Interface lógica em ambiente SIG para bases de dados de sistemas centralizados de controle do tráfego urbano em tempo real

Abstract

The effective management of urban traffic is based on a continuous and systemic knowledge of travel behavior in the urban network. This demands a periodic effort of data collection, treatment and analysis, requiring time, financial resources and skilled staff. An efficient alternative for urban traffic management consists of implementing Urban Traffic Control (UTC) systems, which collect, model and store data relating to traffic conditions. However, these systems do not offer effective mechanisms for consulting the databases, as they are designed with an emphasis on operational traffic control. This work presents a logical interface between the dynamic database of the UTC system of the city of Fortaleza, Brazil (CTAFOR), and the Geographic Information System (GIS) platform called TransCAD. This interface combines an open modular architecture and a spatial-temporal version model to import dynamic traffic data into the static GIS platform. This interface also provides a flexible and efficient access to data collected in real time by CTAFOR, and aggregates to them a spatial character within TransCADsoftware. Therefore, this application can help to make multiple spatial analyses about the traffic behavior in the area controlled by CTAFOR. These analyses may enable the identification of non-trivial tendencies and patterns in urban traffic. This work hopes to aid specialists to use UTC systems data to assist them in the urban traffic management process, increasing the quality of the population’s daily journeys.
