 Abstract\nMicrotransit offers opportunities to enhance urban mobility by c
 ombining the reliability of public transit and the flexibility of ride-sha
 ring. This paper optimizes the design and operations of a deviated fixed-r
 oute microtransit system that relies on reference lines but is allowed to 
 deviate in response to passenger demand. We formulate a Microtransit Netwo
 rk Design (MiND) model via two-stage stochastic optimization. The model fe
 atures a tight second-stage formulation thanks to a subpath-based represen
 tation of microtransit operations in a load-expanded network\, which optim
 izes on-demand deviations between checkpoint stops. We develop a double-de
 composition algorithm combining Benders decomposition and subpath-based co
 lumn generation armed with a tailored label-setting algorithm. Using real-
 world data from Manhattan\, results suggest that our method scales to larg
 e practical instances\, with up to 10-100 candidate lines and hundreds of 
 stops. Comparisons with transit and ride-sharing benchmarks suggest that m
 icrotransit provides win-win outcomes toward efficient mobility (high dema
 nd coverage\, low operating costs\, high level of service)\, equitable mob
 ility (broad geographic reach) and sustainable mobility (limited environme
 ntal footprint).\n\nShort bio\nAlexandre Jacquillat is an Associate Profes
 sor of Operations Research and Statistics at the MIT Sloan School of Manag
 ement. His research focuses on data-driven decision-making\, spanning inte
 ger optimization\, stochastic optimization\, and machine learning. His pri
 mary focus is on the optimization of complex transportation and logistics 
 systems to promote efficient\, reliable and sustainable mobility of people
  and goods. Alexandre is the recipient of several awards\, including the I
 NFORMS Dantzig Dissertation Award\, the Best Paper Prize from INFORMS Tran
 sportation Science and Logistics (twice)\, the Harvey Greenberg Research A
 ward from INFORMS Computing\, the Pierskalla Best Paper Award from INFORMS
  Health Applications\, and the Best Paper Award from INFORMS Data Mining a
 nd Decision Analytics. He received a Master of Science in Applied Mathemat
 ics from the Ecole Polytechnique and PhD in Engineering Systems from MIT.\
