The traffic signal coordination is an important technic in intelligent transportation system (ITS) for the purposes of mobility, safety, and air quality. The environmental impacts of signal coordination are traditionally based on the analysis of vehicle emissions and noises around the roadway facilities. Less attention has been paid to in-vehicle noises. In this paper, in-vehicle noises were measured along an arterial street in Houston, Texas, United States, in which signalized intersections are equipped with traffic signal coordination. The statistically significant difference in the in-vehicle noise was tested between on the segments with and without a coordinated signal control. Results show that in-vehicle sounds under an uncoordinated control were significantly lower than under a coordinated control by approximately 3.5 dB. Hazardous exposure rate of 70 dB or above under the uncoordinated control was lower than under coordinated control. Drivers as well as passengers are mostly exposed to the in-vehicle noise during a cruise mode.
