The three operators each have a different definition of their service area, with Callabike limited to the central downtown area, oBike allowing usage within the city limits and MVG Rad’s coverage somewhere in the middle. Some row patterns are visible in the oBike points, likely from their initial deployment along a road.
Having a larger service area does mean less competition in the outer boroughs however; one would expect the demand to be much lower as well. Additionally the larger area complicates service and maintenance.
Calculating movements from the mined data is much more error prone than estimating the total number of bikes as noise has a greater impact on the data quality. However by applying the same noise reduction techniques on all data sets, a rough relative comparison of the bike sharing operators should be possible. The duration is recorded in discrete 5min intervals while distance is the great-circle distance between rental and return location. The speed is based on these distance and duration measures.
As the location data has some noise in it even when the bike is stationary, only trips that are more than 400m and have an average speed of at least 1km/h per hour are taken into account. Any trips with an speed of over 25km/h are disregarded as they likely are drives on relocation/maintenance trucks or noise.
While the trip profile in regard to distance and speed is rather similar for all operators, oBike as the new entrant shows a much lower number of movements per hour. The somewhat lower distances and higher variation in durations might be explained with some people trying out the service on shorter test distances.
To get an estimate of estimate of network utilization the total number of movements in a day was divided by the average total number of each operator’s availiable bikes on that day. Here MVG Rad shines with their utilization reaching 200% on some days (an average 2 trips per bike) with a mean of 121%. The combination of significantly more bikes and lower usage in general shows in the utilization of oBike, reaching an mean utilization of just 4% with a max of 9%
The different strategies regarding service areas are visible in the movement data and mostly as expected. Interestingly the movement patterns of oBike are more similar to Callabike - a high demand downtown area with some outliers added - than to MVG Rad.
The pattern of MVG Rad might be explained with their optional offering of bike rental stations at subway stations and discounts for subway pass holders. Customers could take the subway and complete the last mile on a rental bike leading to a more spaced driving pattern than more leisure oriented downtown / Englischer Garten routes.
Looking at the movements over time shows a mostly similar behavior for all operators with a small morning peak, large evening peak and few rides during the night. Open the chart in a new tab to see details.
The initial estimations show that even with generous incentives for new customers (first 3 rides free; one full free day due to public transport strikes) and a significantly larger number of bikes it still has a long road ahead. As it is still early in the development the short observation time frame is not enough to estimate the impact of oBike on the Munich bike sharing market. However the for now very low utilization rates pose the question whether the city space is used efficiently.
