### Quality  
This indicator identifies the time that LUZ spaces are illegally occupied by commercial vehicles that abuse the areas, in some cases using them directly as free parking spaces. During the analysis period, several vans from nearby businesses were detected repeatedly making this improper use of the spaces. On several occasions, vehicles have even been detected parked for several days in a LUZ. As in the previous sections, these will be analysed separately. It should be specified that times exceeding the 30 min allowed are considered \(\mathrm{t_{oi}}\), with the first 30 min of the operation being reported as normal. Table 13 shows the quality factor by zone. The table shows that there is greater abuse of excess time in the afternoon sections, as well as greater abuse in Zone 4. Table 14 shows the quality factor by time section. \begin{table}

It has been observed that there is greater abuse by delivery drivers at the end of the reserved time slot, probably because they take advantage of the reserved time to find a space and park their vehicles. The quality factor per day of the week is shown in Table 15.  
Wednesdays receive the best response, while Tuesdays and Thursdays receive the worst results. To calculate OEE, the value of Non-Quality = 1 (weighted time of illegal use due to excess time) will be used. A very low indicator would denote little solidarity among transporters, who do not make an effort to comply with the established times. In this case, the result is 0.74, indicating that 26% of the time, the LUZs are illegally occupied by vans or trucks that exceed the permitted time. If we exclude operations that exceeded 30 min and focus solely on successful deliveries, there were only 305 (27.9% of those made in the LUZ), and the average delivery time was 17.9 min, which suggests to the city authorities that the 30 min currently established by the ordinance could perhaps be reduced.
