Avaliação de impactos da implantação de um corredor de faixas exclusivas em um binário – estudo de caso: trecho da av. Dom luís

Abstract

The undesirable effects of actual operational conditions of the traffic and the need for planning of large cities with its limited resources involved make it important to look for ways to improve the use of available elements. The Implementation of means that benefit the quality of operation of the transportation system and contemplate the greatest number of users becomes relevant the improvement and point the public transport as the main mode. The existence of means for further evaluation, but with greater complexity involved become an important tool for the transportation engineer. Manuals have a lot of traditional concepts and methodologies that do not contribute to observe different aspects concearning the characteristics of some impacts related to these measures. The computational evolution, the existence of theoretical microscopic models and the availability of microscopic packages capable of represent several of the variables involved in a high degree of detail, plus the large amount of replication and great amount of possible scenarios, makes microssimulation an important assessment tool with better level of the effects understanding under theses measures. In this work, it was accomplished an evaluation of the reaction of some scenarios with some exclusive lane submittted under certain distinct kinds of demand using the microscopic simulator VISSIM. It was collected data some from the literacture and some in the field for the representation of Dom Luís’ Avenue, determinig some restriction to the work made as boundary conditions. The measures of performance were useful for establishing some pattern in the results and as an attempt to explain the impacts that may be typical from the distinct scenarios. In the exclusive bus lane case, it was observed higher value over the bus speed compare to cars and a non-signifcant difference over volume with a higher standard of queues related to BRS scenario which can be explained as a increasing difficult in the right side conversion which might be reflected in the results of the ability of withdraw traffic. The BRS can be associated as a way of increase the number of bus attended by a bus stop without increase the space on the board destinated for them while deconcentrating the number of stops, reducing the time awaiting for service, bus queues and the need for lane change for undertaking indexed.
