SHIP IT BY GIS

A first generation, GIS (geographic information system) -based system for hazardous materials transportation routing and risk management has been developed. The system, called HAZ-TRANS, can be run using a stand alone microcomputer, and is designed to accommodate future data collection and model enhancements and can integrate generic approaches with selective customization. The network used here is one based on the U.S. Geological Survey 1;2,000,000 scale map. The network can support both national and local routing studies and accommodate other scales and formats. The principal demographic factor in the routing model is population which is basd on a GIS database available through the U.S. Census. To determine population exposure on etiher side of a transportation segment, the population database is overlaid on the transportation network. Chemical dispersion models or expert judgment can determine the appropriate minimum exposure distance for a particular shipment and material. Details of routing applications and emergency response are described.
