    The contract objectives include assessing state traffic records systems, providing technical assistance to state traffic records programs, facilitating training for managers and staff of state traffic records systems, and providing user support for NHTSA's State Traffic Records Assessment Program (STRAP) system that states use to undertake their traffic records assessments.

  • Traffic Records Assessment Support (Task Order 1)

    The purpose of this contract is to conduct state traffic records assessments during the period of performance, September 2014 up to September 2019. These assessments require TSASS to furnish and manage facilitators and assessors sufficient to complete these assessments.

  • TRIPRS Power User and Outreach (Task Order 2)

    This project has two main objectives. The first is to provide technical support and training for users of the TRIPRS/STRAP system. This includes providing training and help desk assistance to the facilitators and assessors who conduct traffic records assessments. The second objective is to assist the NHTSA Traffic Records Team to develop policies and procedures for the collection, management, and analysis of data in the STRAP system.

  • Section 405(c) Traffic Records Assessment "Bridge" Support

    The purpose of this effort was to conduct seven assessments during the roughly 7-month period of performance. This required the management of facilitators and assessors to oversee and conduct the assessment, as well as finding new assessors. This contract utilized the new State Traffic Records Assessment Program (STRAP) system, as built by TSASS.

  • Traffic Records Assessments Review

    The main objective of this study was to examine state traffic records programs and systems as documented in their traffic records assessments and to identify potential changes to the assessment process. NHTSA Region and state staff were interviewed to obtain their opinions and observations about the assessment process and state safety data systems changes. As part of this effort, general comparisons were made relative to the types of recommendations made in Assessments from 2000-2009.

  • Traffic Records Strategic Planning Briefings

    Conducted over 100 NHTSA-sponsored briefings of State Traffic Records Coordination Committees for a variety of reasons, including to:

    • Provide an update on national safety data programs and solicit state participation in US-DOT information gathering efforts
    • Provide technical assistance to states and NHTSA Regions related to the implementation of the Section 408 State Traffic Safety Information System Improvement Program
    • Educate states about the Model Impaired Driving Records Information System (MIDRIS) data dictionary and facilitate meetings among stakeholders
  • AASHTOWare Joint Software Development

    TSASS provided facilitator services to the American Association of State Highway and Transportation Officials (AASHTO) in the definition and development of software that is part of the AASHTOWare suite of programs. This software provides state and local governmental agencies with an interface between a wide range of transportation safety data capture and analysis tools, as well as legacy data systems within the agency, while providing a common interface for the sharing of application tools and data.

  • Roadway Inventory and Linear Referencing System Standard

    As a cooperative effort between FHWA and AASHTO, and in support of the TSIMS effort, a project was formed to develop a standard for roadway inventory and linear referencing systems. This project, led by AASHTO with funding support from FHWA, relies upon an advisory group from various state, federal and local agencies around the U.S. to provide guidance and consensus to the development effort. At key points within the project, open meetings where others with an interest in the effort were given the opportunity to address the working group.

  • BTS Traffic Safety Data Warehouse and Research Project

    This effort assisted BTS in the development and implementation of the traffic safety, or highway component of the Intermodal Transportation Safety Database (ITDB) and resulted in the availability of this data through the TranStat web site. This effort was one part of a larger project to collect, standardize and warehouse traffic safety data as obtained from States. It included the following tasks:

    • Collection of traffic safety data files from States.
    • Design of standardized data structures for traffic crash, driver license, vehicle registration, roadway inventory and supporting tables for inclusion within the TranStat system.
    • Development of data migration routines to map State data files to standardized files as maintained within the TranStat system.
  • Property Damage Only

    This study was commissioned by the National Highway Traffic Safety Administration through its Driver License and Traffic Records Section to attempt to obtain current information on under-reporting: magnitude, causes and possible ways to reduce it.

  • Evaluation of Bicycle Crashes Data Collection by Law Enforcement

    The National Highway Traffic Safety Administration (NHTSA) commissioned a review of current practices for the collection and analysis of bicycle crash data, with a specific focus on the law enforcement officer accident report process. Interviews with bicycle safety professionals, bicycle advocates, law enforcement officers, and traffic safety data professionals yielded much of the data, as well as some existing documentation and a survey of state Police Accident Reports (PAR).

  • Traffic Records Team Website

    The Traffic Records Team website provides technical information, data, resources, and guidance in data collection and management to the traffic safety community at the local, state, and national level. The NHTSA Traffic Records Team strives to assist and support this community, leading to better decision making, improved communication, and a larger network of support. The following items represent a few areas on the website:

    • Crash Form, EMS, and Citation-Adjudication Catalogs: A United States map and list of states are contained on this page; click a state to view information about data systems for which we have information. Each state page contains data system tabs at the top; click the tab which you wish to view.

    1. The Crash Catalog is on-line inventory of all crash forms has been maintained since year 2000. This site contains printable versions of the crash forms as well as any available crash data dictionaries and officer coding manuals. Where available, links are provided to state-maintained crash fact websites.
    2. The EMS Catalog Includes information about NEMSIS participation status, contact info of state EMS and Medical Directors, manuals, forms, data dictionaries, and links to state EMS websites.
    3. The Citation-Adjudication Catalog Contains basic information about the state's citation-adjudication system.
  • NHTSA Model Impaired Driver Records

    The goal of this endeavor was to elaborate on the information in the Federal Register notice to produce a full data dictionary for a model impaired driver information system, including core functional specifications. This document was developed as a collaborative effort of federal and state specialists in this area. Technical assistance was offered to states and NHTSA Regions, usually in the form of meeting facilitation and arranging for speakers who had built systems in their own states.

  • Association of Transportation Safety Improvement Professionals (ATSIP)

    ATSIP is a nonprofit 501(c) 3 organization with a mission to further the development and sharing of traffic records system procedures, tools, and to promote professionalism in the field of traffic records.

  • Safe Communities

    For a number of years, NHTSA provided grants to communities that created a traffic safety committee or coalition composed of engineering, enforcement, and EMS/health under what were called Safe Community Grants. These programs were created and funded to bring together multiple disciplines for the purpose of reviewing local traffic safety problems and identifying collaborative countermeasures to reduce traffic deaths, injuries, and losses. All of the programs were required to do an analysis of local traffic crash data to establish patterns, trends, and areas in need of safety countermeasures. TSASS was contracted by a number of these programs around Ohio to provide them with local traffic crash data and the analysis of that data to help guide and evaluation the local safety programs that were funded by NHTSA.

  • Regional Injury Surveillance Systems

    TSASS worked with several regional hospital and EMS groups to develop and operate regional injury surveillance systems. These systems were composed of pooled and sanitized data from hospital data sets, trauma registries, and EMS datasets along with crash data for the region. Data was provided to TSASS in its native form, translated to standardized formats, and placed into regional databases. The data within the regional systems was masked for personal identifiers and data source. Data was linked between the various data sets to provide composite information from the point of injury to the point of discharge from the hospital. Data was made available back to the sources, allowing them to compare internal data to the larger data pool, while protecting the privacy of the data source and the individual. Clients included hospitals and EMS services in Northwestern, Eastern, and Northeastern Ohio.

  • Hospital Data Processing

    As a spinoff and supporting function to regional injury surveillance system work done by TSASS, a number of hospitals contracted with TSASS to take hospital discharge data sets and convert that data to formats required by Ohio DPS and uploading that data as an agent for the hospital to the Ohio Statewide Trauma Database. This data was also typically incorporated by the regional injury surveillance systems.

  • Crash Data Scrubbing and Analysis

    Since approximately year 2000, TSASS has been providing local MPOs and counties with services that fall into the general category of crash data scrubbing, location, and analysis. For these clients, TSASS takes the crash data as obtained from the Ohio Department of Public Safety (DPS), corrects common coding and keying errors, locates it to the local roadway network, and performs various statistical analyses of the data. In the support of the local safety programs, TSASS develops high-hazard location listings, collision diagrams, crash trend analysis, and produces local traffic crash facts books and summaries. This is typically done at the jurisdiction-wide level as problem identification tool and at specific site or detail level to support safety project countermeasure selection and funding applications.

  • Crash Safety Studies

    TSASS provides site-specific analysis support to local political subdivisions and traffic engineering firms within Ohio. We have begun to work with firms using the Traffic Engineering Manual procedures and reports. These support services may include but are not limited to: identification and scrubbing of crashes for a particular site or corridor, development of collision diagrams (optional with aerials), development of ODOT traffic accident analysis reports, provision of crash data associated user friendly with ODOT’s CAM Tool, and crash data and reports required for various funding applications.

TSASS staff has participated in assessments of nearly all 56 states and territories.

  • Data System Design, Build, and Maintenance

    TSASS staff has been involved in the creation and maintenance of several data systems, from conceptual design, build, and maintenance.

  • State Traffic Records Improvement Program (STRAP)

    The National Highway Traffic Safety Administration (NHTSA) offers a comprehensive approach for assessing State traffic records data based upon the Traffic Records Program Assessment Advisory. Developed by a group of national subject matter experts, the Advisory describes the ‘ideal’ traffic records system and provides a set of questions to assess the capabilities and characteristics of a State traffic records system. States are compared to the Advisory using an online system where states answer questions, which are then graded by assessors. Three rounds of question and answer are supported. The final product is a report to the state that outlines accomplishments and areas of opportunity.

  • Traffic Records Improvement Program Reporting System (TRIPRS)

    TRIPRS contains detailed information on all projects contained in the strategic plans submitted by the states and U.S. Territories. Users may view the project name, detailed project description, lead agency, milestones, performance measures, baselines, and planned budget information. This is a restricted access area; select state personnel are granted access to their state's information only, NHTSA Regions are granted access to all states within their region, and select USDOT personnel have read access for all states.

  • Data Improvement Projects Clearinghouse

    The Data Improvement Projects Clearinghouse was a clearinghouse for information on traffic safety data system improvement efforts at the federal and state level, and to support the internal needs of NHTSA and the states for tracking and monitoring the data improvement efforts within each state. It contained a public view of the project data contained in TRIPRS, and contained only project descriptions containing no sensitive data and the project manager and their contact information.

  • Traffic Records Systems Inventory

    The Traffic Records Inventory (TRI) allowed users to navigate by system or state to find information about state traffic records systems. The TRI was provided as a service to the public, and in particular those within the highway safety community. It represented the best available information about each of the traffic safety data systems within each state and territory.

  • Bureau of Transportation Statistics (BTS) TranStats State Safety Data

    TSASS worked with states and BTS to migrate state safety data files (vehicle registration, driver license / history and traffic crash) to the BTS TranStats web site as part of their Intermodal Transportation Data Base.
