| The current life in urban centers has led to increasing and demanding freight requirements, and manufactures, retailers and other urban agents have thus tended towards more frequent and smaller deliveries, which result in a growing use of light freight vehicles (<3.5 ton). In this paper the authors characterize and analyse urban freight mobility. Based on a 2-city case, which gathers data from global positioning systems (GPS) and complementary interviews, the authors first propose a categorization of urban freight movement, after which the authors carry out a speed analysis. Finally, this multi-factor study allows us to link dangerous behavior (out-of-limit-speed) with movement characteristics. The authors confirm that routine movements lead to safer driving behavior, while the lack of patterns and of previous route planning promote higher and, even worse, out-of-limit speeds. The results of this research could make an important contribution for setting appropriate and more specific safety policies. | |
