Embodiment Construction
[0050]Vehicle type and vehicle speed are important factors in the design of road curve alignment. Due to the particularity of the above two aspects of roads in the port area, they need to be considered in the actual design process. In the plane alignment design of road curves in the port area, three basic alignments are usually used: straight line, circular curve and transitional curve (usually a clothoid). Parameters are reasonably selected. According to the characteristics of road traffic in the port area, the present invention is designed from two aspects of linear proportion combination and linear parameter selection, and proposes a design method for the curved circle curve elements of the special road for port freight based on cellular automata. design framework such as figure 1 As shown, the main steps are:
[0051] 1. Analyze the traffic environment of the road to be designed, road grade requirements, design speed requirements, red line range, vehicle type and proporti...
