# Towards Moving Objects Behavior Analysis: Region Speed Limit Rate Measure
## 3 Results and Discussion
### Second Experiment  
As a result of the two previous experiments, we chose cells 1, 6, 7, 10, and 11 for the next group of experiments. Cells 6, 7, 10, and 11 were the four cells with more trajectories, and cell 1 was the one with fewer trajectories. Then, we ran our algorithm for these five cells. For each cell, we obtained four figures to show the behavior for: (i) 28 days in the morning, (ii) 28 days in the afternoon, (iii) weekends, and (iv) weekdays. Next, we show four figures for cell 6 with _MaxSpeed_ = 50 km/h, Figures 10-13. In Appendix A, Figures 11-13, we show four figures for cell 6 with _MaxSpeed_ = 30 km/h, and four with _MaxSpeed_ = 10 km/h. In [[https://drive.google.com/drive/folders/1](https://drive.google.com/drive/folders/1) fMfJd6G1 whkFhticree-EkBWsRWbVCr8?usp=sharing]([https://drive.google.com/drive/folders/1](https://drive.google.com/drive/folders/1) fMfJd6G1 whkFhticree-EkBWsRWbVCr8?usp=sharing) (accessed on 3 December 2022) the reader can access all the figures corresponding to the five cells, with three _MaxSpeeds_ (50, 30, and 10 km/h), and for the 28 days, for the weekends, and for the weekdays. This classification by day of the week allows users to focus their analysis on specific days or groups of days, e.g., to

Considering all the results, first and second experiments, we highlight the following. On average:  
* Weekdays were slower than weekends, especially slower than Sundays in the mornings.
* Sundays were the slowest days.
* Mornings and middays (08:00 to 14:00) were slower than the afternoons (14:00 to 20:00) (although, in some cells, e.g., cell 6, the slowness was similar in both time-ranges). This makes sense since in the mornings most people commute to work and school and have lunch at noon. On the other hand, in the afternoons, not all of these people return to their morning activities. Those who do, return home at different times, e.g., in schools, classes usually start at 9:00 and end at 15:30, banks work from 8:30 to 15:00, small stores are open from 9:00 to 18:00, and big stores from 10:00 to 22:00.
* The temporal segment (08:00, 10:00) was the slowest.
* The temporal segments (22:00, 00:00) and (00:00, 02:00) were the fastest.
* There was more slowness between 08:00 and 18:00 than between 18:00 and 08:00.
* In addition:
* As _MaxSpeed_ increases, so does the speed limit rate measure in the cells; this is reasonable because as the speed limit increases, more _slow segments_ are generated, and thus, the speed limit rate measure increases as well. Note that, if _MaxSpeed_\(\rightarrow\infty\) then speed limit rate = 1, because all the segments that pass through a cell are considered slow.
* Thursday 15 August 2013 had a \"weekend behavior\" during the _Assumption of Mary_, a holiday in Portugal. Note, e.g., in cell 6, Figures 10, A1 and A5, in the morning, had similar results for Thursday 15 August 2013 and Sundays.
* Considering the five cells of experiment 2, cell 7 was the slowest.
* (00:00, 02:00), (02:00, 04:00), (20:00, 22:00), and (22:00, 00:00) were the fastest temporal segments. This is reasonable because at these hours, fewer vehicles are circulating.
* In general, the weekdays had similar behavior, although Mondays tended to be slower than the other weekdays and Tuesdays tended to be faster.
