STOP AND GO URBAN INTERSECTION NOISE

A summary of a procedure to predict stop and go urban intersection noise is presented. A computer program that takes into account the effects of urban building structures on multiple reflection and diffuse scattering; vehicle types, mixes, and traffic signalization on microscopic traffic flow behavior; and vehicle acceleration as well as speed and type of vehicle source strength is described. The concepts used in the acoustic model are summarized, and the principal simplifying assumptions in the numerical treatment are noted. The large number of options of street geometry caused by the presence or absence of building walls on any of the eight possible wall locations resulted in considerable program complexity, which was resolved by careful program structure and logic. A typical computer input-output is presented, and some preliminary results for a single vehicle passby are presented.
