AbstractThis study presents a comparative traffic noise study done between signals and roundabouts in Doha, Qatar. Traffic noise and volume data were collected at four signals (two 2-lane and two 3-lane) and four roundabouts (two 2-lane and two 3-lane) for daytime hours during weekday and weekend. In general, the mean daytime noise levels exceeded the local (55 dB(A)) and the WHO's (65 dB(A)) allowable thresholds. Based on the before-and-after noise study conducted at one of the roundabouts being converted to a signal, the noise at the signal was 3.5 dB(A) more. Results of noise level comparisons between the eight intersections suggest that 3-lane signals are noisier than 2-lane signals, 2-lane roundabouts are noisier than 3-lane roundabouts, 3-lane signals are noisier than 3-lane roundabouts, and 2-lane roundabouts are noisier than 2-lane signals. Finally, traffic noise prediction models were developed based on the data collected.
