Freight Transportation Model
The effective incorporation of freight transportation considerations into the transportation planning process is extremely important because the freight system is a crucial contributor to a vibrant economy, quality of life, and efforts to combat global warming and climate change. The freight transportation system is important because of both its positive and negative contributions to modern life. An efficient freight transportation system is a necessary condition for economic competitiveness, and for realising the full potential of economic globalisation. On the other hand, freight— along with the rest of the transportation sector—produces many negative externali- ties, which, in turn, generate community opposition to freight activities. These con- siderations acquire greater significance considering the major economic currents shaping the 21st Century. The freight system will have to be more responsive to user needs and expectations, and reduce the impacts of truck traffic, all with fewer re- sources for expansions in infra-structure capacity. In short, the freight transportation system will need to do more with less. This adds pressure to state transportation agencies to balance the conflicting objectives of the stakeholders involved and im- pacted by freight.
These challenges are compounded by the complexity of freight movements, and the lack of appropriate freight modelling methodologies. The lack of research and data concerning freight affects all facets of transportation demand analysis: generation of cargo, distribution, mode choice, and traffic assignment.
In order to get a better understanding of the variables driving the generation of freight demand, and their connection to land use, Singapore LTA is conducting extensive data collection effort and a freight transportation model development effort, which would help provide more accurate demand forecasts and better quantification of the traffic impacts from freight activity.
The overall purpose of this study is to develop a freight model which can identify freight and goods vehicle movement patterns in Singapore, with the following characteristics:
• A regional level model
• Using different data sources and freight driver surveys
• Secondary data and indirect approaches
• The model will interface with the LTA’s Strategic Transport Model
• The model will be in open source programming language (Python)
