The invention relates to the technical field of urban road traffic signal control, and particularly discloses a signalized intersection lane green light loss time calculation method, which comprises the steps of generating release state information of a lane according to a corresponding relationship between intersection signal lamps and the lane; receiving release state information of each entrance lane, and sending the release state information to the data analysis unit in real time; detecting traffic flow operation information on an entrance lane of the current intersection in real time, andsending the traffic flow operation information to a data analysis unit; and calculating corresponding green light loss time in different traffic scenes by the data analysis unit according to the release state information and the traffic flow operation information of each entrance lane, and sending the green light loss time to the traffic signal control machine. The invention further discloses a system for calculating the green light loss time of the signal intersection lane. The signalized intersection lane green light loss time calculation method provided by the invention can accurately obtain the signalized intersection green light loss time, thereby providing data support for scientific evaluation of signalized intersection control benefits.
