Megaregion Truck Flow Estimation Model
| 项目名称： | Megaregion Truck Flow Estimation Model |
| 摘要： | Freight transportation has played a critical role in the development of megaregion economies. However, most of the existing freight studies have focused on goods movement at the national, state, or metropolitan levels. Megaregion freight transportation has not received much attention. One of the objectives of this research is to develop an analytical model for estimating megaregion truck flows, which will help to evaluate and improve freight mobility in megaregions. This research will review previous studies on this issue, identify available and ready-to-use freight datasets, and examine the state-of-practice methods for truck flow estimation. Based on the reviews and the available data, this research intends to develop a replicable method to explore the spatial and temporal patterns of commodities moved by truck in megaregions. It will also develop an analytical framework to load the commodities carried by truck onto a road network, which is a spatial integration of the Federal Highway Administration (FHWA)�s Freight Analysis Framework (FAF) and the megaregion freight transportation facilities. It selects Texas Triangle as an empirical case to demonstrate the implementation of the megaregion truck flow model. The commodity data will be obtained from the FAF, state transportation agencies, MPOs, and other related sources. Since FAF data ignores truck movement details within a large metropolitan area, the centroids in the FAF�s zonal system will be redesigned by adding internal zones and multiple freight external points such as seaports, airports, rail yards and highway entry-exit points in the large metropolitan area represented by this FAF centroid. Further, the FAF and the road networks of the large metropolitan area will be integrated by matching their links and incorporating their attributes; a user equilibrium (UE) freight model will be developed to estimate the freight value by link of the freight network. The link truck values calculated in this research will support the evaluation of freight mobility and facilitate the decision making process of policy makers for megaregion freight transportation. |
