5 History of ITS Dan Corey s Slide 6

6 What Your Peers are Saying Focus on Operations Improve Incident Management Implementing Active Transportation and Demand Management (ATDM) Strategies Prepare for Connected Vehicles 7

7 Role of TxDOT s TMCs Major TMCs (AUS, DAL, FTW, ELP, HOU, SAT) Monitor Roadways and Devices Provide Situational Awareness Provide Traffic Management Aide in Incident Management Support Other TMCs 8

8 Importance to TxDOT GOAL - Statewide Focus - # 1 in Safety, Mobility, Efficiency, Accountability Operations Can Address Over 40% of Congestion Reduce Secondary Incidents Reduce Incident Timeline Reliable Service 9

10 Trends Active Arterial Operations Asset Management Performance Management Traffic Management Tools Performance measures are becoming an important tool in driving new and improved traffic management strategies. Decision Support Systems 12

11 Active Arterial Management CCTV Camera Monitoring Signal Timing Refreshing Equipment Failure Reporting Freeway-Arterial Integration Signal timing refreshing every 2-3 years is beginning to transform into a real-time operations. Transit Signal Priority 13

12 Asset Management Enterprise System GIS Bar-Coding Remote Access Shared Inventories Proactive Life Cycle Mgmt Asset management tools are beginning to be used to replace outdated equipment before it becomes a problem. 14

13 Performance Management Incident Management ITS Device Availability Traveler Info Activity Quality Control Benefit-Cost Ratio Performance measures are useful in both a static and real-time mode. 15

16 TMC Strategies Signal Operations Freeway Operations Performance Measures Ramp Metering Managed Lanes TMC staff are beginning to apply real-time performance measures to continuously improve operations. 18

17 Signal Operations Active Arterial Operations Multiple Detection Sources ATMS Applications Adaptive Traffic Control Performance Measures There is a need for traffic engineers to have a presence in TMCs to fuse the various sources of information available to improve signal system operations. 19

19 Freeway Operations Real-time performance measures are beginning to be posted on video walls, at operator workstations and on control room side walls. Incident Management Work Zone Management Special Event Management Emergency Management Performance Measures 22

20 Ramp Metering Warrants Algorithm Enforcement Public Outreach While ramp metering algorithms are designed to be automated, traffic engineers in the control room should review applicable performance measures to fine-tune their operations. Performance Measures 24
