Meet ViaAlgo, the brain behind Via's 500 worldwide deployments. In our ViaAlgo Features Series, get to know her expertise, honed by delivering millions of rides all over the globe.
ViaAlgo’s Routing Engine is an auto-scheduler that successfully balances two prime goals with which agencies often struggle when delivering paratransit: increasing vehicle productivity while streamlining trips so that passengers spend less time on board and arrive on-time. Solving this problem is often the main objective for schedulers, whether working manually or assisted by software. So how does the Routing Engine help ViaAlgo do this work more efficiently? First, get up to speed on Via's paratransit solution.
Now back to the Routing Engine, which helps ViaAlgo balance productivity and on-time performance by:
After paratransit bookings are closed for the day, ViaAlgo crunches all reservation requests — from recurring trips booked weeks before to new trips booked just that day — to generate the Ride Plan, a comprehensive set of manifests for every driver shift scheduled. Wherever possible, the Routing Engine attempts to minimize vehicle deadheading and maximize time when multiple riders are aboard, in order to increase vehicle productivity. At the same time, it also tests each potential route on a map augmented with road speed and service data in order to check that pickup and drop-off times are reasonable and that riders do not spend too much time onboard.
Let’s say ViaAlgo is considering whether to add both Lisa’s and Tom’s requested trips to Joe’s manifest. The Routing Engine asks a series of questions that guide whether ViaAlgo ultimately links these trips together:
In this instance, Lisa has asked to be dropped off by 8:30 for an appointment, while Tom has been asked to be picked up between 8:00-8:30. The Routing Engine advises linking Lisa’s and Tom’s trips together so ViaAlgo can accommodate both requests and comply with the half-hour window requirements defined by the agency.
And if something changes on the day of service? A vehicle breaks down, or traffic prevents Joe from getting to Tom’s pickup within his designated window? ViaAlgo constantly optimizes behind the scenes — and offers dispatchers a number of choices for reassigning trips, from the auto- and semi-automated Reassign Assistant, to fully manual reassign features.
