As China's rapid economic development, the rapid increase of motor vehicles tenure, urban traffic caused by the ecological and environmental problems have become increasingly serious, greatly affecting the quality of life of urban residents and the sustainable development of cities. Ganzhou City due to the construction of transport infrastructure can hardly meet the traffic demand at the request of growth, the increase in traffic jams, traffic problems have become increasingly serious pollution, traffic brought about by air pollution has been a Ganzhou City's most important source of air pollution.
Traffic signal control system Settings in each intersection signal lights color control parameters, to signal under the control of the intersection in all directions of traffic flow in the intersection of the stalled minimum delay time, and in a number of intersection signal chain control , To seek optimal within the region, to further improve vehicle operating conditions, making pollutant emissions reduced.
Based on road intersection signal control system of transportation projects on environmental impact studies for the content of civilization will Ganzhou City Road junction of the two representative lines as a major study, based on availability, comparability, and reliability of science The principle of selecting standard carbon monoxide, nitrogen oxides emissions by an average of the main targets, running through the system before and after the target line of traffic, the delay time of the field survey, calculated and compared to the region within the motor vehicle exhaust average The number of emissions and, ultimately, traffic signal system of environmental impact.
Key words: environmental impact; traffic signal system; emissions
