Recently a methodology for tra c networks has been developed which extracts congestion toll sets such that the tolled user equilibrium is system optimal. Properties of toll sets, such as convexity, are investigated, as well as relationships with other problems. For a given toll set, various objectives can be de ned and optimized with respect to the tolls. Examples include minimizing the total t...

We present the problem of planning mobile tours of inspectors on German motorways to enforce the payment of the toll for heavy good trucks. This is a special type of vehicle routing problem with the objective to conduct as good inspections as possible on the complete network. In addition, we developed a personalized crew rostering model, to schedule the crews of the tours. The planning of daily...

A major objective of the practical implemented cordon-based congestion pricing schemes is to maintain the traffic conditions within the cordon area, which is rarely considered in most of the existing studies. Thus, this paper addresses the optimal toll charge pattern that can restrict the total inbound flow of each cordon to a predetermined threshold. The toll charges on all the entry links of ...

The Toll-like receptor (TLR) family consists of phylogenetically conserved transmembrane proteins, which function as mediators of innate immunity for recognition of pathogen-derived ligands and subsequent cell activation via the Toll/IL-1R signal pathway. Here, we show that human TLR9 (hTLR9) expression in human immune cells correlates with responsiveness to bacterial deoxycytidylate-phosphate-...

This paper concerns tolling methodologies for traac networks which ensure that the resultant equilibrium ows are system optimal. A nonnegative vector is deened to be a valid toll vector, if the set of tolled user equilibrium solutions is a subset of the set of untolled system optimal solutions. The problem of characterizing the toll set T , which is the set of all valid toll vectors, is studied...

According to the standard model of urban traffic congestion and urban spatial structure, congestion tolling results in a more concentrated city. In recent years, a new model of rush hour urban auto congestion has been developed which incorporates trip-timing decisions — the bottleneck model. In the simplest bottleneck model, optimal congestion tolling without toll revenue redistribution has no ...

This paper proposes a self-learning approach to determine optimal pricing strategies for high-occupancy/toll lane operations. The approach learns recursively motorists’ willingness to pay by mining the loop detector data, and then specifies toll rates to maximize the freeway’s throughput while ensuring a superior travel service to the users of the toll lanes. In determination of the tolls, a mu...

Many urban areas and states are facing an increase in population density and the industrial base, creating traffic congestion and jams at toll plazas on major highways during rush hours. This article provides a detailed study and analysis of the performance evaluation of a toll plaza using discrete event simulation modeling. Under a given time-dependent traffic flow and a set of specified model...
