Stopped Delay Study

This app turns your android device into a stopped time delay computation tool. Once you launch the app you will be able to keep track of the queue length at a signalized intersection by tapping only four buttons on the screen. You simply tap a button once the light turns red and a corresponding button once a vehicle arrives, leaves the intersection, or goes by without stopping.

A summary of the results can be launched which will produce the average stopped delay experienced by vehicles and/or the average delay per cycle. A CSV file can also be generated which contains the timestamp for each vehicle arrival and departure. The CSV file also shows the number of vehicles in queue and cumulative arrival as a function of time.
