i-CHANGE is an integrated platform for managing a dockless bike sharing
system, which attempts to serve both the users’ and administrator needs in a
large variety of aspects, but also to fulfill research needs by offering valuable
insights with respect to transportation patterns.
The challenge of i-CHANGE

i-CHANGE Platform
It is built to promote sustainable
transportation by replacing the main
traditional option of private car with bicycle
and change the ownership approach and
philosophy with the approach of sharing

System Architecture
Riders can start and terminate a rent at any point inside a
large geo-fenced area.
Each bicycle has integrated in their frame a:
- GPS device
- GPRS card
- controller
Exact location of bicycle and timestamp are transmitted
periodically and stored to system servers
Stored data are enriched with data from external APIs
API for publishing the stored data for research
exploitation
Admin Dashboard
