A taxi in operation is said to be E-runtime available if it has a passenger alighting in δ x<0 minutes' time or is empty, but has no new committed taxi request to service next. In a multiagent architecture, we consider a new operation policy wherein agents of E-runtime available taxis are allowed to negotiate in individual groups of size N for new taxi requests. The main objective is to present an evaluation of the multiagent system performance gains provided by different times-to-arrival of δx, under a discrete range of demand rates for several N-group sizes, as compared with the base case when δx = 0. It is shown that the proposed policy can effectively reduce customer waiting time and empty taxi cruising time by up to about 60% and 96%, respectively, when the service demand is high for a 1000-strong taxi fleet. It is observed that the value selection for the policy parameter δx is an important aspect for improving the general performance of multiagent taxi dispatch. © 2010 IEEE.||Source Title:||IEEE Transactions on Intelligent Transportation Systems||URI:||http://scholarbank.nus.edu.sg/handle/10635/65983||ISSN:||15249050||DOI:||10.1109/TITS.2009.2033128|
