Environmental Policy Aid Under Uncertainty

Citizens' juries: an aid to environmental valuation?

Survey techniques such as contingent valuation have been used extensively by environmental economists to develop an understanding of consumer preferences for environmental goods. On the basis of such techniques, recommendations have been formulated in relation to environmental policy. However, the exposure of weaknesses in this method has led economists to look to other informationgathering app...

Transit Signal Priority: Proposing a Novel Algorithm to Decrease Delay and Environmental Impacts in BRT Route Intersections

Intersections are considered as the most critical parts of the bus rapid transit (BRT) system. Transit signal priority is one of the efficient solutions to reduce BRT fleet delays at intersections. The aim of this study is to propose a new algorithm to decrease the BRT fleet delays at actuated intersections, while reducing the negative impacts on different approaches. The adaptive strategy is a...

A Finite Capacity Priority Queue with Discouragement

In this paper we report on a study of a two level preemptive priority queue with balking and reneging for lower priority level. The inter-arrival and the service times for both levels follow exponential distribution. We use a finite difference equation approach for solving the balance equations of the governing queuing model whose states are described by functions of one independent variable. H...
