Visionzero
From the Analyze Boston webstie, I found another dataset pertaining to accidents and road safety called VisionZero. The aim of this organization is to completely eradicate fatal car crashes in Boston by 2030.
According to this dataset, there is a steady decrease in the number of car crash incidents in Boston since 2015. There is a steep drop observed in 2020 thanks to the pandemic related lockdown, but the frequency jumps back to pre-Covid averages soon after.
The rmse score of Exponential smoothing is 49.399.
Seasonal Decomposition shows a reduction in accidents since 2020. Between 2015 and 2020, the accident rate is shown to be more or less constant.
