Based on the experimental data in Figure 5 and combined with the Boltzmann superposition principle [33], the isochronous curve of rocks shown in Figure 6 is obtained.

The isochronous curve for polycarbonate is shown in Fig.
This required us to predict the average travel time between some missing coordinates in order to build the isochronous curves. With this aim, the kriging method (Phatarapon et al., 2015), which is based on regression methods and theories of probability, weights ([lambda]) the sampled points, multiplying them by the value of the variable of interest.
Using GIS, it was possible to define the isochronous curves obtained by applying the Kriging model using socio-demographic information on the study area: 404,805 inhabitants living in 95,361 households in an area of about 39.3 Km2, according to socioeconomic stratum, where stratum 1 is households with low economic capacity and stratum 6 are households with high economic capacity (See Figure 2).
