Intra-Agent Heterogeneity in Urban Freight Distribution: the Case of Own-Account Operators

This article, from a special issue on freight transportation, focuses on urban freight distribution and how policy characteristics impact owner-operator agents’ behavior. Policy characteristics include time windows, number of loading and unloading bays, and entrance characteristics. The authors note that this population is among the least-studied operators in freight transportation, primarily because of the work required to acquire relevant data to study their preferences and behavior. The authors report on their study, conducted in the limited traffic zone in Rome’s (Italy) city center in 2009. This area imposes an entrance fee on all non-residents’ vehicles, including freight delivery vehicles. The data set included: general information on the respondent, company characteristics, and stated ranking exercises. The ranking data were subsequently transformed in choice data. The authors describe owner-operators’ preferences as they emerge from the state ranking exercises and propose a systematic comparison among them via willingness-to-pay measures. They stress that an appropriate treatment of heterogeneity is necessary to obtain undistorted and reliable policy forecasts, which are subsequently fed to micro-simulation models used to support decision-making processes.
