On this Picostat.com statistics page, you will find information about the RailTrail data set which pertains to Volume of Users of a Rail Trail. The RailTrail data set is found in the mosaicData R package. You can load the RailTrail data set in R by issuing the following command at the console data("RailTrail"). This will load the data into a variable called RailTrail. If R says the RailTrail data set is not found, you can try installing the package by issuing this command install.packages("mosaicData") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the RailTrail R data set. The size of this file is about 4,032 bytes.
Volume of Users of a Rail Trail
The Pioneer Valley Planning Commission (PVPC) collected data north of Chestnut Street in
Florence, MA for ninety days from April 5, 2005 to November 15, 2005. Data collectors set up a
laser sensor, with breaks in the laser beam recording when a rail-trail user passed the
data collection station.
A data frame with 90 observations on the following variables.
hightemp daily high temperature (in degrees Fahrenheit)
lowtemp daily low temperature (in degrees Fahrenheit)
avgtemp average of daily low and daily high temperature (in degrees Fahrenheit)
spring indicator of whether the season was Spring
summer indicator of whether the season was Summer
fall indicator of whether the season was Fall
cloudcover measure of cloud cover (in oktas)
precip measure of precipitation (in inches)
volume estimated number of trail users that day (number of breaks recorded)
weekday indicator of whether the day was a non-holiday weekday
There is a potential for error when two users trigger the infrared beam at exactly the same time since the counter
would only logs one of the crossings. The collectors left the motion detector out during the winter, but because the
counter drops data when the temperature falls below 14 degrees Fahrenheit, there is no data for the cold winter months.
