Key Terms home station X station Y office 1 trip purpose: going to work 3 subtrips means of transportation: bicycle, train, walk 07:24-07:35 1.8km 07:40-08:20 20.1km 08:20-08:30 0.4km 07:35-07:40 

Persontrip Dataset questionnaires by Tokyo Metropolitan Area Transportation Planning Council date of query: October 1st, 2008 contains information about 587,340 individuals synthesized to 1-minute positions by the University of Tokyo Center for Spatial Information Science (CSIS) 845,769,600 point positions in total (24 hours * 60 minutes per individual) PostgreSQL & PostGIS database, total size: 630GB 

What does the data tell us? 112,286 people in total used their bikes during the sample period (24 hours), that equals 19.1% of the total sample population of 587.334 people. They got on their bikes 272,897 times in total, 2.4 times each in average. Overall they used bicycles for 478,738km - that is further than the distance from the earth to the moon! The average distance was 4.2km per person, 1.7km per subtrip. The longest subtrip was 144km. 

Finding #1 Cycling is not really popular among the sample population. 

Finding #2 Bicycles are mostly used by young boys (6-20 years old), middle-aged to elderly women (31-70 years old, especially 36-65 years old) and elderly men (over 70 years old). 

Comparison of Occupation Class Distributions (%) 

Finding #3 Bicycles are mainly used by white-collar workers (46.4%) and students (22.6%), not so much by blue-collar workers (5%) and unemployed (9.2%). 

Bicycle Subtrips by Gender Over Time 

Bicycle Subtrips by Age Over Time (%) 

Finding #4 Bicycles users vary during the day: mostly male and young (6-25 years old) in the morning and evening, mostly female and older (over 60 years old) during the day. 

Bicycle Subtrips by Purpose Over Time 

Finding #5 In the morning bicycles are mostly used to get to work or school, in the afternoon and evening to get back home. During the day they are used for shopping (early noon) and for running errands (morning and afternoon). 

The Morning Rush Hour Period Defined from 6:00am to 9:59am. 68,029 people in total used their bikes during the morning rush hour period (4 hours), that equals 60.6% of the total cyclist population of 112,286 people. They got on their bikes 74,649 times in total, 1.1 times each in average. Overall they used bicycles for 154,279km. The average distance was 2.3km per person, 2.1km per subtrip (compared to average distances of 4.2km per person and 1.7km subtrip for all cyclists).

Finding #6 Trips by bicycle during the morning rush hour go mostly (63%) all the way from home to the final destination. When integrated into a multi-modal trip, bicycles are mostly used on the “home”-end of the trip.

Finding #7 The usage of bicycles during the morning commute differs by greatly by location, depending on socio-demographic factors, urban structural function, special infrastructures. 

Findings Summary Cycling is not really popular among the sample population. Cyclists are mainly between 16 and 25, not so much people over 70 years old. Young boys (6-20 years old), middle-aged to elderly women (31-70 years old) and elderly men (over 70 years old) dominate their age groups. Bicycles are mainly used by white-collar workers and students. Young male cyclists in the morning and evening, elderly female during the day. 

Findings Summary (cont’) In the morning bicycles are mostly used to get to work or school, in the afternoon and evening to get back home, during the day for shopping and for running errands. Most bicycle trips are under 2km, but some cover longer distances (>10km). Trips by bicycle during the morning rush hour go mostly to the final destination. When integrated into a multi-modal trip, bicycles are mostly used on the “home”-end of the trip and are mostly followed by train rides. The usage of bicycles during the morning commute differs by greatly by location.
