Embodiment 1

[0089] Such as figure 1 As shown, it is a flow chart of a specific embodiment of a method for guiding and optimizing a new river-crossing channel based on the BMO algorithm of the present invention. see figure 1 , the specific steps of this specific embodiment include:

[0090] Step 1: Select the layout range, and select the layout starting point within the buffer zone of the layout range. Centering on the new river-crossing channel, according to its road grade and traffic attraction, specify a certain layout radius r to form a buffer zone with a width of l, and consider traffic flow, important road nodes, and important city entrances and exits in the buffer zone. Specify multiple nodes with different orientations as starting points. Define the layout start set as {v p},Such as figure 2 shown.

[0091] Step 2: Establish a cost-optimized guidance optimization mathematical model for the new tunnel scenario. First, the improved arc-node data model is used to represent the...

Abstract

The present invention relates to a kind of BMO algorithm-based guiding optimization method for newly-built river-crossing channels, comprising the following steps: S1. Selecting the layout range, and selecting the starting point of layout in the buffer zone of the layout range; S2. A guiding optimization mathematical model with optimal cost; S3. Solving the above mathematical model by using the BMO algorithm; S4. Obtaining a guiding optimization scheme.

Description

technical field [0001] The invention relates to the field of road traffic planning, and more specifically, relates to a BMO algorithm-based guidance optimization method for newly-built river crossing channels. Background technique [0002] With the expansion of city scale, the obstruction of rivers inside the city has become the bottleneck of urban traffic. The new river-crossing channel is conducive to relieving the traffic pressure across the river, building an integrated urban structure, and enhancing the coordination of urban development. As a traffic static guidance facility, the guide signs must be closely integrated with the road network update, and the guide sign system replacement speed is much lower than the road network construction speed. After the new river-crossing channel is built, it will be time-consuming to replace all the guide signs in the entire area. Power-consuming and not in line with reality. Therefore, how to scientifically optimize the guidance o...
