The invention discloses a method for determining a lane changing form special for buses at an intersection, which belongs to the field of traffic facility design and comprises the following steps of: collecting data, and calculating the maximum queuing length of vehicles at different intersection entrance lanes and a gap between a bus and an adjacent vehicle behind the bus after lane changing; determining the minimum number of times of lane changing of the bus before the intersection, and calculating the total distance required by lane changing of the bus; a random parameter logit bus lane changing risk model utilizing mean value and variance heterogeneity is constructed, the existing intersection bus lane changing risk grade probability is determined, and the form of an intersection bus lane is determined based on the risk grade probability; a random parameter logit bus lane changing risk model using mean value and variance heterogeneity is constructed to provide a scientific basis for optimization of a lane changing form special for buses at an intersection, and the accuracy of decision-making of traffic facilities special for buses is ensured.
