cartools: Tools for understanding highway performance.

Installation

You can install the released version of cartools from CRAN with:

install.packages("cartools")

Recommendation

To obtain the latest updates, use RStudio and download cartools from GitHub. Run the following:

1. install.packages(“devtools”).

2. devtools::install_github(“pjossenbuggen/Basic”).

3. library(cartools)

4. 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.

State of development

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.
