Modelling the Spatial Distribution of Commercial Vehicle Ownership: An Application to Windsor, Ontario

Commercial vehicles play an important role in the movement of goods in urban areas. Although they account 10 – 15 percent of the total daily urban traffic (Hunt and Stefan, 2007), they have a higher impact on the performance of the transportation system. More specifically commercial vehicles on average have significantly larger gross vehicle weight (GVW), and as such contribute to the deterioration of pavement and air quality. The spatial distribution of commercial vehicles, as in the case of private vehicles, is a key determinant of the level of traffic volume that can be observed on the road network. To date, analysis to analyze the spatial location of commercial vehicles is limited. Most of the existing efforts have been focused on private vehicles instead. Identifying the factors that explain the prevalence of specific types of urban commercial vehicles at a given location in the city could help transportation modelers to devise effective travel demand models. In this paper the determinants which lead to the prevalence of a specific type of commercial vehicles (as derived from the GVW classes) in a given zone are investigated. A multinomial logit (MNL) model is formulated to test the influence of various zonal and vehicle characteristics on the prevalence of commercial vehicles in traffic analysis zones (TAZs). When considering a set of alternative TAZs, the MNL model predicts the probability of finding commercial vehicle type t in TAZ i. To our knowledge, no previous study has developed such model. The remainder of this paper is organized as follows. The next section highlights the data used in this analysis. It also discusses the specification of the MNL model. This will be followed by a section to present and discuss the statistical results. Finally, a conclusion to our study will be provided in the last section.
