Seminar: Freight and Service Activity Generation Models in Urban Areas

The seminar, held in the Department of Political Sciences of the University Roma Tre, will see the participation of PhD student Diana Ramirez-Rios, from the Rensselaer Polytechnic Institute.

 

To understand the magnitude of freight and service activities (FSA) in urban areas it was necessary to study the impact of economic activity in metropolitan statistical areas (MSAs). One of the best ways to measure and predict the volume of cargo of different supply chains is by identifying the industry sector where the business belongs to, in accordance with the North American Industry Classification System (NAICS). This study provides an overall picture of these sectors, which have been categorized among Freight Intensive Sectors (FIS) and Service
Intensive Sectors (SIS).
By understanding the composition of number of establishments and employment in each NAICS through public data, it is possible to get a sense of FSA in the MSAs, at both FIS and SIS through establishment-level empirical models. This research is based upon the models developed by Holguín-Veras et al. (2017) to estimate Freight Generation, Freight Trip Generation and Service Trip Attraction. These models were estimated using survey data from establishments in New York City and New York State Capital Region. The results were generated for different MSAs in the United States, and results have been compared to some international cases. The main findings provide FSA metrics to quantify freight and service in urban areas.

 

Diana Ramirez-Rios is a PhD student and Research Assistant at Rensselaer Polytechnic Institute, in Transportation Engineering. She obtained her BS-MS in Industrial Engineering at Universidad del Norte, in Barranquilla, Colombia. Her research interests are in Urban Freight Transportation, Supply Chains and Humanitarian Logistics. Her recent work includes freight trip generation modeling, behavioral models of freight transportation initiatives and last mile delivery trends, disaster relief models and empirical studies on human suffering. Has experience in teaching, research and consulting. She was designated in 2015 as a Colciencias Scholar by the Governor of the Atlantico Department in Colombia. Was also selected as a finalist for the 2017 Lee Schipper Memorial Scholarship and was part of the team of finalists for the 2017 Franz Edelman Award, who developed the Off-hour Delivery Program in New York City.
