Abstract: Aiming at the limitation of disperse exclusive lane locating， a two level optimization model was presented for the location of the continuous exclusive bus lane based on public transit corridor. Realistic conditions， planning and construction practice of exclusive bus lanes locations were explicitly taken into account in the proposed model. The upper-level of the proposed model was the locating model to minimize the total travel time of the whole road network， and the lower-level was the allocation model of car and bus to minimize the generalized travel cost. The genetic algorithm based on the method of successive averages was developed to solve the problem. The test of the effectiveness and practicability of the model and the sensitivity analysis of the key parameters were carried out through a case study， and the continuous exclusive bus lane locations have more superiority than discrete exclusive bus lane locations.

Key words: public transit；public transit corridor, continuous exclusive bus lane, bi-level programming model, genetic algorithm
