The Evolution of CTSO’s

Strategic Approach and

Alignment with AASHTO’s New

Strategic Plan

Page 7: CTSO Subcommittee on Operations 2021 Annual Meeting

7

The Evolution of CTSO’s Strategic Approach

• CTSO’s 2018 Strategic Plan was created to “focus on transportation operations and

emerging technology with a goal of improving safety, system operations, and

highway system performance.”

• At its inception, the Plan established nine goals for which one or more CTSO

Working Groups were responsible and formalized a range of activities addressing

the importance of operations and technology in support of TSMO.

• In 2020, CTSO’s leadership introduced seven cross-cutting themes to help facilitate

collaboration among the CTSO Working Groups and Community of Practice on

Road Weather Management, all with the purpose of mainstreaming TSMO and

integrating its role and impact to improve safety and enhance the management of

the transportation system.

Page 8: CTSO Subcommittee on Operations 2021 Annual Meeting

8

CTSO’s Seven Cross-Cutting Themes

• The cross-cutting themes provided the basis for a range of collaborative activities

across the WGs, with attention to:

1. CAT/TSMO alignment,

2. Research to build on existing practices,

3. NOCoE’s role to encourage outreach and knowledge transfer,

4. Capture of best practices to benchmark TSMO,

5. The value of ROLF and the Operations Manual as foundational to the TSMO workforce

and effective practices,

6. Alignment of TSMO and safety, and

7. The importance freight operations within TSMO.

• Each Working Group prepares its action plan with the themes in mind. Their reports

during this week’s meetings reflect this.

Weaving CTSO Action Plan with

AASHTO’s New Strategic Plan

The following web tool: Strategic Plan Actions (strategic-plan-actions.herokuapp.com) shows all AASHTO committees, their strategies,

and their actions, and it includes downloadable Excel files for each committee with all this information. The following slides are screen shots of CTSO’s action items that have been incorporated into the

AASHTO Strategic Plan.

What’s Next—Part 1: Request for NCHRP Funding to Develop a New CTSO Strategic Plan

• There are two objectives for this research project. First, is to develop a new, comprehensive strategic plan to frame CTSO’s purpose and direction. Second is to review and refine CTSO’s action orientation throughout the year to carry out its plan.

• This project will build on the 2018 CTSO Strategic Plan, 2021-2026 AASHTO Strategic Plan, NCHRP 20-123(12) System Mobility and Emerging Technologies (SMET): Strategic Planning Session and Research Roadmap Development, and NCHRP 20-102: Research Roadmap for Impacts of Connected Vehicles and Automated Vehicles on State and Local Transportation Agencies.

• The proposal was approved by CTSO’s Research Coordinators and CTSO Chair and submitted on August 18, 2021.

Page 14: CTSO Subcommittee on Operations 2021 Annual Meeting

What’s Next—Part 2: Incorporating Diversity, Equity, and Inclusion into CTSO’s Strategic Thinking• First created in 2018, CTSO’s Policy and Procedures for Diversity, Equity

and Inclusion include: Definitions for Diversity, Inclusion, Equity, and Bias;

Procedures to Enhance Diversity, and Procedures to Enhance Inclusion and

Equity.

• The AASHTO Board of Directors approved a resolution addressing Race,

Equity, Diversity, and Inclusion Policy Resolution PR-2-20) in November 2020

• Plans are underway to create a Special CTSO Task Force for Diversity,

Equity & Inclusion that will update CTSO’s Policy and Procedures on Diversity,

Equity, and Inclusion and will also review and align with 1) the AASHTO BoD

Resolution on DEI and 2) the AASHTO Strategic Plan.

Strategic Planning and Research Roadmap Kick Off

• Currently Underway• NCHRP Project 20-123 Research Proposal Discussion:•Joint Subcommittee on System Mobility and Emerging Technologies (SMET) Strategic Planning and Research Roadmap Development•

• Funding Program: NCHRP 20-123 (AASHTO Committee Support)

• Project Purpose:

• Develop a comprehensive strategic approach and action plan to coordinate the activities of the joint subcommittee on system mobility• and emerging technologies activities that AASHTO, TRB and FHWA can use to guide their future activities.

• Develop a longer-term research strategy to continue to advance the state of practice in system mobility and emerging technologies

• Funding Amount: $225,000

• Project Scope:

• In light of the AASHTO CPBM and CTSO Strategic and Action Plan, it is important that leadership of these two groups come• together to conduct a strategic planning session where specific needs (and related strategies and actions) can be discussed• and a path forward is developed that identifies needed resources, support, meetings, conferences, and research. The need• to do this now is urgent as an overall direction for the joint subcommittee is needed.

• The task is more complex due to the nature of joint subcommittees and involves aligning two standing committees and their respective strategic plans and research agendas. In addition, SMET seeks to be a clearing house for similar topics for AASHTO groups and committees to further leverage resources and effort. The results from the strategic planning session will also be used todevelop a research roadmap that will identify needed research projects and integrate these research needs into existing researchroadmaps already developed by CPBM and CTSO

Michigan DOT Real-Time Warning System

Safety benefits:

• Know When to Pay Attention: Static

signs may go unnoticed. Michigan’s

systems are activated only when

conditions are/may become slippery.

• Take Action: RTW systems alert drivers

to specific road conditions, prompting

them to reduce speed and use extra

caution.

• Noted 38 percent reduction in crashes

per year, no deaths or injuries, and

observed vehicles slowing to a safer

speed when RTW is activated.

• April 2021

• Objective to collect information on State DOT efforts to

deploy RTW and VSL

• 18 participants from 9 State DOTs and AASHTO

• Michigan, Ohio, and Utah DOTs presented on their

RTW/VSL solutions

• Group dialogue:

▪ Why was RTW/VSL deployed on this corridor?

▪ What were the steps for planning/development/deployment?

▪ What functionality/technology was required?

▪ Were there any key lessons learned?

Page 53: CTSO Subcommittee on Operations 2021 Annual Meeting

53

Listening Session: Findings

• Common motivations:

▪ Known weather hazards

❖E.g., fog, areas prone to snow/ice, etc.

▪ High crash rates tied to weather events

▪ Alternative infrastructure fixes are expensive

❖E.g., modifying infrastructure to reduce hydroplaning

▪ Improve safety and mobility for law enforcement and

maintenance (snowplows, etc.)

Page 54: CTSO Subcommittee on Operations 2021 Annual Meeting

54

Listening Session: Findings (cont.)

• Deployment approaches:

▪ Automated activation for basic systems in remote areas

❖E.g., “ice on bridge when flashing” beacon sign and ice detector

▪ Manual activation for complex systems

❖E.g., dynamic messages, variable speed limits

❖Need to have system to determine when to manually deactivate

Page 55: CTSO Subcommittee on Operations 2021 Annual Meeting

55

Listening Session: Findings (cont.)

• Best Practices:

▪ Prioritize investments based on weather hot spots and severity

▪ Use crash databases and heat mapping to identify areas of high

weather-related crashes

▪ Look for good benefit-cost ratios and reduced UDC

▪ Place RWM investments in long-range planning projects

▪ Couple RWM strategies in project scoping with other capital

investments

▪ Calibrate equipment frequently to maintain accurate detections
