Great job finishing your analysis on traffic indicators. The above summary of your major findings was really helpful. Did you consider adding the above summary to your project introduction?
You may have already answered this since you listed weather as a major contributor to traffic volume but is there a way to look at the time data on the bad weather days. Maybe since it will rain or snow, people adjust their schedule and do errands earlier or at different times or go to the store more to stock up on supplies.
Great explanation of dataset and your analysis approach. Great job using markdown cells to provide more details about your analysis.
Great use of histogram charts to compare day and nighttime traffic volume. You did a great job adding charts to explain your analysis. You may consider adding a chart title to Out  line plot and Out  line plot.
Great job explaining inconsistencies in the data set:
From this we can see that between rows
177 , We’re missing 4 to 5 hours of time. That’s why we have a difference in the number of rows in the dataset.
Great explanation of the traffic volume range and the percentile breakdown: This made the project analysis easy to follow and did a great job of guiding me through your analysis:
The traffic volume varried from 0 to 7,280 with an average of approximately 3,260 cars hourly.
Only 1,193 cars or fewer passed the station for every hour around 25% of the time, this most likely happens at night or during road construction. However, around 75% of the time, traffic volume was four times as high with about 4,933 cars or even more than that. From this observation, we are going to analyze and compare the data in terms of daytime and nighttime

Minor spelling errors:
Markdown section above In 
original sentence - The station records westbound traffic only wich
spelling correction - The station records westbound traffic only which
Markdown section above In 
original sentence- experienced mostly during the winter time between Nivember
spelling correction - experienced mostly during the wintertime between November
Markdown section below In
original sentence - difference in the nubmer
spelling correction - difference in the number
In  and In  may be self explanatory but you may consider adding inline comments to explain your code.
In  print statement is explained in the markdown following In  but you may consider adding a little more description as to what the print result means
daytime ==> (23877, 9)
nighttime ==> (24327, 9)
As you can see, there is a difference in the nubmer of rows, where daytime rows are less than that of nighttime rows. This might be because of some missing data in the dataset.
Great job and I enjoyed reading your project!
