Routing for Floating Transport
and the new challenges of A to B in our crazy cities
Previously we wrote about how we’ve begun integrating new private transport modes like scooters and cycles into our app by adding them on our ‘everything transport map’. Now, in our latest app release, we’ve added them to routing results as well, so one can compare A to Bs for all public and private options with travel times.
Routing that changes every minute
Back in the good ol days, routing was simpler. Buses and trains run on fixed networks, we would route within them, and figure out the schedules and live times. But now all the new shared modes: the cars, the cycles, the mopeds, the scooters run without fixed networks!
We have had to reinvent the rules of routing around flexible transport. Our SuperRouter technology now:
- Checks for the location of the floating infrastructure
- Calculates walking time and route to the nearest / best option
- Checks coverage area to ensure one can drop off at destination
- Calculates the best floating route to the destination, depending on mode
- And thus provides a full travel time estimate of the entire journey!
Here are 3 examples of routing with cycles, moped scooters, and kick scooters.
All the brands
Since the city and its transport change every minute, our results can also completely change every minute. We calculate them for every brand and mode available in our cities:
Comparing public and private options
Now that we have travel times, we can compare everything from public transport, walking, cabs to all floating modes. Users just search for their destination, and we do all the work.
Cities are getting crowded!
Just look at Paris to see how many different A to B options users have now:
Previously you may have been happy to take Metro 4, but now you’ve got a lot of choices. How are you going to decide?!
Let’s look at Washington DC:
Yipes. On the bright side, notice how we show you the walking time in the comparison in case you just want to pick the closest.
Ok one more… let’s look at Berlin:
Ouch. At this point your neck hurts. Es lebe die Stadt.
And that’s not all:
Multimodal+ (aka public + private transport routes)
Did we mention that our routing algorithms combine modes like trains + cabs and trains + cycles to generate additional A to B options?
We can do this with floating transport too (launching soon):
This could be the holy grail that solves the last mile problem in urban mobility! We believe such options improve access to underserved parts of the greater city.
But how do we know that the floatamajig is going to be there when you get out of the train station?
And how are we going to redesign our numerous results in order to make sense of them all?
Identity crisis
All this drama is causing some self reflection at Citymapper HQ. Are we a public transport app or a mobility app? Is our job to give you a lot of choices, or make them for you? Should we all just stay at home and watch Netflix?
Well, our mission is to give you the best choices from A to B, so that is what we’re going to do. And as cities get more complicated, we will continue to simplify them. As private transport complements and compensates for public transport, we will figure out how to give you choices that are best for you.
Ah, a transport app’s job is never done.
Float on.
