Xinyi (Elynor) Zhou
## Warning: package 'ggplot2' was built under R version 3.2.4The 2012–2013 Delaware Valley Regional Planning Commission’s (DVRPC) Household Travel Survey (HTS) collected household travel data across nine counties of the Delaware Valley region. The travel data was recorded in four documents: Household, Person, Vehicle and Trip. The Trip file is the data file used for mode choice analysis. A total number of 61724 (unweighted, unfactored, nogo excluded) trips were recorded among the 81940 entries in the trip data from 20,216 individuals. Of the 61724 trips recorded, 88.2% were non-work trips, and 11.8% were work trips (shown below).
## # of trips frequency
## non-work trip 54413 0.8815534
## work trip 7311 0.1184466The determination of work/non-work trips depends whether the trip destination was Work out of the four destination types categorized in the study (Home, Work, School and Other). Two special scenarios were also considered when categorizing work/non-work trips:
- Short trips made during work, such as returning from lunch with Work as the destination
This type of trip has the pattern of Work-Other-Work. The Other-Work segment of the trip is considered as non-work trip even the destination was Work.
- Park & ride
This type of trip has the pattern of Other-Other-Work where Other-Other contains activities of Change type of transportation/transfer. The Other-Other segment of the trip is considered as work trip even the destination was not Work.
The following tables and charts show the mode choice for work and non-work trips. To represent the total number of people in the study area using data from the travel survey population, person-level weights were calculated as part of the survey and was used in the analysis to show the mode choice results below.
