One of the biggest problem in most cities – noise emissions in the environment caused by transport. It is found that environment noise can cause not only discomfort, but it is also harmful to health. Therefore, noise emissions in the environment is topical environmental problem. In this article the vehicle noise emissions are evaluated, depending on traffic in Trakai city. At selected locations in the northern and southern parts of the city equivalent and maximum noise levels are measured. According to estimates of traffic day, evening and night, using CadnaA program, noise maps are simulated. The noise map will show noise emissions day, evening and night. Measurement have shown, that maximum noise values was near main roads. In the south of the city, near Gediminas street, equivalent sound level during daytime was 60 dB, evening 54 dB, night – 48 dB. In the north of the city, near Karaimai street equivalent sound lever during daytime was 59 dB, evening – 54 dB, night – 51 dB. The simulations generated sound level values were similar to measured, the differences between the simulated and measured values were up to 4 dB.
