Abstract：Focusing on the hazardous chemical's vehicle route optimization problem (VRP), three main aspects are considered, which are 1) the path selection involving two goals, time and risk of the transpor-tation;2 ) the time and risk of transportation being time-dependent;3 ) the road ' s nodes having service time window constraints.Based on multiple objectives of transportation time and risk and above con-straints, a mathematical model for the problem is established and an ant colony algorithm to solve the prob-lem is designed.The result shows that the algorithm can effectively show the Pareto optimal path so that policymakers can make the right decision with the actual problems and decision preference.At the same time, transportation enterprises can formulate vehicle departure timetable according to the result in differ-ent departure time while regulators can adjust the path ' s transportation time and risk through planning node' s service time window and allowing a stopover in the node.
