Pedestrian-Injury-Disparity-Index-Analysis
Repository of data, code and supporting materials to repeat analysis performed by ODOT Research Unit documenting pedestrian injury disparities in Oregon. The standardized scoring uses an objective approach to categorizing Census tracts based on race, ethnicity, and poverty. These categories are then used to calculate population-based pedestrian injury rates for the state.
Counts-Processor-in-R
A set of R scripts that to download, process, and clean bicycle and pedestrian traffic counts data starting by pulling data through Eco Counter's API.
Pedestrian-Fatal_Injury_Rate
The data and scripts in this repository gather data from Fatal Accident Reporting System (FARS) and Census data and then calculates a age-adjusted population-based pedestrian death rates for each represented racial group to assess disparities.
Traffic_Injury_Severity
Modeling traffic injury severity as a function of vehicle, roadway and particpant characteristics
Oregon-DAS-Geocoding-in-R
This project includes an example of how to use R and an open API geocoding service operated by Oregon Department of Administrative Services (DAS). More information about the service itself including the meta-data can be found at the link below https://navigator.state.or.us/arcgis/rest/services/Locators/gc_Composite/GeocodeServer
Pedestrian_Counts_From_Signals_R5
This project summarizes data and methods used to estimate pedestrian traffic volumes from short duration counts and pedestrian push actuations at traffic signals
