Abstract
In this paper, the authors analyze the influence of the introduced public transit
improvements on the exhaust emissions based on the example of the proposed
traffic organization changes i.e. separate bus lanes on Garbary and Mostowa
streets in Poznan. To that end, software for traffic microsimulation was applied
with modules enabling exhaust emission testing being divided into vehicle types,
exhaust emission standards and the extent of influence of the traffic conditions.
A selected portion of the road network of the city of Poznan was subjected to an
analysis that covered the said streets and parts of the adjacent ones. In order to
enable a comparison of the introduced changes in the traffic conditions and
exhaust emissions level, the authors analyzed the existing road network in the
first place (no separate bus lanes) and then, with the same vehicle type structure,
the variant with the said modification was scrutinized. The potential influence of
the introduced modification in the traffic organization on the traffic rate on the
analyzed road portion was determined with the use of a macrosimulation traffic
model. The above will enable a comparison of results and an assessment of the
purposefulness of the introduction of changes from an environmental point of
view. The proposed approach aims at proving the need to extend the current
approach to the planning of changes in the traffic organization and the process of
realization of infrastructural investments, particularly in the areas of intense
housing development by also taking into account the environmental aspects.
Keywords: traffic modeling, traffic microsimulation, exhaust emissions,
