• Abstract:
  The aim of this study is to provide a preliminary assessment of Louisiana’s high-speed urban arterials in terms of existing pedestrian crossing facilities and identify any associations of pedestrian crashes with the presence or lack of such pedestrian crossing facilities. In achieving this aim, several tasks were undertaken including: documenting pedestrian crossing facilities and which is appropriate for a roadway type; documenting how other states have defined high-speed roadways and recommending a definition for Louisiana; documenting policies governing provision of pedestrian crossing facilities on high-speed arterials; documenting legislation prohibiting pedestrians on roadways other than interstates; documenting classification of an area into urban, suburban, or rural categories and recommending a roadway categorization of Louisiana’s high-speed urban arterials for the purpose of this study; documenting data types and studies required for the provision of several pedestrian crossing facilities, and identifying pedestrian crash locations and how they correlate to certain roadway features. To achieve this objective, this study looked at nine study areas that make up Louisiana’s urban and urbanized areas: New Orleans, Baton Rouge, Lafayette, Shreveport, Houma, Monroe, Alexandria, Hammond, and Lake Charles. The research team compiled and analyzed data from a database of crash data between 2013 and 2017, GIS data from DOTD that provided roadway information, and aerial view roadway features extracted from Google Earth. The analyses undertaken include data-driven safety analysis to identify any correlation between pedestrian crash frequencies and roadway characteristics, and also with intersection/non-intersection features; spatial hotspot or heat map analysis to visually identify hotspots of high pedestrian crash locations and whether they correlate with bus stop locations; decision tree analysis to identify significant influencing variables that impact pedestrian crash frequency; and location movement classification method analysis to understand how different pedestrian and motorist movements correlate with pedestrian crash frequencies. The outcome of this study is a preliminary assessment upon which a follow-up study can be undertaken that will evaluate the impact of providing appropriate countermeasures, install and evaluate before and after studies analysis, and develop a statewide guideline for the provision of pedestrian facilities on Louisiana’s high-speed arterials.
