7 Weather

8 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.

10 Boardings vs Ave Temp AM Average, Direction = 1

11 Dwell vs. Ave Temp AM Average, Direction = 1

12 Trip Time vs. Ave Temp AM Average, Direction = 1

13 Boardings vs. Precipitation AM Average, Direction = 1

49 Regression Dwell Regression Model I have run several of these..here is an example Dwell = *No. Boardings *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.

50 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…
