If the separate HazMat data add-on module is installed, routing can be generated in North America, Europe and Oceania for various types of hazardous materials and dangerous goods using any PC*MILER route type.  

To generate a route for hazardous materials, select a Hazardous Materials route type in the Route Options dialog > Routing Preferences tab for the open route or create/edit a route profile to use for hazmat routing.

Hazardous material routing options for North America include: Other, Corrosive, Explosives, Flammable, Inhalants, and Radioactive. When Europe or Oceania is the selected region, the options are: Other, Explosives, Flammable, and Harmful to Water. (Additional tunnel restrictions categories in Europe – see Table 2 below). 

TIP:  The Other option should be used for any hazardous material that presents a danger during transportation and is not corrosive, explosive, flammable, inhalant, or radioactive. Common examples include: oxidizers (such as compressed oxygen tanks), combustible liquids (such as diesel fuel), and poisons (such as pesticides).

Table 1: Hazardous Material Route Options and Road Categories 

Depending on the Hazmat value you select, the routing algorithm will generate legal and safe routes by avoiding or favoring certain types of roads. The charts below describe the impact on routing based on the hazmat type.

favor = routing will prefer these segments 

no change = routing will not be altered in any way 

avoid = routing will go around these segments whenever possible 

discourage = a lesser degree of avoidance, used when a state or road authority allows hazmat only at certain times of day, with prior notification, by permit, or in limited quantities, and for tunnels not otherwise classified

For PC*MILER Worldwide and DTOD data users, the hazmat categories below are used in the Europe and Oceania regions.
