This is a web-based survey system for collecting user preferences about improvements. It can be used to survey about any set of options, but has been tailored to be used for surveying about transportation investments and improvements.
Users are given a "budget" and asked to spend it on a set of investments and improvements. The budget provided isn't enough to cover all of the options, so users have to make choices. Users are shown the costs and benefits they have accrued as they add and remove options. In this way, the survey serves two purposes: collecting data on user preferences while at the same time educating users about the costs and benefits of investments and improvements in transit systems.
The results of the survey can be exported by an admin as a CSV file for use in comparing how different groups of transit users prioritize various improvements and investments.
The system supports multiple languages, see the data/settings.js and data/strategies.js for an example of how to set up more than one language.
