Query: Taxi Dispatch with Real-Time Sensing Data in Metropolitan Areas: A
  Receding Horizon Control Approach   Traditional taxi systems in metropolitan areas often suffer from
inefficiencies due to uncoordinated actions as system capacity and customer
demand change. With the pervasive deployment of networked sensors in modern
vehicles, large amounts of information regarding customer demand and system
status can be collected in real time. This information provides opportunities
to perform various types of control and coordination for large-scale
intelligent transportation systems. In this paper, we present a receding
horizon control (RHC) framework to dispatch taxis, which incorporates highly
spatiotemporally correlated demand/supply models and real-time GPS location and
occupancy information. The objectives include matching spatiotemporal ratio
between demand and supply for service quality with minimum current and
anticipated future taxi idle driving distance. Extensive trace-driven analysis
with a data set containing taxi operational records in San Francisco shows that
our solution reduces the average total idle distance by 52%, and reduces the
supply demand ratio error across the city during one experimental time slot by
45%. Moreover, our RHC framework is compatible with a wide variety of
predictive models and optimization problem formulations. This compatibility
property allows us to solve robust optimization problems with corresponding
demand uncertainty models that provide disruptive event information.
