7 Speed Limits EDA

In order to explore this part of the dataset, we first need to look at the number of accidents that took place at different speed limits (here is the description of the data).

We will also select out the postvz_sl as well as the shape_leng as they do not matter for our analysis. We will only consider the streets to refer to a strange case later in the chapter (figure 7.1).

As seen in this plot, most accidents happened at the speed limit of 25mph. It has to be noted that all the streets in New York have a 25mph speed limit since 2014 unless otherwise posted. Hence, what the higher speed limits are indicating are the accidents that has happended in highways or particular streets.

Source

Now, if you are wondering about the speed limits that fall below 25mph, we can see that indeed there exists a 0mph speed limit! The following table along with the pictures are demonstrating what we are talking about, by considering a couple of examples: ***

#> Parsed with column specification:
#> cols(
#>   .default = col_double(),
#>   DATE = col_date(format = ""),
#>   CRASH_TIME = col_time(format = ""),
#>   postvz_sg = col_character(),
#>   street = col_character()
#> )
#> See spec(...) for full column specifications.

Figure 7.1: Examples of Entrance and Exit with Zero Speed Limits

As you can see from street name found in the table above, the speed limit of 0 mph seems to be an entrance/exit from a street indicated in the description by “ENTRANCE”, “EXIT” and their abbreviations, “EN” and “ET”, which could either mean a side road next to the highway or, as the example above shows, a simple entrance and an exit. The exact meaning of ET is not clear, as well as the one of EN, however, we can also imagine that it may be a particular cross-road that has either special traffic regulations due to road constructions or other reasons. Nevertheless, we will disregard any speed limit below 25 later on at the modelling stage.

7.0.1 Relative Injury/Death

Given the the accident distributions over the speed limits we have seen in the plot just above, it would not make much sense to have a look at the absolute total number of persons injured or killed in a car crashes, as we will clearly have more in the 25mph speed limit, since it is the one with the highest number of accidents by far. Therefore, it is more reasonable to directly look at the relative injury and death per each speed limit.

7.0.1.1 Speed limit and persons_injured

In the first graph, we find some shocking results, as in the streets having speed limits between 0mph and 25mph, despite having very few accidents, there has been a large chance of relative injury.

7.0.1.2 Speed limit and persons_killed

When it comes to fatalities, the observation we made in the first plot about the chance of relative injuries occurring in streets with a low-speed limit only holds in case of fatalities for streets in which there was a speed limit of 0 mph. This makes sense, as they are the entrance of exit from the highway/main road where collisions could occur frequently, however this is a mere hypothesis and may not be true.

7.0.2 Contributing factor & Accidents

As seen earlier in the variable seletion chapter, we have chosen three contributing factors to look at for our eda.

Looking at the plots please mind the “free” scales. The scales are every axis has a different range. Here the absolute values are not relevant but rather than the proportion of the cases in which that variable caused an accidents in that speed limit vs the times it was absent. Another point to note is that we only analyze injuries and not deaths, but this should not be a problem, as anyways we do not have many deaths in our datasets (221 instances).

7.0.2.1 pedestrian_bicylist_other

According to both lasso_reg and random_for, the variable which had the strongest relationship with injuries or deaths is pedestrian_bicylist_other which represents an accident caused by error and confusion of the pedestrian or the bicyclist (we have shortened variable names with more than 3 words in eda_weather). This should hold for speed limits that have a low vlues, but you do not regularly expect pedestrians or bicyclist to be present on high-speed roads (i.e. highways), hence our focus is to see the spread between the speed limits lower or equal to 25 vs above 25 by looking at all the speed limits at once.

As we have expected, at lower speed limits there are fewer accidents. At the speed limit of 15 miles an hour, there are no accidents with the cause of the injury being this reason, which makes sense as there are not many accidents at that speed limit anyways. We can see that after the speed limit exceeds 40mph the reason is not causing many accidents, which makes sense, however, what is surprising is that there are still accidents at the speed limit of 30mph and 35mph with this factor, which is not something we expect.

7.0.2.2 following_too_closely

One variable that correlates with the speed limit is “following_too_closely”, meaning that the accident has happened because there was not enough distance between the two cars. This could either have to do with the lack of respect of speed limit of the street in which the accident happened, but not only.

Here we can see that at the speed limits of 45 and 50, the “Yes” for following too closely is making up almost half of “No” and this proportion is the largest at 45. Meaning that in accidents in which there were injuries, the proportion of times in which the one driver was following the car before them too closely are almost equal to the half of the times in which they were not.

7.0.2.3 unsafe_speed

An even more relevant contributing factor to look is the accident caused by unsafe_speed. Despite not being in the top 3 most important variables from the lasso regression, and only partially present in the MeanDecreaseGini of Random Forest, we have chosen it to see if it can tell us anything.

There is not a pattern indicating a higher propotion of the accidents due to the high speed compared to the accidents in which no one was going too fast, not even considering the increase in speed limits. We do have to note that in the speed of 50mph, the proportion seems to be slightly higher than the others, but it does not seem to be significant.
