  • Dec 2021
The State of Florida is one of the most populous states in the United States. Because of this increasing population, a substantial amount of freight is transported in Florida. Rail is an important mode of freight transportation in Florida. Increasing railroad transportation-based activities have led to greater economic impacts as well as more highw...

... In the present research, the Florida Priority Index Formula is employed to accurately estimate the hazard exposure of level crossings to train-vehicle collisions ( no units) based on several variables, such as daily vehicle and train volumes, train speeds, protection factors, and a parameter reflecting the history of incidents over the last five years or since the last improvement year (i.e., the year of the last upgrade). The following formula can be used to calculate the Florida Priority Index associated with level crossing ( ) [5,50,51]: ...
... More details regarding estimation of for injury hazard, fatality hazard, and property damage hazard can be found in Dulebenets et al. [51] and U.S. DOT [57]. Note that the societal costs of local level crossing events for a specific geographic area can be used by relevant stakeholders and authorities to set the hazard severity weight values. ...
... Note that the societal costs of local level crossing events for a specific geographic area can be used by relevant stakeholders and authorities to set the hazard severity weight values. The values of weights reflecting property damage hazard, injury hazard, and fatality hazard were established to be 0.01, 0.09, and 0.90, respectively, based on the previous research investigations [51]. ...
