This is an interactive map presenting the crash frequency in the section between km 319.8 and km 322 of the BR-101 Federal Highway in the city of Niteroi after the inauguration of an additional lane for each traffic bound. A Kernel Estimator was used to illustrate the occurrence of crash hotspots, while the georeferenced red dots carry valuable information on the number of accidents per type (i.e., Property Damage Only, Injury Crash, Pedestrian-Injury Crash, and Fatal Crash) occurring along the road. Finally, the sum of Standard Severity Units of each point is calculated according to the methodology proposed by the Brazilian National Plan of Crash Control and Traffic Safety, which is presented as follows: SSU = sum(1 x PDO + 4 x Injury Crash + 6 x Pedestrian-Injury Crash + 13 x Fatal Cash) Where: SSU: the number of Standard Severity Units at a particular location; PDO: the number of Property Damage Only crashes; Injury Crash: the number of crashes where at least one person other than a pedestrian got injured; Pedestrian-Injury Crash: the number of accidents where at least one pedestrian got injured; Fatal Crash: the number of accidents with at least one death.
