In this project, the noise measurement and analysis of the domestic ground transportation system at 30 locations have been carried out. These locations include 8 for expressway noise, 7 for freeway noise, 8 for general railway noise and 7 for mass rapid transportation system noise. Typical road structures (viaduct, bridge, trench, embankment), road pavement (rigid and soft), traffic flow and vehicle speed have been selected for noise measurement. Specially, in rail track system, the type of car body, track structure (viaduct, ground surface), track bed (ballast, slab), wheel type (rubber, steel), number of runs of scheduled trains and train speed have been taking into account for selecting measurement sites. Secondly, the traffic noise criteria and improvement countermeasures in Europe, Japan, USA and Hong-Kong have been summarized in a table for comparison. Based on the traffic noise measurement results and on foreign criteria, the drafting of noise control criteria for ground transportation systems has been completed. This draft includes the noise criteria, noise measurement procedure and the principles of traffic noise assessment. Accordingly, this draft is consistent with the Noise Control Standard for other noise sources, such as factory noise, and noise criteria in this drafting exhibits similar standard with those from other countries. Two consulting meetings have been held during the project execution period. Experts and officers from the Authorities of traffic administration, local environment protection bureaus of city and county governments have been attended and made comments, to help ensure this draft to be more sound and feasible.
