Embodiment 1
[0040] like figure 1 As shown, the specific steps of a method for estimating the number of road vehicles based on the travel time distribution law of the present invention include:
[0041] S1. A step of pre-establishing distribution models of different turns and travel times;
[0042] S2. A real-time estimation step of the number of online vehicles on the road section.
[0043] The specific steps of S1 include:
[0044] S11. Extract the travel time sample set T of any historical vehicle on the same day of the road section m m ,specific:
[0045] S111. Obtain the historical vehicle data of the road section m; the vehicle data of any historical week and the same day can be collected as the initial sample data; during specific implementation, a distribution model can be established for different days of the week. The historical data of a historical week and Monday is collected for simulation.
[0046]S112. Use the license plate as the primary key index to construct the iden...
