Overview
Shared rides involve scheduling, driving routes and cost-sharing among several parties. If these are not clearly organised beforehand, disagreements often surface only just before departure. This service breaks a shared trip into three parts, namely route, timing and cost, and confirms each one, so that everyone has a consistent understanding of the trip.
During planning, the schedule is based on the actual departure point, destination and each participant's available times, and takes into account possible traffic conditions along the way so that reasonable buffer time is allowed. Cost-sharing is set out with a clear method of calculation based on factors such as driving distance, waiting time and number of participants, for everyone to review and agree to.
To use this service, please first describe the basic details of the trip, including the departure point, destination, the expected date range and the number of participants. Once planning is complete, you may share the arrangement document with the other participants so that everyone can check it again before departure.
What's Included
Gather trip information
Confirm the departure point, destination, expected date range, number of participants and each person's available times, as the basis for the subsequent planning.
Route and timing arrangements
Arrange the driving route and meeting times according to each party's time requirements, and allow reasonable buffer time for changes along the way.
Cost-sharing calculation
Set out how costs are shared based on driving distance, waiting time and number of participants, and state each assumption clearly.
Compile into a trip document
Organise the route, timing and cost arrangements into one clear document, so participants can read it and check it before departure.
Who It's For

-
Families or friends travelling together
Groups that need to coordinate the timing and costs of several people can avoid misunderstandings before departure through written arrangements.
-
First-time shared-ride users
People unfamiliar with shared-ride arrangements can use a step-by-step planning process to understand what needs to be considered.
Frequently Asked Questions
What information do I need to prepare before using this service?
Generally you will need the departure point, destination, expected date range, number of participants and each person's available times. The more complete the information, the more accurate the arrangement.
How is cost-sharing calculated?
The calculation takes into account factors such as driving distance, waiting time and number of participants, and the assumptions used are listed so that everyone can check them independently.
Can the planning results be changed before the trip?
Yes. If the conditions for departure change, you can provide the information again and the route, timing and cost arrangements will be updated to the new conditions.
Will this service arrange vehicles or drivers for me?
This service only covers organising the planning document. It does not involve arranging vehicles or drivers, and such matters are for participants to confirm themselves.
