【摘要】：露天礦傳統(tǒng)車流規(guī)劃以路徑最短為基礎,沒有考慮路段通過能力和路段擁擠程度,車流規(guī)劃結果存在超過路段通過能力的隱患。為了解決這一問題,以Wardrop均衡原理為理論依據(jù),綜合考慮路段車流、路段通過能力的影響,引入綜合路阻理念,建立了露天礦車流路網(wǎng)均衡分配模型,實現(xiàn)了在傳統(tǒng)車流規(guī)劃結果基礎上對路段車流進行再次優(yōu)化。實驗結果表明,路網(wǎng)均衡分配模型在不考慮路段綜合路阻時,其分配結果與傳統(tǒng)車流規(guī)劃一致;當考慮綜合路阻時,各路段的車流行駛總時間最小,有效避免了路段擁堵,實現(xiàn)了對卡車調度進一步優(yōu)化,證明本模型具有更強的通用性和實用性。
[Abstract]:The traditional train flow planning of open-pit mine is based on the shortest path without considering the passage capacity and congestion degree of the road section. The result of the train flow planning has hidden trouble of exceeding the passage capacity of the road section. In order to solve this problem, based on the theory of Wardrop equilibrium principle, considering the influence of traffic flow and capacity of road section, the paper introduces the idea of comprehensive road resistance, and establishes the equilibrium distribution model of vehicle flow network in open-pit mine. Based on the results of traditional vehicle flow planning, the traffic flow of road section is optimized again. The experimental results show that the allocation results of road network equilibrium allocation model are consistent with the traditional traffic flow planning without taking into account the road sections' comprehensive road resistance, and when the road resistance is considered, the total travel time of each section is the least, which effectively avoids the congestion of the road sections. The further optimization of truck dispatching is realized, and it is proved that this model is more universal and practical.
