+Fast-Trips Task 7
+=================
+
+Small Test Network - Test Demand
+--------------------------------
+
+
+Initial test demand includes trip information without associated HH or person info. As such `person_id` is
+set to zero for all trips in the trip list. One trip occurs every 10 seconds on regular intervals. Each
+trip has a random origin and a different random destination. If trips are evenly distributed the transit
+network should be able to manage this level of demand, but some buses may fill. Demand starts at 3:15 PM
+and ends at 5:15 PM. This means that there is a buffer time when transit will run without any demand at
+the beginning and end of the test period. Fields and relevant explanations are explained below.
+
+This variation also includes a arrival after / departure before preferred time.
