L2 is also a location with high traffic volume, but it is adjacent to a residential area. For these reasons, the rush hour trend (Figure 3) is similar to that observed for L1 (the trend is reversed between morning and afternoon). However, since B2.2 is already in a residential area, it shows much less traffic than the other two and the inversion is not evident in this case, suggesting that it is mainly residents who use this route. Interestingly, there is a very large difference between the counts going north on B2.3 and B2.1 (587 -> 316 in the morning and 998 -> 281 in the afternoon), indicating that most cars are turning west at this intersection. The same applies to the counts going south, which are much higher on B2.3 than on B2.1, suggesting that some of these cars may be coming from the west.
The residential area (L3) also shows the same rush hour inversion for most of the barriers (Figure 4). However, this effect is not so evident as in the first two locations, probably for the same reasons mentioned above (heterogeneous intersection types and camera angles). In these areas, especially during rush hours, people tend to try different (and unexpected) routes to avoid congestion, most likely using different options in the morning and afternoon. Despite the higher complexity of this location, there are some observations that are consistent with expected behaviour, such as B3.3 in the morning shows much more traffic going south (away from the residential area), and B3.5 in the afternoon shows much more traffic going north (coming back from work).
