Using Python, BeautifulSoup, and Urllib2 I scraped ticket price information from a specific Megabus route for the upcoming 60 days.
Weekends vs. Weekdays
When I plotted the average ticket price for each day there was a clear difference between "weekdays" and "weekends".
Average Ticket Price Weekends (Fri-Sun): $22.24 Weekdays (Mon-Thurs): $9.57
I highlighted weekends in green to differentiate from the blue weekdays.
There are two outliers in the next few weeks, on Friday, 8/31, and Monday, 9/3. These higher ticket prices coincide with the holiday weekend, Labor Day.
Looking at the weeks between 9/7 and 10/7, a pattern for the week emerges. Sunday is the most expensive journey of the entire week followed closely by Friday.
I am presuming that because these weeks are so uniform and they are about two weeks out from when I collected this data, that these are the "standard" prices that the pricing algorithm starts out with when there isn't a high demand for tickets. The only outliers seem to be on the weekend of 9/20 - 9/24. I'm not sure why the Thursday and Monday tickets are priced differently when the weekend tickets are priced the same as normal.
Although I think that the algorithm starts out with Sunday being the most expensive day, over the entire 60 days of data that I collected, it seems that Friday is slightly more expensive. This may be due to the decreased price of the Sunday tickets on Labor Day weekend.
Later I plan to automate this script to repeat this several times a day so that I can see how the listed prices might change over time.
