What every single transportation app fails at is recommending a route which is technically worse, but less crowded or otherwise more preferrable.
I dont mind commute taking 10-20% longer, if I can take a seat, or trade changes undeground for changes overgrond or avoid connections with high opportunity cost, where being late cost you 30 mins wait for a next train.
- ganonm 7y agoSo if currently the recommended route is simply a function of journey time, could a map have a more sophisticated utility function that takes into account other variables like number of connections, mode of transport and pollution levels etc. Initially the weights of each variable would be unknown (100% to minimising transit time as a sane default) but over time would infer the weights by offering you a range of choices and learning from your preferred selections. One major flaw with this is that perhaps the map system relies on caching precomputed partial solutions which would be impossible if, in general, every user has slightly different preferences. I've noticed that (AFAICT) Google maps doesn't take into account individual walking speeds when calculating routes for example.

- rossmohax 7y agothat is a step in right direction, but still doesn't allow me to express my route preferences
- lozenge 7y agoGoogle has started asking me how crowded the bus is so I guess this is coming. In London you can pretty much choose a slower or cheaper route and it will be less busy. The fastest Tube lines attract more journeys.
