TOOLBOX ON INTERSECTION SAFETY AND DESIGN: DATA COLLECTION AND ANALYSIS FOR IMPROVED OPERATIONS

This paper on data collection and management is from a set of conference proceedings on Intersection Safety: Achieving Solutions Through Partnerships (March 2004, Irvine, California). The paper highlights efficient methods of crash data collection, addresses important issues related to managing crash data and integrating crash data with other useful databases, and demonstrates how a robust crash data management system can be used to optimize a safety engineer's limited resources. The authors describe an analytical approach that empowers safety engineers and analysts to proactively identify specific intersection safety problems rather than respond to citizen complaints after accidents have occurred. This approach includes multi-year trend analysis, temporal analysis (seasonal trend, day of week, time of day), identification of driver behavior crash patterns, incorporation of demographic data, and methods to identify crash patterns. The authors also address the importance of building effective, collaborative relationships with law enforcement agencies (where much of the crash data originates) and with political and governmental agencies. The authors encourage readers to go beyond the use of relational database management software and contemporary GIS platforms, to incorporate other data sources into an agency's crash data management system. These sources can include traffic operations data, signal control plans, work program histories and priorities, land use and special generator data, and aerial and street-level imagery. The authors conclude with an outline summary of the recommended procedures to use.
