You can install the released version of cartools from CRAN with:
install.packages("cartools")
To obtain the latest updates, use RStudio and download cartools from GitHub. Run the following:
-
install.packages(“devtools”).
-
devtools::install_github(“pjossenbuggen/Basic”).
-
library(cartools)
-
zipper.simulate(5,5,53.1,5,-700,0.125,0,40,-500,14,1,1.333). To see the results, click on Merge.pdf above. A time-location trajectory (t-x) is shown.
At this point in time, cartools focuses on freeway bottleneck merging, the lose of a traffic lane from two lanes to one, and the effects of speed volatility on performance. Two merging protocols are analyzed: 1. Zipper 2. Side-by-side.
