@jensenmj will do:

1. add previous/current/next trip origin information to the view. Please also melt origin, destination, and home's latitude, longitude from six columns to two columns. Create one more column to address O/D/Home.

2. please convert some value from integers to easy-read words ("home, work, pick-up drop-off", etc). The columns need this transformation are dest_purpose, mode_1 (maybe mode_2, mode_3, mode_4 as well).

3. create ANOTHER NEW view for mapping all trip flow. please contain person ID, trip ID, trip purpose, mode_1, origin, and destination latitudes and longitudes. Just like bullet 1, please melt trip O/D into two columns.
