COOPGO Carpool Service

COOPGO Carpool Service is a carpool management microservice. It is part of the COOPGO Technical Platform and the base carpool component of COOPGO's RIDYGO application. It was redesigned from scratch to implement natively the new OCSS carpool standard and bring interoperability.

This is not a full featured carpooling application. There is no UI and it only implements basic carpooling functionalities (create and find, book journeys). The objective of this service is to be embedded in a bigger carpool or Mobility as a Service platform.

It provides a gRPC service to interact with other microservices, and an HTTP API to provide interoperability with external carpooling operators.

Technical architecture

Managing trips and journeys

Trips and journeys are managed through the provided gRPC service and stored in the database (MongoDB for the moment). They are stored in the database as GeoJSON feature collections with extra members defining the trips and journeys non-geographical parameters.

Tiles architecture and cache

To reduce dependencies on the chosen database, we decided to manage geographical calculations directly in out code instead of relying completely on MongoDB geographical features.

OCSS standard

The OCSS standard is the new carpooling interoperability standard defined by the french carpooling ecosystem.

COOPGO Carpool Service implements all of this standard, except the messages endpoint which we think should be handled outside of this service, as different carpooling or MaaS applications may handle messaging differently.
