Safest and shortest itineraries for transporting hazardous materials using split points of Voronoï spatial diagrams based on spatial modeling of vulnerable zones

:In this paper, we propose a new approach for routing and planning of hazardous materials transportation in an urban environment. The aim of this paper is to find safest and shortest itineraries for hazmat transportation. This allows us to reduce risk and to minimize damage and ultimately keeping people, property and the environment as far away as possible from the effects and consequences of hazardous materials. Indeed, we propose a calculation process based on Voronoï spatial modeling of the transportation network of hazardous materials. The development of such spatial model will make it possible to assess the proximity of vulnerable areas to risk by calculating the distance separating these spatial objects from the vehicles itineraries. The weighting of these spatial structures with socio-economic data constitutes an important spatial support for spatially analyzing the urban environment and geo-governing the transportation network of hazardous materials.
