Non-motorized transportation (NMT) has emerged as a mitigating alternative for the negative externalities of motorized travel. This research presents an overview of the intra-metropolitan geography of transportation mode choice in the journey to work in the México City Metropolitan Area (MCMA), which can be seen as a representation of the huge socioeconomic inequalities typical of the Global South. The regression model applied showed that, as expected, socioeconomic variables were strong determinants of mode choice. An increase in age, as well as lower categories of socioeconomic class and educational attainment, were associated with the use of transit and non-motorized travel. Other factors positively associated with bike use were distance to the center, density of mass-transit systems stations, street intersection density, and the flat surface. The pattern of walk commuting with respect to the city center followed a u-shaped curve, while factors significantly positively associated were female, population density, the jobs-housing ratio at the origin, and the density of mass-transit systems stations. The paper concludes with a discussion of the research implications to leverage public policy efforts to promote NMT.

非机动运输（NMT）已成为缓解机动旅行负面外部影响的替代方案。这项研究概述了在墨西哥城大都市区（MCMA）上班途中大都市内部的交通方式选择地理，这可以看作是典型的全球南方巨大的社会经济不平等现象的代表。所应用的回归模型表明，正如预期的那样，社会经济变量是模式选择的重要决定因素。年龄的增加以及社会经济阶层和教育程度的降低归因于过境和非机动旅行的使用。与骑车使用有正相关的其他因素是：到中心的距离，公交系统站点的密度，街道交叉路口的密度和平坦的表面。相对于市中心的步行通勤模式呈u形曲线，而与女性，人口密度，起点的工作住房比率和大众运输系统站点的密度呈显着正相关的因素。本文最后讨论了利用公共政策努力促进NMT的研究意义。
