Title:
A Simulation Model for Assessing the Impact of Climate Change on Transportation and the Economy in Canada
Abstract:
It is widely argued that severe weather events and episodes of poor weather conditions (cold snaps and heat waves) have significant impacts on regional economies and transportation systems. Several studies have focused on quantifying this relation from observed data. However, very little has been done to simulate and assess the long-term impacts of climate change on regional transportation systems and economies. This is due to the lack of simulation models that are able to link changes in weather events to transportation system performance and inter-regional trade flows. This paper reports on the development of CLIMATE-C, a simulation tool for CLimate IMpact Assessment on Transportation and the Economy in Canada. Linkages between transportation and economy are handled through a random based multi-regional input-output model (RBMRIO), which predicts inter-regional trade flows by truck and rail among the 76 economic regions of Canada and for 43 commodities. On the other hand, the influence of weather on transportation is handled through speed adjustment factors that account for the reduction in travel speeds due to changes in the frequency of various weather events. Therefore, changes in the frequency of weather events translate into travel delays, which in turn influence trade flows between regions. Sensitivity analysis with the implemented model illustrated its ability to assess the impact of climate change on transportation and the economy in Canada.
