Before
10000 users.
Explanation: In Hangzhou, Hellobike has about 9 million 650 thousand users (2019 data). There are also many users in Nanning. Based on machine-learning techniques, Hellobike will identify 6,000 users for treatment in Hangzhou and 4000 users in Nanning. These users have a history of parking outside the designated areas and are likely to do so again on future trips. The investigators will randomize these 6,000 users into the control and treatment groups T1-T6.

Intervention (Hidden)

Before
T1 Control:
App message: None
T2 Reminder
App message: “Areas XX* are already crowded. Please park the bicycle in a surrounding area.”:
* Based on historical patterns, Hellobike’s algorithm will identify the user’s likely destinations and the text in the message will mention the crowded area’s among the user’s expected destinatons.
T3 Reciprocity
App message: Areas XX are already crowded. Please park the bicycle in a surrounding area.
The proper parking of the last user made it convenient for you to find the bike, please provide the same service to the next user!
T4 Specific reciprocity
App message: Areas XX are already crowded. Please park the bicycle in a surrounding area.
The proper parking of the last user made it convenient for you to find the bike, please provide the same service to the next user!
Users in T4 will receive the following message by phone SMS in the weekend of the week when they are included in the experiment.
HB users can help each other through orderly parking! Shared bicycles that are parked in non-crowded areas are reused by another user on average 15 to 40 minutes sooner than bicycles parked in crowded areas! Thank you for proper parking!
T5 Circularity
App message: Areas XX are already crowded. Please park the bicycle in a surrounding area.
You could easily find a bicycle because previous users made it convenient to find bikes. Please do not break the chain!
T6 Specific circularity
App message: Areas XX are already crowded. Please park the bicycle in a surrounding area.
You could easily find a bicycle because previous users made it convenient to find bikes. Please do not break the chain!
After their first trip in the experimental period, users in T6 receive the following message by phone SMS:
HB users operate and enjoy the bike-sharing service together! Shared bicycles that are parked in non-crowded areas are reused by another user on average 15 to 40 minutes sooner than bicycles parked in crowded areas! Thank you for proper parking!
