Abstract: In this talk, we develop and analyze a time dependent dual toll-pricing model to mitigate the risk of hazmat transportation.Our risk measure applies time-varying link traffic flow to indicate the accident consequences. The model permits trip makers to respond differently either by choosing the least cost path or by delaying the departure time . We formulate the model as a dynamic mathematical problem and propose a solution method.

Abstract: The goal of dual toll pricing policy is to mitigate a risk of hazardous materials (hazmat) transportation via deterring hazmat traffic flow from regular traffic. This paper aims at developing a simulation model for the dual toll pricing policy under a realistic road network environment, where an extended BDI modeling framework is employed to mimic the driver’s decision making behaviors in a great detail. The proposed approach is successfully demonstrated for the traffic data of Albany, NY.
  
Title: Combined Toll Pricing and Network Design for Hazardous Materials Transportation

Abstract: Hazardous materials transport remains regulated due to its potential risk to health, safety, and environment. We investigate an application of the combination of toll pricing policy and network design and their effects on the carriers’ route choices. We present a bi-level optimization problem to minimize the associated hazmat transport risk.
  
Title: Advanced Risk Measures Applied in Hazardous Materials Routing
 Presenting Author: Iakovos Toumazis,PhD Student, University at Buffalo, 339A Bell Hall, University at Buffalo, Buffalo NY 14260, United States of America, iakovost@buffalo.edu
 Co-Author: Changhyun Kwon,Assistant Professor, University at Buffalo, 318 Bell Hall, University at Buffalo, Buffalo NY 14260, United States of America, chkwon@buffalo.edu
 
Abstract: New classes of risk measures are introduced and analyzed for local route planning in hazardous materials transportation. In particular, value-at-risk, conditional value-at-risk, and a general class of spectral risk measures are considered for risk-averse and flexible routing methods. Tractable computational methods are suggested.
