38. Extended cell-transmission-based evacuation planning in urban areas
A well-known traffic simulation model bases on the idea to represent street sections by so-called cells where vehicles are streaming from one cell to another in order to give a realistic image of traffic flows. Its basic ideas were picked up recently to formulate an optimization model for evacuationplanning purposes. We will address three major weaknesses of

42. Proposta metodológica para elaboração de mapas de ruído em ambiente SIG, segundo norma ISO 9613-2
Noise mapping is a new activity with growing awareness among public officials and communities. This work presents a methodological proposal for the generation of noise maps in a Geographic Information System (GIS), based on ISO 9613-2, which standards the calculus for noise attenuation during propagation outdoors. Besides the definitions of methodological pr

44. Praças de estacionamentos como estratégia para melhoria no trânsito de áreas centrais / Parking Lots as Strategy for Improving Traffic of Downtown
The traffic problems are of general scope in several cities in the world, especially in central area, usually more congested. This work aims to simulate an operational alternative that provides improved flow of vehicles in the central area. It is proposed the elimination of parking lots regulated rotary (called Blue Zone) on the streets and main avenues in t
