Saturation Flow Study

Tired of computing saturation flow and startup lost times using a stopwatch? This app turns your Android powered device into a stop watch with a custom interface that allows computing saturation flow rates and startup lost times at intersections.

Features
----------------
+ Simple to use. Once you launch the app all you need to do is tap a button when each cycle starts (e.g., signal for movement turns green) and then tap the corresponding button once vehicles go through the point selected for measuring headways.

+ Report Generation. After collecting the data the user can generate a quick summary which shows the saturation flow and startup lost time or can export the data to a CSV file which contains the raw data thus allowing further analysis.

+ Easy to share. Reports can be shared with others/yourself using email or by uploading to an online storage service.

+ Vehicle flags. Headway observations for a vehicle that is not a passenge car are automatically flagged in case you want to discard them.
