A paired intersection time-space resource allocation method affected by a turning-to-left short lane is suitable for designing a paired intersection signal control solution without or without the turning-to-left short lane. According to a traffic flow theory and operational research, short lane length and phase-effective green-lamp time length are used as decision variables, and a fact of equal periodical time length is used as a constraint condition, thereby establishing a paired intersection time-space resource allocation module and obtaining an optimal combination among the short lane length of each intersection, the periodical time length and a green ratio. The solving algorithm of the optimization module is programmed by means of MATLAB software. By means of traffic simulation software, a coordination signal control green time difference optimization method is presented, thereby obtaining an optimal controller green time difference. Traffic flow data and VISSIM software are used for verifying the new mod
