Based on the assumption and the analysis of the practical situation, a model of calculating the efficiency of the lane at the intersection upstream, which imitates the work theory in physics, is given. This model is a tool which can be used to evaluate the signalized intersection upstream traffic flow quantificationally and intuitively. According to the model, it also gives a method to set the bus stop at the intersection upstream by the analysis of the relation between the length from the bus stop to the stop line and the efficiency of the lane at the signalized intersection upstream influenced by the bus stop. The result shows that this model can calculate the efficiency and gives a better location of the bus stop.
