AbstractThis paper explores the relations between perceived urban freight delivery parking issues and commercial establishment characteristics, their associated distribution channels, delivery operation patterns and local land use patterns using a structural equations modeling framework. The main motivation is to test hypothesized relations between urban freight delivery parking issues and the aforementioned factors as a way to perform an indirect, but informative, freight infrastructure adequacy assessment. The hypothesized model structure makes it possible to examine, for example, if the distribution channel characteristics (e.g., the most frequently used delivery vehicle type) can be linked to a certain type of parking behavior/preference, due to operation requirements, which could result in perceived urban freight delivery parking issues.The chosen variables are assembled from a plethora of sources. Establishment characteristics include size, number of employees and weekly deliveries, with this data being gathered using an establishment-based freight survey. Distribution channels are characterized by the predominant delivery agent and vehicle type. Delivery operations are represented by the most common parking location. Finally, the perceived issues include vehicles blocking other vehicles, lack of loading/unloading bays and illegal parking in loading/unloading bays. The land use data is obtained from parking records, the OpenStreetMap repository, the Portuguese National Statistics Institute (e.g., information on residents) and the City Council’s retail establishments’ census.The results show that, in general, the hypothesized relationships hold true. Perceived urban freight delivery parking issues are a function of the establishment characteristics, their distribution channels and delivery operations patterns. Weekly deliveries are dependent on distribution channels and establishment characteristics. Finally, weekly deliveries’ frequency did not seem to influence the perceived urban freight delivery parking issues. This supports the hypothesis that the retailers’ judgement is not biased by the frequency of said operations.
