      abstract = {Hazardous material (hazmat) transportation has been an  important issue for handling hazardous materials, such as  gases and chemical liquids. In the past, researchers have  made great efforts to develop policies and route planning  methods for hazmat transportation problems. In 2014,  Kaohsiung City in Taiwan suffered a gas pipeline explosion  at midnight; 32 people were killed, and hundreds of people  were injured. After the incident, policies and routing  strategies for hazardous materials (hazmat) transportation  in Kaohsiung were initiated to avoid pipeline  transportation. Although methodologies for hazmat  transportation have been proposed and implemented to  minimize potential risks, multiple objectives need to be  considered in the process to facilitate hazmat  transportation in Taiwan. In order to consider both  government and operators’ aspects, a multi-objective  formulation for the hazmat problem is proposed and a  compromise programming method is applied to solve the  problem with two objectives: travel cost and risk. The path  risk is defined based on risk assessment indexes, such as  road characteristics, population distribution, link length,  hazardous material characteristics, and accident rates. An  aggregate risk indicator is proposed for roadway segments.  The compromise programming approach is developed from the  concept of compromise decision and the main idea is to  search the compromise solution closest to the ideal  solution. The proposed method is applied to Kaohsiung City,  Taiwan. The results show that two conflicting objectives  keep making trade-offs between each other until they  finally reach a compromise solution.},
