## 3 Analysis and Results
### Distrito Tec Area  
Figure 10 shows the average time by AGEB to access the five closest public kindergartens. As most children going to kindergartens are not able to cycle, the accessibility measure was computed for travelling by foot. Even though the number of kindergartens within the polygon is low (four), the surrounding areas at the north, west, and southwest have considerably high densities. In contrast, the areas in the east and the southeast have very low densities. Three of the eleven AGEBs within Distrito Tec meet the constraint to access the closest five kindergartens in a maximum of 15 min, with all three AGEBs in the 11-15 min class. The rest of the AGEBs have considerably higher access times with four AGEBs in the 16-20 min class, three in the 21-25 min class, and one in the 26-30 min class. The lowest accessibility levels are represented in the AGEBs located to the southeast of the polygon. This is due to the relatively low density of destinations in the surrounding areas, especially to the east. As most AGEBs within the polygon do not meet the 15 min travel time criteria, it can be argued that in terms of access to kindergartens by foot, the Distrito Tec Area cannot be considered a 15 minutes city. Nevertheless, additional information should be collected to know how many children in the Distrito Tec Area are within the age range to go to kindergartens. In the case that this number is low, the computation could be made to the closest kindergarten, as this one could host all the local demand. Such a scenario would considerably increase the levels of accessibility. Figure 11 presents the average time by AGEB to access the five closest public primary schools by foot. Again, the density of destinations within the Distrito Tec Area is low, with only three schools. Yet, the surrounding areas at the north, northeast, west, and southwest have considerably high densities. Only three out of eleven AGEBs from the Distrito Tec Area meet travel times of a less than or equal to 15 min. These AGEBs are located on two opposite corners of the polygon (northeast and southwest) and can meet the 15 min parameters due to the high number of destinations in the outer nearby areas. In contrast, six AGEBs require a travel time of 16-20 min to reach the closest five destinations. The higher travel time is due to the low number of destinations in central areas of the Distrito Tec Area. Finally, two AGEBs reach the 21-25 min class. Given the previous results, it can be said that in terms of access to public primary schools, the Distrito Tec does not meet the requirements to be considered a 15 minutes city using only foot as the travel mode. However, by using other modes of transporta

As the age groups that attend secondary and high schools usually are able to use bicycles as their main travel mode, the following computations were performed considering bicycle as the transport mode. It is important to bear in mind that the average speed of a person travelling by bike is three-times higher than travelling by foot. Therefore, a much higher number of destinations can be accessed within the same time. Figure 12 presents the average travel time by AGEB to reach the five closest public secondary schools travelling by bike. Even though the density of destinations in the Distrito Tec Area is extremely low (two) and remains low in the outer areas, the accessibility levels are rather high. All AGEBs can access the closest five destinations in a maximum of 10 min of travel time. From the 11 AGEBs, two are in the lowest class of only 0-5 min of travel time. These AGEBs are located at the southwest border of the polygon, where the only two destinations inside the polygon are located and there are three others in the vicinity.
