Analysis of the Level of Service of Unloading Zones Using Diversity Measures in a Multiplex Network

Abstract

Unloading zones are a fundamental part of the infrastructure of urban freight transport. The location and accessibility of unloading zones to commercial establishments reduce the operating time and, consequently, the transportation costs. In general, unloading zones are located on-street and allocated by local authorities. In this context, this paper aims to evaluate the level of service of unloading zones. The research approach uses the diversity measures in a multiplex network to identify the level of service and cargo accessibility of unloading zones. An analysis is developed for the central area of Belo Horizonte (Brazil). The results indicate that unloading zones located up to 25 m from the establishments have a high accessibility and low level of service. In contrast, unloading zones located up to 100 m from the establishments have a low accessibility and high level of service. These results allow us to conclude that the planning process of the location of unloading zones in Belo Horizonte is flawed. In addition, the maximum distance from unloading zones to establishments must be 75 m, so that there is a balance between the accessibility and level of service.
