Aspects also include transmitting the request for the ride share to the candidates, the request indicating an estimated impact on a current trip of the candidates. Aspects also include receiving one or more positive responses to the request, the responses indicating a desired fare contributions for the ride share and determining a match from the one or more positive responses.
