Figure 1.
The monetary cost of public bicycle trips as a function of time.
The cost is the same in both cities.
Table 1.
One-time subscription costs in each of the 2 cities.
Figure 2.
Distribution of trip durations in Boston and Washington, D.C. clearly shows a broad spread of trips durations within the cost-free period and a more common power-law distribution for trips longer than 1 hour.
Figure 3.
Distribution of trip durations in Boston split by registered and casual users.
Casual users take longer trips on average, while the trip duration of registered users appears to drop more sharply just before 30 minutes to avoid incurring additional costs.
Figure 4.
Cumulative probability distribution of inter-station distances in Boston and Washington D.C. highlights that Boston has a much denser public bicycle network topology.
Black squares indicate mean inter-station distances.
Figure 5.
Station usage patterns show a few popular stations in Boston, yet the popularity of trips is spread out over more than two-thirds of the stations.
Figure 6.
Station usage patterns show a few popular stations in D.C., and similarly with Boston, the popularity is spread out over more than half the stations.
Figure 7.
Number of trips undertaken for unique source-destination pairs reveals a broad spread of trips.
