Dual Toll Pricing for Hazardous Materials Transport with Linear Delay
نویسندگان
چکیده
In this paper, we propose a dual toll pricing method to mitigate risk of hazardous materials (hazmat) transportation. We aim to simultaneously control both regular and hazmat vehicles to reduce the risk. In our model, we incorporate a new risk measure to consider durationpopulation-frequency of hazmat exposure. We first formulate the model as a Mathematical Program with Equilibrium Constraints (MPEC). Then we decompose the MPEC formulation into first-stage and second-stage problems. Separate methods are developed to solve each stage. A numerical example is provided and possible extensions are discussed.

Evaluating the Willingness to Pay for Urban Congestion Priced Zones (Case Study of Tehran)
Congestion pricing is one of the major travel demand management policies to reduce traffic volumes in metropolitans. One of the main factors for effective implementation of this policy is to analyze users' response to different toll rates. In this paper, the willingness of users to pay for using their personal cars is evaluated. The stated preference method was applied for data gathering. Sever...

In this paper, we propose toll-setting as an alternative policy tool to regulate the use of roads for dangerous goods shipments. We propose a mathematical formulation as well as a solution method for the hazardous materials tool problem. Based on a comparative analysis of proposed mathematical models, we show that toll policies can be more effective than the popular network design policies that...

The solutions used to solve bi-level congestion pricing problems are usually based on heuristic network optimization methods which may not be able to find the best solution for these type of problems. The application of meta-heuristic methods can be seen as viable alternative solutions but so far, it has not received enough attention by researchers in this field. Therefore, the objective of thi...

Thus, a bi-objective bi-modal optimization model for road pricing is developed aiming to enhance environmental and social sustainability by considering to minimize the air pollution and maximize the social welfare as its objectives. This m...
متن کاملRoad Pricing and Compensation for Delay
The equity issues facing congestion pricing are an impediment to its adoption. A criticism that gets very little attention is that not only does a toll road enable some to buy their way out of congestion, under certain circumstances such as a queue jumper, they do so at the expense of others that is, they may make others wait longer so that they can avoid delay, in both cases of take-away capac...
