This figure illustrates differences between rural and urban cars, business day trucks, and through trucks on an example highway where each curve represents 100 percent of traffic for each vehicle category (i.e., just over 4 percent of through truck traffic per time period times 24 hours equals 100 percent)

6.3.6 Properties of Hazardous Materials Identifying every single hazardous material likely to be transported through an area is extremely difficult -- especially when the nature of the hazmat flows in the area are complex and variable. Some jurisdictions find it advisable to concentrate on general classes of materials (e.g., flammables, corrosives)

Some of these steps can be adapted as considerations for summarizing HMCFS information as follows: • Is the HMCFS information sufficient to inform and accomplish emergency prevention, preparedness, response, and recovery planning? • Is the information consistent with the HMCFS objectives?
