Abstract:The Alabama Department of Transportation (ALDOT) led the effort to develop ALSAFE, a spreadsheet-based safety tool that can be used for short and long-range transportation safety planning. ALDOT developed ALSAFE to serve as a safety planning tool for Metropolitan Planning Organizations (MPOs). The short-range planning process allows MPOs to develop benchmarks and performance measures, evaluate crash trends and patterns, and identify potential countermeasures for further evaluation. The long-range planning component of ALSAFE provides predictive equations to estimate changes in crash frequency or severity influenced by area-wide planning characteristics.
