However it does not support door-todoortransportation and might be inconvenient due to limited services in offpeakhours or high costs when travelling long distances. A solution growing inpopularity is ride sharing, a form of CT making alternative transportation moreaffordable.

WEticket supports sharing traintickets through finding additional people going onto the same journey.    «
