District 1 Enhanced Signal Head Visibility Risk - A custom python toolbox developed by JMT is used in ArcGIS Pro to determine enhanced signal head visibility risk scores at signalized intersections along FDOT-managed roadways in District 1.
To prioritize locations for enhanced signal head visibility, each signalized intersection is assigned a risk score. The risk score is calculated for each signalized intersection as determined by the following criteria: total rear end crashes, total red light running related crashes, approach speeds, AADT, and percent trucks.
This countermeasure analysis result layer and JMT-managed source data layers are to be updated by JMT only upon request of District 1 stakeholders. Source datasets for the analysis include District 1 Signalized Intersections (produced by JMT with data provided by District 1), FDOT Maximum Speed Limit, AADT; and Crash Data from 2015-2019. Note that the FDOT-managed source data used in the analysis was downloaded from FDOT's TDA website in file geodatabase format by JMT in May 2022; thus the currently displayed FDOT-managed reference layers may be out of sync with the analysis source data.
