Shared TransfersConceptual overview:<ul><li>The Shared Service is a bus service from LeChable to Verbier (about 10mins drive) that can be shared by multiple passengers allowing people to complete their journey without hiring an expensive taxi<ul><li>&nbsp;It is a bus with up to 13 seats. &nbsp;</li><li>LeChable is where the train arrives, at the bottom of the mountain. Verbier is the mountain village where the skiers stay. &nbsp;&nbsp;<ul><li>Uphill (arrivals, at start of holiday): &nbsp;LeChable→ Verbier&nbsp;</li><li>Downhill (departures, at end of holiday): Verbier → &nbsp;LeChable</li></ul></li></ul></li><li>There is a Shuttle (ie a bus available) for every train that starts/ends at LeChable that goes to/from GVA. &nbsp;Typical tourist from, say London….<ul><li>Arrival: &nbsp;&nbsp;<ul><li>Flight: London→ GVA</li><li>Train: &nbsp;GVA→ LeChable</li><li>Shuttle bus: &nbsp;LeChable→Verbier &nbsp;(uphill)</li></ul></li><li>Departure: &nbsp;&nbsp;<ul><li>Shuttle bus: &nbsp;Verbier→LeChable (downhill)</li><li>Train: LeChable → GVA</li><li>Flight: GVA→ London</li></ul></li><li>Therefore<ul><li>The uphill shuttle (LC→V) is derived from the fight arrivals and then matched train GVA→LC (working forward from the flight arrival time)</li><li>The downhill shuttle (V→LC) is derived from the fight departures and then matched train LC→GVA (working backwards from the flight departure time)</li></ul></li></ul></li><li>Each passenger is assigned to their best shuttle according to their flight details. &nbsp;See flight_trip index - which assigns them to the best train time.</li><li>Let's first assume infinite capacity for the Shuttle and then consider how to limit the seats.</li></ul>Assigning Transfers to a Shuttle Bus&nbsp;<ul><li>A “Shared” Transfer (in a booking) needs to be assigned to a shuttle&nbsp;</li><li>This is important as there are limited seats and the shuttle driver needs to know who they are picking up and where they are taking them to</li><li>Also, I want to be able to see the list of shuttles and how many seats are booked (and free = 13 - # booked), as during the day as flights are late/early people may need to be bumped to earlier/later shuttles. &nbsp; This should only applies to the Arrivals (Uphill) shuttles as &nbsp;people will take their chosen Shuttle on the Departures (downhill) in time to catch their planes (ie we are ‘upstream’ of any flight delays). &nbsp;But we should be able to bump people up down the shuttles schedule easily/quickly and indeed enable the user to do that themselves (we should send them an email/whatsapp when we think they are on their train and confirm etc).&nbsp;</li></ul>Pricing<ul><li>There is also the pricing of Shared to consider</li></ul>
