DESCRIPTION:Professor Alejandro Tirachini\, Associate Professor of Civil 
 Engineering\, Universidad de Chile and Visiting Professor\,Technische Univ
 ersität München\, Germany\nAbstract\nA discussion of the sustainability 
 and travel behaviour impacts of ride-hailing (ridesourcing platforms such 
 as Uber\, Didi and Ola) is provided\, based on current evidence from both 
 developed and developing countries. The effects of ride-hailing on persona
 l well-being\, vehicle-kilometres travelled (VKT) and traffic externalitie
 s such as congestion are analysed. Then\, a social welfare maximisation pr
 oblem is developed\, in order to determine the optimal number of vehicles 
 and the optimal fare of a ride-hailing service. The solution is compared w
 ith the one that maximises private profit only. External costs of traffic 
 are included into the social welfare framework. The optimal solution depen
 ds on two colliding forces: (i) users waiting time\, that pushes to increa
 se driver supply and (ii) the existence of negative traffic externalities\
 , that pushes to reduce driver supply and increase fares. The problem is n
 umerically solved including scenarios with conventional and automated cars
  for peak and off-peak traffic conditions.\n \nBio\nAlejandro Tirachini (
 MSc UChile\, PhD USydney) is Associate Professor of Civil Engineering at U
 niversidad de Chile and Visiting Professor at Technische Universität Mün
 chen\, Germany. His main research interests are the planning of public tra
 nsport systems and the study of emerging mobility technologies. He has mad
 e contributions in the areas of optimal design of urban bus lines\, estima
 tion of crowding externalities in public transport in multiple cities\, mu
 ltimodal transport pricing\, bus operations and congestion modelling\, tra
 vel time variability modelling and the sustainability of ride-hailing. Apa
 rt from the research topic of this talk\, currently he is working on analy
 sing the social and traffic effects of a platform (app) for shared rides a
 nd the optimal design of automated public transport services in urban area
