The above graph displays the data collected from survey of bus and motorcycle users in Bangkok, with regards to the path they travel from their residence to job (or school) location. The first letter in each path represents residential zones (C = Central Business District; I = Inner Bangkok; O = Outer Bangkok and P = Surrounding Provinces). The second letter represents job zones.

From the graph, we can see that about 50% of the trips made by bus users are INTRA-ZONE trips (C-C = 1%, I-I = 35%, O-O = 7% and P-P = 8%). For motorcycle users, 55% of their trips are considered INTRA-ZONE.

The similarities of travel paths made by bus users and motorcycle users partially suggest that their trip distance does not differ significantly. However, trips by bus seems to take 40% longer than motorcycle trips, as displayed in the mean difference of the total travel time.

In order to be more accurate, the three most travel paths (1) I-I, (2) O-O and (3) I-O are investigated. The average travel time and distance are calculated for each path.
