Embodiment Construction
[0030] The algorithm of the present invention will be described in further detail below in conjunction with the accompanying drawings and examples. The following examples are implemented on the premise of the algorithm of the present invention, and detailed implementation methods and processes are given, but the protection scope of the present invention is not limited to the following examples.
[0031] In order to better understand the method proposed in this embodiment, the traffic data collection methods in this example are selected as floating vehicles and microwave detection. Because the present invention is based on state-level fusion, the traffic state in this example is 1 to represent unobstructed, 2 to represent general, and 3 to represent congestion.
[0032] refer to Figure 1 ~ Figure 3 , an adaptive traffic state estimation method, the estimation method comprising the following steps:
[0033] (1) Fusion parameter training:
[0034] The estimated traffic status...
