| 摘要： | The main objective of NCHRP Project 08-80/NCFRP Project 25 was to study the relationship between freight trip generation (FTG) and land use and . . . to develop a handbook that provides improved freight trip generation rates, or equivalent metrics, for different land use characteristics related to freight facilities and commercial operations to better inform state and local decision-making. As part of that quest, the research: consolidated the available FTG models in an electronic database to assist practitioners interested in using these models; undertook an in depth examination of the key concepts to identify the most appropriate approaches to develop and apply FTG models; and, used data previously collected by the team to estimate establishment-level FTG models for a number of case studies. This process led to the identification of a number of premises considered to be central to the development of FTG models able to satisfy the needs of both transportation planning and traffic impact analyses. The most important of these premises is the need to make a distinction between FTG, i.e., the generation of vehicle trips, and freight generation (FG), i.e., the generation of the cargo that is transported by the vehicle trips. FG is an expression of economic activity performed at a business establishment by which input materials are processed and transformed generating an output that, in most cases, is transported elsewhere for further processing, storage, distribution, or consumption. FTG, on the other hand, is the result of the logistic decisions concerning how best to transport the FG in terms of shipment size, frequency of deliveries, and the vehicle/mode used. Of great importance is the shippers ability to change shipment size to minimize total logistic costs, as it allows shippers and carriers to increase the cargo transported (the FG) without proportionally increasing the corresponding FTG. As a result, FTG cannot be universally assumed to be proportional to busine |
