OP-16: Employee Commute Modal Split

Data was collected from 11/15/09 to 11/21/09. Data averaged from 11/16 to 11/19 was used to complete this section, as few or no classes are held on Friday, Saturday, and Sunday, and so not enough employees were on campus to provide a representative sample. Employees also had the option to respond "Did not work", "Worked from home/off campus" or "Other". The percentages of employees who selected those options were 3.4, 2.4, and 3.8, respectively. These were not included in the calculations above. The original calculations for the above options were: Walk, bicycle, or other non-motorized means - 9.3% Van or carpool - 4.5% Campus shuttle or public transportation - 14.9 Drive alone - 61.8% The original numbers were each multiplied by 100 an divided by 90.5 (the sum of the original 4 percents). In the end, it was 100.1%, so .1 was subtracted from the answer for 14.9 because it has the lowest number that would stlll round up in the hundredth's position.
