Embodiment Construction
[0039] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0040] A method for evaluating the operating state of a regional high-speed road network of the present invention, the process is as follows figure 2 As shown, it is realized through the following steps:
[0041] Step 1: Divide highway network sections;
[0042] The division of sub-segments uses the highway adjacent detector as the control node, because this type of control node is a node of traffic flow change, and the traffic flow changes in each sub-segment are consistent, and it is the smallest unit for traffic state evaluation and analysis . The division of road sections takes the hub interchange where the expressway intersects as the control node, because the hub interchange is a node where the traffic flow changes greatly, and it is composed of several sub-sections in series. evaluation transition.
[0043] The present invention co...
