Hazardous materials transportation routing: Using fuzzy analytic hierarchy process based on historical traffic data

The hazardous materials (Hazmat) transportation routing is of great importance for transport safety. This paper presents a routing approach for Hazmat transportation, namely fuzzy analytic hierarchy process (fuzzy AHP) based on historical traffic data. Firstly, we use historical traffic data to preplan the candidate routes. Then we determine the best route by combining AHP with fuzzy comprehensive evaluation (FCE). Finally, we use a case to show how to plan a route for Hazmat transportation. Compared with traditional approaches, our approach can balance the safety, efficiency and cost better.
