Presentation Focus
“why you implemented performance measures in the first place and what you get out of them…”
as it relates to Maryland TSM&O/ Mobility/ Reliability Improvement efforts
3
TSM&O at SHA
• Existing Business Processes at SHA have stable TSM&O components built-in at all levels across the agency
• SHA Recipient of FHWA SHRP2 L06 Implementation Assistance to “Organize for Reliability” – opportunity to review and refocus priorities
• CMM workshops facilitated TSM&O related conversations internally and externally. Outcome of the L06 project will be a SHA TSM&O Strategic/ Implementation Plan
4
TSM&O Performance Measurement Action Items
• Develop TSM&O data business plan• Develop and implement a travel time reliability
monitoring program• Develop modeling plan and tools for supporting TSM&O
analysis• Other related initiatives (e.g., WZPMA, Freight Fluidity)
Level 1 — Performed 2 — Managed 3 — Integrated 4 — Optimized
Criteria Some outputs measured and reported—but not utilized
Output data used regularly for after-action debriefings and improvements; data easily available and dashboarded
Outcome measures identified (networks, modes, impacts) and routinely utilized for objective-based program improvements
Performance measures reported internally for utilization and externally for accountability and program justification
SHA Self Evaluation in the Performance Measurement Dimension
5
TSM&O Key Opportunity Areas
• TSM&O as a program (similar to SHSP)• Integrated freeways and arterial systems M&O• Arterials Ops is the next big opportunity area• Freight consideration and multi-modal aspects• Performance Metrics that considers ICM, ramp
metering and other strategies• Performance metrics that compares traditional
projects with TSM&O projects• Risk/ Uncertainty analysis tools
6
Performance Data Resources for TSM&O Plan Implementation
Advanced data/performance measurement and analytics infrastructure is already in place SHA Data Services
ATR/ HPMS/ Counts Detector data Signal data/ CCTV feeds Asset data, Project data
UMD CATT/ RITIS/ VPP Speed, Incidents, Workzones,
Special Events, Weather, Transit etc.
8
TSM&O at SHA – Outcome Focused
SHA Policies, Programs and Projects focus on Annual User Cost Savings
Outcome driven decisions – e.g CHART expansion to 24/7 operations
9
TSM&O at SHA – Outcome Focused
CHART Operations• Incident Management
– Annual User Cost Savings– Average Incident Duration
• Traveler Information Systems– # of CHART Controllable Cameras– # of Maryland 511 Calls Received
• Work zone Management• Winter Weather Operations• Special Event Management• TIM Training

Improving Reliability on Maryland Highways
SHAs FOUR-STEP APPROACH
CAUSES OF UNRELIABILITY Poorly Timed Traffic Signals
Inclement Weather Crashes
Fluctuations in Demand Work Zones
SHA developed a Reliability Roadmap in Summer 2014
Phased Approach to develop a comprehensive program that improves reliability of our system
SHRP2 Projects (L38, L06, R11) help advance Roadmap task activities.
11
Communicating Performance thru DashboardsSHA Mobility Dashboard
• Web-based Solution • Performance Based Approach• Increase Transparency

Use of probe speed data to understand the congestion and reliability of the transportation network.
15
Use of Probe Data Analytics UMD CATT, RITIS, VPP Suite, SHA I-TMS
• Probe Data Analytics provide:
– Travel Time & Reliability Analysis– Real-time & Historic Dashboards– User Delay Costs– Animated Historic maps– Region and state-wide Bottleneck Ranking– Performance Summary Tables– Graphics and Data Exports– Raw & aggregate Data Downloads
• Tools and Applications aid in– Identify problem areas (for project development)– Confirm existing project viability– Conduct before & after studies– Create system performance report-outs, and more
