Slide 1: Georgia Department of Transportation: Performance Measures — A Case Study in Progress
Slide 2: Introduction
- Vision
- ITS Deployments
- Weekly Report
- Framework
- User Interface Preview
- Challenges
- Questions
[This slide contains a graph of the breakdown of traffic info calls by roadway. The bars for Interstate 285, I85 and I75 all show about 20% of the calls are about these three roadways. There is also a picture of traffic along a highway system and the inset picture is a picture of an accident. The third picture is of a yellow strip running along the middle of the highway.]
Slide 3: Vision
"The purpose of measuring is not to know how a business is performing but to enable it to perform better." (I-95 Corridor Coalition)
[This is slide contains pictures that characterize the few steps involved in the performance measure process from Output to Outcomes.]
Slide 4: ITS Overview
[This slide contains a map of Georgia and breaks out the state’s seven districts by color. Each district is numbered and ordered by the amount of traffic in that area. The Atlanta Metropolitan Area has more than 50% of the state’s traffic concentrated in that area.]
Slide 5: ITS Overview — TMC
[This slide contains a picture of the Traffic Management Center room.]
Slide 6: ITS Overview — Field Equipment
- 487 CCTV Cameras
- 1645 VDS Cameras
- 548 Video Processors
- 86 Radar Units
- 135 Message Signs
- 25 Network Hubs
- 145 Ramp Meters
[This slide contains pictures of filed equipment in the throughout the state. This slide also contains a map of where equipment is located geographically by using symbols.]
Slide 7: Current Performance Measures
[This slide contains eight screen shots of Georgia DOT’s weekly performance measures report. Each screen shot measures a different type of performance such as breakdown of calls, traffic operations statistics, and traveler information statistics.]
Slide 8: Framework
[This slide contains a picture of GADOT’s Performance Measure Framework used to develop the new performance measures. The framework consists of three pillars built on two foundational underpinnings.]
Slide 9: Framework: Foundation
[This slide contains a drawing of the ITS Systems Engineering framework and the Continual Process Improvement overlaying the GADOT’s Performance Measure Framework.]
Slide 10: Framework: Pillar I — Outcomes
Three Initial Categories
- Mobility
- Safety
- Customer Services
Three Types of Outcomes
- Congestion
- Incidents
- Customer Satisfaction
Many possible variables impact each Outcome
[This slide contains a drawing that demonstrates pillar one or outcome in the Performance Measure Framework. It demonstrates traffic variables are funneled through the Performance Measure Process and lead to an outcome called congestion.]
Slide 11: Framework: Pillar II — Outputs (Activities)
- TMC activities are one of the variables that impact Outcomes
- Output metrics measure TMC activities
- Output metrics need to be traceable to Outcomes
[This slide contains a drawing that demonstrates pillar two or outputs in the Performance Measure Framework. It demonstrates how output performance measures are funneled through the performance measure process and traceable to outcomes like congestion.]
Slide 12: Framework: Pillar III — Context
- Outcome Metrics have Spatial attributes
- Outcome Metrics have Temporal attributes
- Outputs should contain these attributes to support traceability between Outputs and Outcomes
- Other Contextual Variables should be captured
[This slide contains a drawing that demonstrates pillar three or context in the Performance Measure Framework. There are screenshots of a map and calendar.]
Slide 13: Framework
[This slide contains a drawing of the of the Performance Measure Framework showing the foundation of our framework overplayed by the iterative ITS systems engineering process and the Continual Process Improvement. The three Pillars are located at the top of the foundation and indentify the Outcome metrics followed by development of Output metrics that can be linked to desired outcomes through the support of Temporal, Spatial and Environmental Context.]
Slide 14: User Interface Preview
[This slide contains a screen shot of the web-based dashboard in the User Interface Preview mode. The dashboard displays a map displaying road segments, layer control, Outcome metrics control, a temporal filter, and charts and gauges for Output measures.]
Slide 15: Challenges
- Budget
- IT support
- Public Perception Data
- OTD Data conflict
- Upper Management Alignment
Slide 16: Review
- Vision
- ITS Deployments
- Weekly Report
- Framework
- User Interface Preview
- Challenges
[This slide contains a graphic that demonstrates a recap of GADOT’s Performance Measure Vision.]
