Distribution in Large Urban Centers: Mobility Disabilities Generating Complex Logistics

Abstract

Urban population growth in developing countries has transformed mobility in large urban centers more dramatic. In this way, the routine of companies and citizens suggest that restrictions of urban mobility seem to affect the traditional business distribution in large cities. Therefore, this research proposes to analyze how the literature has dealt with the impact of deficiencies in urban mobility on logistic capacities. It was possible to verify that the deficiencies of urban mobility have led to economic activities dispersion by the environment, which implies in an increase of small vehicles fleet and, consequently, resulting in the worse in mobility of goods and people in these cities.

q-Weibull distributions describing commercial service routes

“…The mechanism responsible for this will be presented in the section 3.2 and it is related to different patterns of degree mixture for inand out-distribution. (8), (9), and (10). The best-fitting shown in a was obtained for the incoming connections of routes using q-Weibull distribution with the parameters reported on the third column of Table 1.…”

“…Table 1: Table of parameters. The parameters used for the adjusts present on Figure 3 given by equations (8), (9), and (10) are present in the third and fourth columns. At fifth and sixth columns, the parameters are related to adjusts shown on Figure 6, where were used weighted cumulative versions (discussed below) of those degree distributions present on Figure 2.…”

“…Structure and dynamics of systems arranged as directed networks composed of flows have attracted attention in many fields [1,2,3,4,5]. Among studies of infrastructure systems, modes of transport have a particular interest since they are straightforwardly related to human mobility [6,7], spreading disease [8], shipping [9,10], etc. Besides that, in recent years there have been many studies investigating structural features of transport systems through the application of complex network theory [11,12,13,14,15,16,17], which in turn offers materials for related works mainly on dynamical processes occurring on these structures.…”

“…Cumulative versions (circles) of distributions shown in previous figure. Lines are adjusts following equations (8),(9), and(10). The best-fitting shown in a was obtained for the incoming connections of routes using q-Weibull distribution with the parameters reported on the third column of Table1.…”
