Described herein is a framework for optimal demand-based allocation. In accordance with one aspect of the framework, trip data is extracted from vehicle operation data received from one or more vehicle data devices servicing a region of interest. Vehicle demands for multiple tiles of the region of interest and mutual travel times between neighboring tiles are estimated based at least in part on the trip data. A set of candidate tiles for allocating vehicle stations may then be determined by minimizing total travel time based on the mutual travel times and vehicle demands.

Optimal demand-based allocation

A method and system to obtain taxi location data for a plurality of taxis located in a geographic region; obtain street data for a plurality of streets operating in the geographic region, the street data defining a location of the plurality of streets; store the taxi location data and the street data in an in-memory database management system; generate a rating for the plurality of streets associated with at least one currently active taxi, the rating providing an indication of a likelihood the at least one currently active taxi is available for a fare; and provide an output of the rating.
