Abstract: Rapid “urbanization” (more than 50% of worlds’ population now resides in cities) coupled with the natural lack of coordination in usage of common resources (ex: bikes, ambulances, taxis, traffic personnel, attractions) has a detrimental effect on a wide variety of response (ex: waiting times, response time for emergency needs) and coverage metrics (ex: predictability of traffic/security patrols) in cities of today. 

Motivated by the need to improve response and coverage metrics in urban environments, we have focussed on building intelligent agent systems that exploit past data in making sequential decisions to continuously match available supply of resources to an uncertain demand for resources.  To address the main challenges of societal scale, uncertainty and dynamism, we exploit key properties of urban environments namely homogeneity and anonymity, decomposability and abstraction of supply/demand components. In this talk, I will describe our contributions and also provide results based on real data sets (and in some cases on real systems) in transportation (taxis and bike sharing), emergency response, energy, theme parks and security.
