Estimating Emissions from Regional Freight Delivery under Different Urban Development Scenarios

Abstract

This study aims to develop a regional freight-shipment model to forecast freight movement within freight-delivery regions and examine the relationship between regional freight-shipment activities and the related environmental problems such as greenhouse gas emissions. A methodology for freight distribution and collection within geographical regions is proposed, in which a significantly large number of freight demand or supply points needs to be served. This problem can be considered as a large-scale vehicle routing problem and solved by an asymptotic approximation method. A set of closed-form formulas is constructed to obtain a near-optimal total travel distance of a fleet of trucks from multiple distribution centers. A case study is conducted to forecast regional freight-delivery cost in the selected metropolitan areas in the United States. Numerical results under three urban development scenarios show that the proposed methodology can be used to estimate the total cost and related vehicle CO 2 emissions effectively.

Reorganization of industrial zones as a factor of sustainable development of urban areas

“…Lee I., Hwang S. W. [7] emphasize the decline of the manufacturing industry in cities as a global phenomenon that leaves behind abandoned industrial zones. The presence of abandoned and unused industrial zones encourages many cities to implement various reconstruction strategies [7].…”

“…Lee I., Hwang S. W. [7] emphasize the decline of the manufacturing industry in cities as a global phenomenon that leaves behind abandoned industrial zones. The presence of abandoned and unused industrial zones encourages many cities to implement various reconstruction strategies [7]. Asian cities, experiencing similar changes in industry and urban landscape, in order to revitalize abandoned industrial areas and focus on the population, choose the construction of multi-purpose commercial complexes that combine culture and entertainment as a redevelopment strategy.…”

Assignment of Freight Truck Shipment on the U.S. Highway Network

“…A dynamic programming approach and deterministic shortest path heuristics were presented to conduct numerical tests based on U.S. urban networks. More recently, Lee and Hwang [24] constructed a large-scale freight truck routing model to investigate a regional freight shipment problem and its relationship to environmental issues, such as greenhouse gas emissions. A set of case studies was provided to estimate total freight delivery costs and associated vehicle emissions in 22 major metropolitan areas in the United States.…”
