+ This dataset was used in [1] and donated by the authors of that
3
+ paper. Accelerometer data was collected on a smartphone installed
4
+ inside a vehicle using a flexible suction holder near the
5
+ dashboard. An expert was responsible for driving the vehicle while
6
+ the device ran an Android application called Asfault [2], developed
7
+ specifically to store the current asphalt condition continuously
8
+ over time. Asfault stores the time-stamp of the collected data,
9
+ acceleration forces in along the three physical axes, latitude,
10
+ longitude, and velocity.
11
+
12
+ The acceleration forces are given by the accelerometer sensor of
13
+ the device and are the data used for the classification task.
14
+ Latitude, longitude, and velocity are given by the GPS and are used
15
+ to locate the collected/classified data. Each one of this
16
+ information is a different continuous time series. A sampling rate
17
+ of 100 Hz was used for each time series. It is important to note
18
+ that the Android system does not guarantee a perfect precision on
19
+ the interval between readings. This means that when we choose a
20
+ sampling rate of 100 Hz, the device should output between 95 and
21
+ 105 observations per second.
22
+
23
+ For this data, the (X,Y,Z) acceleration time series are converted
24
+ into a univariate time series that represents the acceleration
25
+ magnitude.
26
+
27
+ In order to obtain labeled data, the Asfault application allows the
28
+ expert to inform the pavement condition before collecting the data.
29
+ To guarantee the integrity of data, Asfault also records videos of
30
+ the road over the data collection using the built-in camera. Thus,
31
+ it is possible to perform the analysis of these videos to confirm
32
+ the class labels assigned by the expert.
33
+
34
+ The datasets were collected in the Brazilian cities of Sao Carlos,
35
+ Ribeirao Preto, Araraquara, and Maringa using a medium sized
36
+ hatchback car (Hyundai i30) and two different devices (Samsung
37
+ Galaxy A5 and Samsung S7).
38
+
39
+ The problem AsphaltObstacles involves the identification of four
40
+ common obstacles in the region of data collection. It has the
41
+ following class labels: raised_crosswalk (160 cases);
42
+ raised_markers (187 cases); speed_bump (212 cases); and
43
+ vertical_patch (222 cases). Data is variable length, minimum 111
44
+ observations, maximum 736. The data is split randomly into 50/50
45
+ default train series. The data can be resampled without bias.
46
+
47
+ The best result for the Asphalt-Obstacles dataset was achieved by
48
+ DTW distance with 81.13\% accuracy (Table 9 of [1])
