Alex Wallar

+

+ A city's streets are full of wasted motion — cars carrying one person, buses + no one is riding, people waiting for both. I build the optimization that + claws it back: pooling trips into shared rides, predicting demand before it + shows up, and moving vehicles to meet it. These days that's robo-taxis + at Zoox. Before that, I co-founded + The Routing Company out of MIT CSAIL and spent seven years + as its CTO, putting on-demand public transit on the ground on three + continents. +

Co-founder & CTO · The Routing Company

+

+ MIT spinout building demand-responsive transit — routing algorithms that + let public agencies run service where riders actually are, instead of + fixed routes past empty stops. Built the engine behind the Pingo platform + and deployed it on three continents: Houston, Kitsap County, and a + 132-vehicle network in Rochester, NY — among the largest on-demand transit + services in North America — plus the Scottish Borders, Dunoon, and + suburban Melbourne.

02Research

+
+
+

+ My research asks how much a city can move with how few vehicles. The headline + answer, from the PNAS study I co-authored at MIT: 3,000 shared vehicles could + serve 98% of New York's taxi demand — a result covered by CNN and Forbes. + Since then it's been predictive routing, vehicle rebalancing, and + high-capacity ridepooling for robo-taxis, with earlier detours into + UAV motion planning, acoustic sensor networks, and in-browser eye tracking. + 2,400+ citations. +
