3. Safety Data Guidance: Where is It?
23 U.S.C. 148(f)(2):
- Establishes a subset of the MIRE that are useful for the inventory of roadway safety; and
Ensure that States adopt and use the subset to improve data collection
Ray - The HSIP Final Rule, which went into effect April 14, 2016, outlines the “Fundamental Data Elements” that constitute subset of MIRE.

4. Model Inventory Roadway Elements
Serves as a guideline to help transportation agencies improve their roadway and traffic data inventories
Provides a basis for a standard of what can be considered a good/robust data inventory
Helps agencies move towards the use of performance measures
About to release MIRE Version 2.0
Recommended listing of roadway inventory and traffic elements critical to safety management

5. Subset of Model Inventory of Roadway Elements (MIRE) to be Collected - FDEs
For non-local paved roads (37elements split into)
Road segment elements
Intersection elements
Interchange/ramp elements
For local paved roads (9 elements all dealing with)
For unpaved roads (5 elements all dealing with)
Subset enables jurisdictions to analyze crash experience of roadway networks relative to the expected average crash frequency given roadway and traffic characteristics at specific locations

In addition to the Technical Assistance available through the Resource Center and Safety R&D’s STAC, the RSDP has several technical assistance programs. Our goal is to be able to meet any kind of safety data & analysis-related technical assistance request.
The first 2 programs (RDIP and RDETAP) address specific issues; the third covers everything else.

7. Roadway Data Improvement Program (RDIP)
Assist States to improve the collection & management of roadway/traffic data elements
What data are collected and how?
How are the data used and by whom?
What data management policies, practices and procedures does the State have in place?
Are the roadway/traffic data able to be integrated with other data (e.g. crash, citation, vehicle)?
What is the quality of the roadway/traffic data?
RDIP would be particularly good for States reviewing their data programs and/or planning/implementing improvements to and/or reorganization of their data programs. In this program, a team of technical experts spends several days in the State reviewing data programs, sharing insights from other States, and offering recommendations.

8. Roadway Data Extraction Technical Assistance Program (RDETAP)
Deliver technical assistance to state and local agencies on methods of identifying, extracting, integrating and reformatting roadway data from existing resources (video logs, Google Earth, Bing)
RDETAP to deliver accurate and consistent roadway data for use in analytic models

9. Safety Data & Analysis Technical Assistance Program
Open to all states and local agencies or their representatives
Matched with subject matter experts
Range of services available:
One-on-one consultations
Peer exchanges on-site or web based
Technical workshops
This is our most basic and flexible program.

10. Training National Highway Institute HSM Suite 38000 Web-based training

11. Safety Data & Analysis Training
New NHI training being developed:
Safety Data and Analysis Fundamentals course
Pilots for 3 states and/or local agencies in Fall 2017
Analysis tool courses:
Safety Analysis of Freeways and Interchanges
Overview of the new HSM Chapters 18 & 19
Safety Data and Analysis Fundamentals
(Under development)
Transportation Performance Management for Safety
2-day workshop explores how geometric design, traffic control, and other factors affect roadway safety. The agenda provides and overview of the new HSM Chapters 18 & 19 and guidance on how to use ISATe and/or the IHSDM to analyze freeway/interchange safety.

12. Data-Driven Safety Analysis (DDSA) Initiative
Goal: Integrate safety performance into ALL transportation investment decisions
Jerry
EDC = Every Day Counts. EDC’s goal is to identify and rapidly deploy proven but underutilized innovations to shorten the project delivery process, enhance roadway safety, reduce congestion and improve environmental sustainability.
What is the Data-Driven Safety Analysis Initiative?
Its the application of two science-based analysis approaches, into two common transportation processes.
The two approaches that we’re referring to are Systemic and Predictive, and will talk about those in greater detail in a moment.
The transportation processes we’re talking about include Safety Management (which is probably no surprise to anyone), BUT THE OTHER IS Project Development, because we believe that safety performance should be integrated into ALL highway investment decisions.
For this EDC-3 initiative, will be primarily focusing on design decisions, such as Alternatives Analysis, Design Exceptions, and would also include Performance-Based Practical Design.

13. The application of the latest evidence-based tools and approaches
What is DDSA?
The application of the latest evidence-based tools and approaches
to safety analysis
Provides reliable estimates of an existing or proposed roadway’s expected safety performance
Helps agencies quantify the safety impacts of transportation decisions, similar to the way agencies quantify:
traffic growth
environmental impacts
traffic operations
pavement life
construction costs
DDSA is the application of the latest evidence-based tools and approaches to safety analysis.
These approaches use crash, roadway, and traffic volume data to provide reliable estimates of an existing or proposed roadway’s expected safety performance.
DDSA helps agencies quantify the safety impacts of transportation decisions, similar to the way agencies quantify:
traffic growth
environmental impacts
traffic operations
pavement life
construction costs

14. DDSA can be applied throughout the Project Development Process…
So where can DDSA be applied in the Project Development Process? Really, it can be applied throughout, and we’ve tried to boil it down to four broad stages. It can be applied in planning, alternatives analysis, design, as well as construction, operations, and maintenance.

15. Roadway Safety Data Capability Assessment
Evaluate states ability to execute data driven safety analysis and performance measurement
Enable FHWA to track progress of states ability to collect, analyze, and manage roadway safety data
Roadway Inventory and standards
Data analysis tools and uses
Data management and governance
Data interoperability and expandability
4 Pilots will be completed by July

17. Safety Data and Analysis Toolbox
Web resource to help users identify appropriate tools based on their needs and capabilities
Organized by task
Collect, Analyze, Manage, Research
Types of tools
Software, Data bases, Guides & Information sources
Key Message:
Roadway Safety Data and Analysis Toolbox, and
Develop a series of individual tools that will reside in the Toolbox.
The individual tools are written documents—starter kits, primers, informational report, how-to guides, decision-support guidebooks, training materials, or software that will assist State and local agencies in roadway safety data collection; development, refinement, and management of their safety data system; and use of the data in safety analyses supporting performance-based planning, safety management, and project development decision making.
The Toolbox will be a web-based structure for organizing information and guiding users in selecting the tool best suited to the job at hand. The structure should accommodate currently available roadway safety data and analysis tools, documents developed under this Task Order, and additional tools developed beyond this Task Order. The Toolbox should be a one-stop shop for all levels of users to learn about and access roadway safety data and analysis tools.
