- Title
Analysis of Vehicle Holding and Cancellation Strategies in Bulk Arrival, Bulk Service Queues.

- Abstract
Bulk service queues arise in a variety of settings in transportation as a result of the need to consolidate demands for service over time. In the case of traffic lights, service is rendered in terms of the ability of a batch of cars to move through an intersection. It is often necessary to control the departure of vehicles from a queue in order to avoid sending vehicles with uneconomically small loads. Two strategies that can be used are a vehicle holding strategy, where vehicles are held until the load is sufficiently large, and a vehicle cancellation strategy, where the scheduled departure of a vehicle is cancelled if the queue is too short, in which case any customers in the queue must wait until the next departure. A separate branch of research has used purely numerical approaches for solving bulk queuing problems, as opposed to the use of classical transform techniques which all the other papers use. The article develops models for different vehicle control strategies which can be solved extremely efficiently, and hence could be used in the design of large transportation networks.
