Traffic signal lamp timing optimization method considering complex microenvironment characteristics

The invention discloses a traffic signal lamp timing optimization method considering complex microenvironment characteristics, which fully considers the requirements of environmental protection, establishes a traffic signal lamp timing model considering both traffic capacity improvement and tail gas pollution reduction, and considers the migration rule of motor vehicle tail gas emission in the atmospheric environment; herein, the influence of tail gas pollutants such as CO, HC, SO2, NOX and PM particles on atmospheric pollution is highly paid attention to, after the pollutant concentration of the pedestrian height is obtained in a numerical simulation mode, the pollutant concentration is brought into a target function of traffic signal lamp timing optimization, a traffic signal lamp timing multi-target model is constructed and is solved. According to the invention, the multi-target model proposes a target of reducing pollutant exposure of traffic participants, and the signal lamp timing multi-target model has
