SIGTRANS: um sistema de informações geográficas para o planejamento viário.

Abstract

Due to the difficulties in managing viary networks, a Geografic Information System, GIS, was developed for viary planning (GIS is a system which integrates maps and descriptive information). This system helps the transportation engineer make decisions quickly and efficiently, without the manual methods that have been used. The system, called SIGTRANS, works with maps which hold ali the information that is relevant to the viary network. It generates, automatically, excellent routes for public transport according to the criteria formulated by the tranportation engineer. It also calculates points of demand using Heuristics and Operationaí Research algorithms. SIGTRANS was successfully tested using data from Novo Bodocongó III, Campina Grande's suburb in Paraíba, State of Brazil.
