Impacts of Modifications on Urban Road Infrastructure and Traffic Management: A Case Study

This paper presents the impacts that modifications on urban road infrastructure and traffic management measures could have on traffic and emissions of a zone. A new toll highway, the change of flow direction of two arterial roads and a new set of bridges in a zone within Mexico City are analyzed. Results indicate that the first two options have small benefit on the short term, but it soon disappears due to induced traffic, and last option has a negligible effect. Hence, there are not suitable actions, on the supply side, for reducing traffic and emissions for the near-future.
