Estimated Load vs. Passenger Movement

Weather

Interesting to note the below average passenger boardings in the summer and x-mas week Need to calculate the average by quarter or by month, since the summer is a distinct season

9
I tried to normalize the data, creating a summer and non-summer period to account for the lower ridership over the summer…not sure if the dates I picked for the normalization are the best. In this chart, summer is June, July or August. I could probably be more precise to match the school year.

Regression Dwell Regression Model I have run several of these..here is an example Dwell = 6.09 + 3.54*No. Boardings + 1.97*No. Alightings R squared =.291 There are interesting differences in the dwells for timepoint stop locations versus regular stops. Travel Time Regression Model I am still experimenting with this. The thought was that we can explain as much variation as possible with the bus data…what we can’t explain would be road conditions/congestion. It would be interesting to compare routes (low and high congestion routes) to test this assumption. I have achieved an R squared of about.19 Most of the variation is explained by passenger movement and dwell.

Notes Headway variance Subplots of headway variance and estimated load Subplots of headway variance and boardings/alightings Table of summary statistics to re-plot in excel »See if what I did worked… »Also experiment w/different ways of displaying the timepoint names (i.e. a legend) Dwell regression model With stop locations W/O stop locations Dwell Circle Running time: arrive time(x) – leave time(x-1) Layover time: hmmm… Dwell time: dwell, less layover (?) Stop circle time: leave_time - arrive_time, less dwell (?) Travel time regression model Plottools function in Matlab, which you call from the command line, is very handy for manipulating figure formats…
