Liquefied natural gas transportation network failure rate calculation method considering road section control

The invention discloses a liquefied natural gas transportation network failure rate calculation method considering road section control, and belongs to the field of dangerous goods transportation. Themethod comprises the steps of firstly, collecting and processing running track data of a vehicle, and meanwhile obtaining a transportation plan moment; secondly, determining a road failure state by taking a difference value between the planned travel time and the actual travel time as a measurement index of the failure state; thirdly, fitting the probability distribution condition of transportation failure of each road section of the urban road network by adopting a mathematical statistics method, and further calculating the transportation failure rate of the liquefied natural gas of each path of the city; and finally, calculating the overall transportation failure rate of the urban road network, and sensitively analyzing the change condition of the failure rate of the road network aftera certain road section is
