Statewide County-Level Traffic Crash Modelling Using Land-Use Data: A Case Study of the State of Florida in the United States

Although many macroscopic studies have been performed until now, few studies have attempted to find out land-use factors for traffic crashes based on highly aggregated geographic units such as county levels. Thus, the main objective of this study is to identify factors contributing to traffic crashes from land-use data based on county-level geographic units. In order to achieve this objective, land-use data in Florida in 2012 was obtained from the Florida Department of Revenue. This land-use data includes agricultural, industrial, institutional, mining, public, recreation, residential, retail/office, and so forth. A series of Poisson Gamma models were estimated for various crash types and revealed significant land-use factors for traffic crashes. Moreover, counties with high traffic crash risks were identified using PSI (Potential for Safety Improvements) and visualised using GIS techniques. It is expected that policy decision-makers and transportation planners are able to understand how land-use can affect traffic safety in long-term transportation planning. Furthermore, it is possible to consider traffic safety in land-use planning and proactively provide appropriate traffic safety treatment for various crash types using the results from this study.
