This paper discusses modal division strategies adopted by cities with low levels of environmental footprint that are based on sustainable principles. Modal division, characterizes the proportion of total trips captured by each available modal transport alternative and it should be integrated in a strategic systemic vision defined by the municipality such that people s mobility and accessibility is optimized. The lack of modals has to be considered from building sidewalks and bikelanes, concerned how mature the accessibility is, to high capacity infrastructures transportation such as rapid trains or airplanes. The CO2 emissions ought to be taken into consideration so that the city is framed in the World Ranking of cleanest cities with the smallest possible environmental footprint, contributing to the sustainability of the planet. The Light Rail Vehicle, can carry between 9 000 and 30 000 passengers / hour / direction and move as trolleybus in the city with the advantages of coupling 2 to 4 cars simultaneously. The Light Rail Vehicle, also called the VLT uses electric traction and is considered 100 percent clean. This feature brings VLT to a higher position than Bus Rapid Transit - BRT modal and all bus systems that use fossil fuels as an energy source, and does not need to occupy exclusive track for its circulation. The discussion arises in the context of an urban space classified as a compact city.
