This app turns your android device into a stopped 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.
Features
----------------------------
+ Simplicity. Tap a button once the light turns red and another button once a vehicle arrives, leaves the intersection, or goes by without stopping.
+ Delay per vehicle. The report produced contains the average stopped delay experienced by vehicles.
+ Delay per cycle. If more than once cycle is collected then the average delay per cycle is computed.
+ Simple export. A report in CSV file contains a timestamp for each vehicle arrival and departure.
+ Queue analysis. The CSV report contains the cumulative number of vehicles for each timestamp.
