Safety Analysis Tools

In addition to conducting research, HSIS resources are also used to develop products that can be used by practitioners in the analysis of safety problems.

FHWA Pedestrian and Bicycle GIS Safety Analysis Tools
Geographic Information System (GIS) software turns statistical data such as accidents and geographic data such as roads and crash locations into meaningful information for spatial analysis and mapping. In this suite of pedestrian and bicycle safety tools, GIS-based analytical techniques have been applied to a series of pedestrian and bicycle safety issues. The tools included in this suite can be used to develop the following:

  • high pedestrian crash zones
  • safe routes for walking to school
  • safe bicycle routes

FHWA GIS Safety Analysis Tools
Computerized crash analysis systems in which crash data, roadway inventory data, and traffic operations data can be merged are used in many state and municipalities to identify problem locations and assess the effectiveness of implemented countermeasures. By integrating this traditional system with a geographical information system (GIS), which offers spatial referencing capabilities and graphical displays, a more effective crash analysis program can be realized.  The analysis tools include five separate programs to evaluate crashes:

  • Spot/Intersection Analysis
  • Strip Analysis
  • Cluster Analysis
  • Sliding-Scale Analysis
  • Corridor Analysis

Pedestrian and Bicycle Crash Analysis Tool (PBCAT)
The Pedestrian and Bicycle Crash Analysis Tool (PBCAT) is a crash typing software product intended to assist state and local pedestrian/bicycle coordinators, planners and engineers with improving walking and bicycling safety through the development and analysis of a database containing details associated with crashes between motor vehicles and pedestrians or bicyclists. One of these details is crash type, which describes the pre-crash actions of the involved parties. After developing a database of crash information, PBCAT users can analyze the data, produce reports, and select countermeasures to address the problems identified by the software.
