摘      要：In order to improve the performance of the signalized intersection,an unconventional scheme tandem design(TD)is proposed.A simulation experiment is conducted to evaluate the capacity and delay under the unconventional scheme and two conventional lane assignment ***,the VISSIM is employed as microsimulation to obtain the delay of different designs at signalized T-intersections under different conditions of traffic flow and turning ***,a method based on discriminant analysis(DA)is proposed to determine the best design scheme using the flow and turning proportion as ***,a case study in Changsha city,China is used to demonstrate the efficiency and accuracy of these *** results indicate that the traffic flow and turning proportion are the crucial factors in scheme selection of lane *** from the previous research,the TD has better performance over various traffic flow ***,a proper proportion of left turns makes TD an outstanding option,which can reduce the delay and decrease the average number of stops and queue length ***,the proportion should not be too high or too *** research results can help practitioners obtain a quantitative view of appropriate design schemes at signalized intersections when trying to relieve traffic congestion according to different traffic conditions.
