What is the Work of Safety Planning?
SEMCOG LRP Safety Goal and Objectives Promote a safe and secure transportation systemPromote a safe and secure transportation system Reduce traffic crashesReduce traffic crashes Increase safety for transit ridersIncrease safety for transit riders Address roadway incidentsAddress roadway incidents Develop pedestrian friendly communitiesDevelop pedestrian friendly communities Assist local communities in defining safety needsAssist local communities in defining safety needs
Crash Data Analysis Start with state police crash dataStart with state police crash data Identify high-crash locationsIdentify high-crash locations –Frequency –Rate –Equivalent Property Damage Only (EPDO) –Relative Severity Index (RSI) –Crash Probability Index (CPI) Examine crash typesExamine crash types Identify solutions/optionsIdentify solutions/options Perform cost/benefit analysisPerform cost/benefit analysis
Crash Data Analysis continued Use GIS (combining crash with other transportation planning data)Use GIS (combining crash with other transportation planning data) –Road geometrics (width, configuration) –Traffic volumes –Congestion –Land use –Pavement conditions –Census
Elderly Crashes and Population Fatal Injury Property Damage Only
SEMCOG Safety Tools used by Local Governments SEMCOG Traffic Safety ManualSEMCOG Traffic Safety Manual –Step-by-step instructions/worksheets –Regional peer group critical values –Lists of potential mitigating measures (includes crash reduction factors and O & M costs) –Benefit /cost analysis SEMCOG Transportation Data Management ToolSEMCOG Transportation Data Management Tool –Includes 6 years of crash data –Create community crash profile reports –Search and report on intersections and segments (high- crash intersection ranking lists, detailed reports) –Create crash maps
