This repository contains analytical code developed for the FHWA sponsored project on Analysis of Travel Choices and Scenarios for Sharing Rides. Using survey data from a large Transportation Network Company (TNC) and other data sources, the project formulated various scenarios with the intention of better understanding use of higher-occupancy travel options, including ridesharing and carpooling. The scenarios incorporated research findings on the use of shared rides in the context of TNCs and also price changes for personal vehicle travel. The analytical code allows a user to understand how changes in trip cost and travel time affect shared ride choices for various market segmentations. The code is created in R Shiny and is available to users as described in this README document.

Requires:

• RStudio Deskop (Version 1.2.1335 or higher)
• Required RStudio packages: shiny, tidyverse, plotly, rsconnect, shinyBS, scales, scales, reshape2, basictabler, shinydashboard

Step 1. If not already available, download and install the RStudio development environment using the instructions available here: https://rstudio.com/products/rstudio/download/

Step 2. To install required packages, open RStudio and run "install.packages(c( "shiny"","tidyverse","plotly","rsconnect","shinyBS","scales","reshape2", "basictabler","shinydashboard"))"

• In RStudio, open the file "policy_tool.Rproj"
• In the console, enter the code: "shiny::runApp()" without the quotation marks.
• Tool will open locally, with the option to view in browser.
• All required files are included in the zipped folder. No files other than "policy_tool.Rproj" need to be opened for tool to run correctly.

Code does not require any type of build/compilation.

Test cases are automatically run as part of the build process.

Tool can be used directly in RStudio. User will be able to modify scenario details and run analysis by following the point-and-click instructions in the associated report and using the tool tips indicated by question marks in the user interface.

All required files are included in the zipped folder. No files other than "policy_tool.Rproj" need to be opened for tool to run correctly. Tool will not work correctly in Internet Explorer, but can be used in other major browsers as well as in RStudio.

The zipped folder includes the following files:

R Files:

• policy_tool.Rproj
• server.R
• ui.R

Data Files:

• elasticities.csv
• mode_share_by_city.csv
• trip_cost_by_city.csv
• vmt_share_by_segment.csv

Image Files (in www folder):

• tree_diagram.png
• question.png

All files are required for the tool to run correctly.
