpal Matharu, PE, MBA Traffic Operation Manager, Illinois Tollway Michel Lavigne, P.Eng, MBA ITS Director, Illinois Tollway General Engineering Consultant Ardmore Roderick

2 Agenda ITS Infrastructure ITS Preventive Maintenance Program Cost Benefit Analysis Transitioning to an Accelerated ITS Design Phase

3 ITS Infrastructure Device type additions Total Percentage Increase Closed-circuit television (CCTV) 1, ,111 10% Dynamic message signs (DMS) % Lane-use control signs (LCS) Vehicle detection systems (VDS) % Roadway weather information stations (RWIS) % Weigh-in-motion (WIM) % Flashing beacons % Total devices 1, ,990 37% 3

4 ITS Preventive Maintenance History : Reliability-centered maintenance Was repair when needed In 2015 Started PM on DMS as pilot 2014: ITS maintenance contractor (Meade Electric) 2017: Parson to manage ITS maintenance contractor 2018: Contract for ITS PM on CCTV, MVDS and DMS as pilot

5 Preventive Maintenance: CCTV Preventive Maintenance includes Inspection of the pole structure Clean camera dome Inspect dome and housing Report any anomaly Results Older cameras showed water and bugs intrusion PM enabled better planning and maintenance Reduces response time and cost to each issue

6 Preventive Maintenance: VDS Vehicle detection systems types MVDS In-pavement VDS Bluetooth Preventive maintenance includes MVDS: Manual vehicle count per lane and travel speed compared to MVDS data In-pavement VDS: Monitor battery life of wireless sensors Results Increases reliability and accuracy Provides accurate travel time

7 Preventive Maintenance: DMS Visual inspection of DMS site and display; replace parts if needed Full diagnostic of DMS sign through controller Inspect and clean DMS sign and cabinet Testing and maintenance of batteries Verify power supply for any sign of failure Repair and/or replacement of components

8 Preventive Maintenance DMS Issues & Preventive Maintenance by Year Number of Tickets for Issues or Issue Issue (39) (39) (46) (56) (64) (Number of DMS on the Tollway system for each year)

9 2018 Preventive Maintenance Contract - Pilot Conducted PM on 196 ITS Devices 140 CCTV: 19.3% (27) required replacement 53 MVDS: 28.3% (15) were out of alignment 3 Type 1 DMS : After 1 year in service they required replacement of air filter, due to high concentration dust from road construction

10 ITS Maintenance Costs by Device ITS device replacement cost at the end of its lifecycle Portion of various additional maintenance costs: ITS maintenance staff (Tollway and consultant) Material and labor for ITS device replacement

11 ITS Maintenance Costs Analysis 0.0% 5.0% 10.0% 15.0% 20.0% 25.0% Pole-mounted CCTV 19.9% Tower-mounted CCTV (200') 3.1% Microwave Vehicle Detection System 10.9% In-Pavement Vehicle Detection System Bluetooth Vehicle Detection System 0.2% 0.9% Walk-in Dynamic Message Sign 13.4% Front Access Dynamic Message Sign 1.6% Roadway Weather Information System 3.4% Weigh-in-Motion 6.1% ITS Enclosure (cabinet) 19.5% Fixed Security Camera 4.5% Lane Control System (I-90) 16.5%

12 Benefits of ITS Preventive Maintenance Increases reliability and functional lifespan of all ITS devices Reduces downtime and cost of repair for critical equipment Reduces long-term replacement costs Maximum benefits of ITS equipment to support Traffic Operations Center

13 ITS Benefits ITS for Benefits Illinois for Tollway Illinois Tollway Estimated benefit-to-cost ratios: by U.S. DOT ITS Joint Program Office ITS device Lowest industry-estimated benefit-to-cost ratios CCTV 7.6 : 1 Roadway weather information System 1.8 : 1 Weigh-in-motion 6.0 : 1 Vehicle-detection systems 4.5 : 1 Dynamic message sign 2.0 : 1

14 Summary for Preventive Maintenance Program Reduces maintenance frequency and costs; PM outside peak travel hours Increases the lifespan of each ITS device and long-term replacement costs Improvements in operational performance Enhance reliability of the overall system

15 Accelerated ITS Design Approach 15

16 Accelerated Design ITS Systemwide Program Opportunity to accelerate design work Identify ITS sites into typical sites and non-typical sites Benefits of methodology 16

17 Design consists of typical sites and non-typical sites 9 categories of typical sites: C1 CCTV on fiber and AC (replace CCTV) C2 CCTV and MVDS with fiber and AC (replace device) M1 MVDS on cellular and solar power (replace MVDS only) M2 MVDS on cellular and solar (remove and replace on CCTV pole) M3 MVDS on fiber and AC (replace MVDS only) M4 MVDS on cellular and solar (convert site to fiber and AC) P1 Ramp plaza camera connected to data cabinet P2 Ramp plaza camera connected to plaza building R1 RWIS on AC and cellular

18 Non-typical site design differences The work for non-typical locations is shown on site-specific plan sheets Site-specific sheets detail information regarding power runs, communications runs and barrier warrant analysis Schedule of quantities table is created on each site-specific plan sheet Site-specific locations needed more analysis to locate each new pole
