AASHTOWare Safety Segment Analytics is a cloud-based SaaS platform that connects to external databases to receive crash, vehicle and occupant data, roadway data, asset data, as well as any other data supplied by the licensing agency, to power a number of purpose-built applications. Agencies can customize various configurations (countermeasure logic, Crash Modification Factor (CMF) values, and various calculations) to meet their unique needs. AASHTOWare's Safety Segment Analytics provides analysis based on data for roadway segments. AASHTOWare Safety Segment Analytics includes four modules:

1. Crash Query: The Crash Query application allows users to create custom queries to search crashes in a GIS interface. A number of search variables, including crash type, vehicle, occupant, roadway, or geographic criteria can be used to refine queries in natural-language search terms. Users can explore crash details, including recommended countermeasures, to help with crash mitigation. Crash Query can generate shareable PDF Crash Reports with the click of a button.
2. Safety Analysis: The Safety Analysis application allows users to conduct segment-specific analysis to see where crashes are occurring, and what countermeasures can be put in place to minimize crashes. Safety Analysis allows users to generate benefit-cost calculations in seconds with built-in service life and CMF values. Safety Analysis will also generate a shareable PDF Safety Report with the click of a button, complete with recommendations or specified treatments. Users can easily generate a Safety Report on every project and at every phase of the project.
3. Network Screening: The Network Screening application empowers users to rank their roadway network using Segments, and Sliding Window analyses by crashes, fatalities, crash ratio, crash rate, crashes per mile, or any other desired calculation, with just the click of a button. Custom filters can be applied to refine the scope of your analysis, targeting regions, counties, cities, or even custom geographic areas. The module also allows filtering by contributing factors, or even potential countermeasures to help agencies to determine which roadways need the most attention. With the click of a button, users can generate a shareable Network Screening report to share this data with anyone internal or external to the users’ agency.
4. Safety Performance Functions (SPF) Manager: The SPF Manager is key to understanding expected crash rates, which give agencies insight into how their roadways are performing. Agencies can use SPFs that they have already created to run their analysis. Alternatively, SPF Manager can create custom Safety Performance Functions for an agency. In addition to creating/saving SPFs, SPF Manager provides a history of the functions that can help provide analysis for how SPFs are performing.

Additionally, each application includes a connection to external data sources, as well as built-in data warehouse functionality, which enables the “joining” and transformation of various datasets that power AASHTOWare Safety Segment Analytics.

The AASHTOWare Safety Intersection Analytics builds on the segment-level data made available under the applications included in AASHTOWare Safety Segment Analytics. With the addition of AASHTOWare Safety Intersection Analytics, each application can be configured to incorporate intersection data as well. This tool provides valuable insight into intersection related crashes, safety improvements, and network screening analyses. The AASHTOWare Safety Intersection Analytics adds Intersection related data and analyses for the following four (4) modules:

1. Crash Query: With the addition of intersection data to Crash Query, users can query, explore, and generate intersection-related crash and vehicle level data, as well as generate crash summary and comparison reports with the click of a button.
2. Safety Analysis: Safety Analysis - Intersections allows users to conduct corridor analysis, which includes both segment, and intersection analysis. The intersection-specific analysis allows users to see what crashes are occurring, and what intersection-specific countermeasures can be put in place to minimize intersection crashes. Users can generate benefit-cost calculations in seconds with built-in service life and CMF values. Safety Analysis will also generate a shareable PDF Safety Report with the click of a button, complete with recommendations or specified treatments, which allows users to easily generate a Safety Report on every project and at every phase of the project.
3. Network Screening: Network Screening - Intersections empowers users to rank their roadway network Intersections by crashes, fatalities, crash ratio, crash rate, or any other desired calculation, with just the click of a button. Apply custom filters to refine the scope of your analysis, targeting regions, counties, cities, or even custom geographic areas. Filter by contributing factors, or even potential countermeasures to help your organization determine what intersections need the most attention. Generate a shareable Network Screening report with the click of a button, to share this data with anyone inside, or outside your organization.
4. SPF Manager: With SPF Manager - Intersections, agencies can use SPFs that they have already created to run their analysis. Alternatively, SPF Manager can create custom Safety Performance Functions for an agency. In addition to creating/saving SPFs, SPF Manager provides a history of the functions that can help provide analysis for how SPFs are performing. By providing Expected Crash Rates and Excess Crashes, intersection SPFs would improve the way intersections are understood and evaluated in Crash Query, Network Screening, and Safety Analysis.

The AASHTOWare Safety Trend Analytics allows users to create custom dashboards to visualize any element of their data in an easy-to-use, and easy-to-share format. Create secure dashboards to share within your organization, or publicly available dashboards to share data with the public through public portals, a public-facing URL allowing for open access to any desired Workbook, with no user limit, or authentication required. AASHTOWare Safety Trend Analytics provides custom workbook creation and sharing through the following two (2) modules:

1. Workbooks: The workbooks application provides users with a full business intelligence platform. The Workbooks application utilizes the roadway, crash, and safety data present in the other AASHTOWare Safety offerings, allowing users to generate and share custom Workbooks to visualize their agencies roadway safety data. This robust data visualization platform can also be used to generate custom, exportable PDF reports to share data with internal, or external stakeholders.
2. Public Portals: The public portals feature of the Workbooks application allows agencies to share custom charts and workbooks through a public-facing URL. Agencies can use this tool to create custom dashboards and share data with key external stakeholders, or the public at-large.

AASHTOWare Safety Analyst integrates all parts of the highway safety management process into a single software package. AASHTOWare Safety Analyst includes five analysis modules:

1. The Network Screening Module identifies sites with potential for safety improvements. It includes an option to use a variety of severity levels and any crash attribute as screening criteria. Measures of effectiveness and statistical methodologies are used to provide a more a reliable list of locations warranting further investigation.
2. The Diagnosis and Countermeasure Selection Module is used to diagnose the nature of safety problems at specific sites and assist users in selecting effective countermeasures to address those problems. It facilitates thorough diagnosis through basic collision diagramming and identification of significant crash patterns, and systematic countermeasure selection through site-specific diagnostic questions.
3. The Economic Appraisal and Priority Ranking Module performs an economic appraisal of countermeasures or alternative countermeasures for a specific site, an optimization of sites and countermeasures, and a priority ranking of alternative improvements. Optional benefit methodologies are provided to support requirements of the federal Highway Safety Improvement Program.
4. The Countermeasure Evaluation Module provides the capability to conduct before/after evaluations of implemented safety improvements. New statistical methods provide valuable feedback on the effectiveness of completed countermeasures for reporting and future planning.
5. The Systemic Site Selection Module is used to identify the most appropriate sites for implementation of a selected countermeasure. The module incorporates network screening procedures to identify sites with crash patterns that can be remedied by the countermeasure selected for implementation and then economic analysis procedures are used to identify the most cost effective locations to implement the countermeasure given a specified budget.

Safety Analyst also provides the capability to generate performance monitoring reports that enable the user to monitor the overall safety performance of an agency’s highway network or any subset of the highway network. Performance monitoring reports provide results that document safety performance during specified years and can generate year-to-year comparisons in performance. Performance monitoring reports include standard descriptive statistics, such as crash frequencies and rates, as well other performance measures that highway agencies may wish to track in monitoring progress in implementing their statewide or regional safety plans. Safety Analyst makes use of safety performance functions (SPFs) in many of its analytical methods and tools. Default SPFs are provided in Safety Analyst and automatically calibrated using an agency’s data. Safety Analyst also provides the capability to input agency-specific SPFs in multiple functional forms for use in the analytical methods and tools. The software is currently being updated to provide the capability for SPFs to vary between geographical regions within an agency’s geographical boundaries, where there is reason to believe that roads in those regions have inherently different safety performance. For example, users might want SPFs to differ among:

• highway agency districts or regions
• user-defined groups of counties
• regions with differing terrain
• regions with differing climate
• any other user-defined regions that vary substantively in safety performance

AASHTOWare Safety Analyst Sunset Plan

• AASHTO intends to sunset AASHTOWare Safety Analyst on June 30, 2022. A number of factors led to the decision to sunset. The Safety Analyst software is now 18 years old and has reached the end of its technology lifecycle. That reality and the decreasing level of adoption and use by the state departments of transportation in recent years has made on-going development or product upgrade unsustainable.
• AASHTOWare will continue to provide support and maintenance through June 30, 2022, however no enhancements will be made to the software during the sunset period.
• Any member agency that continues to license Safety Analyst through the sunset period, may elect to receive the source code by executing a source code agreement after June 30, 2022.
• A new AASHTOWare Safety product is available for agencies wishing to consider an alternate solution in this business area. Please refer to the AASHTOWare Safety product description elsewhere in this catalog for more information.
• Additional information may be obtained by contacting Ryan Fragapane, AASHTO Associate Project Manager, at (202) 624-3632 or by e-mail at rfragapane@aashto.org.
