Upgrading a Commercial Vehicle Model Using a Roadside Truck Survey: Application for the City of Edmonton

The movement of goods and services are central to the economy of the City of Edmonton. The City understood the importance of incorporating commercial vehicle movements as part of their overall planning process and developed a commercial vehicle model in 2006. Since the development of the original model, no further analysis has been conducted to ensure that the model is estimating commercial vehicle movements accurately. Preferably, an updated establishment-based survey would be collected and a complete re-estimation of the tour-based microsimulation model would be performed. However, this research aims to provide a cost effective approach to upgrade the City of Edmonton's commercial vehicle model to reflect current conditions using the truck counts collected in a roadside truck survey. This research has provided the City with an effective iterative adjustment procedure which has resulted in a model which outperforms the original model and is re-calibrated to the new road count data.
