摘要：AbstractThe paper analyzes the impact of policies oriented to improve passenger public transportation and reduce emissions, on the traffic and emissions of Mexico City. Median and heavy trucks (over 3.5 tons) prohibition on the new BRT and trolleybus corridors are been implemented in Mexico City. We analyze the impact of such projects on the traffic, emissions and urban freight transportation. A macroscopic flow analysis (multimodal traffic assignment) for the estimation of flow and local emissions (NOx and CO) is used. Three scenarios area analyzed: current scenario, scenario with official prohibitions and scenario with real prohibitions. In order to compare the current scenario versus the other scenarios, a congestion index was used. The results do not show major impact on congestion index and emissions, but do on travel time for trucks. Medium and heavy trucks prohibition on arcs, belonging to the main freight transportation corridors, produces travel time increase (7%-9%) for these vehicles.
