This paper investigates the Pareto efficiency of the various reliability-based traffic equilibria proposed in the literature and the risk-taking behavior of travelers. Reliability indexes such as the percentile travel time (PTT), travel time budget (TTB), mean excess travel time (METT) and the...

Traffic congestion and emissions are two main types of social cost, and their minimization sometimes conflicts with each other. In this paper we seek nonnegative link toll schemes and/or link toll cum rebate schemes for Pareto-efficient control and management of both vehicular congestion and...

A model is presented for analyzing Pareto-efficient build-operate-transfer toll road contracts. The formulation simultaneously allows maximizing social welfare and private profit when road users vary in their value-of-time (VOT). The failure rate and mean residual functions of the VOT...
