Citizens from the MMZ also suffer from accessibility disparity when it comes to their mobility options, which is related to socio-economic factors. The higher the income, the more options the citizens have for travelling within the city and to access certain opportunities. This disparity is more evident in such a vehicle-oriented urban morphology [3]. There have been different efforts and projects to improve urban accessibility within the MMZ; an example is Distrito Tec, which is a project led by the Instituto Tecnologico de Monterrey (ITESM) university in collaboration with the community in the vicinity of the campus and local authorities. It aims to improve the urban environment near the university campus for citizens and campus users. This project is one of the City Improvement Districts (CIDs) implemented in Monterrey, emerging as proposals of urban regeneration to increase citizen engagement at strategic points of the MMZ. Figure 1 shows the facilities of the ITESM Monterrey Campus, allotments and green areas within Distrito Tec. This particular CID is an area of 452 hectares located at the south of Monterrey City. It has a population of 26,333 inhabitants and comprises 24 surrounding neighbourhoods of the university [8]. Distrito Tec is of special interest to investors and local property owners due to the high demand of services (food, lodging, leisure, entertainment, among others) required by the community of students, professors and collaborators at Tecnologico de Monterrey. This dynamic environment results from the proximity and integration of this polygon to the university, and it is an interesting small-scale representation of an urban environment [9]. In response to the current increasing mobility problems in the MMZ, the present study proposes the analysis of urban accessibility using the Urban Accessibility Computer (UrMoAC) software developed by the German Aerospace Centre (DLR) [10]. The analysis was performed at two scales: (i) the metropolitan level (entire MMZ) and (ii) the local level, using the Distrito Tec Area (neighbourhoods in the vicinity of the Tecnologico de Monterrey university campus). Both scales have the objective to measure accessibility to destinations that most people frequently visit: schools, main employment centres, supermarkets and hospitals. Nevertheless, each scale of analysis has a specific scope and methodology to evaluate accessibility, as will be explained in Section 2. It is important to mention that the whole social, economic and, to a certain extent, political structure of the city behaves as a metropolitan area, despite the actual political divisions. Therefore, it is key to comprehend the urban needs at the different scales to develop public policies and interventions that respond to specific issues. In contrast to traditional urban planning theories and procedures, taking an approach from urban accessibility has been demonstrated to have an incredible potential to better understand the systemic and complex nature of cities [11]. According to [12], accessibility can be defined as the \"extent to which the land use-transport system enables (groups of) individuals or goods to reach activities or destinations by means of (combination of) transport mode(s)\". Furthermore, it has been argued that accessibility consists of four components: (I) transport, (II) land use, (III) temporal and (IV) individual [12]. Accessibility concentrates on studying and evaluating how people access, or not, the different opportunities (destinations) of the urban realm, by taking into account the distributions of activity locations and the available transport modes within a given area. It is important to mention that there are certain variables that affect the peoples' behaviour when accessing opportunities in the city, which go beyond the availability of activity locations and transport alternatives.
