Safety-related Programs and Services

Overview

A presentation on safety data resources available in Iowa (2.3 mb pdf).

Iowa Traffic Safety Data Service (ITSDS)

The ITSDS provides timely access to crash data analyses and reports generated by a variety of safety and GIS-based tools. Some of these tools, like Intersection Magic, are off the shelf. Others have been developed by the Iowa DOT and CTRE. Graduate students on staff respons to agencies' requests with information in various data and graphic formats.

 

Safety Data Tools

The Iowa DOT is the lead for the FHWA's National Model for the Statewide Application of Data Collection and Management Technology for crash records. Many safety data-related tools developed by CTRE for the Iowa DOT contribute to the state's effort to collect, share, and integrate data statewide.

Officer Information Manager

The Officer Information Manager technology, a key component of the National Model, automates the completion of driver- and vehicle-related reports by law enforcement officers in the field using pen-based computers.

Incident Location Tool

The incident location tool uses geographic information systems software to provide users with a map-based computer screen for entering crash data. It's one part of a larger data collection and management technology system that approximately 200 Iowa agencies are using to share safety information. The incident location tool was originally developed for the Iowa DOT. The tool has also been adopted by several other states including South Dakota, Florida, Georgia, Delaware, and New York.

Incident Mapping and Analysis Tool (IMAT) and Crash Mapping and Analysis Tool (CMAT)

These tools analyze crashes throughout the state with set criteria. Local agencies use IMAT. CMAT is used to analyze crashes from the statewide crash database.

Accident Location and Analysis Systems (ALAS)

For several years, CTRE has been involved with developing several iterations of location and analysis tools, from PC-ALAS to GIS ALAS and Access ALAS. The Safety Analysis, Visualization, and Exploration (SAVER) tool developed by the Iowa DOT is the final product.

Emergency Response Information System (ERIS)

The ERIS consists of GIS databases of local emergency response agency boundaries and attributes for the state of Iowa. A pilot project involved the emergency management systems and fire districts in 22 counties.

Safety-related Research

CTRE conducts a variety of safety-related research. See a list of projects with links to abstracts and project reports.

Four-Lane to Three-Lane Conversion

Research and papers about this safety technique, also known as "road diets," that has been successfully implemented in Iowa.

Smart Work Zone Deployment Initiative (SWZDI)

This pooled-fund group of Midwest states researches better ways of controlling traffic through work zones. CTRE began administering this program in 2005.

Traffic Safety-related Publications

CTRE's list of traffic safety-related publications includes brochures, practical manuals/handbooks, research reports, and newsletters for safety-related associations.
