Abstract：During the relocation of crushing stations in open-pit coal mines，the haulage routes of overburden-transport trucks （overburden trucks）and coal-transport trucks （coal trucks）may intersect，which can affect transportation efficiency and may even lead to accidents.At present，studieson intersection-scheduling technologies remain at the theoretical leveland difer fromactual mine-siteconditions.Taking therelocationof three crushing stations inthe Baorixile Open-pit Coal Mine as the engineering background，amicroscopic traffic flow model was established to adress the route-intersection problem between overburden trucks and coal trucks， describing the motion states of individual vehiclesand the overalltraic characteristics of the transportation system，with emphasis onanalyzing thecar-folowingbehavior influenced byadjacent vehicles.Onthis basis，an intersection traffc flowcontrol scheme based onintelligent traffic signals was proposed.Byanalyzing the laneorientation combinations of the intersectionandutilizingvehicle-type，speed，andother information collected by the intelligent traffic signals，atraffic-signalcontrolscheme was developed.The vehicle-passing capacityof the intersection with and without inteligent signal control was compared.The results showed that without intelligent trafficsignals，the maximum flowofoverburden trucks passng through the intersection was 74vehicles/h，which did not meet the required capacity of 112 vehicles/h and would have required increasing the number of lanes. After installing intellgent traffic signals， the maximum flow ofoverburden trucks reached 292 vehicles/h，meeting the required capacity without changing lane numbers， providing additional surplus capacity， and mitigating potential safety hazards.
